1 Formula for Brownian Motion This was one of Albert Einstein's first inventions, based on experiments he did while he was in college.2  If you're like most of us and don't know what the Brownian Motion is, it's the movement of particles in liquids.3  No one had documented this effectively until Einstein came along. This was the basis for quantum physics, which Einstein also invented through his experimentation. 2  Formula for Brownian Motion This was one of Albert Einstein's first inventions, based on experiments he did while he was in college.
