How Humans and Matter Transformed One Another
Elizabeth Ruth Naomi Belville made her living by selling a rather odd commodity. Every week, she’d travel to the Royal Observatory in Greenwich, London. There, she’d set her pocket watch – it was nicknamed “Arnold” and had once belonged to the Duke of Sussex – to Greenwich Mean Time. Once this had been done, she’d visit the dwellings of the people subscribed to her service.
What was that service? Allowing them to set their clocks to Arnold. This is how Belville made her living for almost 50 years, from 1892 until her death in 1940: she sold the time. People called her the Greenwich Time Lady.
The key message here is: Improved timekeeping technology deepened our obsession with time.
Belville was successful because Arnold was accurate – very accurate. Made of the finest materials, Arnold kept the time better than other clocks, even though it’d been made in the eighteenth century. But in the twentieth century, even Arnold’s accuracy was surpassed.
In 1939, a new kind of clock was displayed in the window of a shop on Fulton Street, in Manhattan, New York. Soon enough, hundreds of passersby were using this extremely accurate clock to set their own timepieces.
The clock was so fantastically accurate because it contained a special kind of crystal: quartz. Quartz is special because, when exposed to an electrical current, it begins to vibrate. In 1927, a Canadian scientist named Warren Marrison figured out how to use this quality to improve the precision of clocks. He fashioned a small, thin ring out of quartz. Then, using electrical signals, he caused the ring to vibrate at a steady rate of 100,000 vibrations per second. This mechanism could be used to measure time with stunning precision.
Improved time-keeping methods only served to reinforce certain time-related ideologies. Puritan settlers, who arrived in America in the seventeenth century, strongly believed that time should not be wasted. This view was perpetuated by Benjamin Franklin’s capitalist notion that “time is money.” Throughout the nineteenth century, as the United States industrialized and the factory became the main driver of the economy, timekeeping and time management assumed even greater importance.
Factories relied on clocks to tell workers when to start working and when to stop. It wasn’t long before the rhythm of the factory pervaded all of modern life – dictating when people awoke, when they ate, and when they slept.
This certainly improved productivity. But it’s been argued that this rhythm, which is still with us today, is also at the root of many sleeping disorders.
The Alchemy of Us (2020) offers a history of some of the most important technologies ever developed, from clocks to glass to the steel rails used to make railway tracks. It explains how these technologies were created and explores how they shaped human culture.
As technologies become more pervasive in our lives, whom they were built for and optimized for will be an important discussion.
Ich bin begeistert. Ich liebe Bücher aber durch zwei kleine Kinder komme ich einfach nicht zum Lesen. Und ja, viele Bücher haben viel bla bla und die Quintessenz ist eigentlich ein Bruchteil.
Genau dafür ist Blinkist total genial! Es wird auf das Wesentliche reduziert, die Blinks sind gut verständlich, gut zusammengefasst und auch hörbar! Das ist super. 80 Euro für ein ganzes Jahr klingt viel, aber dafür unbegrenzt Zugriff auf 3000 Bücher. Und dieses Wissen und die Zeitersparnis ist unbezahlbar.
Extrem empfehlenswert. Statt sinnlos im Facebook zu scrollen höre ich jetzt täglich zwischen 3-4 "Bücher". Bei manchen wird schnelle klar, dass der Kauf unnötig ist, da schon das wichtigste zusammen gefasst wurde..bei anderen macht es Lust doch das Buch selbständig zu lesen. Wirklich toll
Einer der besten, bequemsten und sinnvollsten Apps die auf ein Handy gehören. Jeden morgen 15-20 Minuten für die eigene Weiterbildung/Entwicklung oder Wissen.
Viele tolle Bücher, auf deren Kernaussagen reduziert- präzise und ansprechend zusammengefasst. Endlich habe ich das Gefühl, Zeit für Bücher zu finden, für die ich sonst keine Zeit habe.
Hol dir mit Blinkist die besten Erkenntnisse aus mehr als 7.000 Sachbüchern und Podcasts. In 15 Minuten lesen oder anhören!
