(<a href="http://www.youtube.com/watch?v=I9im8SpWB1M">http://www.youtube.com/watch?v=I9im8SpWB1M</a>) I enjoyed the lively exchanges between the two intelligent, well-spoken men. After the formal presentations, the moderator allowed each to question the other. Hitchins, actually, preferred to let the audience throw the questions, but Turek had one that he repeated many times because Hitchins appeared to miss the point or dodge the question.</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">(I say "appeared" because a response was made, but not recognized by Turek (and, me, at the time.) Certainly, Turek, and some people who posted to the website, thought Hutchins was ignoring the point. Turek kept repeating the question.</p> <p class="MsoNormal"><span style="mso-spacerun:yes"> </span></p> <p class="MsoNormal">The question was, "Since you [Christopher] are a materialist, explain to me how carbon atoms and benzene molecules can bring about notions of truth, love, empathy, and justice. You can't. Those concepts require a higher entity to instil them in us, a judge of what is moral."</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">Repeatedly, Hitchins took issue--took offence, really--with the notion that religious people feel that they have to subjugate and enslave themselves to a deity who tells them that they are wicked and need to be cleansed, who demands obedience and worship, and so on. It's humiliating to feel that humans aren't capable of coming up with an appreciation of doing the right thing without a God having to demand it on penalty of eternal torture or human sacrifice.</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">Turek kept firing the carbon atoms and benzene molecules, to no avail. Hitchins wouldn't bite. (That's not exactly true. He did say that it's up to Turek to establish the insufficiency of the materialist position, but this was lost in the exchange.)</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">I'd like to respond. Turek's basic point is that God is the source of all goodness (and, presumably Satan is the source of all that isn't good) so that knowledge of good and bad has to be imposed from above. (He went so far as <span style="mso-spacerun:yes"> </span>to say the existence of mathematics, information, and the DNA molecule required a deity, but let's keep it simple.) His point is that a bunch of carbon atoms and benzene molecules can't, without divine help, generate sensations of empathy.</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">There are two answers I could give.</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">One is "I don't know." The problem with that answer, unfortunately, is that deists jump on it triumphantly and say, "Right. Only God can do it." Their response is nonsense, of course. The existence of God does not depend on whether I or anyone else "knows" the answer or has a theoretical explanation. The existence of God does not depend on how far along in our thinking of science we are. </p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">Going deeper, we could say that the deist's answer was just as inadequate. The deist could have said, "Gzort does it" or "Shublefumph does it" or "Satan does it" for that matter. When the deist says, "You don't know the answer, but I do. It was God." the deists isn't advancing toward knowledge. He's just putting a name to the cause of the phenomenon.</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">A problem with answering "I don't know" in a debate is that you always have to get sidetracked to explain that "I don't know" does not weaken the intellectual position. </p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">(Hitchins responded a couple of times that had Turek asked the question a couple of thousand years ago, he wouldn't have been using the terms "molecule" and "DNA". Turek became exasperated, saying (in effect), "So what? Just answer the question.")</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">The second answer to how the accumulation of atoms that composes us instils in us ethics and morality appears, at first, to reverse the issue. An atheist could say, "evidently the laws of chemistry and physics <i style="mso-bidi-font-style:normal">do</i> allow for it, and even if you deists don't know how, that doesn't shake my satisfaction that notions of morality are innate to humans (and to primates, and possibly to other organisms, too.)</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">An atheist shouldn't want to say this in a debate, because it's really putting the "I don't know" in the deist's mouth and taking unfair advantage.</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">So let's take this a little farther, but examine something simpler (but just as intellectually significant.) Consider the action of moving your finger. You think, "I'm going to move my finger." Then you move it. How does the thought trigger the actual, physical action? This is a deep mystery. A scientist could respond, "When I think, some electrochemical exchange happens somewhere in my brain which causes an electrical signal to go down the nerve and move the muscle." But the mystery still exists. How did the desire to move the finger cause the electrochemical exchange? We could get into an infinite regress here. But that's no reason to insist that God is in the details. </p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">Consider the Big Bang (which Turek mentioned often.) "How did the universe start from nothing?" the deists scream. We could respond, "Well, not from nothing. Some mass was there."<span style="mso-spacerun:yes"> </span>or "Well, not from nothing, some energy was there." or "Well, negative mass-energy went one way and positive mass-energy <span style="mso-spacerun:yes"> </span>went the other way, so it still adds to zero." But we always have a "what started it" issue: how did the initial mass, the initial energy, the initial impetus to change things get there?</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">Infinite regress. There will always be an infinite regress. That does not mean there is a deity. </p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">So, back to Turek's question: How do we humans have concepts of right and wrong? Evolution could help in the discussion. We could propose that organisms without such understanding did not, in the long run, survive. Natural selection among sentient beings could select for cooperation, for adherence to (or, at least, contemplation of) the Golden Rule.</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">I'm interested in the question. Recent studies with apes, monkeys, dogs, cows, and cats suggest that non-human animals have concepts of morality. Who's side of the debate does that help? The deist just says, "God gave them morality, too." Case closed.</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">Are molecules and the laws of physics and chemistry sufficient for the appearance of morals in people. Evidently yes, Hitchins says. </p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">I agree.</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">-Rob</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">P.S. Hitchins did point out, quite eloquently, that the religious authorities have another problem. Even if one were to accept that there <i style="mso-bidi-font-style:normal">were</i> and entity to get it started, there is no way for them to link that to their conclusion that <i style="mso-bidi-font-style:normal">this same</i> entity interacts with us daily, hears our thoughts when we are sleeping or awake, judges our thoughts and actions, demands that we worship it, and so on. </p>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-71041019359632543942011-02-13T05:06:00.000-08:002011-02-13T05:23:37.623-08:00<div style="text-align: center;"><br /></div><p class="MsoNormal"><span style="mso-tab-count:1"> </span>A friend returned from a fascinating visit to the SNO lab, the slow neutron observatory in Sudbury, Ontario, Canada. He described the long ride down into the depths of the mine on the rickety, open elevator, and the remarkable equipment he observed. He made one statement, though, that bears examining, because it's a popular misconception. </p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>He said, "You could feel yourself getting heavier."</p><p class="MsoNormal"> Because he was progressing toward the centre of the Earth, he expected to weigh more.</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>This is a fallacy, though. He would weigh less. In fact, although weight follows the familiar inverse-square law outside, weight is proportional to the radius inside. It drops linearly.</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>Here's why. (It's a standard university calculus question, but you don't need calculus to see.)</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>First, the quick, intuitive answer. How much would you weigh at the centre? Zero, of course, because the mass is pulling you in all directions, each molecule on one side being cancelled by one on the other.</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>Since you weigh more than zero at the surface, and zero at the middle, either it decreases as you go down, or increases for a while before decreasing. Where is the logical turnaround point? (The surface, of course.) Also, it doesn't make sense to say that the force of gravity keeps increasing all the way to the centre, then instantly becomes zero when you travel that last nanometre to the absolute centre.</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>OK, so now that we expect a decreasing graph of weight versus distance from centre (radius), why is it linear.