Do you have a reference for this? Einstein introduced the concept in one of his classic 1905 papers. -

I have read that paper. Einstein suggests that the effect might be detectable with "radium salts." As for him not believing it that...

It was discovered by maybe Leo Szilard. Einstein didn't believe it at first and had to be convinced. Albert thought that it would be a...

It only applies to particles with rest mass that are at rest. See below. Yes. The general equation is $$ E^2 = p^2 c^2 + m^2 c^4 $$...

According to E = mc², energy seems to depend on rest mass. But photons have zero rest mass (m₀ = 0), and still carry energy, expressed...

Since E = mc^2, how can photons be massless? If a photon has no mass, then, according to Einstein's formula, its energy is given by E =...
