Martin Donald explains the Wave Function Collapse algorithm using Sudoku-like constraint solving and shows how he implemented it with Blender and Godot. It links demos and reference articles.

A Tom Scott guest video by Grady Hillhouse of Practical Engineering on the 1981 Hyatt Regency walkway collapse. A seemingly minor change to the support design led to catastrophic failure, which is why the case is taught as a lesson to check and double-check everything.

An animated visualization of basic quantum mechanics using a free particle, with simulations based on the actual equations. It covers waves, particles, and how measurement collapses the wavefunction.

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.

Practical Engineering explains what a black start is: restarting a power grid after total collapse. It shows why most plants need outside power to start and why rebuilding a synchronized grid is delicate and high-stakes.

Asianometry explains why India, a chip design powerhouse, cannot fabricate chips, tracing the 1980s government attempt to build a national semiconductor champion and how it collapsed. It includes the sabotage at the SCL fab.
