There has been much research published lately that describes, in detail, an explosion that wiped out North America 12,900 years ago. But where did it happen? The answer is that the site of the Pleistocene/Holocene comet impact event some have described has been right under our feet all along. But the stupendous size of the thing is almost beyond comprehension. And that is why we never realized what we were standing on. And until we saw Shoemaker-Levy 9 hit Jupiter, it would have been incomprehensible that such a thing could possibly happen at all. The story of finding it is a lot like the ancient story of the blind men and the elephant. The blind man who feels a leg…

Montreal in the Quebec province of Canada is located at a latitude of 45°30′N and currently shows a temperature of -28°C. http://www.weather.com/outlook/travel/businesstraveler/local/CAXX0301?from=enhsearch_loc In Zurich (Switzerland) which is even in a slightly higher latitude than Montreal (47°22′N) it's only 2°C. http://www.weather.com/outlook/travel/businesstraveler/local/SZXX0033?from=enhsearch_loc I wonder why is Montreal so cold for it's latitude?

MOMA design curator Paola Antonelli previews the groundbreaking show "Design and the Elastic Mind" -- full of products and designs that reflect the way we think now...(...about science and design.)

Hello all, This is my first post here. I would need several hard-to-find information for my project and would be grateful to anyone that could point me to the direction of papers that could contain such information or provide those info directly. First, speaking about long-established science fields like mythematics, chemistry, sociology, etc. (or their subdisciplines), what is the approximate quantity of knowledge information currently reached in those fields (in bits or bytes)? Second, how big is the quantity of information that an expert in a specific field has stored in his/her brain? Of course, to be an expert, you must know crucial information an…

We consider much of what science has to offer and time travel is the proverbal boomerang that keeps coming back , the time machine may well have been a great work of fiction , that has no doubt inspired a generation of scientists to postulate over the possibility of eventually travelling through time. This new dimension concept or fifth dimension and multiple dimensions is a new born brainchild and a ever increasing subject of obvious popularity. We can brush the ethics aside because we know that human nature dictates otherwise , not entering into the ethical debate or the obvious dangers and chaos that would eventually ensue. Is time travel possible ? can we ex…

Time Travel Sci-Fi or fact, the last thread leads onto this new thread. We eventually escape from earths imminent disaster by travelling back to earth through time . We eradicate our past without us knowing it and the new earth history is written the new world order documents the mistakes of this dimension and we reshape a new dimension is this the fifth dimension. It is hard to imagine a new race of people that learn from one dimension and live within a new world order with time lords . This may well be the survival of the human race . We disappear through time to save humanity and reshape a new dimension the concept is inviting to us . If we indeed explore inf…

Hundred of millions of years ago. when our planet was already formed. The planet was completely covered with water. Oceans were not as deep as they are today, but only a few hundred feet deep but thousand of miles long. As time passed, green sea moss began to grow in the shallow areas. Since there was no sea life, like fishes or other type of sea life, to eat or disturb the moss, it grew very thick. After a while, this moss broke away and slid down in the deepest vallies. As more time passes this moss will be hunded of feet deep and thousands of miles long. The moss at the lower depth start to decompose into a black slimy goo, as more moss come on top,…

I am not sure if this is the appropriate place to post this. I have been into Tesla coiling for 4 years or so now. I just recently revamped my medium sized Telsa coil so it would be much more efficient. I just need to know if anyone here can help me about HV capacitor advice. Here are some pictures of my capacitor. http://s515.photobucket.com/albums/t360/tealman535/Tesla%20Coil/ It the right value and everything I just need to know if anyone here believes that the leads are perhaps too close together. The top and bottom leads are in direct connection with the the HV Transformer. So there is potentially 15kV at the left and right of the capacitor. I hop…

Does anyone know the current temperature on the top of mount Mckinley in Alaska?

Optical disc technology is a topic I never understood. How do the microscopic bumps in the optical disc contain data?

Let me first say that this is not a justification for recent anthropogenic warming. The last 30 years is a bit too much and we should begin remedial measures. However, the reference below is interesting. http://www.sciencedaily.com:80/releases/2008/12/081217190433.htm It suggests that the world would be entering a new glaciation period, with glaciers advancing, and the whole world cooling, if it were not for early anthropogenic global warming. If this is correct, I am glad it happened. I would much rather live in our current relatively balmy conditions than in a new deep freeze.

