- **Physics**: Physics is a natural science that studies matter, energy, motion, and the interactions between them. It seeks to understand the fundamental laws that govern the universe, whether at the subatomic, atomic, macroscopic, or cosmological scale. Physics covers a wide range of fields, from classical mechanics to quantum physics to astrophysics and particle physics. - **Mathematics**: Mathematics is a fundamental discipline that deals with abstract quantities, shapes, structures, and relationships. It is used to formulate models, solve problems, predict phenomena, and explore abstract concepts. Mathematics includes fields such as algebra, geometry, calculus, number theory, statistics, logic, and many others, and is essential in many scientific and technical fields. - **Chemistry**: Chemistry is the science that studies the composition, structure, properties, and transformations of matter. It examines chemical elements, compounds, and the chemical reactions that occur between them. Chemistry is present in many aspects of everyday life, from biological reactions to the synthesis of new materials to understanding environmental phenomena. The different fields of chemistry include organic, inorganic, analytical, physical, and biochemical chemistry.
