Actually I wrote:
*** begin ***
m = E / c^2 * sqrt(1-v^2/c^2)
So for fixed energy, the mass goes to zero as speed approaches the speed
of light. [smile] (Just kidding on that last statement.)
*** end ***
Look at message comcast.com> and
read it again. I didn't mean for the statement to be true, just a
joke for the benefit of those that reach similar stupid conclusions
as that statement. The odd thing is that the statement is true, just
baseless, since the energy can not be fixed as v changes. Change the
v and you change E. So assuming that you have the same E for all v is
ridiculous.

Relativistic mass is obsolete. We no longer teach it.
