Physics examines universal properties of inanimate nature. While some aspects of nature are not permanent - the shape of Cape Cod or even a spiral arm of a galaxy - the forces that created both Cape Cod and the spiral arm obey universal laws.
Physics is concerned with questions whose answers and ideas must be sought and tested by experiment. In fact, questions are often generated by experimental discovery. There is every reason to believe that answers, once found, have a permanent and universal validity as all evidence indicates that the laws of physics are the same everywhere in the universe.
Introductory physics courses are designed to serve students majoring in many different areas. The algebra-based sequence is designed for students in biology and the health professions, while the calculus-based sequence is designed for students in physics, chemistry, engineering or math.
Advanced physics courses are designed to provide fundamental training for professional work in physics and for teaching physics in secondary schools.
Note that completion of PHY 143, or PHY 143 and PHY 145, or PHY 243 and PHY 245, is prerequisite to certain concentration programs.
