A 1937 GM-produced film explaining how the automobile differential lets wheels turn at different speeds around a corner. It uses clear animations and cutaway demonstrations to build the idea from first principles.

A Climate Town video on how the auto industry reshaped American cities and culture through advertising, lobbying and campaigns like the 1939 World's Fair. It is snarky in tone but backed by a published source document.

The Lock Picking Lawyer tests the supposedly unpickable lock designs built by the Stuff Made Here channel. He looks for bypasses and weaknesses in the novel anti-picking mechanisms.

Engineer Stuff Made Here builds two new supposedly unpickable locks with different designs and sends them to the Lock Picking Lawyer to see whether they can be defeated. The video covers the novel anti-picking mechanisms.

The trailer for Tim Hunkin's series The Secret Life of Components, eight guides to mechanical and electromechanical parts for designers and makers.

Technology Connections spends 22 minutes on the humble can opener and what its design shows about products and why people don't know what to look for. It uses an everyday tool to draw broader lessons.

Tom Scott explains for Computerphile why handling time and timezones in code is so hard, walking through a simple web app that computes how long ago something happened. It covers the quirks of timezones and calendars and ends in an exasperated rant.

Veritasium explains quantum entanglement and spooky action at a distance, walking through Bell's inequality and the experiments that rule out hidden variables, in under ten minutes.

Not Just Bikes argues that the Netherlands, famed for cycling, is also the best country for drivers. It explains how prioritizing walking, cycling and transit makes driving faster and more pleasant.

Martin Gorner's Devoxx talk introduces deep learning with TensorFlow, walking through neural networks for MNIST, how to choose an architecture and how to diagnose networks that fail to train.

Brian Will follows up his earlier anti-OOP video by walking through four short code examples, including Java code in the style of Uncle Bob, to show how object-oriented design complicates simple programs. It argues that OOP hides and scatters state and adds needless indirection.

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.
