… Physicist George Ellis Knocks Physicists for Knocking Philosophy, Falsification, Free Will | Cross-Check, Scientific American Blog Network. (Hat tip, Dave Lull.)
Actually philosophical speculations have led to a great deal of good science. Einstein’s musings on Mach’s principle played a key role in developing general relativity. Einstein’s debate with Bohr and the EPR paper have led to a great of deal of good physics testing the foundations of quantum physics. My own examination of the Copernican principle in cosmology has led to exploration of some great observational tests of spatial homogeneity that have turned an untested philosophical assumption into a testable – and indeed tested – scientific hypothesis. That’ s good science.
