Science (from the Latin word scientia, signifying "information") is a deliberate venture that constructs and composes information as testable clarifications and expectations about the universe.

The soonest foundations of science can be followed to Ancient Egypt and Mesopotamia in around 3500 to 3000 BCE. Their commitments to science, space science, and medication entered and molded Greek common way of thinking of traditional vestige, whereby formal endeavors were made to give clarifications of occasions in the physical world dependent on normal causes. After the fall of the Western Roman Empire, information on Greek originations of the world crumbled in Western Europe during the early hundreds of years (400 to 1000 CE) of the Middle Ages yet was saved in the Muslim world during the Islamic Golden Age. The recuperation and osmosis of Greek works and Islamic investigations into Western Europe from the tenth to thirteenth century restored "characteristic philosophy",which was later changed by the Scientific Revolution that started in the sixteenth century as new thoughts and disclosures left from past Greek originations and customs. The logical strategy before long assumed a more noteworthy job in information creation and it was not until the nineteenth century that a large number of the institutional and expert highlights of science started to come to fruition; alongside the evolving of "characteristic way of thinking" to "regular science."

Present day science is normally partitioned into three significant branches that comprise of the regular sciences (e.g., science, science, and material science), which study nature in the broadest sense; the sociologies (e.g., financial aspects, brain research, and human science), which study people and social orders; and the conventional sciences (e.g., rationale, arithmetic, and hypothetical software engineering), which study dynamic ideas. There is disagreement,however, on whether the conventional sciences really comprise a science as they don't depend on observational evidence.Disciplines that utilization existing logical information for handy purposes, for example, designing and medication, are depicted as applied sciences.
