It should be v/c not c/v. To give some relevance to this otherwise pedantic post I'll say that I find it much easier to spot the mistake in the line above than the line below. This is precisely because the line above resembles the way the equation would normally be written in a book or on the blackboard etc. > > they aren't likely to be much enlightened by: > > momentum = rest_mass*velocity*(1-(speed_of_light/velocity)**2)**-0.5 > Oscar
