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.
