Albert Einstein’s

Albert Einstein’s works in 1905 shock the world of physics. In his explanation of the photoelectric effect, he introduced the photon theory of light.
In his paper “On the Electrodynamics of Moving Bodies,” he introduced the concepts of special relativity.
Einstein spent the rest of his life and career dealing with the consequences of these concepts, both by developing general relativity and by questioning the field of quantum physics on the principle that it was “spooky action at a distance.
