Knowing these principles of physics helps an athlete or coach improve performance. X-rays, computed tomography, CT scans, and magnetic resonance imaging are used to determine bone damage, diagnose disease, and develop treatment for various illnesses. Technicians who use imaging equipment need to be familiar with the concepts of x rays and magnetic resonance, and to be able to determine how much of this powerful technology to use. Imaging technicians work at hospitals, medical colleges, and clinics. Today's automobiles are a far cry from those put on the road by Henry Ford.
Computers play a major role in how cars operate.
Computers are also used by mechanics to diagnose auto malfunctions. A basic understanding of computer technology is essential in almost every career. Environmental physicists are studying ozone layer depletion and other problems involving the atmosphere. They use acoustics to try to reduce noise pollution. They search for cleaner forms of fuel, study how smog forms and how to reduce it, and devise ways in which to dispose of and store nuclear waste safely.
