Can a scientist be religious?
An empirical answer to the question can a scientist be religious is easy: yes. Religious scientists are actually quite common. However, many would prefer to know whether or not it is rational for them to be religious. Here we need some qualifications on what exactly religious means. If it requires belief in an omnipotent, human-like entity who interferes in the workings of nature, suspending a law here or a rigging a miracle there like a mechanic might fix a car, then Id say no, religion is not rational. Given what we know about our world and cosmos, based on methodologies on which we depend in nearly all aspects of our lives, its not rational to believe that stars hang from a metal firmament in the sky, that the Earth is 6,000 years old, that human virgins have sons, or that decomposed cadavers can come back to life.
