Alfred Kastler quotes

Alfred Kastler was a French physicist who made significant contributions to the study of atomic physics and quantum mechanics. His research on optical methods to study atomic states laid the groundwork for important advances in laser technology. He received the Nobel Prize in Physics for his groundbreaking work on the interaction of light with atoms. Here are 2 of his quotes:

I must confess that, at that time, I had absolutely no knowledge of the slowness of the relaxation processes in the ground state, processes which take place in collisions with the wall or with the molecules of a foreign gas.
