Physics, science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe. In the broadest sense, physics is concerned with all aspects of nature on both the macroscopic and submicroscopic levels. Its scope of study encompasses not only the behavior of objects under the action of given forces but also the nature and origin of gravitational, electromagnetic, and nuclear force fields. Its ultimate objective is the formulation of a few comprehensive principles that bring together and explain all such disparate phenomena.
Physics is second only to mathematics in the purity of its principles. Physics describes how the natural world works through applied mathematical formulas. It deals with the fundamental forces of the universe and how they interact with matter looking at everything from galaxies and planets to atoms and quarks and everything in between.
Physics is an exciting intellectual adventure that inspires kids and expands its frontiers of knowledge about Nature. It generates fundamental knowledge needed for future technological advances that will continue to drive the economic engines of the world. Early exposure to Physics contributes to the technological infrastructure and provides for trained personnel needed to take advantage of scientific advances and discoveries.
