Heisenberg+A3

Heisenberg came up with the Uncertainty Principal that says that determining the position and momentum of a particle necessarily contains errors the product of which cannot be less than the quantum constant h. These errors are negligible in general but become critical when studying the very small such as the atom. This means when trying to find position and velocity of a particle at the same time the results are uncertain. He stated that the act of observation interfered with the location and velocity of small particles such as electrons. When light bounces off an electron momentum exchange can occur between light and the electron which means the electrons location and velocity have been altered by the act of measurement. Therefore electrons don’t travel in neat orbits. He set the foundation to quantum mechanics. He was awarded the Nobel peace prize in 1932 for his contribution to physics.
