The big problem with relativity is the almost complete absence of clear 
concepts.
There is no need to talk about transverse mass, longitudinal mass, and 
other such joys.
You do like Hachel, you keep it simple, and, like Hercule Poirot, you turn 
on your neurons.
"Mass is a relativistic invariant".
Mass is what it is, like a postage stamp is a postage stamp.
All the bullshit of the relativists only obscures human knowledge, 
deflects it, and does not take it further.
I will never understand all this madness.
It is not mass that is relative, but speed, THEREFORE the quantity of 
movement, therefore energy.
The notion of rest mass is useless at all, except to make physicists look 
like Laurel and Hardy type comedians.
No need for that to give a beautiful, physical, mathematical, coherent, 
true theory.
Human beings are both idiots and pedants.
