Part one of a four-part upload of a BBC Horizon documentary featuring Richard Feynman, in which he talks about physics and looking at the world from another point of view.

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.

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 clip from the 1983 BBC series Fun to Imagine in which Richard Feynman explains heat as the jiggling of atoms and how we perceive it as hot and cold.

A one-minute clip from Richard Feynman's 1979 Auckland lecture in which he answers whether you see an object or only its light. It is a short, playful take on perception and on the use of philosophy.

A three-minute clip of Richard Feynman using the rules of chess as an analogy for how science works, discovering rules by observation and sometimes meeting surprises like castling. It touches on incremental progress versus revolutions.

A short clip from the 1983 BBC series Fun to Imagine in which Richard Feynman explains how a train stays on the track. He covers the geometry of tapered wheels that steer the train back toward the center of the rails.

A one-minute clip of Richard Feynman playing bongos with his best friend.

A PBS clip in which Richard Feynman explains the strange nature of light and electromagnetic radiation. He conveys how little of it we actually see and how radio waves are present everywhere.

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.

Richard Feynman, in a clip from the BBC series Fun to Imagine, takes on the puzzle of why mirrors seem to swap left and right but not top and bottom.

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 Symphony of Science music video that auto-tunes samples of Carl Sagan, Richard Feynman, Neil deGrasse Tyson and Bill Nye into a song about the wonder of the universe.

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.

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.

A short clip of Richard Feynman explaining how a train stays on its tracks, through the conical shape of wheels and how it handles curves without differentials.

Doug Zongker's deadpan conference presentation of his famously chicken-filled paper, given at the 2007 AAAS humor session. It satirizes academic talks while showing the pitfalls of bad presentation.

A short clip from Carl Sagan's Cosmos in which he explains how Eratosthenes measured the circumference of the Earth using shadows in two Egyptian cities. It is a clear, visual account of an ancient scientific feat.

A segment from Carl Sagan's original Cosmos explaining the fourth spatial dimension through analogy with a two-dimensional world and shadow projection.

The first lecture of Leonard Susskind's Stanford Continuing Studies course on modern physics, beginning with classical mechanics. It is the start of a six-quarter sequence on the theoretical foundations of physics.

Geoff Cumming uses a simulation to show how wildly the p value varies from one replication to the next because of sampling variability. He argues for estimation and confidence intervals over null hypothesis significance testing.

David Spiegelhalter, Professor of the Public Understanding of Risk, uses statistics to weigh everyday risks such as bacon sandwiches and cycling. The six-minute piece introduces micromorts as a way to compare the risk of dying.

Physicist David Deutsch's TED talk on why science took off, arguing that good explanations are those that are hard to vary. It contrasts scientific explanation with myth.

A short clip of a frog levitating inside a roughly 10 tesla magnetic coil, demonstrating diamagnetism.

A short clip of the Mythbusters demonstrating superheated water in a microwave, which can erupt violently when disturbed.

A one-minute clip of Donald Rumsfeld's 'known knowns, unknown unknowns' remarks at a Pentagon briefing.

David Deutsch's TED talk arguing that humanity's survival depends on solving problems through knowledge growth. He frames people as improbable "chemical scum" capable of understanding distant quasars.
