An excerpt from Russell Barkley's lecture on ADHD, focusing on inhibition, impulsivity and emotional regulation. It explains ADHD as a problem of response inhibition and emotional impulsivity.

Ten minutes of ultra-slow-motion footage of bullet impacts filmed at about one million frames per second by Werner Mehl of Kurzzeit. It includes hollow points in ballistics gel and impacts on glass.

Scott Manley uses a realistically scaled Kerbal Space Program setup to show why dropping something into the Sun is far harder than it sounds. It demonstrates the need to cancel orbital velocity.

An animation presenting a non-standard helical or vortex model of the solar system, in which the planets trail the Sun through space instead of orbiting in flat circles. The model is a non-conventional view that the author says differs from standard diagrams.

A very short demo of SmackBook, a hack that used the MacBook Pro's sudden motion sensor so that smacking the sides of the laptop switches desktop spaces.

A short National Geographic piece showing a laser system that tracks and kills mosquitoes, filmed in slow motion, as part of anti-malaria efforts. It comes from Intellectual Ventures' 2010 work.

A short Harris Corporation (L3Harris) promotional video showing wide-area airborne motion imagery, a sensor system for persistent real-time aerial surveillance of large areas.

Smarter Every Day uses high-speed and Schlieren photography to show how a whip crack is a supersonic shockwave formed at the tip. It references academic papers on whip physics.

The Slow Mo Guys film a TV and screens with a high-speed camera to show how displays build an image. The footage includes CRT-style scanning and how pixels light up over time.

A CNN segment showing William Shatner emotionally describing his Blue Origin suborbital flight to Jeff Bezos right after landing.

A two-minute Insider Tech clip on DeepMind's simulated agents that learned to walk, run, jump and climb without guidance, with the goofy resulting gaits.

An animated Gabbard diagram of objects in low Earth orbit from 1959 to 2021, showing altitude over time. It highlights major debris-generating events and how low-altitude debris decays out of orbit.

SpaceX's own compilation of failed orbital booster landing attempts, set to sound, showing the crashes before landings succeeded.

Captain Disillusion explains the visual effects behind the Back to the Future trilogy. He covers ILM's motion-control, computer-controlled camera work and clever pre-CGI tricks.

David Sachs of InvenSense explains how gyroscopes, accelerometers and compasses work on their own and together, demonstrated on a modified Android handset. He covers sensor fusion algorithms and why rotation math such as Euler angles matters.

Robert Sapolsky's Stanford lecture on the limbic system as the emotional part of the nervous system, covering its role in decision making, links to the cortex and the functions of its subparts.

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.

Google ATAP's short 2014 introduction to Project Tango, a mobile device effort to give phones and tablets a human-scale understanding of space and motion. It pitches ideas like indoor navigation and games that interact with your physical space.

An old lab video of a decerebrate cat walking on a treadmill and shifting between gait patterns as the speed changes. It is used to illustrate that much locomotion control comes from the spinal cord and body mechanics rather than the brain.

Dr. Russell Barkley gives a nearly three-hour lecture of essential ideas about ADHD for parents, covering what ADHD is, its effects on executive function, motivation and emotion, and how it affects children.

Chris Toomey of thoughtbot explains Vim as a language of commands, motions and text objects that combine into precise edits. He shows how to master the built-in pieces and extend them.

Smarter Every Day films Prince Rupert's drops, tempered glass drops, in high-speed slow motion at 130,000 fps. It shows how the drop's heavy internal stress lets the head survive hits while the tail shatters the whole thing.

Captain Disillusion's VFXcool episode, led by Alan Melikdjanian, takes a 41-minute nostalgic look at how the visual effects of Flight of the Navigator were made. It covers early computers, motion control, in-camera effects and practical crafts.

Animator Noodle explains why frame interpolation does not make animation better, covering timing, easing, smear frames and using the wrong tool for the job. A pinned correction says the video is partly outdated given later AI developments.

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.

Mark Rober shows an automatic bullseye dartboard that tracks a thrown dart with motion capture and moves in real time so it always hits the center. He spent over three years on the project.

Dan Britt lectures on the history of climate, covering orbital cycles, ice ages and conditions millions of years ago. It frames current climate debate with deep-time context.

Scott Manley examines why SpaceX, Google and others are looking at orbital data centers. He walks through the economics, heat rejection and solar power arguments, with links to the Lumen/Starcloud and Google Suncatcher papers.

Scott Manley analyzes the idea of putting data centers in orbit, prompted by Lumen Orbit's funding. He examines the claimed advantage of constant solar power against launch cost, cooling and mass.
