... Thompson measures the electron, and puts forth his "plum pudding" model of the atom - the atom is a slightly positive sphere with small, raisin-like negative electrons inside. 1900 Planck suggests that radiation is quantized. 1905 Einstein proposes a quantum of light (the photon) which behaves like ...

... Two observers in different inertial frames will need different wave functions to describe the same physical system. To make things simple we will consider how it works in one dimension: The first observer uses coordinates (x, t) and a wave function ψ(x, t) while the second uses (x0 , t) and ψ̂(x0 , ...
