Why study Physics or Astronomy? Physics considers the most fundamental forces of nature, and applies the knowledge gained to obtain detailed understanding of complex systems. Astronomy seeks to understand the structure and evolution of the Universe on all scales. In both cases, asking good questions of our understanding of nature often leads to unexpected discoveries. The study of radioactivity eventually led to an understanding of supernovae (when stars explode), and the study of atomic spectroscopy led to the development of the laser and the discovery of the Universe's expansion.
At the introductory level, the study of these disciplines serves to demystify our technological world both by explaining the basic ideas behind many technologies, and by introducing the scientific process (quantified critical thinking). Futher study leading to a Minor, Bachelor of Science Degree, or Bachelor of Arts degree, teaches one classical and quantum physics and how to test theories against reality in the laboratory; this training in independent thinking is valuable for further studies in science, and also in other walks of life.
