skeleton clock

The first episode of Clickspring's series building a John Wilding skeleton clock from raw stock in a home machine shop. It covers making the frames along with the tools needed for the job.

CuriousMarc powers up a vintage HP 5061A cesium beam clock and explains both the quantum principle and the HP implementation in detail. It is part of a longer atomic clock series.

A short clip from an ACM and Computer History Museum interview in which Leslie Lamport discusses writing his paper on time, clocks and the ordering of events. He explains its link to special relativity.

Alexander Rose of the Long Now Foundation describes the design and construction of the 10,000 year clock conceived by Danny Hillis. He covers the project's history, methods, and how different cultures built things to last millennia.

A Technology Connections video essay on how analog and digital clocks shape different mental models of time, with the minute hand acting as a progress indicator.

A Not the Nine O'Clock News sketch that satirizes the controversy around Monty Python's Life of Brian.

The first episode of Clickspring's series on reproducing the Antikythera Mechanism by hand, laying out the plan and the history. The series follows a machinist building the ancient Greek device with traditional tools and methods.

Veritasium explains why the one-way speed of light has never been measured, only the round-trip speed, since measuring it requires synchronized clocks that assume the answer. It explores the implications for relativity.

Tom Scott explains the famous Dutch flower auction clock at Royal FloraHolland in Aalsmeer, a literal Dutch auction, and how the internet changed it. It is a short look at how the system worked then and now.

Historia Civilis traces the history of work and time discipline, comparing modern working hours with those of medieval peasants and the changes brought by clocks and industrialization. It draws on works such as Schor's The Overworked American.

Clickspring makes the pin-and-slot epicyclic gearing of the Antikythera Mechanism, the module modelling the Moon's variable motion in the Greek theory, by hand.

Michael Steil's 33c3 talk explains essentially everything about the Game Boy: CPU, video hardware, peripherals, and the tricks used by games and demos. It revives the era of counting clock cycles around hardware limits.

Overclocker der8auer tours Hetzner's Falkenstein data center in Germany, showing custom racks, own mainboards, passively cooled servers and ATX-style cases on shelves.

Dan Abramov's JSConf Iceland talk on what came after React 16, with live-coded prototypes of async rendering and time slicing. It previews the ideas that became concurrent mode and suspense.
