And another thing...

The GAMS4

Making sure: One hundred years after Albert Einstein published his Special Theory of Relativity, the National Institute of Standards and Technology has helped prove, yet again, that Einstein's most famous equation is correct. NIST, the Massachusetts Institute of Technology and the Institute Laue Langevin of France have completed the most exact test yet to show that E does, in fact, equal mc2. As reported in the Dec. 22 issue of Nature, researchers compared measurements by NIST and ILL of the energy emitted by silicon and sulfur atoms with measurements by MIT of the mass of those atoms. They found that E, or energy, differed from mc2, the mass times the speed of light squared, by at most four tenths of 1 part in 1 million. Close enough, or, as scientists put it, 'consistent with equality.' To measure the atoms' energy, researchers used GAMS4, an instrument designed and built at NIST and now residing at ILL, where the tests were conducted. According to NIST, GAMS4 'measured the angle at which gamma rays are diffracted by two identical crystals made of atoms separated by a known distance.' The truth of E=mc2 had been tested before, but this measurement is deemed 55 times more accurate than past attempts. It may seem academic, but the equation is essential to such things as the Global Positioning System. The more proof, the better. It also adds to wonder over what Einstein managed to come up with without computers, networks or a calculator. Heck, he didn't even blog about it so the real geniuses of the world could post mightily about what an idiot he was.
