A short side-by-side recording by Jake Archibald of the same animation demo running in Chrome, Firefox, Safari and Servo WebRender nightlies on a 60Hz display. It shows the smoothness difference of GPU-based rendering.

A Capella Science parody of Camila Cabello's Havana, retold as a song about molecular machines and nanotechnology. It features animations of rotaxanes, catenanes and molecular switches, and comes with footnotes.

A two-minute 1981 interview clip in which Richard Feynman answers an artist friend who claims science takes the beauty out of a flower. Feynman argues that understanding adds to beauty and mystery.

A 1953 US Navy training film explaining the basic mechanisms in mechanical fire control computers aboard ships. It shows how gears, differentials and cams solved mathematical problems in permanent mechanical form.

A 1953 US Navy training film on the basic mechanisms in fire control computers: shafts, gears, cams and differentials. It shows how these mechanical parts compute ship and target firing solutions.

A DEF CON 26 talk by investigative journalists and hackers on the fake science industry, with bogus conferences and predatory journals that give studies false credibility. It draws on a large investigation into the money behind them.

Jon Stewart appears as a guest on CNN's Crossfire in 2004 and criticizes hosts Tucker Carlson and Paul Begala for turning political debate into partisan theater that hurts America.

Neuroscientist Anil Seth gives a Royal Institution lecture on the science of consciousness. He separates conscious level, content and self, and argues that experience arises from the brain's predictive inference.

The introductory lecture of Richard Hamming's capstone course, The Art of Doing Science and Engineering: Learning to Learn. It focuses on style of thinking and on educating rather than training, using technical material only as illustration.

A Royal Institution event with Sean Carroll and Jennifer Ouellette on what happens if you fall into a black hole, covering the firewall paradox, the information problem and the holographic principle.
