A restored HD upload of the 1983 BBC series Fun to Imagine, in which Richard Feynman talks informally about everyday science. Topics include jiggling atoms, fire, rubber bands, magnets, electricity, mirrors, seeing, big numbers and ways of thinking.

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.

Part two of EEVblog's visit to the NASA/CSIRO Canberra Deep Space Communication Complex, showing the control room and how operators contact Voyager 2. It includes live data and spectrum displays.

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 long Machine Learning Street Talk interview with Kenneth Stanley, creator of NEAT and novelty search, about his book on why greatness cannot be planned. They discuss open-endedness, the tyranny of objectives, serendipity and the evolution of ideas.

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.

A short clip of Richard Feynman answering an interviewer's question about why magnets repel, explaining that a 'why' question depends on a shared framework of understanding. It illustrates how hard it is to explain fundamentals to a layperson.

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.

All six episodes of the 1983 BBC series Fun to Imagine, in which Richard Feynman muses on jiggling atoms, fire, rubber bands, magnets, electricity and more. He explains how to think about nature and why imagination is fun.

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.

A ten-minute clip of Richard Feynman describing how mathematicians and physicists differ in their interests and customs. He argues physics rests on visualizing and applying math rather than pure abstraction.

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.

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.

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.

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.

A short excerpt from a 1973 Yorkshire TV film in which Richard Feynman explains that knowing the name of something is not the same as knowing it.

EEVblog interviews Richard Stephenson of NASA's Canberra Deep Space Communications Complex about how the 70m DSS-43 dish is used to contact Voyager 2. It covers the ground antenna and low-noise receiver side of deep space communication. This is a 2023 re-release of a 2017 video.

A short TFiR clip in which Linus Torvalds explains his view that respect should be earned rather than given, in defense of his blunt and insulting style.

An excerpt from the 1983 BBC series Fun to Imagine in which Richard Feynman describes how he and a mathematician friend counted in their heads in different ways, one verbally and one visually. It shows that people can reach the same goal through quite different mental methods.

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.

Linus Torvalds is interviewed at Aalto University in 2012, followed by an audience Q&A. He talks about Linux, kernel development and the desktop, and about Nvidia support. The Q&A has a well-known moment where he is blunt about Nvidia.
