Harvard physicist Eric Mazur explains how he realized his students were memorizing rather than understanding, and how he changed his teaching. He presents peer instruction and data showing improved student performance.

Lawrence Krauss's 2009 talk on the current picture of the universe, how it will end and how it could have come from nothing. It covers the expanding universe, cosmic background radiation and the cosmological constant.

Physicist Angela Collier's nearly three-hour critique of Richard Feynman's public legacy. She examines how his books, written with Ralph Leighton, shaped a mythologized great-man image, and covers his personal behavior.

Tom Scott makes the difference between a million and a billion dollars tangible by using distance on a road trip instead of volume. The drive makes the scale of a billion intuitively felt.

Angela Collier, a physicist, revisits her earlier dark matter video, explaining dark matter as a set of observations rather than a theory and discussing MOND comments.

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.

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.

A roughly three-hour technical livestream Q&A on Helion Energy's fusion approach and the National Ignition Facility. It covers neutron production, shielding, energy recovery, diagnostics and why tokamaks might fare better.
