replication

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.

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.

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 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 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 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.

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.

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 film about the Erlang language, showing telecom systems built from lightweight processes and demonstrating hot code swapping. It is an edited version of the original Ericsson video.

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.

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.
