electromagnetic suspension

A short CNET demo of Bose's electromagnetic active suspension, which gave a very smooth ride but never reached the market. It shows the system in action.

Veritasium explores how electrical energy actually travels in a circuit, arguing that it flows through electromagnetic fields around the wires rather than through the electrons. It builds a long-cable experiment with Caltech to test when a distant bulb lights.

ElectroBOOM examines whether 5G and other electromagnetic waves can harm people, explaining the EM spectrum and the difference between ionizing and non-ionizing radiation. It includes experiments and measurements in his usual humorous style.

Veritasium argues that electric energy is carried by fields around the wires rather than by electrons moving through them, using a thought experiment with a large circuit.

Short British Pathe newsreel footage of the 1940 collapse of the Tacoma Narrows Bridge as it twisted and swayed in the wind. The only casualty was a dog left in a stalled car.

A PBS clip in which Richard Feynman explains the strange nature of light and electromagnetic radiation. He conveys how little of it we actually see and how radio waves are present everywhere.

Tom Scott and Matt Gray talk at Electromagnetic Field about making Emojli, an emoji-only messenger that began as a joke, how it was built and why they never want to do it again.

A 1971 DEC LAB-8/e (PDP-8/e) minicomputer plays music by inducing noise into a nearby AM radio. The software is Richard Wilson's 1975 Music Compiler running under OS/8.

Oracle Red Bull Racing follows a single front suspension bolt through its life, from sketch and drawing through machining, testing, assembly and racing.

A one-minute demo at the Computer History Museum's IBM 1401 restoration lab, where a program makes the machine's radio-frequency interference play tunes on an AM radio.

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.
