Ben Krasnow of Applied Science shows how to make and test YBCO high-temperature superconductor with a kiln and eBay chemicals. He demonstrates flux pinning and shows a close-up of the crystal structure.

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 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.

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.

Clifford Stoll's energetic TED talk, a wandering mix of anecdotes, a science experiment and thoughts on curiosity, education and technology. He is the author of The Cuckoo's Egg.
