Bumi Berkarat: The Image That Started It All - A Kick in the Butt down the Environmentalist Road
http://bumiberkarat.blogspot.com/2010/09/image-that-started-it-all-kick-in-butt.html
Thursday, September 2, 2010. The Image That Started It All - A Kick in the Butt down the Environmentalist Road. That one defining moment. One of my friends once asked her 6-year-old nephew what he wanted to be when he grew up. Enthusiastically, and very, very earnestly, he responded: "A dinosaur! To which my friend dryly responded: "That's right, kid. Go for your dreams! For me and my environmental crusade, it was an image. A poster. It wasn't even a pretty image or a pretty poster. I looked at it and th...

Kelvin, Lord William Thomson (1824-1907) -- from Eric Weisstein's World of Scientific Biography
http://scienceworld.wolfram.com/biography/Kelvin.html
Kelvin, Lord William Thomson (1824-1907). Kelvin argued that the key issue in the interpretation of the Second Law of Thermodynamics was the explanation of irreversible processes. He noted that if entropy always increased, the universe would eventually reach a state of uniform temperature and maximum entropy from which it would not be possible to extract any work. He called this the Heat Death of the Universe. With Rankine. Theory of gradual geological change or Charles Darwin's. To study the properties ...

Spring -- from Eric Weisstein's World of Physics
http://scienceworld.wolfram.com/physics/Spring.html
From a spring displaced a distance x. From its equilibrium point is given by Hooke's law. Is the mass and k. Is the spring constant. This law holds (approximately) as long as x. Remains below the spring's elastic limit. Even when the elastic limit. Is not exceeded, pulling a coil spring far enough to uncoil it results in a much larger spring constant than the spring's coiled value. The differential equation describing the spring's motion is. Which is a simple harmonic oscillator.

Leibniz, Gottfried (1646-1716) -- from Eric Weisstein's World of Scientific Biography
http://scienceworld.wolfram.com/biography/Leibniz.html
Leibniz, Gottfried (1646-1716). German philosopher, physicist, and mathematician whose mechanical studies included forces and weights. He believed in a deterministic universe which followed a pre-established harmony. He extended the work of his mentor Huygens. He was self-taught in mathematics, but nonetheless developed calculus. Although he published his results slightly after Newton. His notation was by far superior (including the integral. Discovering the method of separation of variables. And which L...

Smarandache Hypothesis -- from Eric Weisstein's World of Physics
http://scienceworld.wolfram.com/physics/SmarandacheHypothesis.html
Smarandache (1998) proposed that as a consequence of the Einstein-Podolsky-Rosen paradox. There is no speed limit in the universe. Ie, the speed of light. Is not a maximum at which information can be transmitted) and that arbitrary speeds of information or mass transfer can occur. These assertions fly in the face of both theory and experiment, as they violate both Einstein's special theory of relativity. And lack any experimental support. It is true that modern experiments have.

Eddington, Arthur (1882-1944) -- from Eric Weisstein's World of Scientific Biography
http://scienceworld.wolfram.com/biography/Eddington.html
Eddington, Arthur (1882-1944). English physicist who theoretically investigated stellar interiors. He calculated that the temperature. At the center of the Sun. Would have to be in the millions of degrees Kelvin. And published the mass-luminosity law for stars. In 1924. He also worked out the causes for brightness variations in Cepheid variables. On theoretical grounds, he predicted that Betelgeuse would have an angular diameter as large as 0.051 arc seconds. Eddington also disputed Chandrasekhar's.

Faraday, Michael (1791-1867) -- from Eric Weisstein's World of Scientific Biography
http://scienceworld.wolfram.com/biography/Faraday.html
Faraday, Michael (1791-1867). English bookbinder who became interested in electricity. He obtained an assistantship in Davy's. Lab, then began to conduct his own experiments. He wrote a review article on current views about electricity. In 1821, for which he reproduced Oersted's. Experiment. He was one of the greatest experimenters ever. Because he was self trained, however, he had no grasp of mathematics and could therefore not understand a word of Ampère's. 1839-1855). One of his most important con...
