Postmodern science began in the 1980s as postwar kids got tenure and became journal editors, society presidents, lab chiefs and department heads - replacing all those who were young adults during the heady war years of Big Science, Reductionism, Determinism and who were educated in the classical science of Newton, Dalton, Darwin and Lyell.
But why didn't these kids - call them Boomer kids if you wish - simply carry on the tradition as their scientific fathers and grandfathers had done for centuries before them ?
