jan 1, 1927 - Werner Heisenberg
Description:
-1901 - 1976, Bavaria Germany
-In 1927 he was puzzling over the basic quantum properties of electrons. He realized that the act of measuring an electron's properties by hitting it with gamma rays would alter the electron's behavior. Indeed, you could measure the position of an electron (or other particle) OR you could measure its momentum. But the more precisely you measure one property, the more you throw the other off.
-He considered trying to measure the position of an electron with a gamma ray microscope. The high-energy photon used to illuminate the electron would give it a kick, changing its momentum in an uncertain way. A higher resolution microscope would require higher energy light, giving an even bigger kick to the electron. The more precisely one tried to measure the position, the more uncertain the momentum would become, and vice versa
