Veritasium traces analog computers from the Antikythera mechanism and Kelvin's tide-predicting machines to fire control and modern analog approaches. It explains how these machines computed continuously rather than digitally.

Mick West analyzes the Navy's Gimbal UFO video and gives four checkable observations suggesting it is an infrared glare that appears to rotate because the camera rotates while tracking. He argues the object is likely a hot craft hidden behind the glare.

Techmoan's beginner introduction to the compact cassette, testing metal tapes and Dolby S noise reduction on a Sony TC-S1 deck. He checks whether a cassette can sound close to a CD when good tape and equipment are used.
