What is amazing to me, and a bit inspiring, is how late in the game this was. I was born a little afterward, but who here was in school when the plate tectonics revolution came about? Though many of the ideas of plate tectonics were several decades old (including Emile Argand's beautiful and prescient ideas, including continental collision is the biggest driver of mountain range formation, and that subducted Indian crust underlies the Tibetan plateau [1]), until the 70s they were still widely disbelieved, even by straight up geniuses like the great Bayesian geophysicist Harold Jeffreys (he of the Jeffreys prior). Tectonics is the grand unifying theory of geology, and wasn't really accepted until the 70s. How old was 'modern' physics at this point? Darwinian evolution? What else do we still have to discover? I like to keep this in mind when I hear the doubters doubting (e.g., [2]). [1] Argand, E. (1924), "La Tectonique de l'Asie", Extrait du Compte-rendu du XIIIe Congrès géologique international 1922 (Liège), 1(5), pp. 171-372.
