The history of the stopwatch
Link here. The most fascinating part of this story is the recent discovery of the very first stopwatch, previously unknown, built in 1816, and remarkably similar to the standard analog stopwatches used for decades until the arrival of digital equipment.
The layout of the compteur also makes one suspect it ended up in 1816 via a time machine. Instead of inking paper, it has a silvered and frosted metal dial dominated by a large fraction-second hand like later stopwatches, and three subdials for marking hours, minutes, and whole seconds Along with this, the stopwatch has a button at 12 o’clock to start and stop it, plus an 11 o’clock button to instantly reset the dials. This is a feature common to modern stopwatches and one not thought to be invented until 1862 by Adolphe Nicole.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Imagine the tooling required back then that created this time piece, the different materials required to make a mechanical watch operate, the skills required to craft and fashion these parts that must be near perfect to operate in some semblance of harmony, boggles the mind.
