The 8-Bit Guy covers IBM's 1981 CGA graphics system, including how composite output and artifacting produced extra colors beyond the nominal palette. He argues CGA looked better in period than it does on RGB monitors.

A hip-hop music video from EconStories in which Keynes and Hayek rap-battle over how to handle recessions and government spending. It is the second round after the first rap battle.

MedCram's Dr. Roger Seheult summarizes a discussion with Dr. Michael Mina on cheap, paper-based at-home COVID-19 antigen tests. It explains why lower sensitivity can still work well for screening infectious people.

Quanta Magazine explains the 2022 experiment that claimed to create a holographic wormhole on Google's quantum computer. The description now notes that a later independent analysis questioned whether any wormhole was created.

Veritasium explains why a halved grape in a microwave makes plasma: the grape traps microwaves, and the fields of two halves interact to concentrate energy where they touch.

National Geographic footage showing the cordyceps fungus infecting ants and other insects and steering their behavior so it can reproduce.

Veritasium explains Bayes' theorem with examples and introduces the 'Bayesian trap', where repeated events get mistaken for inevitable ones. It discusses how priors shape our expectations and behavior.

FortNine explains the economics of the dealership model, arguing that dealers absorb inventory risk and help manufacturers' finances. It looks at whether cars and motorcycles could be sold more cheaply without them.

A short explainer on the history and mechanics of public key cryptography and the Diffie-Hellman key exchange. It uses a mixing-paint-colors analogy to show how two parties can agree on a shared secret in public.

A short demo reel of the 1985 Silicon Graphics IRIS 2400 workstation animating flat-shaded polygons on a 68010 CPU. It shows the early SGI graphics that preceded their later fame.

Seeker's Focal Point short documentary on ASML's extreme ultraviolet lithography machines, which make the most advanced chips. It shows how plasma-generated 13.5 nm light is used to push Moore's Law forward.

A seven-minute demo from the author of Notcurses, a C library for text user interfaces. It shows the 2.3.0 release, which adds Sixel and Kitty bitmap graphics integrated into its multiplane character-graphics model.

3Blue1Brown illustrates how enormous the 256-bit search space is, showing how infeasible it is to find a hash or key by guessing and checking.

Inigo Quilez shows step by step how to build a simple heart shape from mathematics and shaders, with code on Shadertoy. It is an introduction to procedural graphics and signed distance functions.

A Kurzgesagt animation on South Korea's record-low fertility rate and rapidly aging population. It explains why a demographic collapse looks hard to reverse and projects the population shrinking sharply by 2060.

Euclideon's 2011 technology preview of Unlimited Detail, a rendering approach claiming unlimited geometric detail in real time via point-cloud style data. The company promised more to come while keeping most work secret.
