Science is simply common sense at its best, that is, rigidly accurate in observation, and merciless to fallacy in logic.

Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world. Science is the highest personification of the nation because that nation will remain the first which carries the furthest the works of thought and intelligence.

The great tragedy of science - the slaying of a beautiful hypothesis by an ugly fact.

The scientific theory I like best is that the rings of Saturn are composed entirely of lost airline luggage.

Science is the father of knowledge, but opinion breeds ignorance.
