Wise guy: tests confirm Einstein’s formula correct
`Scientists at Massachusetts Institute of Technology and the National Institute of Standards and Technology (NIST) will report in tomorrow’s (Dec. 22) issue of the journal Nature that Albert Einstein’s formula, E=mc2, is correct. [..]
By comparing NIST measurements of energy emitted by silicon and sulfur atoms and MIT measurements of the mass of the same atoms, the scientists found that E differs from mc2 by at most 0.0000004, or four-tenths of 1 part in 1 million. The researchers said the result was “consistent with equality” and is 55 times more accurate than the previous best direct test of Einstein’s formula.’
