The Messenger Lectures are a prestigious series of talks given by leading scholars and public figures at Cornell University. They were founded in 1924 by a gift from Hiram Messenger and are regarded as one of the most important of Cornell's extracurricular activities.The Character of Physical Law are a series of seven lectures by physicist Richard Feynman concerning the nature of the laws of physics. The talks were delivered by Feynman in 1964 at Cornell University, as part of the Messenger Lectures series. Their text was published by the BBC in 1965 in a book by the same name.The lectures covered the following topics:The law of gravitation, an example of physical lawThe relation of mathematics and physicsThe great conservation principlesSymmetry in physical lawThe distinction of past and futureProbability and uncertainty - the quantum mechanical view of natureSeeking new lawsRichard Phillips Feynman (May 11, 1918 -- February 15, 1988) was an American theoretical physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics (he proposed the parton model). For his contributions to the development of quantum electrodynamics, Feynman, jointly with Julian Schwinger and Sin-Itiro Tomonaga, received the Nobel Prize in Physics in 1965. He developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime, Feynman became one of the best-known scientists in the world. In a 1999 poll of 130 leading physicists worldwide by the British journal Physics World he was ranked as one of the ten greatest physicists of all timehttp://en.wikipedia.org/wiki/The_Character_of_Physical_Lawhttp://en.wikipedia.org/wiki/Messenger_Lectureshttp://en.wikipedia.org/wiki/Richard_P._FeynmanDisclaimer:Copyright Disclaimer Under Section 107 of the Copyright Act 1976, allowance is made for "fair use" for purposes such as criticism, comment, news reporting, teaching, scholarship, and research.
