Recently a young guy (saying to be engineer) claimed for a revolution on science. It claimed for a basic error on Einstein relativistic theory. All modern physics were wrong, he claimed! We lost a lot of time reasoning with he why was completely wrong and his revolutionary theory was just nothing. I reproduce here just part of his completely wrong “Scientific proof” violating even the most basic and elementary tenets of mathematics:

...

dE=dm•v+m•dv;

then

E=m•v+m•v;

therefore

E=2•m•v.

His conclusion: “Einstein and other scientists are wrong”. Note that mathematics is completely wrong even for 16th-year college. Moreover, you can see that he incorrectly writes E instead of p. His misleading reasoning was that since “space-time” signifies that both space and time are the same “thing” on relativistic theory (of course this is completely false) then “energy-momentum” signifies that energy and momentum are the same “thing” and one can put E instead of p on the formulas!
