The word "science" derives from the Latin scientia, meaning knowledge. Science is a concept that is constantly morphing and changing. The word has many different connotations.

Most commonly, "science" refers to: disciplines or domains of knowledge concerned with empirical observation of the natural world (physics, biology, chemistry, etc.). The word science can also refer more broadly to any discipline of organized knowledge and discourse. This broader definition encompasses, for example: philosophy, psychology, linguistics, and sociology. Finally, the word "science" can also mean: a particular way of reasoning or acquiring knowledge about the world. This definition refers to science as process or method. The scientific method is the core methodology within the natural sciences.

The modern scientific method emphasizes hypothesis, observation, analysis, and use of established paradigms. For example, the germ theory of disease is based on the established paradigm of biological evolution. Similarly, quantum theory rests on established frameworks of electromagnetism and physics. The scientific method also emphasizes collaboration, transparency, and community ethics.

What is science?

Science (from the Latin, scientia – knowledge, knowing) is an epistemology, a way of knowing, and the discipline that incorporates it.  The scientific method is a system of inductive reason, based on trial, experiment, and drawing conclusions from the “proof” of evidence. It uses mathematics, physics, chemistry, and observation to draw conclusions that lead to hypotheses, then theorems, then laws.  As a method of gathering systematic understanding of the universe (especially the physical universe), the conclusions reached by the scientific method are valid only when and if they satisfy all the evidence.  Other ways of knowing (belief, superstition, impression, etc. are others, not acknowledged by the scientific method) have their own validity, but science serves humanity as the primary method for determining “truth.”  There are also “soft sciences” (psychology, sociology, etc.) that cannot submit to strict experimentation, because humanity is not a scientifically predictable entity.

what is science

In simplest terms, Science is the study of everything we see (and we don't see). There are various specialization within science and they deal with physical, chemical, biological and technological aspects. Science includes study of physical (non-living) world which consists of our entire universe, galaxies, planets, solar system, seasons, soil, etc. The chemical aspects of science deal with chemistry and chemical reactions. The biological sciences deal with life, including various life forms (past and present and future), their life processes and related aspects. The technological science deals with the technological marvels we see around us, including transportation means (airplanes, trains, vehicles, etc.), communication devices (cellphones, etc.), amenities, etc.

Science also includes the study of scientific methods, including hypothesis formation and testing, experimental methods and scientific ethics.
