Physics as the Most Fundamental of the Natural Sciences

Physicsis the scientificstudy of matter and energy and how they interactwith each other. This energy can take the form of motion, light, electricity, radiation, gravity... just about anything. Physics deals withmatter on scales rangingfrom subatomic particles (i.e. the particles that make up the atom and the particles that make up those particles) to stars and even entiregalaxies.

Physics is the truly universal sciencethat uncoversa picture of the world that is continually changing. It is the rational developmentof experiments, observationsand theoriesto explain the fundamental structure of all we perceive.

For many students and scientists,Physics is an immensely satisfyingintellectual pursuit.In some areas it is a difficult subject, in others easy, but always it is self consistentand able to explain many aspects of nature. The force of gravity that can be demonstrated in the lecture room is the same force that holds the planets in orbit around the sun and that createsblack holes, among the most intriguing objects in the Universe

Physics deals with fundamentals the nature of space and time, matter and energy, simplicity andcomplexity Physics underpinsall sciences. Many major developments in chemistry, biology, geology and even medicine have been made by physicists. Physics is also the foundation of much modern technology.

In a broader sense,physics can be seen as the most fundamental of the natural sciences. Chemistry, for example, can be viewed asa complex applicationof physics, as' it focuses on the interaction of energy and matter in chemical systems. We also know that biology is, at its heart, an application of chemical properties in living things, which meansthat it is also, ultimately, ruled bythe physical laws.
