The culmination of the Standard model was the discovery of the Higgs boson: earlier this decade at the Large Hadron Collider at CERN.(The Higgs boson-CERN).What happens if genereal relativity really is not valid?
Aristotle is credited with the earliest study of formal logic, and his conception of it was the dominant form of Western logic until 19th century advances in mathematical logic.Kant stated in the Critique of Pure Reason (Preface to the Second Edition, 1787) that with Aristotle logic reached its completion.
Logic, from the Ancient Greek: λογική, originally meaning “the word” or “what is spoken”, but coming to mean “thought” or “reason”, is generally held to consist of the systematic study of the form of arguments. A valid argument is one where there is a specific relation of logical support between the assumptions of the argument and its conclusion. In ordinary discourse, the conclusion of such an argument may be signified by words like therefore, hence, ergo and so on.
