Lieutenant General Mark Hertling gives a TEDx talk arguing that obesity and poor youth fitness are a national security problem because too few young Americans can meet military physical requirements.

A short clip of Richard Feynman on the difference between merely knowing how to reason mathematically and understanding why physical theories work. He discusses holding multiple equivalent ideas and guessing new laws.

Computerphile interview with Prof. Ross Anderson on how Chip and PIN payment systems are being compromised, and the attacks researchers have seen.

A critique of the HD remaster of Buffy the Vampire Slayer, walking through cropping, color and effects problems that damaged the original look. It also advises which versions to buy.

LockPickingLawyer examines a challenge involving a tamper-sealed Abus lock and shows how the tamper seal can be defeated.

A ten-minute clip of Richard Feynman describing how mathematicians and physicists differ in their interests and customs. He argues physics rests on visualizing and applying math rather than pure abstraction.

A clip of Richard Feynman contrasting the Greek and Babylonian traditions of mathematical reasoning. It compares the axiomatic approach of mathematicians with how physicists use mathematics.

CGP Grey's video "Humans Need Not Apply" argues that automation will make a large part of the workforce economically obsolete, much as engines did for horses. It surveys robots and software replacing both physical and mental labor.

Tom Scott explains why electronic voting is a bad idea. Elections must be trusted by everyone and attacks on software scale in ways attacks on paper do not, so open source or blockchain fixes do not solve it.

A 1936 Chevrolet-sponsored film that explains how a car transmission works by treating gears as spinning levers. It uses physical models to make the mechanism clear.

Veritasium explains the effort to redefine the kilogram, which was still defined by a physical artifact, and how a near-perfect silicon sphere from the Avogadro project helps. It also covers the history of the unit's odd naming.

AngeTheGreat describes building a physically realistic internal combustion engine simulator in C++, drawing on fluid dynamics, physics and chemistry. It generates procedural audio for engines such as a V8.

Veritasium shows silicone oil droplets bouncing on a vibrating bath, a physical analogue of pilot wave theory that reproduces quantum-like behavior such as double-slit patterns.

Veritasium explains why the kilogram is being redefined in terms of Planck's constant rather than a physical metal artifact. It visits NIST to show the Kibble balance and why measuring mass precisely is hard.

An Every Frame a Painting video essay analysing how Edgar Wright creates visual comedy through framing, camera movement, editing, sound effects and music.

PBS Space Time introduces Miguel Alcubierre's warp drive, explaining how spacetime itself could be warped rather than moving a ship through it, and whether it is physically possible.

A 1983 behind-the-scenes film about making the HBO 'Feature Presentation' starship logo sequence. It shows the handcrafted miniature city, motion-control cameras and practical effects.

CGP Grey explains the elegant ratio of A4 and the metric paper sizes, then zooms out across scales from the Planck length to the observable universe.

A BBC Earth clip from The Hunt showing Portia jumping spiders, which leap many times their body length and ambush prey larger than themselves.

An episode of Coding Secrets by Jon Burton on retro copy protection, in particular physically damaging a disk with a laser so copies fail. It explains how this defeated hackers and pirates.

Matt Parker of Stand-up Maths demonstrates MENACE, Donald Michie's 1961 machine made of matchboxes that learns to play noughts and crosses through reinforcement. He builds and trains a physical version.

A 12-minute demo of the Alternate Reality Kit, built by Randall Smith at Xerox PARC in 1986. It is a simulated physical world in which users manipulate objects and program by direct interaction.

Grace Hopper appears on Letterman and uses a foot-long piece of wire to show how far light travels in a nanosecond.

Nigel Stanford's music video Cymatics, in which real science experiments, such as Chladni plates, ferrofluid and water, visualize the audio.

TechAltar's history of Philips, once Europe's largest tech company and a world leader in lighting, radio and physical media. It traces how the company sold off or spun out its businesses, until little remains but the licensed name.

Scott Galloway's DLD15 talk assessing the competitive positions of Amazon, Apple, Facebook and Google. He argues about where each is strong and weak, including Amazon's need for physical retail.

Keiichi Matsuda's short concept film depicting a future where physical and virtual realities have merged and the city is saturated with media and advertising. It shows an augmented-reality-filled daily life as a provocative vision.

Pranav Mistry demos SixthSense, a wearable device that projects information onto the physical world and lets people interact with data through gestures. He also shows a paper "laptop" and says he will open-source the software.

Steve Jobs's January 2007 MacWorld keynote segment introducing the original iPhone. He presents it as a widescreen iPod, a phone and an internet communicator in one device.

A Seeker short documentary on a lab where robots run experiments with almost no human intervention, covering automation and active machine learning in drug discovery and synthetic biology.

Footage of a protest at the University of Toronto against a talk by Warren Farrell on men's issues, including protesters blocking attendees from entering. It is part of a series of videos on similar campus protests.

Thunderf00t's second video critiquing SpinLaunch, the company that proposes flinging rockets and payloads into space with a giant centrifuge. He argues the idea is physically unworkable.