</p><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgheaNqEyLJy6Iav4uTtGYoaOgNTghfwFdXXNBM_Ki9B_UYaxxkiOJ2U_OtK9DGrlhP3AW8pyMoMpyo_xuh8jhHJh46U-9qhfETzHcpt6TAP5vBHIyXAyLKtuXp0S66f73CyghEhA/s320/gravity+down+a+mine.bmp" style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 320px; height: 120px;" border="0" alt="" id="BLOGGER_PHOTO_ID_5573162314259509266" /> <p class="MsoNormal"><span style="mso-tab-count:1"><br /></span></p><p class="MsoNormal"><span style="mso-tab-count:1"> </span>The answer is easiest to understand if you consider the force inside a shell. Pretend the Earth is a perfectly spherical egg. You're inside. How much do you weigh? Then answer: zero everywhere. Pretend you are a two-thirds down to the centre. The mass below your feet is twice as far away as the mass above your head, so pulls a quarter strength (inverse-square law). But there is four times as much of the shell below you than above. Four times as much pulling at one-quarter the force…cancels out. Same with side-to-side, of course.</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>(This is analogous to the electric field inside a charged sphere--zero everywhere.)</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>So, now you're down a mineshaft. All the shells above you are cancelled out by mass below you, farther out than your radius. What's left is only the ground beneath your feet, acting as if it's all at the centre. Mass goes as volume, radius cubed. So as you go down, the mass of the sphere beneath your feet is decreasing by radius cubed, but acting stronger on you by radius squared.</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>Result, the force of gravity is decreasing by the radius to the first power. You feel lighter down a mine shaft.</p>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-86225536512151850622011-01-31T14:58:00.000-08:002011-01-31T15:34:22.625-08:00What if Tests Don't Test What You Want to Test?<div><br /></div><div>When my daughter was in elementary school, she came home with a couple of quizzes on which she'd scored zero or one out of ten. The topic was "greater than / less than". There were two columns of numbers and she had to draw a greater than or less than sign between them. (e.g. 5 less than 9).<div><br /></div><div>I created similar quiz sheets. I cut out a bunch of little squares with the mathematical signs on them, and gave her a glue stick. Instead of drawing the sign, she could glue it in. She put in all the signs correctly, every time. Ten out of ten.</div><div><br /></div><div>So my daughter's dismal marks on the quizzes did not indicate whether she knew the difference between less than and greater than. They did not indicate whether she knew which sign to use. They indicated whether she had the capability of drawing the sign. </div><div><br /></div><div>As you might guess, my daughter has a learning disability. But the lesson here goes beyond that. Teachers of all grades should be aware that many times the questions on quizzes and exams are testing something other than what the examiner intended to test.</div><div><br /></div><div>I remembered the episode with my daughter when I made a summative exam for my Workplace Math class last week. (I had taken over the class from a teacher midway through the course.) The exam consisted of 30 questions down the left of a large sheet of paper with answer boxes on the right. I gave the students all the answers on slips of paper, and a glue stick. They were to arrange the slips in the proper places and glue them into the boxes. (Students could write the answers if they wanted.) The student with the lowest mark in the course to that point (38%), scored a 70%, the class average on the exam. </div><div><br /></div><div>I wonder what the earlier evaluations, the ones that rated him dead last, were actually testing.</div><div><br /></div><div><br /></div></div>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-8956460845363108752010-11-12T05:34:00.000-08:002011-01-31T14:50:50.297-08:00<span class="Apple-style-span" style="font-family: Georgia, 'Bitstream Charter', serif; line-height: 24px; "><p style="background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: transparent; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; margin-top: 0px; margin-right: 0px; margin-bottom: 24px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; vertical-align: baseline; "><span class="Apple-style-span">Faster Than The Wind</span></p><p style="background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: transparent; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; margin-top: 0px; margin-right: 0px; margin-bottom: 24px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; vertical-align: baseline; "><span class="Apple-style-span">I was wrong. A year ago, my future son-in-law asked me if a sailboat could travel faster than the wind. I said no. If the sailboat were travelling faster than the wind, then, to a person on the boat, the wind would seem to be coming from the opposite direction. This applies to downwind sailing, not to tacking against the wind. My mistake was going with my intuition, not my analysis.</span></p><p style="background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: transparent; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; margin-top: 0px; margin-right: 0px; margin-bottom: 24px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; vertical-align: baseline; "><span class="Apple-style-span">I have studied many websites explaining how a sailboat can go (at an upwind angle) faster than the wind. Most explanations are flawed. Many quote Bernoulli’s principle, which isn’t an explanation. In the same way, physicists have stopped using Bernoulli’s principle to explain why planes can fly. (Otherwise, how could they fly upside down?)</span></p><p style="background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: transparent; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; margin-top: 0px; margin-right: 0px; margin-bottom: 24px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; vertical-align: baseline; "><span class="Apple-style-span">Some websites contain text or comments from readers linking the claim that a wind-propelled craft, on land or water, can travel faster than the wind to a claim of perpetual motion. This, of course, is faulty thinking. Such a vehicle is getting its energy from the wind, and the wind is losing energy to the craft. No wind, no motion. Nothing magic about that.</span></p><p style="background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: transparent; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; margin-top: 0px; margin-right: 0px; margin-bottom: 24px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; vertical-align: baseline; "><span class="Apple-style-span">But, for those still worried about what pushes a boat faster than the wind, here’s a simple explanation. First, what pushes a tacking sailboat forward against the wind? The answer is, the <u>water</u>. The wind pushes the sail, which is attached to the boat. The sail pushes the boat, which includes the keel. The keel pushes the water back (at a slight angle) and the water pushes the boat forward [Newton's 3rd, action and reaction.] Remove the keel (e.g.. raise the centerboard on a tiny sailboat) and the wind shoves the boat back, no matter which direction the boat is facing.</span></p><p style="background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: transparent; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; margin-top: 0px; margin-right: 0px; margin-bottom: 24px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; vertical-align: baseline; "><span class="Apple-style-span">The faster a tacking sailboat travels, the greater the force of the wind on the sail, the greater the force of the keel on the water, the greater the forward force of the water on the boat. The limiting factor is not the speed of the wind but the friction of the water on the hull.</span></p><p style="background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: transparent; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; margin-top: 0px; margin-right: 0px; margin-bottom: 24px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; vertical-align: baseline; "><span class="Apple-style-span">Going downwind faster than the wind (DWFTTW) is a little more anti-intuitive. A great blog entry with videos that demonstrates that an object can move faster than the object (and wind is millions of “objects”, air molecules) that propels it is http://dwfttw.blogspot.com/.</span></p></span>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-9575250652241541522010-11-12T05:31:00.000-08:002010-11-12T06:06:03.652-08:00<span class="Apple-style-span" style="font-family: Georgia, 'Bitstream Charter', serif; line-height: 24px; "><p style="background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: transparent; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; margin-top: 0px; margin-right: 0px; margin-bottom: 24px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; vertical-align: baseline; "><span class="Apple-style-span">Phony e-mail "News"</span></p><p style="background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: transparent; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; margin-top: 0px; margin-right: 0px; margin-bottom: 24px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; vertical-align: baseline; "><span class="Apple-style-span">On Remembrance Day yesterday, someone I love and trust sent me a wonderful email about the origin of the bugle call Taps.

Yet Homeland Security Secretary Janet Napolitano repeated it the claim in 2009, then corrected herself. And Sharron Angle, a Tea Party-backed candidate in Nevada, made that claim anew.) The trouble is, receiving the stuff in email from a person you trust is different from seeing it on the front page of the National Inquirer at the supermarket checkout.</span></p><p style="background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: transparent; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; margin-top: 0px; margin-right: 0px; margin-bottom: 24px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; vertical-align: baseline; "><span class="Apple-style-span">I try to keep passing on the other-side-of-the-issue to people who send me preposterous reports.

