List of Main Branches of Science

In the science world, there are many branches which each branch study different field in human life. In this article, we will explain some branches of science which are useful to understand all aspects of the world and help to develop human life, health, and each other fields.

Branches of Science


It is the science of studying atoms, ions, and molecules. this science is very important because it used to manufacture chemicals and cures. it used to study chemical reactions such as breath, eat, etc. There are many branches of chemistry like:

  • Organic chemistry.
  • Inorganic chemistry.
  • Analytical chemistry.
  •  Physical chemistry.
  • Biochemistry.


It is the science of studying the universe behave and studying of matter, energy, and the interaction between them. Physics is important to study chemists, engineers and computer scientists. it helps to study nature aspects, temperatures, liquids, and electricity. There are many branches of physics such as:

  • Classical physics.
  • Modern physics.
  • Nuclear physics.
  • Atomic physics.
  • Geophysics.
  • Biophysics.
  • Mechanics.
  • Acoustics.


It is the science of studying quantity, structure, space, and change. mathematics is a very important science to help in problem-solving. it helps students develop their lifelong learning skills which include little things like the ability to concentrate in order to study, focusing on tasks, being organized, looking up stuff you do not understand and ability to stay organized. There are many branches of mathematics like:

  • Foundations.
  • Arithmetic.
  • Algebra.
  • Analysis.
  • Combinatorics.
  • Geometry and topology.
  • Probability and statistics.
  • Computational sciences.


It is the science of studying celestial objects such as stars, planets, comets, and galaxies and phenomena. it is focused on acquiring and analyzing data, mainly using basic principles of physics. it is very important to study the space and its aspects to predict the future. There are many branches of astronomy such as:

  • Astrobiology.
  • Astrophysics.
  • Planetary Science.
  • Archaeoastronomy.
  • Astrochemistry.

Human biology

It is the science of studying humans and examine their bodies. it is the study of all living things. it is considered a very important science because it allows humans to better understand their bodies, their resources and potential threats in the environment. There are many branches of human biology like:

  • Genetics.
  • Evolution.
  • Physiology.
  • Anatomy.
  • Epidemiology.
  • Anthropology.
  • Ecology.
  • Nutrition.
  • Population genetics.
  • Sociocultural influences.


It is the science of studying the earth rocks, rivers, Niles, etc. it is very important to predict landslides, earthquakes, floods, and volcanic eruptions can be hazardous to people. and used to predict what is under the earth like petrol. There are many branches of geology like:

  • Structural geology.
  • Mineralogy.
  • Optical geology.
  • Petrology.
  • Oceanology.
  • Hydrology.
  • Environmental geology.
  • Paleontology.


It is the science of studying planets life and multicellular organisms. it is considered a branch of biology. it is very important because they are a fundamental part of life on Earth, generating food, oxygen, fuel, medicine, and fibers that allow other life forms to exist. There are many branches of botany like:

  • Plant biochemistry.
  • Plant ecology.
  • Genetics.
  • Plant evolution.
  • Plant physiology.
  • Plant anatomy and morphology.
  • Systematic Botany.


It is the science of studying weather, atmospheric chemistry, and atmospheric physics. it is a very important science that helps people to predict future weather and weather changes in the future. There are many branches of meteorology such as:

  • Atmospheric Physics.
  • Life science.
  • Weather and climate.
