May 4, 2011rin(romania)When uranium atoms split the neutrons clashing eachother release the energy to make the atomic bomb, but how come so much energy from such a small piece of uranium?This is a perfect example of Einstein's equation E = mc2. Although the excess mass m of the un-split uranium is small, the factor c is so large that the energy release E is also large. The physical reason is that uranium is less stable than what it splits into.
March 26, 2010veronica (philippines)who was the first scientist?Some people consider Galileo Galilei to be the first scientist because his spectacular work in the sixteenth century, but Roger Beacon already advocated experimentation in the thirteenth century (one of Bacon's books, Perspectiva (Optics) includes several experiments with all the steps of the scientific method). Yet other people consider Ibn al-Haytham (born in Basra, in what is now Iraq) in 965, to be the first scientist. He wrote more than 200 books and treatises on a wide range of subjects. He was the first person to apply algebra to geometry, founding the branch mathematics known as analytic geometry.

March 4, 2009Nathalie (philipines)how did the scientists measure the earth?Eratosthenes was a Greek astronomer in ancient times. Around 240 B.C. he made the first good measurement of the size of the Earth. Eratosthenes used the lengths of shadows to figure out how high in the sky the Sun was in a certain place on a certain day. He knew of another place where there was no shadow at all on the same day. That meant the Sun was straight overhead. He found out the distance between the two places, then used some geometry to figure out the rest. The full explanation of his method can be found in our web page Eratosthenes' Calculation of Earth's Circumference.

September 3, 2008noreen (india)about isac newtonIsaac Newton was an English scientist and mathematician who lived between 1642-1727. He had one of the most brilliant minds the world has ever known. Legend has it that seeing an apple fall gave Newton the idea that gravity, the force which keeps us bound to the Earth, also controls the motion of planets and stars. Newton's contributions to science include the universal law of gravitation, the development of a whole new field in mathematics called calculus, and his famous three laws of motion.
August 19, 2008Ronald (worcester,Ma)Is it really true that the end of the world is going to be on December 21,2012 and will there be any chance that you scientists could destroy that asteroid? Or safe the earth from this horrible thing ? Please try to safe earth. and are there going to be life on earth or will there be a place to stay until the air clears out? or can you guys tell us exactly where the comet is going to land? is there any chance that you guys can save like a couple of people? and please choose me first and my family please.This article should answer your question. Ask your parents to read it and discuss it with you. Anyway, let me quote the last three paragraphs: "But scholars doubt the ancient Maya extrapolated great meaning from anticipating the alignment — if they were even aware of what the configuration would be. Astronomers generally agree that "it would be impossible the Maya themselves would have known that," says Susan Milbrath, a Maya archaeoastronomer and a curator at the Florida Museum of Natural History. What's more, she says, "we have no record or knowledge that they would think the world would come to an end at that point." University of Florida anthropologist Susan Gillespie says the 2012 phenomenon comes "from media and from other people making use of the Maya past to fulfill agendas that are really their own."
June 19, 2008jaywhy schrodinger performed a experiment using cat?In the middle of wide discussions about quantum mechanics, Schrödinger proposed the example of a living entity to illustrate how bizarre it was. This was not a real experiment. This is what Schrödinger wrote: "One can even set up quite ridiculous cases. A cat is penned up in a steel chamber, along with the following device (which must be secured against direct interference by the cat): in a Geiger counter there is a tiny bit of radioactive substance, so small, that perhaps in the course of the hour one of the atoms decays, but also, with equal probability, perhaps none; if it happens, the counter tube discharges and through a relay releases a hammer which shatters a small flask of hydrocyanic acid. If one has left this entire system to itself for an hour, one would say that the cat still lives if meanwhile no atom has decayed. The psi-function of the entire system would express this by having in it the living and dead cat (pardon the expression) mixed or smeared out in equal parts. It is typical of these cases that an indeterminacy originally restricted to the atomic domain becomes transformed into macroscopic indeterminacy, which can then be resolved by direct observation. That prevents us from so naively accepting as valid a "blurred model" for representing reality. In itself it would not embody anything unclear or contradictory. There is a difference between a shaky or out-of-focus photograph and a snapshot of clouds and fog banks."
March 14, 2008francis what is the 1543 cannon that made the light dawn in the center?It was Copernicus who figured out that the Sun was in the center of the solar system (light dawned in the center) and not the Earth.

April 13, 2007Elizabeth (Utha)Who is Johannes Kepler? What did he do?Johannes Kepler's primary contributions to astronomy/astrophysics were his three laws of planetary motion, derived by studying the observations of the Danish astronomer Tycho Brahe.
February 8, 2007Hayden (Canada)what is the solar system theory of Hipparchus?Hipparchus was a Greek astronomer who lived between 190-120 B.C. He created the first accurate star map and kept a catalogue of over 850 stars with their relative brightnesses. He also developed the system of epicycles (where everything in space moved in perfect circles) for the planets that both agreed with observation, and preserved the Earth-centered universe of Aristotle. Perhaps the discovery for which Hipparchus is most famous is the discovery of precession which is due to the slow change in direction of the axis of rotation of the earth. Abundant information about this Greek astronomer can be found at our web page Hipparchus, and in this detail biography.

May 25, 1999Carmen (Australia)What are sedimentary rocks used for?Sedimentary rocks can be used for a number of things. Sedimentary rocks form layers or stratifications. Each layer is layed down during a certain time period, so sedimentary rocks can be used to tell the geological record of an area. Scientists can tell when an organism lived through which layers its fossils are in. It's almost like looking back in time, pretty neat. Sedimentary rocks can also be quite beautiful. Take a look at this picture .
May 12, 1999Codi(Oregon,USA)why isnt there gravity on other planets? Is there life on the other planets besides earth? Are you a real scientist and whats you name? Are you famous? Have you been on any other planet before? How old are you? Are you telling me the truth?Boy oh boy, you sure have a lot of questions! All planets have gravity. Some planets have more than others. Right now, we know that only Earth has life, although we are always look ing for others. Yes, I am a real scientist!(Although I just joined the Windows team recently) No, I'm not famous.... YET. I haven't been on any other planet- that I know of. I'm a lot older than you.... And of course I'm telling you the truth! Scientists don't lie!
