We tackle the first in the series of seven lectures by theoretical physicist Dr. Richard Feynman titled "The Character of Physical Law", this first lecture being on the Law of Gravitation, the history of its discovery, and its wider application in the methods of science and the further discoveries of physics. Copernicus, Tycho, Kepler, Newton, and Einstein are among the giants on whose shoulders modern physics stands.
