Theoretical physics involves the use of mathematical models and abstractions to explain and predict physical phenomena. It seeks to understand the fundamental laws of nature, often exploring concepts like quantum mechanics and relativity. Theoretical physicists develop hypotheses that can be tested through experiments. Experimental physics, on the other hand, focuses on conducting experiments to observe and measure physical properties and behaviors. This branch of physics validates or refutes theoretical predictions by gathering empirical data. Experimental physicists often work with advanced technology and equipment to explore areas such as particle physics and condensed matter physics.
