In his seminal work, ''The Logic of Scientific Discovery,'' Karl Popper repudiated induction, and proposed the bright line of [[Falsifiable|falsifiability]] as a demarcation between science and non-science. In order to be scientific, a theory must be testable, and the results of the testing must either corroborate the theory, or falsify it. A proposed theory is falsifiable, if it is conceivable to conduct an experiment that would disprove the theory. For example, Newton's law of gravity is a valid scientific theory because it is falsifiable; that is, the Law of Gravity is experimentally testable, and a measurement taken that violates Newton's law would falsify it, while a measurement that substantiates the theory would corroborate it, but importantly, would not 'prove' it.
