Science
The word science comes from the Latin "scientia," meaning knowledge.
How do we define science? According to Webster's New Collegiate Dictionary, the definition of science is "knowledge attained through study or practice," or "knowledge covering general truths of the operation of general laws, esp. as obtained and tested through scientific method [and] concerned with the physical world."
What does that really mean? Science refers to a system of acquiring knowledge. This system uses observation and experimentation to describe and explain natural phenomena. The term science also refers to the organized body of knowledge people have gained using that system. Less formally, the word science often describes any systematic field of study or the knowledge gained from it.
What is the purpose of science? Perhaps the most general description is that the purpose of science is to produce useful models of reality.
Most scientific investigations use some form of the scientific method. You can find out more about the scientific method here.
Science as defined above is sometimes called pure science to differentiate it from applied science, which is the application of research to human needs. Fields of science are commonly classified along two major lines:
- Natural sciences, the study of the natural world, and
- Social sciences, the systematic study of human behavior and society.
Research can be defined as the search for knowledge, or as any systematic investigation, to establish novel facts, solve new or existing problems, prove new ideas, or develop new theories, usually using a scientific method. The primary purpose for basic research (as opposed to applied research) is discovering, interpreting, and the development of methods and systems for the advancement of human knowledge on a wide variety of scientific matters of our world and the universe.
Scientific research relies on the application of the scientific method, a harnessing of curiosity. This research provides scientific information and theories for the explanation of the nature and the properties of the world around us. It makes practical applications possible. Scientific research is funded by public authorities, by charitable organizations and by private groups, including many companies. Scientific research can be subdivided into different classifications according to their academic and application disciplines.
Etymology
Ibn al-Haytham (Alhazen), 965–1039, Basra - one of the early figures in the development of scientific method.
As per the Merriam-Webster Online Dictionary, the word research is derived from the Middle French " recerche ", which means "to go about seeking", the term itself being derived from the Old French term " recerchier " a compund word from "re-" + "cerchier", or "sercher", meaning 'search'.[1] The earliest recorded use of the term was in 1577.[1]
