The Forces of Nature
Four fundamental forces rule the universe: gravity, the electromagnetic force and then two that act in and around the atomic nucleus, known as strong and weak. The latter pair act over distances smaller than atoms and so are less familiar to our macroscopic senses than are the effects of gravity and magnets.
However, they are critical to our existence, keeping the Sun burning and providing the essential warmth for life.

|The Forces of Nature|
|The Search for New Particles and Forces
This talk will review the search for new basic interactions in nature and the experimental methods that the LHC brings to this question.
|The Mechanical Universe: Fundamental Forces
From the astronomical to the subatomic, all physical phenomena of nature are explained by four fundamental forces.
|The Character of Physical Law
This consists of seven lectures given by physicist Richard Feynman, concerning the nature of the laws of physics.
|Descriptive Introduction to Physics
This course deals with some of interesting and important topics in physics. It stresses conceptual understanding rather than math, with applications to current events.
