52 things I learned in 2020 - Magnetic Notes - Medium
This is Tom Whitwell's annual "52 things I learned" roundup, a grab-bag list of curious facts and findings gathered over the year rather than a single argument—covering everything from why municipal trees are planted male, to the hidden Fetal Bovine Serum in lab-grown meat, to attractive criminals getting lighter sentences, to Warsaw's clam-powered water safety system. It's worth keeping as a dense trivia stockpile with sourced links for each claim, useful for dinner-party facts, writing hooks, or spotting patterns across unrelated fields like tech, biology, economics, and history.
