Physics is fundamental natural science dealing with universal laws and principles of the universe. Discoveries in physics had a great impact on all natural sciences, and physics has been described as the fundamental science because other fields such as chemistry, biology, geology or astronomy investigate systems whose properties depend on the laws of physics. The emergence of physics as a science distinct from philosophy began with the dawn of modern science in the 16th and 17th centuries and continued through the revolution in physics at the beginning of the 20th century. The field has continued to expand, with a growing body of discoveries leading to the creation of five fundamental theories.
- Classical mechanics
- Classical electrodynamics
- Thermodynamics and statistical physics
- Quantum theory
- Theory of relativity
