FROM THE COLLECTION
explainerA 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.
commentaryNot Just Bikes argues that self-driving cars will worsen sprawl and car dependence and harm cities. The video compares car-centered and people-centered urban design and weighs what cities should do instead.
explainerTechnology Connections explains how dishwashers work, why detergent pods underperform powder, and how to use the pre-wash and main-wash compartments. It argues you don't need to pre-rinse dishes.
documentaryA 1953 US Navy training film explaining the basic mechanisms in mechanical fire control computers aboard ships. It shows how gears, differentials and cams solved mathematical problems in permanent mechanical form.
lectureA re-upload of American Airlines captain Warren Vanderburgh's 1997 presentation warning that pilots who over-rely on cockpit automation lose manual flying skills and awareness. The uploader adds context from his own flying.
explainerTechnology Connections takes apart a 1940s Sunbeam Radiant Control toaster. It senses the toast's own browning and lowers and raises it automatically using purely mechanical parts and no electronics.
![Frame from Stroads are Ugly, Expensive, and Dangerous (and they're everywhere) [ST05]](https://i.ytimg.com/vi/ORzNZUeUHAM/hq2.jpg)
explainerNot Just Bikes introduces the "stroad", a street-road hybrid common in the US and Canada that fails at both jobs. He contrasts it with Dutch design, where each road has a single purpose, and covers cost, danger and ugliness.
tutorialA 1953 US Navy training film on the basic mechanisms in fire control computers: shafts, gears, cams and differentials. It shows how these mechanical parts compute ship and target firing solutions.
explainerBill Hammack of Engineer Guy explains the engineering behind the aluminum beverage can: why it is cylindrical, how it is manufactured, why it narrows at the top, the double seam, and how the pull tab works.
commentaryNot Just Bikes explains why the channel exists, through the creator's walk in suburban Houston. It shows how car-dependent design makes cities hostile to pedestrians.
![Frame from Why American Cities Are Broke - The Growth Ponzi Scheme [ST03]](https://i.ytimg.com/vi/7IsMeKl-Sv0/hq2.jpg)
explainerNot Just Bikes explains the Strong Towns argument that car-dependent American suburbs cost more to maintain than they generate in taxes. It describes the growth Ponzi scheme that props up municipal finances.
talkTim Ewald's Clojure/conj talk uses furniture making with hand tools versus machine tools as an allegory for software. It explores how automation changes what we make and how we think about our work, and why Clojure's small set of simple tools matters.
