Well, changing the second changes the newton, pascal, joule, watt, hertz, becquerel, gray, sievert, katal, weber, henry, tesla, coulomb, volt, farad, ohm, siemens, and the units of velocity and acceleration. Oh, and the meter would have to be redefined.
Is it really worth changing all of science to divide an ever-changing length of day into decimal morsels? The metric system is not a disconnected, ragtag band of units where you change one willy-nilly without affecting everything. And you would still have leap-seconds because the length of the day is not fixed. ________________________________ From: "[email protected]" <[email protected]> To: U.S. Metric Association <[email protected]> Sent: Fri, July 8, 2011 6:50:48 PM Subject: [USMA:50847] Re: Stretching the second I am sorry are you referring to 9192631770cycles of radiation corresponding to the transition between two energy levels of the caesium-133 atom?

Id put my money on the sun and solar energy. What a source of power! I hope we dont have to wait til oil and coal run out before we tackle that.
