A short clip from a Richard Feynman interview in which he explains fire, describing how burning wood releases sunlight stored by the tree, which built itself mostly from air. It showcases his curiosity and plain-spoken explanations.

A 1983 BBC interview in which Richard Feynman is asked how magnets work and explains why 'why' questions are hard to answer in everyday terms. He reflects on what counts as an explanation and the limits of analogy.

A short clip of Richard Feynman answering an interviewer's question about how magnets work, in which he explains why a why-question has no simple answer without a shared frame of reference.

Lex Fridman interviews Harvard astrophysicist Avi Loeb about the interstellar object Oumuamua, aliens and black holes. Loeb lays out his argument that it may be an artifact rather than debris.

A clip from the BBC Fun to Imagine series in which Richard Feynman is asked how magnets work and explains why 'why' questions depend on a shared framework of understanding and cannot always be answered in layman's terms.

Physicist Roger Penrose and philosopher William Lane Craig discuss the origin of the universe on the Unbelievable? show. Topics include Penrose's three realms of reality, conformal cyclic cosmology and whether fine tuning points to a creator.

Sixty Symbols interviews Nottingham cosmologist Tony Padilla, who says string theory deserves to be taken seriously. He explains how strings emerged from the equations rather than being invented.

Freeman Dyson recounts how Enrico Fermi rejected his team's meson scattering model, noting that it had too many free parameters. It is the source of the quote about fitting an elephant.

Fraser Cain interviews JPL physicist Slava Turyshev about using the Sun's gravity as a lens to image distant exoplanets. They cover how the lens works, how a spacecraft would align with it, and mission design.

Physicist Jacob Barandes discusses his view that quantum mechanics can be formulated without wave functions, using a stochastic, probabilistic approach. The long interview covers measurement, the foundations of quantum theory and the history of the field.

A short excerpt from a BBC interview in which Richard Feynman explains why he dislikes honors and prizes, including his own Nobel, saying the real reward is the pleasure of finding things out.

Grace Hopper appears on Letterman and uses a foot-long piece of wire to show how far light travels in a nanosecond.

Brady Haran interviews Brother Guy Consolmagno, director of the Vatican Observatory, for Sixty Symbols. It is part of a three-video set along with the observatory's telescopes and its meteorite collection.

A clip from a BBC interview in which Richard Feynman is asked why magnets repel and attract. He explains that "why" questions depend on what a person already accepts as fundamental.

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.

In Ars Technica's War Stories, Naughty Dog co-founder Andy Gavin explains how the team squeezed Crash Bandicoot onto the original PlayStation. They overwrote Sony library code in RAM, built custom animation compression, and streamed assets around slow seek times.

The full 1971 Dutch television debate between Noam Chomsky and Michel Foucault on human nature, with subtitles. They discuss creativity, knowledge, power and politics.

A two-minute clip of Richard Feynman explaining why he considers much of social science pseudoscience. He stresses how easy it is to fool yourself and how much care real knowledge takes.

Myst co-creator Rand Miller recounts how the HyperCard-built game struggled to run on 1x CD-ROM drives. He and his brother Robyn compressed image and audio data heavily to get acceptable performance. Part of Ars Technica's War Stories series.

Slavoj Zizek and Paul Holdengraber discuss surveillance and whistleblowers at the International Authors' Stage, ranging over Snowden, Assange, Pussy Riot and humor.

Noam Chomsky talks with the University of Washington's Upon Reflection about how languages change over time, why a national language is a modern idea, and how language is a system of communication rooted in human nature.

A five-hour Lex Fridman interview with John Carmack covering Doom, Quake, VR, AGI, programming, games and rockets.

Peter Robinson interviews Peter Thiel at the Hoover Institution about Thiel's essay The Straussian Moment. Thiel discusses how people trust the will more than the intellect and reason, and how the question of human nature has been abandoned.

Daniel Schmachtenberger discusses why the information ecology is damaged and what healthy public sensemaking would take. The conversation ties this to the meaning crisis and to improving discourse.
