What are the 4 Main Branches Of Science?

Science is a way of studying nature and the physical world around us. There are many different types of science, but they all have certain things in common. In this article, we will explore the four major branches of science

What are the 4 Main Branches Of Science?

The 4 main branches of science are the following:

  • Physical Science
  • Social Sciences
  • Biological Science
  • Mathematics 

By defining these four branches, we can get a better understanding of what science is and what it is used for.

What is Science?

Science is one of the most influential and important disciplines in the world. Research has shown that science is also one of the most misunderstood subjects in the world because it is a wide field that encompasses almost all disciplines and bodies of knowledge that we know of. 

Science is a body of knowledge that comprises all fields of scientific study. It is the systematic study of the universe and everything in it, and it is the process of acquiring knowledge about the universe by rigorous observation, measurement, experimentation, and critical analysis. 

Science is the systematic study of the natural world and the human beings who study it. It is a systematic, empirical, and logical body of knowledge that grows and changes through observation, experimentation, and reasoning. 

Science is based on evidence gathered from observations, experiments, and the scientific method. Science is a way of investigating the natural world and the human beings who live in it. 

Scientists study the physical universe, life, and living things. They use a systematic approach to gather evidence through observation, experimentation, and reasoning. 

They use this evidence to develop theories and make predictions about what will happen in the future. Scientists use their theories and predictions to develop new ways of understanding the world and to make new discoveries.

What is the scientific method?

The scientific method is a process that is used to test hypotheses and theories in the natural sciences. It aims to give reliable and valid results. This process has three steps. 

  • The first step is to develop a testable hypothesis. The hypothesis is a possible explanation for a phenomenon. 
  • The second step is to gather information about the phenomenon. This step requires research, observation, and experimentation. 
  • The third step is to draw conclusions about how the phenomenon actually works. This process is repeated until sufficient evidence is collected to support the hypothesis, or reject it.

Science is a method of investigating the universe and all its phenomena by observation, experimentation, and testing. It is a systematic approach that is based on empiricism, logic, and reason. 

It is a process that is based on gathering evidence, testing predictions, and revising theories and models. It is not just a collection of facts, but rather a way of thinking about the world.

There are many different fields in science, including physical science, social sciences, biological science, mathematics, and many more. Science is constantly expanding and changing. There is always something new to learn, and that is what makes science so exciting.

Physical Science

Physical science is the study of the natural world around us. It is the study of matter and energy and how we can use these to understand the world around us. 

It is a branch of science that studies the natural world in which we live. It is also an umbrella term that includes physics, chemistry, and astronomy.

Physical science is a very broad field of study. It is one of the most fundamental of the sciences and the most basic. The physical sciences are divided into different branches and sub-fields like physics.

Physics is the science that is concerned with the study of matter and energy. It is the study of what is happening on the atomic and molecular levels.

All in all, the word physical refers to the natural world but can also refer to the physical sciences in general.

Social Sciences

The social sciences are a group of academic disciplines that deal with society and people. They focus on things like sociology, anthropology, and psychology. 

There are four main branches of science in the social sciences:

  • Anthropology
  • Sociology
  • Criminology
  • Psychology

Social science is also a  term that is used to refer to the different fields that study relationships between humans, both as individuals and in groups. These fields of study also include social anthropology, sociology, cultural studies, psychology, political science, and more.

Biological Science

Biological science is the study of life and living things. Biological science is the study of how living things are classified in to different categories, how they are related, and how they grow and change over time. 

It is important to note that biological science is not the study of how living things exist or how they came to be. That is the study of history and evolution. Biological science is the study of living things and how they interact with each other and their environment.


Mathematics is the study of quantity, shape, and space. Logic is the study of reasoning or the principles of thinking. It is the study of quantity, structure, and space. 

Mathematics is a very powerful tool. It has been used over the history of humanity to explore the unknown and to make predictions, especially about numbers and measurements

All numbers have unique properties that can be modified by other numbers. There are many different types of numbers such as integers, rational numbers, and irrational numbers. Each type has its own rules and characteristics that can be used to solve differential equations.

Mathematics is the science of quantity and structure. It is the study of quantitative relationships and the rules and methods used to find the shapes and structures of space. 


Science is the systematic study of the natural world, and is an integral part of human society. Science, as an approach to uncovering how everything works, is very vast that it touches everything that we know and understand in our expanding universe. For us to make sense of this large body of knowledge in a logical way, science is divided into different branches. The 4 main branches of science are physical science, social sciences, biological science, and mathematics.

Frequently  Asked Questions (FAQs): what are the 4 main branches of science?

Who is the Father of science?

Galileo was named the “father of modern science” by Albert Einstein.  Galileo Galilei was born in Pisa, Italy on February 15, 1564. 

The different branches of biological science are the following:

  • Botany
  • Conservation
  • Cology
  • Evolution
  • Genetics
  • Marine Biology
  • Medicine
  • Microbiology
  • Molecular Biology
  • Physiology
  • Zoology

What is the difference between science and philosophy? 

Science is a method of inquiry that uses observation and experimentation to establish facts or to verify hypotheses. Philosophy is a broad discipline dealing with such topics as ethics, metaphysics, epistemology, logic, and aesthetics.
