It seems to me that to discover a new phenomenon revolutionary enough to the world of physics/chemistry/what have you so that the unit in which its measured is named after you is one of the highest honors. However, as far as I'm aware, that stopped happening after the early days of quantum physics in the 20s and 30s, and we've just discovered all the measurements. Am I wrong? Was there a discovery in the 90s of a unit measured in Johnsons?
