3Blue1Brown shows how the uncertainty principle arises from Fourier transforms. A wave packet cannot be narrow in both position and frequency, so the principle is a property of waves rather than of measurement.

David Spiegelhalter, Professor of the Public Understanding of Risk, uses statistics to weigh everyday risks such as bacon sandwiches and cycling. The six-minute piece introduces micromorts as a way to compare the risk of dying.

The original music video for Everybody's Free to Wear Sunscreen, a spoken-word piece built on Mary Schmich's 1997 column of life advice, produced by Baz Luhrmann.

A hobbyist build-and-experiment video on rotating detonation engines (RDEs), where a continuous detonation wave spins around an annular chamber. The creator 3D prints parts and tests a small engine, while being candid about uncertainty over whether a true rotating wave was achieved.
