Science
Science (from the Latin scientia, meaning "knowledge") is a systematic enterprise of gathering knowledge about the world and organizing and condensing that knowledge into testable laws and theories. As knowledge has increased, some methods have proved more reliable than others, and today the scientific method is the standard for science. It includes the use of careful observation, experiment, measurement, mathematics, and replication — to be considered a science, a body of knowledge must stand up to repeated testing by independent observers. The use of the scientific method to make new discoveries is called scientific research, and the people who carry out this research are called scientists. This article focuses on science in the more restricted sense, what is sometimes called experimental science. Applied science, or engineering, is the practical application of scientific knowledge
Science is a broad grouping of disciplines containing many different areas that are all linked together by a single concept – the scientific method. The scientific method represents an investigative method based on observation, deduction, hypothesizing, and experimentation that can be applied to all areas of life. But what are some of the individual types of science that rely on this method? Though there are many ways to look at science, one of the most common is to divide it into three broad categories, each of which contains numerous subdisciplines: formal science, natural science, social science and applied sciences.
Formal science represents those disciplines that deal with symbols and theoretical ideas and their applications in the real world. Its inclusion as a science is often contested, but aspects of formal science are used in all other scientific disciplines. Formal science includes computer science, mathematics, and statistics.
Natural science is the science that people usually think of when they hear the term. Those studying it use the scientific method to understand nature and the physical world. Natural science and its subdisciplines are sometimes referred to as “hard sciences” by their proponents. Natural science includes biology, chemistry, geology, and physics.
Social science is the study of societies and the interactions within them, be they on a group or individual basis. Social science is sometimes referred to as a “soft science” by detractors. Social science includes anthropology, psychology, and sociology.
Each broad scientific category contains many disciplines and subdisciplines with specific research foci. A few of these types of science for each category are:
I Formal Science Disciplines
Computer Science. This type of science focuses on the processing of information in computers and other computational devices. Computer scientists develop new algorithms to process data, improve computer programming languages, and work with many other aspects of computers and programs that modern societies deal with daily.
Mathematics. This is a type of science devoted to the representation and processing of quantities. While the mathematical expression “1 + 1 = 2” may seem simple, it is actually a complex concept filled with semantics. Aspects of mathematics are used by all of the other types of science.
Statistics. Statistics is the collection, analysis, and interpretation of data. While it can be used to find patterns, disprove theories, and make predictions, the science of statistics itself is not focused on any individual real world idea. Instead, the theories and laws in statistics can be applied to any properly formatted data. A Q-Test, for instance, can be used on data gathered from a chemistry, biology, or psychology experiment.
II Natural Science Disciplines
Biology. Biology is the scientific study of life. This study can be very broad, such as how different species might have evolved over millions of years; or it can be very specific, such as what a specific animal eats. Biology has many subdisciplines including botany, entomology, and zoology.
Chemistry. This science studies matter, its states, and how it changes. What individual components things are made of, how they change when exposed to different temperatures, how they can be broken down, and how they can be rebuilt are all questions chemists often ask and try to solve. Subdisciplines of chemistry include biochemistry, food chemistry, inorganic chemistry, and organic chemistry.
Physics. Physics is the study of matter, forces, and interactions. It can be studied on a very large or small scale. The study of how planets and other stellar bodies interact is an example of physics done on a very large scale; the study of subatomic particles represents physics on a small scale. Astronomy, electrodynamics, thermodynamics, and quantum mechanics are all subdisciplines of physics.
III Social Science Disciplines
Anthropology. Anthropology is the study of the origins, development, and uniqueness of human beings. Anthropology borrows from many other disciplines in this study. Branches include archeology, cultural anthropology, and physical anthropology.
Psychology. This is the scientific study of thought and behavior. Understanding why people make the choices they do, how they deal with stress, and predicting what choices they will make in the future are all aspects of psychology. Analytical, behavioral, cognitive, and gestalt are all different schools of psychological thought and theory.
Sociology. Sociology is the scientific study of groups of people. How these groups interact with each-other, the rules of the groups (norms and laws), and how these groups are formed are all aspects sociologists consider
