Quantum uncertainties defeat Laplace’s demon

I recently gave a colloquium at the Department of Applied Mathematics of Hanyang University in Ansan, Korea, in which I tried to introduce the idea of incompatibility of quantum measurements to students that were not all perfectly fluent in quantum theory.

Incompatibility, in the form of uncertainty relations, is available in many flavours: statistical and dynamical, variance-based and entropy-based, state-dependent and state-independent… As I was asked to share the slides, I’m now making them publicly available (click on the cover below):


The mechanical hybris is defeated!