If there are two species in existence today--call them species A and B--that evolutionists propose have a common ancestor, we should be able to find bones in the fossil record of the common ancestor. The ancestor would be the "link" between them and, presumably, have some of the attributes of each species.<o:p></o:p></span></span></p> <p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto; line-height:normal"><span style="font-family:"Times New Roman","serif"; mso-fareast-Times New Roman";mso-fareast-language: EN-CAfont-family:";font-size:12.0pt;"><span class="Apple-style-span" style="color:#CCCCCC;">There are many, many transitional fossils. We have fossils of creatures that are intermediary between humans and apes. (Note the often misunderstood point: humans did not evolve from chimps. Chimps and humans evolved from a common ancestor. We were </span><u><span class="Apple-style-span" style="color:#CCCCCC;">never</span></u><span class="Apple-style-span" style="color:#CCCCCC;"> apes. The phrase "Man descended from the apes" is not correct, and not part of evolution theory. Modern apes and modern humans had a common ancestor. Any chimpanzee teaching her offspring that chimps descended from humans is making the equivalent mistake. )<o:p></o:p></span></span></p> <p class="MsoNormal" style="margin-bottom:12.0pt;line-height:15.6pt"><span style="font-family:"Times New Roman","serif";mso-fareast-Times New Roman";mso-fareast-language:EN-CAfont-family:";font-size:12.0pt;"><span class="Apple-style-span" style="color:#CCCCCC;">We have fossils of a link between fish and land animals. </span><i><span class="Apple-style-span" style="color:#CCCCCC;">Tiktaalik</span></i><span class="Apple-style-span" style="color:#CCCCCC;">, discovered in Canada in 2004 had physical features from both, allowing the huge fish to live in very shallow water. It has the cranial features associated with both fish and land-living animals, including a neck (i.e. the earliest fossil with a neck).

Get it for sure.) In addition to the hand sensors you have likely seen, Wii Fit includes a balance board. The Wii board can sense shifts in weight. The way you can try to walk tightropes, get through obstacle courses, ski slalom courses, and bicycle around the Wii island.</div><div><br /></div><div>There are dozens of games that are very imaginative, and extremely well done. They allow you to work on your balance, your strength, and endurance. Some, like the stepping, running, and biking, allow you to work up a sweat. There are many little challenges to keep you thinking while you exercise. </div><div><br /></div><div>Speaking as a computer programmer, I am very impressed by the 3-D graphics, the flexibility, and the intelligence built into the programs. </div><div><br /></div><div>Now: For those who do the free biking, here are the locations of the 20 balloons and the fastest route I've found to get them. I just got off the "bike" and had them in 20:24:25, a new record for me. (I know one place I lost a second.)</div><div><br /></div><div>If you want to find them yourself, don't read any farther.</div><div><br /></div><div>To get the balloons in a fast time, start near the top of the mountain, at the balloon on the grass by the stone pillars. That way you head downhill at the start and don't have to climb the mountain again. The free ride starts where you last stopped, so prepare by going up the mountain and stopping after popping that balloon. (Press B to stop there, and exit.)</div><div><br /></div><div>Also, have you found that the A button rings a bell that attracts a pet? With it alongside you, if you are pointing at a nearby balloon and ring the bell, the dog or cat runs ahead and pops the balloon while you are turning around. Don't ring too soon, though. </div><div><br /></div><div>OK, here's the fastest route I've found.</div><div>1. On the mountain path, by the pillars. Head down...</div><div>2. Behind the castle. Keep going around and pick up a pet.</div><div>3. Curve around the pond, up on the grass on the right before you get to the tunnel.</div><div>4. Cut down slope to tunnel. You will survive and pet will follow. After tunnel, cut right and skirt the cliff to a raised grassy strip. Balloon at end.</div><div>5. Go back, up sand path through tunnel with iron bridge. Curve right at exit of bridge. Balloon is in the field.</div><div>6. Cut right toward the big rock. Pass it on the right; go across the two suspension bridges, cut up the grass through the tunnel to balloon on sandy plateau.</div><div>7. Go back, follow cliff around to left...balloon near the rock.</div><div>8. Cut right. This is the trickiest. Coast down and cut sharply around the FIRST fence (passing it with your right shoulder.) Balloon is at far end of a narrow grassy strip. Careful when you turn around.</div><div>9. Reverse, follow lower fence; cut around it at end and find balloon near the water by the left side of the bridge.</div><div>10. Cross bridge. (You will probably lose your pet.) Cut left at town and take first grass path between houses to balloon.</div><div>11. Follow around houses to town square and up the ramp to the upper town. JUST BEFORE you go up, ring bell twice to summon pet.</div><div>12. After breaking balloon go back down the SAME ramp. At the bottom, ring bell again. Pet should come running up as you turn right. Head through town, turn down towards water at last street. Go behind last house on right to find balloon (on grass, near water.)</div><div>13. Follow black walk, then up to lighthouse. Pass left of lighthouse to balloon on the point.</div><div>14. Pick up road that goes around the island. Take immediate right after short tunnel. Balloon is on right side of pond.</div><div>15. Another balloon on left side of pond.</div><div>16. Cross road, up grass to ruins. Balloon behind ruins.</div><div>17. Out of ruins, continue on road through tunnel. Take immediate left down to balloon near water.</div><div>18. Follow shore along the sand. (Fastest along the harder, wet sand.) Balloon just past the first large rock with small tunnel in it.</div><div>19. Keep going toward end of sand. Go up the jump to the left of the next rock. Balloon on top.</div><div>20. Keep going past balloon. Jump down. Keep going. Pick up pet just before final large rock. Follow around the left. Tell pet to break the last balloon.</div><div><br /></div><div>Now you should have a few minutes to start back to the grass for the long trek back for your next run. (Or try this run in reverse!)</div><div><br /></div><div>Good luck.</div><div><br /></div><div><br /></div><div><br /></div></div>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-60902186876373145442010-04-15T05:48:00.000-07:002010-05-27T04:35:34.901-07:00<p class="MsoNormal"><span style="mso-tab-count:1"> </span>The other day, my friend Ray called Obama a Nazi, a socialist, a danger to Western democracy, a man intent on bringing down the United States. He shied away from calling him the Antichrist.</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>I couldn't believe that a person I thought was an intelligent, rational, free-thinking person would make that preposterous statement. So, what led him to it? I conclude that the 'free-thinking' attribute was probably wrong. He was trumpeting the standard line spouted by Beck, Palin, the Tea Partiers, and other radical right types. (I do not claim that Beck, Palin, and every Tea Party member thinks the same thing. But if asked to take a stand for or against Ray's statement, I propose that they would be Ray-supporters. So I will continue to generalize.)</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>"Ray," I said, "think for a moment. You are just saying stuff other people say, without thinking about it."</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>"Look at the bank bailouts," he said.</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>The bailouts were started by Bush, not Obama. Did Obama allocate more funds? Yes. But why? Not to line the pockets of the filthy rich CEO's. Obama is as upset as everyone at those robber-barons getting multimillion-dollar salaries for incompetent management of assets. Many of those assets came from Main Street, and represent many honest Americans' pension plans and life savings. By keeping the banks afloat, the bailout safeguarded the financial futures of millions of ordinary people. </p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>According to the NYTimes:<span style="line-height:115%;font-size:8.0pt;"> </span><span class="apple-style-span"><span style="line-height: 115%;Georgia","serif";font-family:";font-size:9.5pt;color:black;">Losses from the $700 billion financial rescue are expected to be much less than initially feared, according to a Treasury report and government audit late last year. Besides banks’ repayment of their bailout money with interest, the government also has made money by selling the bank warrants that it held as collateral for its loans to the institutions.</span></span> <span style="mso-spacerun:yes"> </span><span style="mso-spacerun:yes"><br />- <span style=" line-height: 12px; font-size:8pt;"><a href="http://www.nytimes.com/2010/01/12/business/economy/12bailout.html">(http://www.nytimes.com/2010/01/12/business/economy/12bailout.html</a>)</span></span></p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>"What about healthcare?" Ray demanded. "That's socialism."</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>Well, so is using taxpayer's dollars for building roads. Everyone pays, even those who don't use the roads. (Of course, everyone benefits. The trucks bringing food to your grocery story use the roads, even if you don't.) And tax money funds schools. (Even if you have no children, presumably you want your doctor to have had a good education.) The idea of a decent universal healthcare system is that the country benefits <b style="mso-bidi-font-weight:normal">as a whole</b> from the good health of its citizens. Economy of scale considerations suggest that the total amount spent by the citizens of the country could go down. (I acknowledge that the two sides disagree on that point. Certainly, prevention costs less than cure, so if people see doctors early, before conditions worsen, every person who is spared a hospital stay helps save the system money.) </p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>I guess what bothers me the most is that Ray echoes the people who shout the apple pie slogans: no taxation, no driver's licenses, no restrictions on guns, no restrictions on freedom, no government interference in anyone's lives, etc. etc.