Ron Garret's Google Tech Talk argues that quantum mechanics is no harder to understand than relativity and that popular accounts wrongly rely on the Copenhagen interpretation. He presents measurement as entanglement and explains phenomena like the quantum eraser.

Technology Connections takes apart a 1940s Sunbeam Radiant Control toaster. It senses the toast's own browning and lowers and raises it automatically using purely mechanical parts and no electronics.

Allan Savory's TED talk arguing that desertification of grasslands can be reversed with holistic managed grazing, which he says would also help reverse climate change. TED notes that other scientists have challenged his claims.

A short explainer on the history and mechanics of public key cryptography and the Diffie-Hellman key exchange. It uses a mixing-paint-colors analogy to show how two parties can agree on a shared secret in public.

The first of four short videos from Bill Hammack (engineerguy) introducing and giving the history of a 100-year-old mechanical computer, Michelson's harmonic analyzer. The series goes on to explain Fourier synthesis, analysis and operation of the machine.

A 2007 Channel 4 documentary by Martin Durkin arguing that human-caused global warming is overstated or a scam. It features contrarian scientists such as Richard Lindzen and promotes sunspot and cosmic-ray explanations for temperature change. Its claims are rejected by mainstream climate science.

An animated visualization of basic quantum mechanics using a free particle, with simulations based on the actual equations. It covers waves, particles, and how measurement collapses the wavefunction.
