If you are talking about the shortening of telomeres through successive replications within a particular organism, no I don't. However that mechanism does not exist in the sexual gametes (egg and sperm). i.e. its reset every generation. And, if talking about precellular or simple asexually reproducing monocellualr organisms, it does not occur either. It appears to be an anti cancer guard, protecting against unrestrained proliferation of cells within an organism. It can fail - as the existence of cancer shows.

As well as the generalized condition of "death," one presumes...so it seems the ideal would be to be "forever young," as the song sings, or very carefully in the "middle golden mean way," as philosophers immortally caution -- and to keep seeking the tonic(s), but not from snake-oil sellers or our wonderful big pharma reps -- one wonders what that Nicholas Flammel found...

Was it just *that* power of 2, or did you memorize them all - out to particular value? Well, that;s a story in and of itself. I was reading one of those silly gee whiz math books as a 6th grader. It told the story of the king who was saved by a peasant boy and offered one of two forms of reward:$1 the first day of a month,$2 the second day,$3 the third day, the amount increasing by $1 each day for 30 days. Alternatively, the peasant boy would get 1 cent the first day, 2 cents the second day, 4 cents the third day, the amount doubling every day for 30 days. The book told the amount from each choice ($465 for the first,$10,737,418.23 from the second). The memorized both for the he@@ of it. Well, the second is 2^30 -1 cents, so all I had to do is add 1 cent and shift a couple of decimal places. The teacher looked it up in his CRC handbook and I was right.:) I tell my students that the second payment plan represents my minimum bribe for an improved grade. I will accept it as a lump sum. Funny, nobody has taken me up on the offer. ;)

There was no luck involved though, you know that do you not? An opportunity presented itself to you and you took full advantage of it. You know what Thomas Jefferson said about luck? "I am a great believer in luck, and I find the harder I work, the more I have of it." Hoist n’ Huzza! 8^) Yes, but as happens so often with wunderkind, the early progress wasn't followed by later achievement. I'm now 45 and a math professor of a mid-level university. While I am very good at learning new things and teaching them, I'm not so good at research (as it turns out). It's strange to think my first PhD was half my lifetime ago.*shrug* Anyway, thanks for the vote of confidence!

Every joule is exactly an eqivalent quantity of "that which can perform work". I'd highly recommend Feynman's discussion about energy in the first volume of his lectures. You might find it enlightening to see how one of the best physicists of the 20th century thought of these things. In particular, your question about the equality of all 'joules' is rather similar to a question about the equality of all 'grams'. Equality in what sense? Well, that gram over there is hydrogen and that over there is uranium. In what sense are they equal? A valid and non-trivial question worth thinking about. How profound. Maybe someday we can harness the power of the stars but so what? that is if our consciousness is nothing more than "matter among matter" or "special matter among average matter", which comes from energy which in turn has no intelligent source, then we are thrashing around and searching in vain. If the universe has no purpose or cause then it likewise can have no answer. What good is an answer to us if we are JUST matter, of no intelligent origin? Why does it matter if we are 'just matter'? Why would an intelligent origin of this matter make any difference? Why is the only meaning 'ultimate' meaning? If all we are is matter, doesn't that just show how amazing matter can be? Why is the only 'purpose' the purpose of the whole universe? Can we not make our own purpose? What happens if the ultimate purpose is something we dislike? Can we not still choose what is best for us and make that our purpose? Why the assumption that biological robots have no feelings?

Then all of your students, past and present were/are extremely fortunate to have you as their professor, with your intellect, you could have done just about anything, worked for any corporation, but you chose to teach. The U.S. educational system definitely needs 10,000 more of you! We need to work on that little cloning problem!!

By the way, light sarcasm is not the same as blatant mocking. Ah, 42 new students will come my way in three weeks. 42 new students to teach that we are not mere accidents climbing out of some primordial ooze. 42 new students to question the "facts" of evolution with. 42 new students to examine the complexity of creation with and ask how it could have all happened by "accident". In that fact...you lose! So let's practice all the jobs you are helping your students get later in life: "Welcome to WalMart" "Do you want fried with that?" "Attention K-Mart Shoppers!" There, did I miss anything. I think your Master's is from an incredibly poor school and your presence makes where ever you teach a even worse school. Your students are the losers. I feel sorry for them, but I don't feel sorry for you. You are just plain pathetic.

