I am a Lecturer in Theoretical Physics at the University of Cambridge. Before that, I read Great Books at St. John's College (Santa Fe), got my physics Ph.D. from U Maryland, and did my postdocs at UC Santa Barbara, the Institute for Advanced Study in Princeton, and Stanford. The views expressed on this blog are my own, and should not be attributed to any of these fine institutions.
My first pillar of Science is that it is based on repeatable observations. In order to see how Christianity measures up, we need to examine whether it is based on observations, and whether it is repeatable. Observations ultimately boil down … Continue reading →
