Primitive Technology shows building a cord drill from scratch and then upgrading it to a pump drill, using only primitive materials like a stone flywheel and cord.

Not Just Bikes explains how North American speed limits are set and why posted limits matter far less than street design. It argues that drivers follow the road's cues, so safe speeds have to be built into the street.

A tour of the historic WLW transmitter facility in Mason, Ohio, recorded at Hamvention 2013. It shows the surviving equipment from the 500,000 watt AM era, when WLW was the only US station at that power, and explains the history.

A short video of railroad workers in Storfors, Sweden, using thermite to weld rail sections together.

A video debunking popular primitive-building YouTube channels, arguing that their digging, concrete and construction are staged. It uses the Primitive Technology channel as a baseline for what is plausible in a natural setting.

The first lecture of an MIT course on Douglas Hofstadter's Godel, Escher, Bach, covering themes like self-reference, recursion and incompleteness. The full lecture series is on YouTube.

A documentary on the 1972 Club of Rome study Limits to Growth, which questioned the pursuit of endless economic growth. It covers the study's findings and whether anyone acted on them.

A short Harvard animation narrated by Professor Rob Lue introducing mitochondria as the cell's powerhouses and how cells turn food and oxygen into energy.

Patrick Winston's long-running MIT lecture on public speaking teaches heuristic rules for talks. It covers how to start, use time and place, boards, props and slides, and how to inform, persuade and finish.

The first lecture of MIT's 6.001 (SICP) with Abelson and Sussman, giving an overview of the course and an introduction to Lisp. It argues that computer science is about managing complexity and abstraction, not computers.

First session of MIT 15.401 Finance Theory I (Fall 2008) taught by Andrew Lo, giving a course overview and introducing core finance concepts. The course ran during the 2007-08 financial crisis.

Erik Demaine's MIT 6.006 lecture introducing dynamic programming through Fibonacci numbers and shortest paths. It covers memoization, subproblems and optimal substructure.

The first lecture of Michael Sipser's MIT 18.404J Theory of Computation course, covering course mechanics, finite automata, regular languages and regular expressions. It proves closure of regular languages under union and begins concatenation.

MIT 22.01 lecture by Michael Short explaining the Chernobyl accident technically, including RBMK reactor positive feedback, xenon poisoning and the cascade of human errors during the test.

Lecture 7A from MIT 6.001 (SICP) by Abelson and Sussman introduces the metacircular evaluator, a Scheme interpreter written in Scheme. It shows how evaluating a program is itself a program.

Zach Hartwig of MIT introduces the key concepts of magnetic fusion energy and the state of fusion research. He then presents MIT's proposed pathway of using high-field superconducting magnets to build smaller, cheaper tokamaks on a climate-relevant timescale.

David Mitchell's Soapbox rant on employers who demand passion and enthusiasm from workers, using satire to skewer fake workplace passion.

A Primitive Technology episode in which the creator builds a bow-drill-driven bark fan to blow air into a fire, using only natural materials. It shows the progression from fanning a fire by hand to a rotary forge blower.

The Primitive Technology channel shows the making of a stone axe (celt) using only primitive tools and materials, from shaping and polishing a basalt head to making the wooden handle and hafting it.

A 1992 MIT Sloan talk and Q&A by Steve Jobs, then CEO of NeXT, covering NeXT's strategy, co-creating Apple, his ouster, and the value of direct experience. It ranges across technology, business and career advice.

A three-minute David Mitchell's Soapbox rant addressed to Americans about the phrase "could care less", arguing it means the opposite of what speakers intend. Delivered as dry British comic commentary on language usage.

Jon Moore's Strange Loop 2017 talk argues that rate limiting is the wrong tool for protecting services from noisy clients. He proposes concurrency-based capacity management and quotas instead.

In Top Gear's second part, racing driver Sabine Schmitz tries to lap the Nurburgring in a Ford Transit van in under ten minutes. She finishes just over the mark.

Noam Chomsky's 2011 University of Oslo lecture on Newton's contributions to the study of mind. He argues Newton abandoned mechanical explanation and lowered the bar for scientific intelligibility, with consequences for the limits of human understanding. Q&A starts at 45:33.
