The Uncertainty Principle
Werner Heisenberg to Einstein, Copenhagen, 10 June 1927, facsimile
Heisenberg defends himself against Einstein's attacks on the uncertainty principle. Even if one assumes that the
good Lordknows the location of particles more precisely than the uncertainty principle allows, this does not alter the fact that the result of experiments in quantum mechanics cannot be deterministically predicted. However, it is
not right to use physics to describe more than the context of the experiments.
