By Rick Korzekwa, 22 April 2020 During our investigation into discontinuous progress[note]By ‘discontinuity’, I mean a jump in technological progress that happened at least ten years earlier than it would have taken had the preceding trend held. For example, from 1826 to 1929, the record for the longest suspension bridge span increased from 176 meters to 564 meters, for an average rate of 3.8 meters per year. In 1931, the George Washington Bridge broke the record by more than 500 meters, which would have taken more than a century at 3.8m/year. For more details, see
