85 Big Ideas that Changed the World
ccnull writes "Forbes just put out its well thought-out list of 85 breakthroughs since 1917 (sneakers) that have revolutionized the way we live. This is interesting on a number of levels -- crazy trivia (the microprocessor and the answering machine invented in the same year!?), a reminder of the past (the modem: 1962), and a frightening realization that not much of interest has come out of the last 10 years (a whopping 4 of the 85 ideas). Easily digestible and worth discussing."
Without this, motor cars wouldn't have been practical. And frankly the replacements don't work as well- lead protects valve seats far, far better.
