List of life sciences

life scienceslife sciencebioscience
The life sciences or biological sciences comprise the branches of science that involve the scientific study of life and organisms – such as microorganisms, plants, and animals including human beings.

Scientific theory

theoryscientific theoriestheories
Unlike other sciences, the formal sciences are not concerned with the validity of theories based on observations in the real world (empirical knowledge), but rather with the properties of formal systems based on definitions and rules.
The meaning of the term scientific theory (often contracted to theory for brevity) as used in the disciplines of science is significantly different from the common vernacular usage of theory.

Scientific method

scientific researchscientificmethod
Natural science is a branch of science that seeks to elucidate the rules that govern the natural world by applying an empirical and scientific method to the study of the universe.
Although procedures vary from one field of inquiry to another, they are frequently the same from one to another.

Chemistry

chemistchemicalApplied Chemistry
Over the last two millennia, physics was a part of natural philosophy along with chemistry, certain branches of mathematics, and biology, but during the Scientific Revolution in the 16th century, the natural sciences emerged as unique research programs in their own right.
Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.

Biochemistry

biochemistbiochemicalbiological chemistry
It is a physical science which studies various substances, atoms, molecules, and matter (especially carbon based); biochemistry, the study of substances found in biological organisms; physical chemistry, the study of chemical processes using physical concepts such as thermodynamics and quantum mechanics; and analytical chemistry, the analysis of material samples to gain an understanding of their chemical composition and structure.
However, biochemistry as a specific scientific discipline has its beginning sometime in the 19th century, or a little earlier, depending on which aspect of biochemistry is being focused on.

Science

scientificsciencesscientific knowledge
Natural science is a branch of science that seeks to elucidate the rules that govern the natural world by applying an empirical and scientific method to the study of the universe. The branches of science, also referred to as sciences, "scientific fields", or "scientific disciplines," are commonly divided into three major groups: Ecology (from Greek: οἶκος, "house"; -λογία, "study of") is the scientific study of the relationships that living organisms have with each other and with their abiotic environment.
Modern science is typically divided into three major branches that consist of the natural sciences (e.g., biology, chemistry, and physics), which study nature in the broadest sense; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study abstract concepts.

Earth science

Oceanography, or marine biology, is the branch of Earth science that studies the ocean.

Natural science

Over the last two millennia, physics was a part of natural philosophy along with chemistry, certain branches of mathematics, and biology, but during the Scientific Revolution in the 16th century, the natural sciences emerged as unique research programs in their own right. Physics (from ) is a natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force.
Natural science is a branch of science concerned with the description, prediction, and understanding of natural phenomena, based on empirical evidence from observation and experimentation.

Discipline (academia)

Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy.
It includes scientific disciplines.

Index of branches of science

Modern science is typically divided into three major branches that consist of the natural sciences (e.g. biology, chemistry, physics), which study nature in the broadest sense; the social sciences (e.g. psychology, sociology, economics) which study people and societies; and the formal sciences (e.g. mathematics, logic, theoretical computer science), which study abstract concepts.

Biophysical environment

environmentenvironmentalthe environment
Ecology (from Greek: οἶκος, "house"; -λογία, "study of") is the scientific study of the relationships that living organisms have with each other and with their abiotic environment.
Part of this scientific discipline is the investigation of the effect of human activity on the environment.

Social science

social sciencessocial scientistsocial
The term natural sciences is used to distinguish it from the social sciences, which apply the scientific method to study human behavior and social patterns; the humanities, which use a critical, or analytical approach to the study of the human condition; and the formal sciences.

Hard and soft science

Hard science and soft science are colloquial terms used to compare scientific fields on the basis of perceived methodological rigor, exactitude, and objectivity.

Linguistics

These include: anthropology, archaeology, criminology, economics, linguistics, international relations, political science (aka government), public health, sociology, some branches of psychology (results of which can not be replicated or validated easily - e.g. social psychology), and certain aspects of business administration, communication, education, geography, history, and law.

A priori and a posteriori

It is similar to empirical sciences in that it involves an objective, careful and systematic study of an area of knowledge; it is different because of its method of verifying its knowledge, using a priori rather than empirical methods.

Methodology