</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>No income tax? Right: who is going to build the roads? Who is going to pay for the navy that guards the shores? Does everyone then teach their kids at home? (Ray: "People can freely combine and pool their money for a community school." Me: "Give me a break! Would the US have gained prominence in so many areas if it hadn't had government-funded schools?")</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>Regarding government influence: Do you want no standards for quality of food? No standards for toxin-free paint or microbe-free water?</p> <p class="MsoNormal"><span style="mso-tab-count:1"> </span>What I'd prefer is that you Tea Partiers, you local militia folk, you radical Right people just come out and say it. Be honest. You guys don't want a black president; you guys don't want to contribute to the common good of your country (except on your terms); and, basically, you want anyone who thinks differently from you to get the hell out of <b style="mso-bidi-font-weight:normal">your</b> country.</p><p class="MsoNormal"></p><p class="MsoNormal">P.S. McCain said, regarding working with Democrats on other big items on Obama's agenda. "<span class="apple-style-span"><span style="line-height:115%;Helvetica","sans-serif"; font-family:";font-size:9.0pt;color:black;">There will be no cooperation for the rest of this year." </span></span>Although he softened the statement after receiving criticism, it speaks volumes about whether Republicans care about governing the country. The country can go to hell before any Republican will participate in honest government. Sabotaging the president is their highest priority.</p><p class="MsoNormal">P.P.S. Many in the Tea Party movement do not shy away from calling Obama the Antichrist.</p><p></p>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-25677618705514903322010-04-03T15:43:00.001-07:002010-11-12T06:24:55.087-08:00Lying for Christ ... Three questions.<div><br /><div>I just received an email that contained a religious PowerPoint presentation created, apparently, by Bro. Joe. It begins with a "news" article about an Egyptian man who kills his wife for reading the Bible, then kills and buries his two kids. Fifteen days later people go to bury an uncle and find the girls alive. They describe a Christ figure as feeding them after their interment. </div><div><br /></div><div>On subsequent pages, the a commentator (not Bro. Joe) expands the story. He claims that the people in Egypt are "outraged" and that the "man will be executed in July." Also, the writer predicts that "Muslim leaders are going to have a hard time to figure out what to do with this."</div><div><br /></div><div>Of course, the story never happened. According to scopes.com, the email was first seen in 2004, and its creator has been identified (the wife of a pastor). It's a fabrication. [Subsequent note: snopes.com now reports that the pastor's wife says her husband received the story via email himself.-Rob]</div><div><br /></div><div>It's a lie. There were no news reports about this event; no one was sentenced to be executed for this crime.</div><div><br /></div><div>Now for the first question. If the writer wants people to believe in God and Christ, is she justified in creating a phony story to convince people of Christ's presence and miraculous powers? I think not. Christ used fables to get a point across, but I doubt if he used phony news reports. I doubt if he would have sanctioned such an ends-justifies-the-means approach to spreading his message.</div><div><br /></div><div>The second question is related. Was the pastor's wife trying to gain converts? My guess is that she is preaching to the choir. Will any non-Christian read it and decide to become a Christian? Surely not. </div><div><br /></div><div>Besides, it's my guess that she sends out such God's message emails to friends who are already Christians. (I have relatives that do that.) So the desire is either to make them feel good or to reinforce an "us versus them" perception. Hence the anti-Muslim slant. Part of the reason for sending it out is fear.</div><div><br /></div><div>Now the third question. Why did Joe make the woman's email the foundation of a PowerPoint presentation and send it out to <i>his</i> friends? I will assume that Joe believes the story was true. In a dozen pages following the story he urges the reader, many times, to send the slides on to many others. Why is only bad news forwarded? he asks. Why jokes but not messages about God? As I read, I could feel his despair. He bribes people with "Send this on and God will abundantly reward you."</div><div><br /></div><div>By the end, instead of the beautiful scenery over which he had pasted his text, he was putting images of Christ in the clouds, with lines of scripture beneath. Poor desperate Bro. Joe.</div><div><br /></div><div>So, about the entire production. I find myself annoyed with the creator of the phony news article. No girls in Egypt were found alive after being buried for 15 days.

By Lemuel Gulliver, First a Surgeon, and then a Captain of several Ships</span></span></span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size:medium;">. </span></span><o:p></o:p></i></b></span><b><span class="Apple-style-span" style="font-family:'times new roman';"><i></i></span></b></p> <p class="MsoNormal"><span class="Apple-style-span" style=" ;font-family:'times new roman';">Most people have heard of Gulliver's visit to Lilliput, home of the little people. Many don't realize that gulliver travelled to several other lands, too. Swift wrote the book as a satire and condemnation of the injustices of society in the century before the great democratic revolutions. But Swift had to be careful. He couldn't just come right out and say, for example, that the king was an ass, or that the British House of Lords was composed of imbeciles, or that justices of the peace were corrupt. Doing so could have got him thrown in jail, or worse.</span></p> <p class="MsoNormal"><span class="Apple-style-span" style="font-family:'times new roman';">Instead, he had Gulliver visit lands where the king was an ass and the appointed governing body was composed of imbeciles. When challenged, he could always say that he'd written a book of fiction. He wasn't talking about home, for goodness sake.</span></p> <p class="MsoNormal"><span class="Apple-style-span" style="font-family:'times new roman';">Isaac Newton had revolutionized science. He showed that the universe runs on simple mathematical laws. He broke down the distinction between heaven and earth by showing that the same laws of physics that govern the actions of objects on Earth apply to the planets. Prior to Newton, nature was mysterious, and scientists (or natural philosophers, as they were more properly called) were limited to explaining Earthly phenomena. The Heavens were governed by their own laws, and why not? Heaven was the realm of God, and God should not be subject to the same laws that constrained the behaviours of Earthly objects.</span></p> <p class="MsoNormal"><span class="Apple-style-span" style="font-family:'times new roman';">A generation before Newton, Kepler found that the planetary orbits follow mathematical rules. The planets travel on elliptical paths at varying speed. (Their speed increases as they get closer to the sun.) And Kepler found a fascinating, but mysterious relationship: the cube of the a planet's average radius of orbit divided by the square of the planet's period of orbit is the same for all planets. In math lingo, T-squared varies directly with R-cubed.</span></p> <p class="MsoNormal"><span class="Apple-style-span" style="font-family:'times new roman';">Newton used this relationship, Kepler's elliptical orbits, and the calculus that Newton invented while on summer holidays when he was an undergrad at Cambridge University to come up with the Law of Gravity. He could demonstrate that the same force that makes apples fall keeps the planets in orbit around the sun. When he published his discoveries (some twenty years after he made them) he became an instant celebrity.</span></p> <p class="MsoNormal"><span class="Apple-style-span" style="font-family:'times new roman';">So, back to Gulliver. On his voyage, he landed at Laputa, where astronomers studied the heavenly bodies through great telescopes. In Swift's time, no moons of Mars had been discovered, so he decided to pretend that Laputian astronomers made a fascinating discovery. Read this:</span></p> <p class="MsoNormal"><span class="apple-style-span"><span style=" line-height:115%;font-size:10.0pt;color:black;"><span class="Apple-style-span" style="font-family:arial;">They have discovered two lesser stars, or satellites, which revolve about Mars; whereof the innermost is distant from the centre of the primary planet exactly three of his diameters, and the outermost, five; the former revolves in the space of ten hours, and the latter in twenty-one and a half; so that the squares of their periodical times are very near in the same proportion with the cubes of their distance from the centre of Mars; which evidently shows them to be governed by the same law of gravitation that influences the other heavenly bodies.</span></span><o:p></o:p></span></p> <p class="MsoNormal"><span class="apple-style-span"><span style="line-height: 115%; color:black;"><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size:medium;">Did you see what he said? Kepler's T-squared/R-cubed law holds for the moons of Mars, showing them to follow Newton's Law of Universal Gravitation!</span><o:p></o:p></span></span></span></p> <p class="MsoNormal"><span class="Apple-style-span" style="font-family:'times new roman';">I think this speaks volumes about Swift's society. Swift counted on his readers knowing Kepler's and Newton's Laws. He knew that his characters had instant credibility if they were included in Newton's great intellectual revolution.</span></p> <p class="MsoNormal"><span class="Apple-style-span" style="font-family:'times new roman';">How many authors of fiction today assume their readers would be as intellectually accomplished?</span></p></div>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-24196524968190973122010-03-25T18:36:00.001-07:002010-03-25T19:38:05.167-07:00<div>Tidy rooms...</div><div><br /></div><div>My wife regularly asks my daughter Debbie to tidy her bedroom.

