Heisenberg’s uncertainty principle illustrated with a position–momentum probability cloud, Δx Δp ≥ ħ/2 equation, and a worried Werner Heisenberg cartoon.

⚛️ What does the uncertainty principle say?

Artur Pachota

Heisenberg’s uncertainty principle is often misunderstood as a limitation of measurement. In reality, it reveals something deeper: position and momentum cannot both be defined with unlimited precision because uncertainty is...
