From: spudnik on 20 Jun 2010 00:10 I can do the math, two, if it's just simple differentiation and algebra (pythagorean theorem), but it is so easy to grasp special relativity, conceptually: all atoms have internal (angular) momenta that are limited by -- or perhaps "at" -- the speed of light. perhaps the worst clue is that lightwaves cannot have a (directed) velocity, but only a speed; however, this is forever obscured by using "rays" of light, which is assumed to be the path of a photon, that was called a particle by herr docktor-professor E. but, how can a massless object have a momentum -- are you going to leave that lump under that carpet? another problem is the typicla pedagogy of SR, where it is "simplified by putting the ray of light onto the x-axis; why, bother? --BP love's Waxman's new [*] cap&trade, and Obama is using the spill to impliment [**] it -- and it's all the fault of Califronictors, who won't develop their own oil, instead! * Waxman's '91 cap&trade was for NOx and SOtwo. ** Organized the CCX as a Senator. http://wlym.com
