The term science in its broadest sense originally denoted the organized body of ascertained and documented knowledge. This first definition is formulated in Plato's Theaetetus, where one of the interlocutors mentions that "science is true glory after reason", that is, science is knowledge confirmed by logical arguments. Many of the human preconceptions about the way the universe works have been challenged from time to time by new scientific discoveries.
