To celebrate being alive for a billion seconds, Daniel Bruin built a machine with 100 gears with a 10-to-1 gear ratio…meaning that the overall gear ratio is a googol-to-one. (A googol is 1 with 100 zeros.)
This machine has a gear reduction of 1 to 10 a hundred times. In order to get the last gear to turn once you’ll need to spin the first one a google [sic] amount around. Or better said you’ll need more energy than the entire known universe has to do that. That boggles my mind.
You can watch the machine spin for an hour — it’s kinda relaxing:
