The discussion on Albert Einstein's agnosticism/atheism got me thinking: Can anyone name a single great scientist of any time period who also enthusiastically practiced religion? I'm referring to people of the caliber of Albert Einstein, Thomas Edison, Galileo, Copernicus, Pythagoras, Newton, Jonas Salk, Elijah McCoy, Grahm Bell, Archimedes, Euclid, Watt, Da Vinci, Pasteur, Marie Curie and Stephan Hawking. Merely saying one believes in God, or attending religious services out of social coercion doesn't count here. I'd like like to know if a single one of these great minds (or some other brilliant scientist /inventor in their league) found a reason to enthusiastically practice religious rituals regularly. Thank you.