LA Speaks Draft Master Plan will not work because a river environmental disaster will occur with the plan as proposed A shipping terminal has fallen in the river in the past (1974-75? near Plaquemine, La.) from high velocity water but I am sure the terminal was designed to meet government regulations with respect to piling depth...etc. After this event several diversions were added to the river and this has added piling undercutting capability to the river due to added velocity. Adding more diversions in the future may be the straw that breaks the back and, I believe, more shipping terminals will fall into the river. There should not be any added diversions that incr…

what is the ultimate goal of space exploration.how much part of the earth has been studied.

i have been building a current sensing PWM useing plans that only have one MOSFET but i am wanting touse more fets and my question is to use more than one fet would i just connect all of the gates, drains, and sources? or would i need to hook multiple fets up a different way? oh yeah and also would hooking the fets up that way increase the output?

Hello, recently I was at a party and thier were balloons that were blown up with regular air, not helium, when playing with one I raised the question to my friend that "If there were billions of balloons(with regular air in them) and all these balloons were on top of a person, is it possiable to be crushed to death, I think yes with enough amount of balloons but my friend things not, I know a person would maybe be suffocated but im looking for weather or not a person would be crushed. The answer seems os obviously yes cause a balloon weights something can someone answer this question please with a more detail explination as to why a person would be crushed. Thanks

Can anybody help me identify the specs of these mosfets?... the are on a stereo amp and i want to see if i can use them before i de-solder them sorry for the crappy quality of the pics but the numbers on the front are: K D718A O___OF and the other one is: K B688A O____OF I am just wondering how i can get the specs for them.... thanks for anyhelp

just a quick question, can anyone corroborate that 512 seconds at f512 is the equiv of 1/125 Sec at f8 (assuming that ISO 100 is used for both)?

'science' - as we know it - is constantly changing with the addition of new discoveries. old theories that were once believed to be accurate are becoming obsolete and regarded as quite silly, actually. the world according to science was once flat, modern science has disproved this theory. could it be that with the progression of time our modern scientific beliefs could meet the same fate? this is the pattern that is starting to emerge: what is thought to be modern and accurate scientifically theories are disproved later on in time when a new discovery is made that makes the old theory look ridiculous and unthinkably stupid. in my observation, scientific theories come…

Ten years ago on December 4, 2008, NASA and its partner nations began building a dream: the International Space Station. On that date, space shuttle Endeavour lifted off on its 12-day mission to deliver NASAs Unity module and connect it to Russias Zarya control module already orbiting Earth. Enjoy:-)

With commander Chris Ferguson and pilot Eric Boe at the controls, space shuttle Endeavour descended to a smooth landing at Edwards Air Force Base, Calif. The STS-126 crew members concluded their successful mission to the International Space Station when the shuttle touched down at 4:25 p.m. EST. Enjoy:-)

can anyone help me get some info on this process, I`v read a little bit about it (in a book) and it sounds like something I`d like to try. I`v googled it and it only gives 8 hits and non of them are of any use. I believe it`s related to Lithography somehow, but I lack details. Anyone?

Hey all, Here's one for you English teachers. While it's not exactly science, I couldn't think of a better place to post this. This is probably been asked over and over, but what is the correct way of asking a question to which the answer would be, for example, "He was third", or "I'm fifth in line", or "Five is the third Prime Number". I know one can ask something like "What position does *something* occupy in the sequence of *something*" but isn't there another way? Cheers, Gabe

Refrigerator magnets stick to refrigerator doors (duh, common sense, eh?), so the fridge must have an opposite magnetic charge to a fridge magnet. One is positive, the other is negative. But by that notion, two fridge magnets should both be the same charge, and thus should repel each other, yet they stick to each other. Why is that? EDIT: Btw, I put this in Chemistry because I learned about positive and negative charges in Chemistry class. If this is in the wrong board, please quietly move it to the proper one.

I came across the above heading in a New Scientist article and thought it was worth posting here, since it is thought provoking. Since it is based on yet another global climate model, I am sceptical of its accuracy - but hey - somebody has gotta be right! The story is also found at : http://news.nationalgeographic.com/news/2008/11/081112-ice-age-global-warming.html It suggests that the world's climate is destined in 10,000 to 100,000 years, to go into a massive ice age, lasting tens of millions of years, and more severe than any of the glacial periods over the past million years. However, anthropogenic global warming saves the day! With human released green…

We just had a rather interesting experience. While melting butter on the stove on low heat, the liquid butter essentially exploded, sending hot butter raining all over the kitchen. This doesn't make much sense to me. What exactly would cause something on low heat to gather enough energy to splatter the entire kitchen? (One of our cats immediately decided the floor tasted rather good. That was funny.)
