In 1926, German scientist Heisenberg became famous for his uncertainty principle. The idea is that there is inherent uncertainty to all particles’ positions, and particles can act like waves, with a wider possible area of location. The impact of this discovery led to Heisenberg’s creation of quantum mechanics with Erwin Schrödinger and Paul Dirac in the 1920s.
