Scientists and their religious beliefs (from wikipedia):
In 1914, James H. Leuba found that 58% of 1,000 randomly selected U.S. natural scientists expressed "disbelief or doubt in the existence of God". The same study, repeated in 1996, gave a similar percentage, of 60.7% (this number is 93% among the members of the National Academy of Sciences). Expressions of positive disbelief rose from 52% to 72%. [5] (See also The relationship between religion and science).
