The study of physics is significant because the concepts serve as the basis for more complicated concepts that apply to geology, chemistry and other sciences. Quite a few of the tools that have come from advances in technology and science have come from the result of the work of physicists.
Medical professionals use nuclear magnetic resonance imaging, X-rays, lasers, synchrotron radiation and electron microscopes, all of which function as a result of the operation of the principles of physics. Without a functioning knowledge of quantum mechanics, building the electronic components that form the working parts of computers would not be possible. Traveling any distance in a quick amount of time, communicating across distances and even carrying out business on a global level requires the assistance of physics.
Other examples of the importance of physics include awareness of the effects of natural events. When tsunamis start to rise and threaten devastation, it is the knowledge of physics that helps scientists know which areas of the world's population to warn and the proper precautions that they must take. The principles of physics that involve planetary movement drive the design and function of manmade satellites. Without a knowledge of the basic principles of motion and force, mankind's existence would still be quite primitive.
