wave function collapse

The Google I/O 2009 keynote introducing Google Wave, a real-time collaborative communication and document platform. It includes a long live demo and the developer preview announcement.

A short MIT Math Lab video showing millimetric droplets bouncing and walking across a vibrating fluid bath, guided by their own pilot waves. These droplets show diffraction, tunneling and quantized orbits, which were once thought to belong only to quantum systems.

Cleared Defense Department footage of Raytheon's Phaser high-power microwave weapon bringing down drones during a 2013 live-fire demonstration at Fort Sill. Raytheon says it has halved the payload size and is offering the system for operational use.

A short demo of a walking droplet on a vibrating silicone oil bath passing through a double slit and producing interference, a macro-scale analogue of pilot-wave behavior.

A one-minute New Scientist clip showing a Japanese experiment in which drivers on a circular track produce a spontaneous traffic jam that travels backward. It illustrates phantom traffic jams without any obstacle.

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.

Stephen Wolfram gives a 13-minute tour of the Wolfram Language, a symbolic, functional programming language with a built-in knowledgebase. He demos querying large datasets, interactivity and deployment.

A controlled demonstration by Wabash National of a tank trailer collapsing under vacuum, staged at an industry expo. The tank implodes as air is pulled out.

A short clip of the Mythbusters demonstrating superheated water in a microwave, which can erupt violently when disturbed.

A Dyalog demonstration of developing a Sudoku solver in APL, using an algorithm by Arthur Whitney with performance work by John Scholes. The narration steps through the array-oriented solution.

A short demo of the Lenovo ThinkPad X1 Carbon's adaptive keyboard row, which changes its keys based on the user's activity.

Linus Akesson demonstrates the Commodordion, a fully functional 8-bit accordion built around Commodore 64 hardware with bellows made of floppy disks. He performs Scott Joplin's Maple Leaf Rag and tells the story of the build.

A short unscripted demo of writing FizzBuzz in JavaScript with a generator function on a steno keyboard, typos included. It gives a feel for what real coding in stenography looks like.

Excerpts from W. Edwards Deming's Red Bead Experiment, where workers draw beads from a bowl and are judged on red ones that are largely down to chance. It shows how system variation, not individual effort, drives results.

A hobbyist build-and-experiment video on rotating detonation engines (RDEs), where a continuous detonation wave spins around an annular chamber. The creator 3D prints parts and tests a small engine, while being candid about uncertainty over whether a true rotating wave was achieved.

A five-minute demo of the Common Lisp debugger fixing a bug, recompiling a single function, and resuming execution from the failed stack frame. It shows how to avoid re-running long computations.

An IIHS crash test pitting a 1959 Chevrolet Bel Air against a 2009 Malibu in a frontal offset collision for the institute's 50th anniversary. The old car's occupant space collapses while the modern car's protects its driver.

A Harvard lecture demonstration in which five metronomes on a movable board gradually fall into synchronization through coupling. Removing the coupling lets them drift out of step.

A Computer History Museum recording of the final demonstration of the Xerox Star, the early graphical user interface workstation. It is a long demo session that shows the design thinking behind desktop, icons and windows.
