 ====== Physical science ======
-Physical science is a branch of science that deals with the study of non-living systems and the fundamental principles that govern the behavior of matter and energy. It encompasses various disciplines, including physics, chemistry, astronomy, and Earth sciences. Physical science seeks to understand the fundamental laws, principles, and processes that govern the natural world.
+There are four physical sciences: [[physics]], [[chemistry]], [[earth sciences]] and [[astronomy]].
-Here are some key areas within physical science:
-  - Physics: Physics is the study of matter and energy, their properties, interactions, and the forces that govern them. It explores topics such as mechanics, thermodynamics, electromagnetism, optics, quantum mechanics, and relativity.
-  - Chemistry: Chemistry focuses on the composition, properties, structure, and behavior of matter. It investigates the elements, compounds, and reactions that occur between them. Chemistry encompasses organic, inorganic, physical, analytical, and biochemistry.
-  - Astronomy: Astronomy is the study of celestial objects, such as stars, galaxies, planets, and the universe as a whole. It examines their properties, motion, formation, and evolution, using observations, theoretical models, and advanced instruments.
-  - Earth Sciences: Earth sciences include geology, meteorology, oceanography, and atmospheric science. They study the Earth, its structure, processes, and history. Geology explores the formation and composition of rocks, while meteorology focuses on weather patterns and atmospheric phenomena. Oceanography examines the oceans, and atmospheric science investigates the Earth's atmosphere.
-These disciplines within physical science often intersect and overlap, as they share common principles and methodologies. They provide a foundation for understanding the natural world and have practical applications in fields such as engineering, technology, medicine, and environmental science.