I figure "It is tidy" means one of these:</div><div>1. it's good enough for me</div><div>2. this matches the definition of "tidy"</div><div>3. don't tell me what to do.</div><div><br /></div><div><br /></div><div>To be sure, number 3 applies as a general rule to any suggestion my wife makes to my daughter. "Don't tell me what to do" is a given. But I've come to the conclusion that Debbie actually believes that a room qualifies as tidy even if the floor is covered in paper, empty water bottles, underwear, spilled cat litter, books, CDs, and overturned containers.</div><div><br /></div><div>Look, my den is often messy. I freely confess it. But, during those times, I don't call it "tidy". Our bedroom is often a mess. (My wife doesn't follow the adage "let she who is without sin cast the first stone.") But I admit the fact.</div><div><br /></div><div>Debbie's definition of "tidy" is far from my wife's (and mine, but I stay out of it.) There will never be a day when my wife will be able to look in Debbie's room and say, "My, your room is tidy."</div><div><br /></div><div>And there is only one or two days a year when our bedroom is tidy, and it only stays that way for 24 hours. But that's another story.</div><div><br /></div><div><br /></div><div><br /><br /><div><br /></div><div><br /></div></div>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-15334873947452913112010-03-23T18:50:00.000-07:002010-03-23T19:08:45.893-07:00Congratulations US Congress ...<div><br /><div>As a Canadian, I was pleased to see the Democrats prevail and pass a universal health care bill. Over the past year, I couldn't believe the vitriol from the Republicans. I was disgusted by the distortions, and misinformation, and outright lies about what the various versions of the bill contained and ramifications of ensuring that Americans can get access to health care.</div><div> </div><div>I don't mind paying higher taxes than Americans in return for health care. One of my daughters had a brain tumor operation. No one asked for money for the operation and the three weeks in hospital. My other daughter went in for a seizure-caused dislocated shoulder. We just show our health card, and walk in. If I have a problem, I go to my doctor, flash my card, and that's it. The important thing is that it's the same for everyone, not just those that can afford insurance.</div><div><br /></div><div>The fact that, in the US, some workers at insurance companies admitted that they automatically reject claims until appealed appalled me. I found it hard to believe that the country with the highest standard of living in the world wasn't embarrassed to see some of its citizens bankrupted by health problems, or worse, see some of its citizens having to forgo medical treatments because they were financially worse off.</div><div><br /></div><div> That a country wouldn't take care of its citizens on such a basic issue as health care ... well, congratulations for seeing the light. </div><div><br /></div><div>Shame on Republicans for NOT EVEN ONE voting for the bill. NOT EVEN ONE.</div><div><br /></div><div>Defeating Obama was more important than doing the right thing for your country. I realize that Republicans will jump all over that statement, saying that they WERE doing the right thing for the country by voting against the bill. But it sure didn't look that way from here.</div><div><br /></div><div><br /></div><div><br /></div></div>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-21316766661244454612010-03-11T20:25:00.000-08:002010-05-27T04:13:17.933-07:00<p class="MsoNormal">The Mentalist ... Getting Stupid</p><p class="MsoNormal">I'm getting more and more disappointed with The Mentalist. I cheered the concept at the start, especially when Patrick Jayne said, in the first episode, "There are no such things as psychics." The problem is, the police work in the show is getting far too stupid.</p> <p class="MsoNormal">Cases in point:</p> <p class="MsoNormal">Case 1</p> <p class="MsoNormal">In one episode, the dead victim is in a field, shot from a distance. But where did he stand? We hear Jayne call, "He stood here." Jayne is standing behind a scarecrow, waving its arms. Of course, Jayne would be standing right on top, and thus destroying, possible evidence.</p> <p class="MsoNormal">Case 2</p><p class="MsoNormal">A couple of episodes ago (January or February, 2010), The Mentalist never realized that a person was lying to him. Kinda destroys the very concept of The Mentalist, doesn't it.</p><p class="MsoNormal">Case 3 (Last week, March 4)</p> <p class="MsoNormal">A <i>second</i> victim dies, right in front of the head of the crime unit (Teresa Lisbon). She sees him drop, eyes open, not breathing, not talking. Does she start CPR? Does she check for a pulse. No. She holds her hand in front of his face and cries, "How many fingers am I holding up?"</p> <p class="MsoNormal">Case 4 (Tonight, March 11)</p> <p class="MsoNormal">A scientist in a bio lab became exposed to a virus and died. A few hours later, Jayne pulls a prank, admittedly clever, to catch the killer. But it involved announcing to at least 40 other people that they have now been exposed, that they should call their loved ones and say good-bye, and make their final arrangements. They only have an hour or so to live.</p> <p class="MsoNormal">It was a fabrication, of course, but how many lives did he just hurt? How many people are going to sue him for pain and suffering.</p> <p class="MsoNormal">Going back to Case 3. Where was an editor or consultant to say, "That's stupid. A supposedly experienced person is not going to say 'how many fingers?' to a dead person." Surely Robbin Tunney, if she really knew her role, would balk, and announce, "My character wouldn't say that." </p>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-66330752835209233242010-03-09T05:28:00.000-08:002010-03-09T05:50:45.975-08:00<p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style="font-family:arial;"><span class="Apple-style-span" style="font-size:-webkit-xxx-large;"></span></span></p><span class="Apple-style-span" style="font-family:arial;"><p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style="font-family:Georgia, serif;"><span class="Apple-style-span" style="font-size: -webkit-xxx-large;"></span></span></p><span class="Apple-style-span" style="font-family:Georgia, serif;"><p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span style="font-size:10.0pt;font-family:"Georgia","serif";mso-fareast-font-family: "Times New Roman";mso-bidi-font-family:"Times New Roman";color:black; mso-fareast-language:EN-CA">Dealing with unruly students<o:p></o:p></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span style="font-size:10.0pt;font-family:"Georgia","serif";mso-fareast-font-family: "Times New Roman";mso-bidi-font-family:"Times New Roman";color:black; mso-fareast-language:EN-CA"><o:p> </o:p></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span style="font-size:10.0pt;font-family:"Georgia","serif";mso-fareast-font-family: "Times New Roman";mso-bidi-font-family:"Times New Roman";color:black; mso-fareast-language:EN-CA">I have been retired from teaching or four years.

And that's how it should be. Students should be in class because they want to be, not because they have to be. A student isn't doing me a favour by showing up. I am doing him a favour by sharing my expertise.

Usually, if you are having trouble with the student, they are too. The phone call will be a sharing episode. Then say, "Here's something that might work. Suppose I tell him that he's not allowed to come to class. He's not kicked out of the course. He just has to learn on his own." Then explain the plan. Parents have always agreed to try it.

