A Brief History of Time

by

Stephen Hawking

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.
