... Photoelectric effect In 1839 it was observed that when visible or uv light is aimed at a clean metal surface, electrons are ejected from the metal, causing an electrical current. Unexpectedly, a light energy threshold was required before electrons would be emitted. In 1905, Albert Einstein applied ...

Depending on a measurement of position or momentum on system one, due to the reduction of the wave packet both momentum and position of system two could become an element of reality by their definition. But since the operators for momentum and position do not commut ...
