eldude 29-Aug-06, 16:57	RANDOM SCIENCE STUFF!!! I am now going to say a bunch of random science stuff. Feel free to put some in yourself
eldude 29-Aug-06, 16:58	You blink over 10,000,000 times a year.
eldude 29-Aug-06, 16:59	Everytime you lick a stamp, you gain 1/10 of a calorie.
eldude 29-Aug-06, 17:01	A pin tip of a nuetron star material wieghs more than 2 of the worlds biggest supertankers. (largest ship)
eldude 29-Aug-06, 17:09	There are more than 50 trillion cells in a human body and more than 5 million red blood cells in a droplet of blood.
saintinsanity 29-Aug-06, 17:37	I've always found this interesting When you stand next to a bonfire you can feel the heat emanating from it. But if you move several feet away you can't feel the heat. So if you try to think about the heat you can feel coming from the sun it sort of boggles the mind.
eldude 29-Aug-06, 17:38	hmmmm intresting. Never heard anything of that kind.
kementari 29-Aug-06, 22:23	nice one pawnt And nice thread, too. I was thinking of something cute and short, but I think I'd rather stay true to form and go with the incredibly long. I'll beg a concession from GK, as some things really are worth the bandwith. This is one of them. It describes a photo taken from the Voyager just before it left our solar system and the scientists that were in charge of snapping photos from it were laid off (budget cuts, you understand.) It was considered by some to be a frivolous endeavor, and almost didn't happen; but what came out of the last minute decision to take this once in a lifetime shot was a picture of our planet, suspended in a beam of sunlight, unthinkably small. This is how Sagan describes it: "Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there-- on a mote of dust suspended in a sunbeam. The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. "Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves." "The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand." "It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known." And that's a fact.
eldude 29-Aug-06, 22:37	nice one kem I've never really know much about the voyagers. And you say the voyager went out of our solar system? Did get destroyed? O, and which Voyager? There are 2 of them.
kementari 30-Aug-06, 08:16	Thank you.

Demon-Haunted World is the one that I would recommend for you, but I'll put out a cautionary note that if your family is religious, this is going to be an extremely challenging read for you.

eldude 30-Aug-06, 11:08	I got a cool science encyclopedia
kingofpawns 30-Aug-06, 13:16	Women... who are close friends or live together synchronize their menstrual cycles... True or False?
eldude 30-Aug-06, 13:18	False?
mozz 30-Aug-06, 14:35	Wrong Exteremely true. An ex girlfriend of mine has three daughters from 14 to 19. There were time when it was downright dangerous to be in their house. My brother also has three teenage daughters. He spends a week a month hiding in his shed. Does anyone know why this happens. I don't have enough time to do the research.
kingofpawns 30-Aug-06, 16:55	eldude... you are correct, it is False, though almost everyone believes that it does occur. Martha McClintock published a paper in the journal Nature in 1971 reporting that women who are close friends or live together synchronize their menstrual cycles. And several other papers were published after that reporting synchrony. However, several clever people came along over the years and pointed out that cycles that are not the same length can never synchronize and that the wrong scientific analyses were applied to the data. Now, the evidence is pointing to the conclusion that women do not synchronize their cycles (and neither do rats  ). There will be some interesting papers on this topic coming out in the journal Human Nature this fall.
eldude 30-Aug-06, 17:08	uh.... I just guessed
kementari 30-Aug-06, 17:54	Interesting, kop And also totally contradictory to my own (albeit anecdotal) experience. I'll look for those articles. I have to wonder if psychology plays a role in this, as my sister freaks out about being pregnant every time we spend a lot of time together. That sounds all wrong, but I'm just going to leave it as is for amusement value.
mozz 30-Aug-06, 18:02	kem You leave so much unsaid, I'm not sure haw many different ways I canlook at that statement in the wrong way.
saintinsanity 30-Aug-06, 18:12	I was under the impression that women do indeed undergo a synchronization of menstrual cycles after living together for a while, due to certain hormones and pheremones and whatnot. When one woman begins her period she gives off these hormones that trigger the other women. But I don't remember where I heard that first, and now I am willing to look at evidence to the contrary. Perhaps its just a coincidence. Although I also remember reading something about "the red tent" in the olden days, when all the women in a village would have their periods on the same cycle and they would spend that time in a tent with the other women, and they didn't have to work. Your hair, fingernails, and toenails keep growing for a while after you die. I also heard that your nose keeps growing too, but that is less believable. Also, they say you lose a bit of weight when you die, but I have never seen conclusive evidence about that and I doubt it.
kementari 30-Aug-06, 19:47	mozz Heh. I'm a big fan of the imagination, and I find it works best when it's slightly warped.
zorroloco 30-Aug-06, 21:14	supernova Astronomers say they have witnessed a stellar explosion - or supernova - unfolding in real time. they say it is 400 million light years away. (that is 20,000,000,000,000,000,000,000 miles or 3,862,400,000,000,000,000,000 kilometers). pretty cool stuff.... news.bbc.co.uk" target="_blank">-> news.bbc.co.uk
mozz 30-Aug-06, 21:23	Well that means that it's all over and done with. Happened 400 million years ago. Wonder what is there now?
kingofpawns 30-Aug-06, 23:45	pawntificator... You are correct that the proposed explanation for menstrual synchrony is pheromones. The main article on which that claim is based was also published in Nature published by Stern and McClintock (1998). There is also an article in that upcoming issue of Human Nature that debunks human pheromones that synchronize cycles. Why do women believe they become synchronized? It is a simple property of rhythms that are not running on the same period. I'll illustrate this with a figure: --------*---------*---------*---------*---------*---------* (period 9) --*-----------*-----------*-----------*-----------*-----------* (period 11) If "*" is a cycle onset date, notice that when the rhythms are not the same period, they repeatedly converge and diverge. There is an interesting discussion on the web: " target="_blank" rel="nofollow" class=ext>www.moltx.org" target="_blank">-> www.moltx.org
saintinsanity 31-Aug-06, 02:09	I find that web site to be rather skewed to one side, but I am willing to consider the points. There was a lot of opinion on that site but I didn't see any research. I found the discussion about the odds to be misleading, and did nothing to dissuade my suspicion that there is some chemical interdependence at work. I bet very few people have performed this sort of inquiry with a scientific approach and I would be interested to see the results.
qiwi 31-Aug-06, 02:32	female synchronicity... Why do they all go to powder their noses at the same time?? What the hell is that all about...?
mozz 31-Aug-06, 02:54	Simple kiwi They want to compare the pathetic males they are with.
kementari 31-Aug-06, 10:08	1/2 right Either that or they're discussing opportunities to upgrade based on the available jean pool...
eldude 31-Aug-06, 11:15	If a flea was the size of a human, it could jump as high as the empire state building.
anomalocaris 31-Aug-06, 13:14	something to think about could we travel faster than the speed of light, say for instance instantly get 50 light years from earth, and look back with a powerful telescope. it would be like looking back in time. if aliens are say 65 million light years away from us maybe they think there are only dinosaurs here. just a thought.
mozz 31-Aug-06, 14:31	kem You mentioned jean pool as opposed to gene pool. Can I assume by that that you are referring as to how well a man fills his jeans? Oh, I feel so violated!
