Heisenberg’s Unsharpness Principle — Misnamed as the Uncertainty Principle
In 1926 Werner Heisenberg developed his now famous uncertainty principle. [The original name used by Heisenberg was the unsharpness principle (Unsharfeprinzip). Later the name was mistranslated and popularized as the uncertainty principle (Unsicherheisrelation), from Elementary Quantum Chemistry, Second Edition by Frank L. Pilar, page 19.] It's a purely mathematical concept. It applies anywhere that there are waveforms. The Unsharpness Principle originates not from Quantum Mechanics, but rather from Classical Wave mechanics.
