What is theoretical physics?
Theoretical physics is a branch of the physics area that is devoted to coming to mathematical explanations of natural events. Many disciplines in physics fall under the umbrella of theoretical physics because they include design formulas that may not be empirically tested. Scientists in this area are thinking about some very complex problems and issues such as how the universe has evolved. Scientists usually want to develop theory, propose an experiment that tests this theory, will perform an experiment and publish results. In theoretical physics, scientists develop theories but cannot test them. This separates the theoretical physics from experimental physics in which scientists propose and conduct experiment to explore their theories.
Because theoretical physics cannot be supported by experiments, scientists rely on other tools to determine whether their theories are accurate. The theory should be, for example, capable of exactly PDilute or explain physical phenomena and should be supported by familiar observations. Ideally, the theory should also be clean and elegant, while some theoretical physics signed up to the idea of Occam's razor and believed that the simplest explanation was the best. Theories should also withstand intensive discussion and debate, with theoretical physics who constantly exchange ideas and criticism to improve their field of science.
Some theories in this area have been widely accepted and are commonly taught in classes, are used in physics research and applied in industries around the world. The ongoing research continues because scientists want to fully explore all aspects of theoretical physics. Other theories have been designed and seem credible, but have not been fully supported or required by further research, and the latest theories are considered "marginal theories" that require much more survey, discussions and observations.
sir Isaac Newton is widely considered fromand a pioneer in the field of theoretical physics, as well as Albert Einstein. Both physicists distinguished themselves by making logical jumps that sometimes resisted known information or observation and required a highly theoretical view of the world. Newton's work even included a substantial expansion of the mathematical language in order to express his theories. The theoretical physicists also greatly deal with thought experiments in which they explore their thoughts in their minds, without the use of a laboratory.
