Why Study Physics?

Physics is the study of the mechanical universe.  It is the basic science that underlies all the natural sciences.  It is a search for the basic rules of the behavior of matter and energy on every scale:  from the interaction of subatomic particles, to the motion of every day objects, to the evolution of galaxies.  Physics consists of many sub-fields, including particle and nuclear physics, atomic and molecular spectroscopy, optics, solid state physics, biological and medical physics, computational physics, acoustics, astrophysics and cosmology.

Discoveries by physicists, like quantum phenomena and the theory of the Big Bang, have literally transformed our view of the natural world.  Inventions like the transistor and the laser have fueled the modern technological revolution.  We can look forward to even more exhilarating breakthroughs in the future – a future that holds exciting opportunities for the physics students of today.
