Physicist Angela Collier's roughly hour-long video on how string theory was hyped to the public and what that did to science communication. She traces the history of the theory as a narrative and argues it is interesting but was oversold.

Alan Kay argues for rethinking how computer science is taught in schools, drawing on his work on object-oriented programming and GUIs. He discusses how poorly people understand complex systems and what education could do about it.

Dan Callahan presents Mozilla Persona, a decentralized, cross-browser authentication system that removes site passwords, at PyCon 2013. He explains how the protocol works and how to add it to a Python site.

A short Inside Edition segment on Daniel Kish, a blind man who uses tongue clicks as human sonar to ride a bicycle through city traffic. He explains that he hears the reflections of the sounds off objects.

Salman Khan explains why he created Khan Academy, a structured library of video lessons with interactive exercises. He calls on teachers to flip the classroom, with lectures watched at home and homework done in class with teacher help.

A detailed 40-minute explanation of the ultraviolet catastrophe, covering Rayleigh and Jeans' classical treatment of blackbody radiation and Planck's quantum hypothesis. It follows the Eisberg and Resnick textbook treatment.

Nicholas Zakas of Yahoo discusses architecture for large, modular JavaScript web applications. He lays out the theory behind building front ends that scale in complexity.

A one-minute clip from a cat cafe in Japan where sleeping cats wake and look around just before an earthquake begins shaking the room.

Ed Catmull of Pixar speaks at Stanford's 2007 Entrepreneurship Conference on running a creative company. He argues for surfacing small problems early and building good teams, with stories like the Toy Story 2 crunch.

Christopher Domas's Derbycon 2015 talk on the M/o/Vfuscator, a compiler that emits only x86 mov instructions, showing mov is Turing complete. It explains how a full machine is built from mov and why the output is a nightmare to reverse engineer.

An Extra Credits episode on China's Sesame Credit, which gamifies obedient citizenship through a social score. It covers how the system rewards conformity and pressures people through their friends' behavior.

Bill Hammack of engineerguy explains how medieval engineers designed stone cathedrals using rules of thumb, with no science, mathematics or literacy. He uses it to define the engineering method.

Moxie Marlinspike's DEF CON 19 talk on the weaknesses of SSL and the certificate authority system. He explains how CA trust became a problem and proposes an alternative that removes the CA oligopoly without reducing security.

Organist Hans-Andre Stamm performs Bach's Toccata and Fugue in D minor, BWV 565, on the Trost organ in Waltershausen, Germany, an instrument from 1730. The video shows the playing and footwork.

Kedi is a feature documentary following seven street cats of Istanbul and the people who care for them. It portrays the relationship between the city and its cats.

Cory Doctorow's DEF CON 31 talk describes how platforms decay in a pattern he calls enshittification. He lays out a plan to stop it through antitrust, interoperability and fixing the law.

CGP Grey explains jury nullification, a juror's power to acquit despite the law, and why mentioning it can get you struck from jury selection.

Bach's Toccata and Fugue in D minor on organ, shown with a Music Animation Machine bar-graph score instead of traditional notation.

Matt Parker of Stand-up Maths examines scatter plots that were claimed to show fraudulent vote-switching in Michigan's 2020 election. He recreates the analysis and shows that the pattern arises from comparing percentages across different bases, not from fraud.
