The opening lecture of Ian Shapiro's Yale course Power and Politics in Today's World, which examines political dynamics and institutions over the past quarter century, including inequality, declining unions and new forms of authoritarianism.

A short demo of the Deep Visualization Toolbox, which shows the activations inside a convolutional neural network as it processes live camera input. Viewers see individual units responding to edges, faces and text.

Nicholas Zakas of Yahoo discusses architecture for large, modular JavaScript web applications. He lays out the theory behind building front ends that scale in complexity.

A 1956 episode clip of the game show I've Got a Secret in which 95-year-old Samuel J. Seymour appears as the mystery guest. He was the last living eyewitness to Lincoln's assassination at Ford's Theater, and the panel tries to guess his secret.

Christopher Domas presents his Cantor Dust tool at Derbycon 2012, a 3D visual approach to reverse engineering binaries by visualizing their structure dynamically.

John Oliver's Last Week Tonight segment on police interrogation tactics and how they can lead innocent people to give false confessions.

Hans Rosling uses data and animated statistics to show how world population is changing, why birth rates fall as child survival and wealth rise, and why population is expected to peak around 11 billion. It also tackles common misconceptions about Africa and family planning.

A political commentary video arguing that tech billionaires such as Thiel, Musk and Andreessen, along with figures like Yarvin, are using the new administration to push their agenda. It connects Yarvin's ideas with Project 2025.

Astronaut Mike Mullane explains normalisation of deviance, where teams gradually come to accept violations of their own safety standards. He uses the Challenger shuttle disaster as the main case, drawing on NASA's ignored warnings before the launch. It is the first part of a talk given to a fire-fighters' association.

Hans Rosling uses population statistics to explain why the world population will level off rather than grow without limit. He shows that falling child mortality and rising prosperity lead to smaller families.

A short RepresentUs explainer on how money corrupts American politics and what an anti-corruption act could do about it. It covers lobbying, super PACs and campaign finance, and pitches the group's proposed reforms. The video was later superseded by an updated version.

Hans Rosling's TED@Cannes talk uses boxes and animated data graphics to show how world population will grow to about 9 billion. He argues that raising living standards for the poorest is what reduces population growth.

A short clip of George H. W. Bush and Ronald Reagan answering an audience question on illegal immigration at a 1980 Republican primary debate. Both take notably sympathetic positions, including on schooling for undocumented children.

Mathematician Colin Wright demonstrates juggling and explains the mathematics of juggling patterns, including notation that led to new throwing patterns. It is a public presentation at the Museum of Mathematics aimed at a general audience.

Wendover Productions explains how the US military moves people and materiel worldwide, including prepositioned equipment, sealift and airlift. It shows the scale of the logistics system behind US force projection.

A JuliaCon talk by a NASA Launch Services Program engineer on modeling spacecraft separation dynamics in Julia. He describes replacing a Simulink-based workflow for checking launch vehicle separation requirements with Julia and ModelingToolkit, with large speedups and much shorter code.

Big Clive does a complete teardown of a lithium phone battery, taking apart the protection circuit, case and the cell itself. He notes it was risky because the cell was not discharged first.

Robert Moss's JuliaCon 2015 talk describes using Julia as a specification language for ACAS X, the next-generation airborne collision avoidance system that succeeds TCAS.

A short clip of Milton Friedman explaining who benefits from occupational licensing requirements, arguing they mainly protect practitioners from competition.

Researchers from the Artificial Life Lab Graz introduce the Primordial Particle System, where a simple motion law for self-propelled particles produces cell-like structures that self-reproduce and show life cycles.

Greg Kroah-Hartman's Linaro keynote on contributing to the Linux kernel, explaining why maintainers prefer upstreamed code and how they view contributions.

A short Inside Edition segment on Daniel Kish, a blind man who uses tongue clicks as human sonar to ride a bicycle through city traffic. He explains that he hears the reflections of the sounds off objects.

A Bell Labs film in which Dr. J.N. Shive uses a mechanical wave machine to demonstrate reflection, standing waves, resonance and impedance matching. He includes some equations but relies mostly on real-world examples a layperson can follow.

3Blue1Brown visualizes the Riemann zeta function and the analytic continuation that extends it beyond where its series converges, building toward the Riemann hypothesis.

Real Engineering's Brian McManus explains Helion's approach to nuclear fusion: colliding two plasma rings, compressing them magnetically, and capturing energy directly from the changing magnetic flux rather than boiling water. It covers why this pulsed design sidesteps problems of tokamaks and laser fusion.

A demo of the Symbolics Graphics Division's S-Packages, a Lisp-based 3D color graphics and animation system from the 1980s. It was later used in developing for the Nintendo 64.
