Lecture One, The Law of Gravitation:

Feynman ended the first of his famous 1964 Messenger Lectures at Cornell University, a talk entitled 'The Law of Gravitation, an Example of Physical Law.' (See above.) The lectures were intended by Feynman as an introduction, not to the fundamental laws of nature, but to the very nature of such laws.
