“Are we running out of land for landfills?”: A Richard Feynman view from the 1986 Space Shuttle disaster
Richard Feynman is the Nobel laureate physicist who studied what caused the Space Shuttle Explosion of 1986. He learned that the o-rings likely leaked because past measurements showed cracks in them at low temperatures, like those just before the launch. Anyone my age or older remembers the image. He saw that people who saw the earlier cracks saw that because the cracks only went about a third of the way through, "there was 'a safety factor of three.'" I put the full quote below, which I recommend reading, but the gist is that since the o-rings were designed not to crack at all, there was no safety factor. Any cracking at all meant they failed. The Relevance to Landfills I ran into an old friend. Our…