My comments are on the use of the label "Christian". We hear of "Christian Schools". In Canada, we allow two school systems, the public school system (inclusive, open to everyone) and the Roman Catholic School system. Non-Catholics can, theoretically, attend (because tax dollars go to the RC boards), but it's catholic education. Then there are the schools not supported by tax dollars. The label "Christian" school goes to the private schools that are run by Baptists, for example, or other fundamentalist groups. In general usage, the term "a Christian education" does not apply to either of the two official school systems. </o:p></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span style="font-family:"Georgia","serif";mso-fareast-font-family: "Times New Roman";mso-bidi-Times New Roman"; mso-fareast-language:EN-CAfont-family:";font-size:10.0pt;color:black;">The fundamentalists have confiscated the word "Christian".

I have a couple of friends who take Genesis literally. There was an actual Adam and Eve, they say. One of them was surprised to hear that man have the same number of ribs as women. The other truly believes the Earth is not much older than six thousand years.</p> <p class="MsoNormal">These are not morons--they are intelligent, rational people with good jobs (earning more than me!) But they deny evolution with a vehemence that astounds me. No, I'll take that back. I am not astounded by what adherence to a religious belief does. Witness suicide bombers who feel that<br />1. non-believers deserve to die, and<br />2. they themselves will go to eternal paradise by killing infidels with them when they go.</p> <p class="MsoNormal">My two creationist friends aren't in that league. That is, contrary to some creationists I see on the web, they don't feel the need to make everyone believe, or else.</p> <p class="MsoNormal">I feel sorry for creationists when I assess what they have to give up to maintain their beliefs. Although they might not concede this list, to deny evolution, they must ignore accepted facts in astronomy, geology, the fossil record, comparative anatomy, comparative physiology, genetics, molecular biology, continental drift, and embryology, at a minimum.</p> <p class="MsoNormal">One of them even says, "There is no evidence for evolution." This floors me! The evidence for evolution is overwhelming, converging from so many disciplines. How can he say this?</p> <p class="MsoNormal">What a wealth of knowledge people have to give up to maintain absolute consistency with a religious belief. So sad!</p>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-69435067914778242882010-03-09T03:39:00.000-08:002010-03-09T03:43:24.680-08:00<p class="MsoNormal">Sing the Damn Note!</p> <p class="MsoNormal">I don't watch Idol because I can't stand the type of singing that everyone seems to do nowadays. Instead of singing the note as the composer wrote it, today's performers hit about five notes per syllable<span style="mso-spacerun:yes"> </span>near the correct one, eventually (one hopes) lingering on right one long enough to demonstrate that they are familiar with the tune. I know Streisand did that (in moderation) years ago. Karen Carpenter used to scoop a note here or there, and Petula Clark would put a grace note in occasionally.</p> <p class="MsoNormal">But now the instruction to "Make the song your own" means that the tune gets destroyed. I am especially irked when this happens to Christmas carols. When "ger" in "Away In The Manger" is awarded six notes, I feel like yelling "Sing the damn note".</p> <p class="MsoNormal">That's one of the reasons I like show tunes. I realize I'm showing my age here, but when Shirley Jones sung a song, she hit the notes and put on the consonants. Same with the quality performs in "Cats", or "Phantom" or "Les Mis". </p><p class="MsoNormal">Of course, we have to give the singers who perform the national anthem permission to butcher the song. That's expected.</p><p class="MsoNormal"><br /></p> <span class="Apple-style-span" style="font-family:Calibri, sans-serif;font-size:130%;"><span class="Apple-style-span" style="font-size: 15px; line-height: 17px;"><br /></span></span>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-88299323681608205762010-03-08T20:33:00.000-08:002010-03-08T21:05:13.562-08:00Conspiracy theorists<div><br /></div><div>Glenn Beck on the radio; Mark Steyn in Macleans magazine; Conrad Black in the National Post...

Just as the people who think that the US flew planes into the Twin Towers, that man has not set foot on the moon, that the Holocaust didn't happen, and so on. I sometimes wonder how intelligent people can let themselves be led to ridiculous, unsupported positions.</div><div><br /></div><div>Of course, these guys are saying the same thing about me; namely, that I've been sucked in by all the baloney and believe that the Earth is getting warmer.

Another deluded scientist has made a mistake (or is lying)? </div><div><br /></div><div>For the record: I have had a cottage a few hours north of Toronto since 1976, and grew up at my parents' cottage before that. The lake temperature used to peak at 80 degrees F on or around August 1, and stay there for a day or two before starting to cool. In each of the last two years, my lake got to 80 F by July 13, and stayed that warm for over two weeks. And there are new birds in the forest.

These memory locations are combined to represent bigger numbers using binary arithmetic. For example 0010 is 2, 0111 is 7, and 1000 is 8. Is there any way of altering and determing the polarity of the magnetism? If there were, then "north-up" could be a 2, "north-down" could be a 1, and no magnetism would be a 0. <div><br />That way, the computer could work in base three. A 2 would be 0002, a 7 would be 0021, and an eight 0022. It took two digits to represent an 8 instead of four (not counting the leading zeros.)<br /><br /></div><div>In binary, the biggest 4 digit number is 1111, which is 15. So sixteen numbers (0 to 15) can be represented with 4 digits. In base three, however, the biggest 4 digit number would be 2222, which represents 80. Many more numbers (i.e. data) could be packed into the same memory space.</div><div><br />Is anybody working on base three computers?</div>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-33445373143534134892010-03-06T07:18:00.001-08:002010-03-08T21:05:47.173-08:00<p class="MsoNormal">Amazing? Not</p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal">I propose a ban on the use of the word 'amazing'. Just today I heard the following:</p> <p class="MsoNormal">The figure skater's performance was amazing.<br />The Olympics were amazing.<br />Crosby's goal was amazing.<br /><i style="mso-bidi-font-style:normal">Avatar</i> was amazing.<br />The book was amazing.<br />The video was simply amazing.<br />The blueberry cheesecake was amazing.<br />Human reaction time is amazing.<br />The hummingbird was amazing.<br />The [sensitivity of a] mousetrap was amazing.<br />A girl said her boyfriend was amazing, but didn't clarify.<br />The same girl said her girlfriend was amazing to her.</p> <p class="MsoNormal">I'm ready to scream the next time I hear the word. The problem is, of course, that the word is used so widely that it has lost all meaning. To amaze is to overwhelm with surprise or sudden wonder. But people now use it to mean excellent, interesting, better than expected, higher/lower/cooler/warmer/drier/wetter, and very tasty. Human reaction time might be incredibly fast, but it is what it is, so one should not be amazed. Same with the hummingbird, but not that it can hover. If it tried to hover and fell...<i style="mso-bidi-font-style:normal">that</i> should be amazing. </p> <p class="MsoNormal">I agree that a hockey player like Ovetchkin can score an amazing goal, like when I see him put the puck through an opponent's legs, twirl around the guy, pick it up again, slip it into his skates to keep it away from the goalie's poke check, then kick it up to his stick, and pop it over the goalie's shoulder with a one-handed shot. Something that makes me blurt out, "Oh!" or "Wow" should rank as amazing. </p> <p class="MsoNormal">But not everything else.</p>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-76643638432420415702010-03-06T06:13:00.000-08:002010-03-08T21:06:02.519-08:00<p class="MsoNormal">How Many Dimensions Are There?</p> <p class="MsoNormal">We have three physical dimensions: length, width, and height. A mathematician or physicist might represent them by x, y, and z. </p> <p class="MsoNormal">In his Theory of Relativity, Einstein used time as a dimension, expressing the position of an object in space-time with four co-ordinates: x, y, z, and t. Hence the phrase "time is the fourth dimension."</p> <p class="MsoNormal">Remember that the number of dimensions is just a convenience. Einstein's formulas, using four dimensions, described the universe better than Newton's equations.</p> <p class="MsoNormal">You may have heard of string theory using eleven dimensions. What does this mean? Why eleven? Here's a quick explanation.</p> <p class="MsoNormal">An application of the laws of conservation of energy and conservation of momentum, in senior high school physics, is calculating the final velocities of two colliding balls, given the balls' initial masses and velocities. (And the angle between them, technically included in the word "velocity".) There are two unknowns, the final velocities of each object, and two equations to use. You always need the same number of equations as unknowns.