Walter White, the lead character in the incredibly successful Breaking Bad TV series, calls himself Heisenberg. He names his meth-making alter ego Heisenberg after the famous Heisenberg Uncertainty Principle.
What is the Heisenberg Uncertainty Principle?
Werner Heisenberg's principle is concerned with subatomic particles, which are almost completely invisible to us. Complete invisibility is, of course, what Walter White would like to achieve as a meth 'cook.'
The show's creator, Vince Gilligan said: “Thank you so much for this wonderful farewell, you have been very kind to us indeed."
