CERN discovered that neutrinos can be xtremely faster than light!

No, Einstein did not write "E=MC²" first.

Yes, he did have a heavy hand in appropriating its use for modern physics.

So who do you attribute the first derivation of E=mc2 to?

Seems to be this guy.

He's not the only physicist before Einstein to suggest E=kmc^2 for some k. I think someone proposed that E=(3/8)mc^2 as well.

Einstein derived that E=mc^2 with k=1 specifically, as part of his theory of SR. This is why Eintein is known for the equation, and other people aren't.

An electron is pulled over by the police on the highway.
"Son, can you tell me how fast you were going?"
"Sorry, no. But I can tell you exactly where I was."

Good one!

^This. My dad, who is graduated in physics, once told me that the origin of E=kMC² goes back to the mid 19th century, iirc. However, attributing a value other than 1 for K and sayng E = K=/=1MC² is the same that E=1KMC² is like saying that basketball and football are the same sport because the principle behind both involves a bunch of guys running after a ball trying to put it into a net.
