Types of Branches of Natural Sciences: Physical Science
Physical Science is a science that deals with the study of the inorganic world or non-living world. Physical science differs from biological sciences, which study living organisms, as it studies non-living systems, including the learning of energy, matter, and the connections between them. It is a wide collection of fields, all of which add to the knowledge of the universe. The list of Physical Science subfields is as follows:
Physics
The most basic science that studies matter, energy, space, and time. It studies ideas like motion, force, gravity, electricity, magnetism, light, and the structure of atoms. Physicists use experimental work and mathematical modeling to put theories on a rigorous footing and arrive at new theories. Physics is a vast field with many branches. Classical physics describes macroscopic phenomena like mechanics, thermodynamics, and electromagnetism. Conversely, modern physics investigates the quantum realm, addressing the behavior of matter at atomic and subatomic scales, in addition to relativity theories.
Chemistry
Chemistry is referred to as the science of matter, particularly dealing with chemical reactions, their structures, properties, and chemical composition. At its heart, it explores the substances and compounds that fill our world and the changes they undergo. Chemists study the basic building blocks of matter: atoms, molecules, and ions. They examine how these particles interact to form various substances and how these substances can be transformed into new ones through chemical reactions. From the development of new materials and medicines to understanding environmental processes, chemistry plays a vital role in modern society.

Chemistry is Mainly Divided Into Three Subdomains:
Inorganic chemistry: Inorganic chemistry refers to the branch that involves the study of compounds that do not contain carbon-hydrogen bonds. This broad field covers the properties, structures, and reactions of the elements and their compounds, except organic compounds. One way to classify inorganic compounds is by grouping them into acids, salts, bases, and oxides. This includes metals, minerals, and allotropes of carbon like carbon monoxide (CO) and carbon dioxide (CO₂).
Organic Chemistry: It is referred to as the branch of chemistry that studies carbon compounds. It studies the composition, properties, structure, reactions, and preparation of molecules that are organic in nature. Organic chemistry studies functional groups, reaction mechanisms, stereochemistry, and spectroscopy, among others. Their work is fundamental to the creation of pharmaceuticals, polymers, dyes, and other essential products.
Physical Chemistry: It bridges the gap between physics and chemistry, applying the principles of physics to understand chemical systems. It explores the underlying physical principles governing chemical phenomena. Key areas within physical chemistry include thermodynamics (energy and heat transfer), quantum chemistry (behavior of matter at atomic and subatomic levels), kinetics (reaction rates), spectroscopy (interaction of matter with electromagnetic radiation), and electrochemistry (chemical processes involving electric currents). By understanding these fundamental concepts, physical chemists contribute to advancements in materials science, nanotechnology, and energy research.
Earth Sciences
Earth sciences, or geosciences, are the scientific studies of our planet Earth. This field of study juxtaposes Biological, Chemical, and Physical processes that govern the Earth as a complex system. It investigates the solid, liquid, and gaseous totality of the Earth, including rocks, minerals, water, air, and life itself.
Major fields in earth sciences comprise Meteorology (study of the atmosphere and the weather), Geology (study of rocks and the structure of the earth), Oceanography (study of oceans), and Environmental Science (study of the impacts of humans on the environment). Collectively, these disciplines enable us to comprehend where the Earth has come from, where it currently is, and where it is headed.
Types of Branches of Natural Sciences: Biological Sciences
It is referred to as the scientific analysis of living organisms and life, and their composition, function, development, origin, distribution, and evolution are called the biological sciences or life sciences. From the study of cells and small-microscopic organisms to complex life forms and ecosystems of our planet. At the core of biology is the study of life in its most basic forms and functions: growth, reproduction, metabolism, and heredity. Biology is the study of the origin, evolution, distribution, structure, function, and taxonomy of living organisms. What we learn from this data is key to tackling disease, climate change, and food security around the world.
There are so many branches working in this field, which is said to be a specific aspect of life. Unsurprisingly, there are many sub-disciplines of biology; for example, botany (plants), zoology (animals), microbiology (micro-organisms), genetics (heredity), and so on. Other branches include biochemistry, molecular biology, ecology, and physiology. These disciplines interact and overlap often and allow for a holistic view of the living world.

Branches of Sciences: Formal Science
Formal sciences are not considered scientific because they do not focus on nature or the social world, but instead deal with abstractions such as mathematics. These fields use logic and mathematical structures to describe and reason about these abstract objects. Contrasting with other branches, the formal sciences are not concerned about the validation of theories. When considering their reference to the real world (empirical knowledge), in other words, with the properties of proper systems, when considering their axioms and inference rules. Therefore, there is a division of opinion on whether the formal sciences can be considered as science or not. Formal scientific methods are important to the testing and formulation of scientific models addressing processes of the observable reality, and major advances in formal sciences have repeatedly cemented the way to major advances in the field of empirical sciences.
Characteristics of Formal Science
- Abstractness: Formal sciences focus on concepts and abstractions without specific significance in the physical world. These units of meaning are usually encoded as symbols or mathematical formulas.
- Deductive Reasoning: Deduction, the process of deriving logically from general principles to arrive at facts, is the primary method of inquiry for the formal sciences. This is a philosophy that enables the establishment of fresh insights based on current ideas.
- Axiomatic Systems: Many formal sciences are modeled using systems of axioms, a set of axioms. These axioms are the axioms from which you derive other statements, and you accept them without proof.
- Formal Language: Formal sciences employ a system of symbols and rules for combining them, which are called formal languages, and are precise and unambiguous. These are just (just in case definition) two of the many languages that allow us to communicate and analyze common ground.
Logic
Logic is the formal, systematic study of valid inference. It studies the principles and methods of valid inference and deduction. Logic, the basis for sound arguments and conclusions, specifies the content of formal sciences.
- Formal logic concentrates on the form of argument, irrespective of its matter. It studies how conclusions follow from premises, according to the rules of inference. It deals with the study of propositions, which are statements that have a truth value (true or false), and the logical connectives that join them (including, for instance, “and,” “or,” “if-then” and “not”).
- Mathematics: A Formal science most famously includes mathematics. It is concerned with numbers, quantities, shapes, and the relationships between them. Mathematics is everywhere, applied to nearly every discipline of human activity, from physics and engineering to economics and finance.
- Computer Science: Computer science is an academic discipline that is relatively young and focuses on the theory, design, development, and application of computers and computer-based systems. It covers diverse topics, from algorithms and data structures to programming languages and artificial intelligence.
- Statistics: Statistics is the art of collection, organization, analysis, interpretation, and presentation of data. It delivers techniques for making generalizations about populations from sample data. The use of statistics is common in social sciences, economics, medicine, etc.
Applications of Formal Science
Formal sciences cover a wide range of applications in different fields. Some notable examples include:
- Engineering: The formal sciences, especially mathematics and physics, are crucial to the formulation and analysis of engineering structures and systems.
- Physics: The physical sciences use the structures provided by the formal sciences.
