FrankM Posted May 25, 2007 Report Posted May 25, 2007 (edited) The Consultative Committee for Units (CCU) in its final report for 2005 made the following recommendation, “the consensus that now exists on the desirability of finding ways of defining all of the base units of the SI in terms of fundamental physical constants so that they are universal, permanent and invariant in time”. The second and the meter were not included in this consensus. http://www.iupap.org/commissions/interunion/iu1/u1-2005.pdf There is a better way. http://vip.ocsnet.net/~ancient/InconvenientTruths.pdf There is nothing wrong with defining the speed of light to provide a common reference, but they claimed they improved its accuracy by the 1983 definition. Wouldn't it be better if it was defined by mathematical and physical science constants? Edited August 16, 2010 by CraigD Fixed broken link Quote
