He describes languages converging, with ideas such as STM and LINQ moving between them.

Veritasium explains why clickbait titles and thumbnails work, how he tests them, and why educational creators feel pushed to use them. He classifies types of clickbait and discusses the trade-offs.

Veritasium explains why bicycles are stable, arguing that gyroscopic effects are not the answer. The video shows countersteering and an experiment where riders blocked from steering the opposite way cannot turn.

Carl Sagan's December 1985 testimony to Congress on the greenhouse effect, about 15 minutes long. He lays out CO2 warming, the risk of runaway effects and the danger of continued coal burning.

An 11-minute clip of Milton Friedman explaining the incentives of unions and how they affect employment. He argues unions restrict labor supply, raising pay for some workers while hurting low-skill workers.

Andrew, diagnosed with early onset Parkinson's at 35, shows how deep brain stimulation surgery has controlled his motor symptoms. The short video shows his tremors with the stimulator off and on.

Moral philosopher James Flynn explains the Flynn effect, the steady rise of IQ scores across the 20th century. He argues the shift reflects a move toward abstract, hypothetical thinking as cognitively demanding professions grew.

Veritasium examines research suggesting science explainer videos like Khan Academy's make students feel they understand while tests show they have not learned, because misconceptions go unaddressed. It suggests how to partly fix this.

The first part of a ShaderToy live-coding series that lays the groundwork for The Drive Home, a rainy night-traffic shader. It covers basic setup and builds toward rain and bokeh effects.

PBS Space Time examines Roger Penrose's idea that consciousness arises from quantum processes in the brain, and reviews new evidence about microtubules. It ends with an estimate of what replicating consciousness would demand.

Veritasium explains the Dzhanibekov effect, also called the tennis racket theorem, where a spinning object flips unexpectedly about its intermediate axis. The video gives an intuitive account of the underlying rotational dynamics, drawing on Terry Tao's explanation and the original papers.

The first-place PC demo at Assembly 1992, Unreal by Future Crew, showing real-time effects such as palette-based wormholes.

Ben Heck modifies a keyboard with magnets, Hall effect sensors and an Xbox controller so the WASD keys give analog control. He walks through the hardware build.

A through-the-lens comparison of the Oculus Quest 2, HP Reverb G2 and Valve Index, capturing what each headset's display actually looks like. It also previews a 90Hz mode coming to Quest 2.

Dave Jones of EEVblog demonstrates that a frequency counter can detect gravity through the 2g tipover effect on quartz crystal oscillators. He shows the reading shift as the instrument's orientation changes.

Folding Ideas uses the rise and fall of the YouTube competitor VidMe to examine why platforms are not friends to creators. It argues that alternatives to big platforms tend to attract the users banned from the original and lack a core vision.

Captain Disillusion debunks a viral Chinese invisibility cloak video while parodying popular educational channels. Along the way he explains chroma keying and green screen techniques.

Captain Disillusion's comedic, fast-paced explainer on how color works in cameras, displays and video. It covers the biology of color perception and what it means for screens.

RocketJump Film School argues that we only notice bad CG while great CG is invisible, so CG seems to be everywhere ruining movies when it often is not.

The official music video for Kylie Minogue's Come Into My World, directed by Michel Gondry, built around a looping scene with multiplying copies of Kylie.

Footage of FAA altitude chamber hypoxia training for pilots in which a participant passes out from oxygen deprivation. It shows how quickly and subtly cognition fails at altitude.

PBS Space Time argues that the speed of light is better understood as the speed of causality, the universal limit on how fast cause and effect propagate. Light travels at that speed because it is massless, but the limit itself is a property of spacetime.
