Цитата:
Scientific American, September 1999
"Scientists and Religion in America"
"Whereas 90% of the general population has a distinct belief in a personal god and a life after death, only 40% of scientists on the B.S. level favor this belief in religion and merely 10 % of those who are considered 'eminent' scientists believe in a personal god or in an afterlife."
