Elements of Physics: Modern Physics and Cosmology DVD
This is a program on the way that modern physics has revolutionized the way we understand our universe. Physicists found that the sub-atomic world does not follow the laws of classical physics and developed quantum theory to give a more exact explanation. Einstein developed his special theory of relativity to explain what happens when objects travel close to the speed of light and later developed the general theory of relativity, which provided a new explanation of gravity. These theories have shed light on the existence of black holes and the origins of the universe.
