Is Computer Science A Natural Science?

As technology continues to evolve and impact our lives in unprecedented ways, the field of computer science has taken on growing importance and visibility. But there remains some debate around how this relatively new discipline should be categorized in relation to other branches of science.

If you’re short on time, here’s the quick answer: Computer science is generally not considered a natural science like physics, chemistry or biology. It is most commonly classified as a formal science, which focuses on logic, mathematics and theoretical computer modeling rather than natural processes.

In this in-depth guide, we’ll look at definitions of natural science versus formal science, analyze the characteristics of computer science, and determine why most academics place computer science among the formal rather than natural sciences.

Defining the Natural Sciences

When discussing the field of computer science, a question often arises: Is computer science a natural science? To answer this question, it is important to first understand what exactly is meant by the term “natural sciences.”

Study of the Physical World

The natural sciences, also known as physical sciences, are disciplines that focus on the study of the physical world and its phenomena. These sciences aim to understand the laws and principles that govern the natural world and explain its behavior through observation, experimentation, and analysis.

Fields such as physics, chemistry, biology, and geology are considered natural sciences because they deal with the study of natural phenomena, ranging from subatomic particles to ecosystems. These disciplines seek to uncover the fundamental principles that govern the physical universe.

Emphasis on Empiricism

One key characteristic of the natural sciences is their emphasis on empiricism. This means that these disciplines rely heavily on observation and experimentation to gather data and test hypotheses. The scientific method, a systematic approach to conducting research, is commonly used in the natural sciences to ensure objectivity and accuracy.

Computer science, on the other hand, is primarily concerned with the study of algorithms, computation, and information processing. While it does involve experimentation and empirical analysis in certain areas, such as artificial intelligence or computational biology, its focus is not primarily on the physical world.

Branches of Natural Science

There are several branches within the natural sciences, each with its own specific focus and methodologies. Physics, for example, explores the fundamental principles of matter and energy, while chemistry investigates the composition, properties, and reactions of substances.

Biology, on the other hand, examines living organisms and their interactions with the environment.

Computer science, although not a natural science itself, can intersect with these branches in various ways. For instance, computational physics uses computer simulations to study complex physical systems, while bioinformatics utilizes computational tools to analyze biological data.

These intersections highlight the interdisciplinary nature of computer science and its ability to contribute to the natural sciences.

Computer Science as a Formal Science

Computer Science is often categorized as a formal science due to its focus on abstract thinking and problem-solving. Unlike natural sciences, such as biology or chemistry, which study phenomena in the natural world, computer science deals with the study of algorithms, computation, and information processing.

Focus on Abstract Thinking

One of the key aspects of computer science as a formal science is its emphasis on abstract thinking. Computer scientists often work with complex concepts and theories that may not have direct counterparts in the physical world.

They develop algorithms and models that can be applied to various domains, ranging from artificial intelligence to cryptography. By focusing on abstract thinking, computer scientists can create innovative solutions to real-world problems.

Mathematical Logic and Reasoning

Mathematical logic and reasoning play a crucial role in computer science. Computer scientists use mathematical concepts and principles to analyze and design algorithms, data structures, and programming languages.

They utilize mathematical logic to prove the correctness of algorithms and to reason about the behavior of computer systems. This strong foundation in mathematics distinguishes computer science as a formal science.

Conceptual Modeling and Simulation

Conceptual modeling and simulation are integral parts of computer science. Computer scientists develop models and simulations to represent complex systems and phenomena. These models help in understanding and predicting the behavior of real-world systems, such as weather patterns or economic markets.

Through conceptual modeling and simulation, computer science contributes to advancements in various fields, including engineering, medicine, and social sciences.

Computer science may not fit neatly into the traditional classification of natural sciences, but its status as a formal science is well-established. Its focus on abstract thinking, mathematical logic, and conceptual modeling distinguishes it from other scientific disciplines.

By leveraging these unique attributes, computer scientists continue to push the boundaries of technology and contribute to the advancement of human knowledge.