</p> <p class="MsoNormal">What if there are three balls? You need three equations to find the three final velocities. But we don't have a third equation. This is the famous Three Body Problem. It's unsolved: physicists can't compute an exact answer. </p> <p class="MsoNormal">But nature can! How does nature figure out what happens to three simultaneously interacting objects? It's clear that nature <i style="mso-bidi-font-style:normal">does</i> know, because this situation comes up all the time. The sun, moon, and Earth are simultaneously interacting. (An interaction is one object exerting a force on another, and all three objects have gravity, which extends to infinity.)</p> <p class="MsoNormal">Physicists attack the problem by dealing with the bodies in pairs, or approximating the situation by saying that the smallest object doesn't influence the others very much. But it would be nice to have a third equation, to get absolute answers instead of numerical approximations.</p> <p class="MsoNormal">A special three-body question that can be solved by students is if one object comes in and hits two identical objects, like two balls touching and the third arriving on the mid-line between them. Because the situation is symmetrical, you can find an answer. (The third equation is that the final speed on one ball equals the final speed of the other, through symmetry.)</p> <p class="MsoNormal">So you can solve more complex questions if symmetry is involved. Remember this fact.</p> <p class="MsoNormal">Now picture a circle. It looks the same from all angles. Perfect symmetry. Even a small circle is the same as a large circle, in one respect, because a small circle is the large circle viewed from farther back.</p> <p class="MsoNormal">How about a square and a diamond? Are they the same? Sure: a diamond is a square rotated. </p> <p class="MsoNormal">How about a square and a hexagon? (A hexagon has six equal sides.) You can't rotate a square or view it from a different angle and direction and see a hexagon. So in two dimensions, a square and a hexagon are different.</p> <p class="MsoNormal">Now use your imagination. If you illuminate a cube with a light directly overhead, the shadow is the shape of a square. But if you turn the cube, you can get a shadow the shape of a hexagon. (To convince yourself, draw a hexagon, and add the "missing lines" to make it look like a 3-D cube viewed at an angle.) </p> <p class="MsoNormal">So, if you think in three dimensions, a square and a hexagon are <i style="mso-bidi-font-style:normal">the same thing</i>. They're both 2-D shadows of the same 3-D object. The lesson here is that if you include an extra dimension in your considerations, you can sometimes find symmetries that didn't exist when you were working in fewer dimensions.</p> <p class="MsoNormal">And symmetry allows you to solve otherwise unsolvable equations, remember?</p> <p class="MsoNormal">The string theorists use eleven dimensions. Their equations are so complex, apparently, that they need eleven dimensions to give them enough symmetries to solve them.</p>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-77463740333820725392010-03-06T05:20:00.000-08:002010-03-08T21:06:20.502-08:00<p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span lang="EN-US" style="font-family:"Arial","sans-serif"; mso-fareast-Times New Roman";mso-ansi-language:EN-US;mso-fareast-language: EN-CAfont-family:";font-size:10.0pt;">Gun Control and American Over-reaction<o:p></o:p></span></p><p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span lang="EN-US" style="font-family:"Arial","sans-serif"; mso-fareast-Times New Roman";mso-ansi-language:EN-US;mso-fareast-language: EN-CAfont-family:";font-size:10.0pt;"><br /></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;">(Warning: stereotypes used in this dissertation!)</span></p><p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;"><br /></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;">Last night I had a discussion with a friend, Jim, about gun control.

Why? Because, Jim said, Obama was sneaking in legislation under the tax laws to take away people's guns. Jim was furious, and proceeded to bring up the right-to-bear-arms and denial-of-freedom-guaranteed-by-the-Founding-Fathers arguments.</span></p><p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;"><br /></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;">I did some research and it turned out that he was incensed over an internet hoax. (<a href="http://www.snopes.com/politics/guns/taxreturns.asp" title="http://www.snopes.com/politics/guns/taxreturns.asp CTRL + Click to follow link"><span style="mso-bidi-;font-size:11.0pt;color:blue;">http://www.snopes.com/politics/guns/taxreturns.asp</span></a>). There was a bill about licensing of firearms (HR 45: Blair Holt...) before Congress--nothing to do with Obama--that Jim thought would permit the government to enter private houses to check the firearms, but the bill said no such thing. A similar bill had been brought before, and never voted on. Likely, that will be the same result here.</span></p><p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;"><br /></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;">What I found surprising (shocking would be a better word, except that I'm no longer shocked because I've seen it so often) is how the barest hint of gun control provokes such a visceral reaction in (many) Americans that it trumps all other considerations. Jim argued that the reaction is against restriction on freedom itself. Okay, I'll buy that. But the scale of the reaction is way out of proportion to the "danger".</span></p><p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;"><br /></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;">First, the reaction is against the <u>mere suggestion</u> of something that <u>could possibly</u> be used by an <u>extremely totalitarian state</u> to remove all weapons from its citizens. In fact the first site I hit when I searched for Obama and gun control displayed his picture beside Hitler, Stalin, Mao, and Pol Pot. Such comparison is ludicrous because the president doesn't have the power over the legislative and judicial arms that those guys had.</span></p><p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;"><br /></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;">Second, there are many limitations on freedom in society that we (Canadians and Americans, both) tolerate. We accept having to contribute some income to the state (taxation), licensing our cars, being required to educate our children, and so on.</span></p><p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;"><br /></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;">Jim made a distinction between privilege and right. Owning guns wasn't a privilege; it was a right. He was on pretty solid ground there, except that the distinction has, historically and in practicality, been that "right" is what a someone demands and "privilege" is what someone else demands but doesn't matter much to me. We saw how society changed on the Smokers' Rights issue, where smoking changed from a right to a limited privilege.</span></p><p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;"><br /></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;">It seems to me, and to most Canadians (I claim), that the American defense of their "right" in the 2nd Amendment is far more vehement than their defense of any hint of infringement on any other right. The reaction looks, to Canadians, way out of proportion. And since we Canadians don't include the right to bear arms as a fundamental freedom, the fact that so many otherwise thoughtful, intelligent Americans demand the right to carry machine guns and rocket launchers down public streets looks preposterous and downright pathological.</span></p><p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;"><br /></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;">Am I exaggerating? Sure, but there is a continuous line between pea-shooters and nuclear weapons. Air pistols, semiautomatics, and the other types of weapons fill the gap. Individual Americans place the line between acceptable and unacceptable somewhere, and there is vast disagreement as to where.</span></p><p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;"><br /></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;">To Americans, I say that I accept that the right to bear arms is incorporated into the very fabric of the creation of your country, both to rid yourself of an oppressive regime and to defend yourself against external threats. So I can pardon the vehemence somewhat. But what's ironic (and scary) is that your vehemence is its own counterargument. Jim said it himself, "If Obama's going to restrict my right to carry a gun, I'll shoot him myself." The very fact that he made that declaration shows that he <i style="mso-bidi-font-style:normal">shouldn't</i> have the right to own a gun. My own Florida relative, visiting my cottage during an earlier presidential campaign years ago, was watching Jesse Jackson on the TV news. She blurted, "That man should be shot." I stared at her in disbelief. Compare her statement to "we should vote against that guy" or "someone should write an editorial against what he's saying". Her automatic reaction perfectly illustrated the difference between Canadians and Americans.</span></p><p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;"><br /></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;">I agree that I'm talking stereotypes. Many Americans favor gun control, and many Canadians are against the drive to register long guns in Canada.