Summary
Updated 2026-06-21

He proved you can't measure both where something is and where it's going with perfect precision at once — a limit built into reality itself, not the instruments. The uncertainty principle made Werner Heisenberg the physicist who put ambiguity at the foundation of matter, then spent the war years leading Germany's atomic program.

Biography

About

Born 5 December 1901, Heisenberg published his Umdeutung paper in 1925, a full reinterpretation of old quantum theory that he and Max Born and Pascual Jordan elaborated into matrix mechanics the same year. Two years later came the uncertainty principle; five years after that, the 1932 Nobel Prize in Physics. He worked on turbulent flows, ferromagnetism, cosmic rays, subatomic particles, introduced the idea of wave function collapse — and served as a principal scientist in the German nuclear program during World War II. After the war he directed the Kaiser Wilhelm Institute for Physics, soon re…

Werner Heisenberg
said
In general, scientific progress calls for no more than the absorption and elaboration of new ideas — and this is a call most scientists are happy to heed.

Werner Heisenberg
said
The problem of values is nothing but the problem of our acts, goals and morals.

Werner Heisenberg
said
Light and matter are both single entities, and the apparent duality arises in the limitations of our language.

said
Every experiment destroys some of the knowledge of the system which was obtained by previous experiments.

The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa.