MichiganGEL wrote: <quoted text> [Aside: I'm looking forward to when the katydids begin their nightly arguments (Katy *did*!... Katy *didn't*!) in our trees... It'll be a few weeks yet. ;-)] To Katydid, Drew Smith, Ted, Darwin's Stepchild, et al., With your expertise in evolutionary (speciationary?) science, I'd like to get your take on a site that I just came across: http://www.toriah.com/wiki/index.php... At least, it seems to be well- referenced in scientific publications. For example, here's a short excerpt from their response to Miller's chromosome #2 fusion argument, to which you (Katy') alluded: Quote: Casey Luskin put it like this: Under Neo-Darwinism, genetic mutation events (including chromosomal aberrations) are generally assumed to be random and unguided. Miller's Cold-Fusion tale becomes more suspicious when one starts to ask harder questions like "how could a natural, unguided chromosomal fusion event get fixed into a population, much less how could it result in viable offspring?" Miller's account must overcome two potential obstacles: In most of our experience, individuals with the randomly-fused chromosome can be normal, but it is very likely that their offspring will ultimately have a genetic disease. A classic example of such is a cause of Down's syndrome. One way around the problem in (1) is to find a mate that also had an identical chromosomal fusion event. But Valentine and Erwin imply that such events would be highly unlikely: "[T]he chance of two identical rare mutant individuals arising in sufficient propinquity to produce offspring seems too small to consider as a significant evolutionary event." (Erwin, D..H., and Valentine, J.W. "'Hopeful monsters,' transposons, and the Metazoan radiation", Proc. Natl. Acad. Sci USA, 81:5482-5483, Sept 1984) In other words, Miller has to explain why a random chromosomal fusion event which, in our experience ultimately results in offspring with genetic diseases, didn’t result in a genetic disease and was thus advantageous enough to get fixed into the entire population of our ancestors. Given the lack of empirical evidence that random chromosomal fusion events are not disadvantageous, perhaps the presence of a chromosomal fusion event is not good evidence for a Neo-Darwinian history for humans. Miller may possibly have found empirical evidence for a chromosomal fusion event. But, our experience with mammalian genetics tells us that such a chromosomal aberration should have resulted in a non-viable mutant, or non-viable offspring. Thus, Neo-Darwinism has a hard time explaining why such a random fusion event was somehow advantageous. If it were to somehow turn out that the fusion of two chromosomes can only result in a viable individual if the fusion event takes place in a highly unlikely and highly specified manner, then we may actually be looking at a case for a non-Darwinian intelligent design event in the history of the human genus. End Quote First glance it looks like a Torah version of Conservapedia. As for the Casey Luskin article, you do know who he is? A Lawyer for the Discovery Institute, those bastions of Intelligent Design. So anything he says should be couched in the fact that he is not a scientist and he is not impartial in any way. I do disagree with his specific comment because he is following the party line about mutations. <quoted text>"In other words, Miller has to explain why a random chromosomal fusion event which, in our experience ultimately results in offspring with genetic diseases, didn’t result in a genetic disease and was thus advantageous enough to get fixed into the entire population of our ancestors." I love his line "in our experience" What experience is he talking about? He has none and the DI has none in actually working and performing experiments. Luskin is nothing more than a party-line parrot.

Ask any 5th grader when dinosaurs became extinct and they will tell you without batting an eye that it happened 65 million years ago. The FACT of the matter is that they have been indoctrinated into believing in that "fact" by media and educational sources. The TRUTH of the matter is that it could have happened as recently as 2000 years ago or as long as 60 google years ago. There is no evidence of evolution or 65 million year ago dinosaur extinction, but kids are being brainwashed to believe there is. One more time, for those who just don't get it...why are these "facts" which are really just poor theories given the place of an idol in the media and education and scientific worlds? What the hell is a "google years". So the evidence is meaningless. Your posts have convinced me that you have no science education regardless of your claims to having a Master's. Your are a lawsuit waiting to happen.

I'm not a meteorology freak but I've read that hurricanes originate from the activities of Saharan dust storms in Africa and migrate generally towards the Caribbean. It has been suggested that human sailing or ice-floe hoping migration to the Americas could have occurred this way, too, resulting in the indigenous races of South America. And the Clovis Point suggestion of the Solutrean hypothesis may have occurred and those peoples may have died out leaving only few artifacts. They made a point, I guess.:) So, instead of fighting between Leif Erickson, Christopher Columbus, Viking interlopers, Bering Straits newcomers, etc., etc., the answer could be answer K: All of The Above. Hurricanes are named after women because they come in all wet and wild and when they leave they take your house and car

Darwins Stepchild wrote: <quoted text> The NOVA episode on the Clovis Point talked about the hypothesis that Europeans reached North America bringing the Clovis Point with them. This is indeed an intriguing idea, but NOVA did point out that the evidence is quite tentative. For one thing, there are differences between the European spear point and the Clovis point. They are similar, but not exact. As for the gene mentioned, the hypothesis does provide one possible explanation. However, there are other possibilities. For one, it is possible the gene was present in other populations, including one in Siberia, which migrated to North America. Since that time, genetic drift has eliminated the gene in all populations except the population in Europe and the one in North America. A major flaw in the hypothesis is that there is no known way for the Europeans of that time to have reached North America. Even the archeologists that proposed the hypothesis agree that the evidence for it, as of now, is slim. Europeans would not have to reach North America, only the points. Hawaiians were familiar with metal tools before contact due to drifting objects with nails. Some Homer Simpson type hunter could have been crossing a river on his raft and been swept to sea

Now I have to deal with more day-to-day BS and many more distractions so there doesn't seem to be the time to get to a really good level of concentration. When I was 20, I could go for 3-4 hours straight thinking about the same thing without being interrupted. That just doesn't happen now.