</span></p><p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;"><br /></span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"><span class="Apple-style-span" style=" ;font-family:Arial, sans-serif;font-size:13px;">But am I very far off the mark?</span></p> <p class="MsoNormal" style="margin-bottom:0cm;margin-bottom:.0001pt;line-height: normal"> </p> <p class="MsoNormal"><span lang="EN-US" style="mso-ansi-language:EN-US"><o:p> </o:p></span></p>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-40198236568438554982006-12-23T15:15:00.000-08:002010-03-06T05:39:13.496-08:00<div>Belief in God</div><div><br /></div>I just finished sending a comment to “Tim” (<a href="http://existence-of-god.com/author-information.html">http://existence-of-god.com/author-information.html</a>). Sorry, I don’t know any more about his name. Tim’s site provides a huge discussion of arguments for and against the existence of God. Each argument against God’s existence is refuted. The counter arguments, however, are very well presented, though, which is rare on “Evidence for God’s existence” sites.<div><br /> If you look down the left, you see links to other sites or pages arguing for God’s existence. You see links to proclamations that “So and so rejects atheism.” I don’t see any saying “So and so converts to atheism.” I would feel better had I seen these. I realize, though, that “Tim” has no wish to convince anyone of the unreasonableness of his belief in God. And therein, really, lies the problem. The ideal philosopher, the ideal searcher after truth, should not care whether the statement “A is B” is actually true. The ideal searcher after truth should not have an agenda to convince readers that his point of view is the (only) correct one.</div><div><br /> I am always suspicious of people’s objectivity when they have a strong belief in the truth of some statement, whether the statement is “We never went to the moon”, “HIV (virus) does not cause AIDS” or “God exists.” As I said before, though, I commend Tim for the depth of his coverage of both sides of the discussion.<br /><br /> I have a confession to make: I’m an atheist. As a high school physics teacher, I never stated this fact to my class. I taught that there is a separation of science from religion/philosophy/belief. I suggested that if there was any way to absolute truth, only religion could get there. I taught that science didn’t say anything about God; only that science’s goal was to come up with a useful, testable, non-divine explanation for observed phenomena. I never answered the question “Do you believe in God?”</div><div><br /> Now, having retired, I can concede that the concept of the existence of God just does not fly with me.</div><div><br /> One of the arguments for God’s existence is based on probability: the likelihood of the universe being precisely right for the development of intelligent life on Earth is so small that one concludes that there had to be a designer.</div><div><br /> But I use probabilities a different way. Most people follow the faith of their parents. What is the likelihood, of all the faiths on this planet, that the one my parents happened to believe is the only true faith? I don’t think I’m that lucky. The fact that most people believe the faith of their fathers leads me to the conclusion that the correctness of their faith is suspect.</div><div><br /> Related to that argument is the statement of humility: So many people believe in other religions, other Gods, other ways that the universe may have come to be, who am I to assume that my way is correct?<br /><br /> </div><div>Frankly, I find the certitude of believers disturbing. I can’t buy the existence of an entity watching me/us/humanity/the cosmos, caring what we do, (perhaps) interceding (on our behalf), desiring to be worshiped, judging us.</div><div><br /> A friend told me, “You are a good person. You have to believe in God because God is the source of all goodness.” Sorry, but I think you can be good without the need for a God (to set a standard, presumably, for ultimate goodness).</div><div><br /> And people say, “Yes, but in the Bible it says…” Again, I don’t mean any disrespect when I say that, not believing in the existence of God, I don’t accept the Bible to be the word of (any) God.<br /> I respect people’s belief in God. Fanatics apart, most people I meet are sincerely interested in doing good, sincerely interested in the welfare of others (not just their own kind or own religious group). If belief in a God helps them to be that way, good for them. When their loved ones die and they find solace in a belief that “God had other plans for them” or that they have “gone to a better place”, I’m happy for them. Perhaps I’m even a little envious of believers’ satisfaction, or the peace that a belief in a God has brought them.</div><div><br /> I concede that I might be better off if I believed in God. But that is not a valid reason for a belief. I don’t think you can say, “I believe it because it’s advantageous to do so.”</div><div><br /> So, do I believe in God? No, but if you do, that’s OK. As long as you don’t discriminate against others who believe differently from you.</div>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0tag:blogger.com,1999:blog-6866351.post-1138466147143780122006-01-28T08:35:00.000-08:002010-03-27T18:59:09.109-07:00Standard Accepted Knowledge<br /><br />In my last article I commented on the differences in positions held by scientists and non-scientists on whether Earth had been visited in the past by intelligent extraterrestrials. I use the term scientists widely, not referring to an occupation but to a state of mind.<div><br />No matter what your occupation, I call you a scientist if you look for answers by studying the evidence; if you test to see if proposed explanations work; and if you assume that there are reasonable, physical explanations first, before resorting to magic or far-out justifications for an extraordinary claim.</div><div><br />I made a statement that there is near universal agreement among scientists on the big issues. Here is a list of what I consider those issues to be.</div><div><br />Earth is a speck in the cosmos. There are likely to be many small, rocky planets orbiting stars, some of which will be similar to our sun. There are so many stars, there are bound to me many Earth-like planets at suitable distances from their sun that conditions were similar to those on early Earth.</div><div><br />Earth is old and changing. Continents drift around and collide. Mountains rise. Rivers cut canyons. Lakes and oceans fill up with debris that eventually becomes sedimentary rock. As you dig down through layers you reach older and older rock.</div><div><br />Life processes follow the laws of chemistry and physics. There is no process that requires “magic”. We don’t know all the processes, but are confident that they are “knowable”. (Consider the opposite. If, for example, some magical process causes the heart to beat, then we might as well stop trying to understand how the heart works!)</div><div><br />Life evolves. Little changes in short periods add up to bigger changes over long periods.</div><div><br />The laws of mathematics and physics apply everywhere. The formula for a circle and value of pi is the same on Mars. Magicians don’t do true magic: they are still constrained by the laws of physics. (While watching a magic show, everytime you ask yourself, “How did he do that?” you are applying this concept. You feel that there was a physical explanation, a “trick”. You didn’t see true magic.)</div><div><br />Matter is particulate. Substances are made of atoms that join to become molecules. (Atoms themselves are made of particles.)</div><div><br />The properties an object possesses depend on the observer. (This claim, for which there is much evidence, arises from relativity and quantum physics. Relativity deals with the big concepts of time, space, gravity, matter and energy; quantum physics with the behaviour of matter and energy at the tiniest level.<br /><br />I might as well mention the fringe items, too.</div><div><br />There are no ghosts, werewolves, vampires, living dead, mammoth spiders, King Kongs, Spidermen, invisible people, extraterrestrial aliens living amongst us.</div><div><br />Astrology is false.</div><div><br />There is no such thing as psychic ability. You can’t move objects by though alone. No one can actually read minds, see the future (rather than predict likelihoods), perceive present, past, or future events by other than the five senses.</div><div><br />Men HAVE landed on the moon (i.e. the landing in 1969 was not a hoax.)<br />Humans and dinosaurs did not inhabit the Earth at the same time.<br /><br />I expect many to disagree with me on many of this last list. In particular, countless people will cite amazing occurrences, coincidences, anecdotes, and “facts”. I will leave it as this: I have seen no repeatable, non-controversial evidence that convinces me that, for example, ESP exists. A million dollar prize is available for ANY purported psychic who can demonstrate ANY psychic ability. No one has yet been able to do it.</div><div><br />As much as we, scientists included, might wish for exceptional abilities, extraordinary creatures, and assistance from the stars, there is just no good evidence for any of it.</div>Robhttp://www.blogger.com/profile/00767893926828464727noreply@blogger.com0