Key Differences From Natural Science

Does Not Study Natural Phenomena

Unlike natural science, computer science does not primarily focus on studying natural phenomena in the physical world. Natural science disciplines such as physics, chemistry, and biology are concerned with understanding the laws and processes that govern the natural world.

Computer science, on the other hand, deals with the study of computation, algorithms, and information processing.

While natural science seeks to uncover the underlying principles that govern the natural world, computer science is more concerned with the development and application of algorithms and software systems that facilitate various tasks and processes.

Relies on Deductive Reasoning

Computer science heavily relies on deductive reasoning to solve complex problems and develop efficient algorithms. Deductive reasoning involves using logical thinking and inference to arrive at conclusions based on given premises.

It allows computer scientists to analyze problems, break them down into smaller components, and develop step-by-step solutions.

By leveraging deductive reasoning, computer scientists can create software systems that perform specific tasks, handle large amounts of data, and solve complex computational problems. This logical approach distinguishes computer science from natural science, which often relies on inductive reasoning to formulate hypotheses and theories based on observations and experiments.

Concerned With Man-Made Systems

Computer science is primarily concerned with man-made systems, such as computer hardware, software, and networks. It focuses on understanding how these systems work, improving their efficiency, and developing new technologies that advance the field.

Natural science, on the other hand, is concerned with studying the natural world and its processes, including the physical, chemical, and biological aspects of nature. While computer science may draw inspiration from natural phenomena to solve certain problems (e.g., using algorithms inspired by biological processes), its main focus remains on the development and analysis of man-made systems.

Debate Around Classification of Computer Science

Overlaps With Mathematics and Engineering

When it comes to the classification of computer science, there is an ongoing debate among scholars and experts. One argument is that computer science is a natural science due to its close relationship with mathematics and engineering.

Computer science heavily relies on mathematical concepts and algorithms to solve complex problems. The field also intersects with engineering principles, as computer scientists design and build hardware and software systems.

Computer science and mathematics share many common elements, such as logic, algorithms, and problem-solving techniques. The two disciplines often collaborate in areas like cryptography, data analysis, and optimization.

In fact, computer scientists often use mathematical models and theories to develop new algorithms and systems. This overlap between computer science, mathematics, and engineering blurs the lines between natural sciences and applied sciences.

Rapid Pace of Technological Progress

Another factor that adds to the debate is the rapid pace of technological progress in computer science. The field is constantly evolving, with new technologies and methodologies emerging at an astonishing rate.

This rapid progress challenges traditional categorizations and makes it difficult to confine computer science solely to the realm of natural sciences.

Advancements in artificial intelligence, machine learning, and quantum computing are transforming the way we approach scientific research and problem-solving. These cutting-edge technologies have the potential to revolutionize various fields, including healthcare, finance, and transportation.

The dynamic nature of computer science makes it an interdisciplinary field that bridges the gap between natural sciences and applied sciences.

Ongoing Evolution of Academic Disciplines

The ongoing evolution of academic disciplines also contributes to the debate surrounding the classification of computer science. As new areas of study emerge and existing disciplines undergo transformations, the boundaries between natural sciences, social sciences, and applied sciences become increasingly blurred.

Computer science has expanded beyond its initial focus on programming and algorithms to encompass a wide range of sub-disciplines, such as data science, cybersecurity, and bioinformatics. These specialized areas often draw upon concepts and methodologies from other fields, including biology, psychology, and sociology.

This interdisciplinary nature challenges the traditional categorization of computer science as a purely natural science.


While fields like physics, biology and chemistry study the natural world through observation and experimentation, computer science is focused on the theoretical underpinnings of computation and information processing.

Given its foundations in mathematical logic and conceptual modeling rather than natural processes, most academics classify computer science as a formal rather than a natural science.

However, the links between computer science and natural science continue to grow as technology takes on an expanding role in scientific research and discovery. And computer science itself continues to evolve at a rapid pace.

So while the field is unlikely to be reclassified as a natural science anytime soon, the debate around its categorization within scientific disciplines will likely continue.
