Physics is the study of how matter and energy relate to each other, and how they affect one another other through space and over time. How was the universe born? When was it born? How was it made? What is it made of? How does it evolve and change? How is its behavior governed? These are the types of questions that Physicists endeavor to answer.
The study of Physics can be broken down in to two high level categories. Classical Physics and Modern Physics. Classical Physics is physics principally based on the theories of special and general relativity, published by Albert Einstein. Modern physics is physics at the subatomic level. Modern Physics encompasses quantum theory, quantum mechanics, quantum chemistry, particle physics, and nuclear physics. Modern Physics strives to understand life at the atomic and subatomic level. Some of the theories drawn from modern physics clash and bring in to question some of the theories from classical physics.
Physicists design and carry out scientific experiments with a wide variety of tools and equipment including, mass spectrometers, lasers, telescopes (astronomy), to name but a few. They draw observations from these experiments that help them to solve problems and answer questions regarding the forces of nature.

Applied Physics is a field in which physicists perform research with a view to develop new technologies. Often researchers in this field will have a clear objective for their research projects - for example to design and build a new device. Researchers involved in pure physics often-just work on theory, that is to say they simply want to understand more about the world we live in. Researchers in applied physics often draw upon the knowledge and theories devised by researchers working in pure physics.
