Because physics is the most fundamental of all the natural sciences, and its applications extend even to other areas of human endeavor. Physics is the study of the natural world based on quantitative observations and experiments.
Physics tries to get to the roots of all physical phenomena.
Very important in physics is the use of logical reasoning to make predictions about physical systems. Successful prediction concerning experiments not yet performed is the crucial test for our ideas about the nature of the universe. Physicists see the framework of interrelated concepts as providing an aesthetic satisfaction comparable to that of art and music. Upon graduation, some students will seek employment in industrial research and development or in high school teaching. Other students will pursue graduate study in physics or in related fields such as engineering, mathematics, computer science, or chemistry, or in professional areas such as medicine or law.
