A Look at the Principles of Physics

Physics is an incredibly complex branch of science dealing with matter. It’s one of the fundamental natural sciences. The point of physics is to describe how the world behaves and how objects move in space and time. For most of us, the concepts of physics are completely incomprehensible, but thanks to quantum mechanics we’re starting to see that it’s not all that strange after all. Basically, the laws of physics state that all events in the world are governed by a single set of principles. In other words, physics describes the way we live.


One of these principles is the theory of relativity. Einstein’s theory of relativity describes how we can’t see anything by merely looking at it. Because the speed of light doesn’t go faster than the speed of the vacuum (the space we live in), we can only see other objects from relatively close distances, which include stars and planets, while the rest of the universe is still nothing more than an immense ocean of radiation.

Albert Einstein was a pioneer in developing new concepts in physics, like special relativity and general relativity. Special relativity describes the way force acts independent of matter and its position in space; it also describes the relationship between electromagnetism and gravity. General relativity describes how the same force that makes an apple fall over a railing works if you place a bowling ball on top of it, for instance. In order to better understand these concepts, you need to learn more about specific theories, like classical mechanics and electrostatics. However, these theories have proven extremely difficult to test and prove. Thanks to the research done by Isaac Newton, however, we now have powerful new tools to test the theories of relativity.
