Matt Ridley's Facts vs Science Paradigm

No models, no science. More facts better models. Why can't Matt Ridley take on board the scientific epistemic?



The Ptolemaic model of the heavens was actually not bad at making predictions, but  philosophical presuppositions which permitted only the use of circular motions with all measurements being made relative to the earth gave the model a limited sell-by-date. The use of epicycles was a crude kind of Fourier analysis that would require more and more harmonics to be added in order to converge on the observed motions


With motions measured relative to the Sun the Copernican system, although initially based on Sun centred  circular motions, opened up new theoretical potential leading in turn to Digges, Galileo, Kepler, Newton, Einstein and finally Poincare's chaos calculations, each ushering in a conceptual departure which embraced new anomalies in the incoming data. Atomic theory went through similar phases from Rutherford, the Bohr atom, Wilson & Sommerfeld's quantisation rules, Schrodinger & Heisenberg, Dirac & Feynman; but where was gravity in all this? The overall lesson is that even the best models never quite capture everything about the creation.
