One of the fundamental equations of the theory of relativity, To²=Tr²+Et², probably even one of the most beautiful in all of science,

Hachel failed to define his terms, so that's neither fundamental nor
beautiful.

A problem will appear to emerge in the development of uniformly accelerated frames of reference, because if we set x=(1/2.a.Tr²+Vr.Tr)
it no longer works.

If the first equation is relativistic, the second surely is not.
