Physical importance of physics knowledge?
Answers
Physics generates fundamental knowledge needed for the future technological advances that will continue to drive the economic engines of the world. ... Physics is an important element in the education of chemists, engineers and computer scientists, as well as practitioners of the other physical and biomedical sciences.
Once you understand how the universe works, you might be able to use that knowledge to your advantage. Nearly every piece of electronics equipment since the transistor is the result of our understanding quantum mechanics, a 20th century physics discovery. You could go on for quite a while listing proven and developing technologies that rely on physics discoveries.
The fundamentals of physics (the stuff Newton figured out several centuries ago and Maxwell&friends put together a couple centuries ago) are the foundation of just about every field of engineering there is. So every engineer or scientist of any stripe needs to know these basics.
