Arthur Keller gives a roughly half-hour crash course on environmental collapse, covering exponential growth, carrying capacity and ecological overshoot.

A half-hour television special on the 2007 fiery collapse of a connector in the Bay Area's MacArthur Maze and its rebuilding in 26 days. It was produced for the Professional Engineers in California Government.

Arthur Ganson's kinetic sculpture chains twelve 1:50 worm gear reductions so the final gear, embedded in concrete, would take over two trillion years to turn once.

An animated clip from the second radio series of The Hitchhiker's Guide to the Galaxy in which Arthur Dent argues with the Nutrimatic drinks dispenser, which produces something almost, but not quite, entirely unlike tea.

An Isaac Arthur episode on civilizations in the far future, past the Black Hole Era. It covers iron stars, Boltzmann brains, reversible computing and the idea of reversing entropy.

Isaac Arthur surveys the popular proposed solutions to the Fermi Paradox in a 71-minute compendium. He weighs the strengths and weaknesses of each argument.

Isaac Arthur explains the orbital ring, a megastructure launch-assist system that could move bulk cargo cheaply to orbit and beyond. He compares it with space elevators and discusses power transmission.

An Isaac Arthur episode on civilizations in the dark, post-stellar universe, including black hole farming, accretion disks and the Penrose process as energy sources.

Isaac Arthur's in-depth look at what it would take to settle and eventually terraform Mars. He covers the challenges and the scale of the work needed to make it a home for humanity.

An Isaac Arthur episode on arcologies, self-sufficient habitats that could house whole cities, on Earth or on harsh worlds. It covers how such structures might work and what limits their size.

Isaac Arthur examines the Dyson Dilemma, the puzzle of why we see no Dyson spheres or megastructures if growth-oriented civilizations should build them. He covers detectability and whether such structures could hide.

Isaac Arthur explains the Matrioshka Brain, a hypothetical computer or artificial mind powered by an entire star using nested shells. It covers how such megastructures relate to Dyson spheres and superintelligence.

A very short clip from the children's cartoon Arthur riffing on the line about not believing everything you read on the internet.

Isaac Arthur examines the Dark Forest theory, Cixin Liu's proposed solution to the Fermi Paradox in which civilizations stay silent and may destroy any that reveal themselves. He tests the theory's underlying assumptions and arguments.

Isaac Arthur explores space-based solar power, in which satellites beam energy down via microwaves to rectennas on Earth. He discusses feasibility, profitability and its role in spurring space colonization.

Isaac Arthur examines options for colonizing Venus, from vast floating habitats in the temperate upper atmosphere to full terraforming of the planet. It is a long-form speculative futurism episode in his solar system colonization series.

Isaac Arthur examines Dyson spheres and swarms, including common myths and misconceptions. He covers uses such as interstellar travel, black hole generation, and computing large enough to simulate universes.

Robert Smith of Rigetti Computing talks at a Bay Area Lisp and Scheme meetup about using Common Lisp for quantum computing. He covers the technical, sociological and psychological sides of working across disciplines.

Ahmon Dancy of Franz Inc explains low-level programming in Common Lisp, including off-heap data structures used in AllegroGraph to manage memory outside the garbage collector.

A 1987 talk in which John Backus, creator of Fortran, presents function-level programming and the FL language, a successor to his FP work. It is an archival recording with links to the related paper.

A Dyalog demonstration of developing a Sudoku solver in APL, using an algorithm by Arthur Whitney with performance work by John Scholes. The narration steps through the array-oriented solution.

The BBC TV version of the Babel Fish passage from The Hitchhiker's Guide to the Galaxy, with Ford and Arthur aboard a Vogon ship, narrated over the show's hand-drawn animated Guide entry.

Harvard professor Arthur Brooks explains why boredom is useful rather than something to avoid. He describes how a wandering mind engages the brain's default mode network, which supports creativity and curiosity, and suggests it may protect against depression.

A scene from the BBC's Hitchhiker's Guide to the Galaxy TV series in which Arthur argues vegetarianism in a restaurant where the dish of the day cheerfully offers up parts of its own body.
