“52 Things I Learned in 2021”

posted by Jason Kottke   Dec 01, 2021

Tom Whitwell’s list of 52 things he learned during the past year is always worth a read. Here are some of my favorites from the list:

4. 10% of US electricity is generated from old Russian nuclear warheads. [Geoff Brumfiel]

10. Short afternoon naps at the workplace lead to significant increases in productivity, psychological well-being and cognition. In contrast, an extra 30 minutes sleep at night shows no similar improvements. [Pedro Bessone]

21. Women’s relative earnings increase 4% when their manager becomes the father of a daughter, rather than a son. This daughter effect was found in 25 years of Danish small-business data. [Maddalena Ronchi]

35. Clean rooms used to make semiconductors have to be 1,000x cleaner than a surgical operating theatre, because a single transistor is now much smaller than a virus. [Ian King]

37. The notion of a personal ‘Carbon Footprint’ was invented by Ogilvy & Mather for BP in the early 2000s. [Mark Kaufman]

47. The entire global cosmetic Botox industry is supported by an annual production of just a few milligrams of botulism toxin. Pure toxin would cost ~$100 trillion per kilogram. [Anthony Warner]

Inspired by Whitwell, I have been sporadically compiling my own list throughout the year. I’m going to review it soon and see if there’s anything in there worth publishing. Of course, the 1300+ Quick Links I’ve posted in 2021 work as their own giant list of things I’ve learned this year.
