Physics tells us how the physical world works.
Curious about how things work? Interested in the ultimate constituent of matter or how big the universe is? Want to know why the sky is blue but sunsets are orange? Curious about what really happens when you turn on an electric light? Want to have a better understanding of climate change? Want to know why electric motors are 95% efficient but gasoline engines aren’t (and can’t be)? Physics touches on all these questions and much more.
Physics is the study of what governs the natural phenomena in the physical universe from the largest galaxies to the smallest subatomic particles. Physics is the bedrock of science in the sense that it is the basis for all the other physical sciences such as chemistry, computer science, biology, geology, oceanography, and astronomy. Physics is also the basis for nearly all of the technology that we use today to have a more comfortable life.
Physics is the most basic and fundamental science, and is crucial to understanding what governs the natural phenomena in the world in which we live. Much of technology is based on a purposeful application of physics—hence physics is important for an understanding of computers and televisions, cellular phones and music players, and also technologies which change our lives—from medical equipments to developing sustainable energy solutions. Also, studying physics stimulates critical thinking skills, which is why students taking physics courses tend to score higher on the SAT, GRE, LSAT and MCAT. Last but not the least, physics tells us about the wondrous nature of reality itself. It tells us about the birth of the universe, how stars come into being, and the fact that black holes are not a figment of our imagination. Whether you become a physicist, study some other field in science or engineering, or are just curious about the world around you, a course in physics will broaden your world view.
