Science(from theLatinwordscientia, meaning "knowledge")[1]is a systematic enterprise that builds and organizesknowledgein the form oftestableexplanationsandpredictionsabout theuniverse.[2][3][4]

The earliest roots of science can be traced toAncient EgyptandMesopotamiain around 3500 to 3000 BCE.[5][6]Their contributions tomathematics,astronomy, andmedicineentered and shaped Greeknatural philosophyofclassical antiquity, whereby formal attempts were made to provide explanations of events in thephysical worldbased on natural causes.[5][6]After thefall of the Western Roman Empire, knowledge ofGreek conceptions of the worlddeteriorated inWestern Europeduring the early centuries (400 to 1000 CE) of theMiddle Ages[7]but was preserved in theMuslim worldduring theIslamic Golden Age.[8]The recovery and assimilation ofGreek worksandIslamic inquiriesinto Western Europe from the 10th to 13th century revived "natural philosophy",[7][9]which was later transformed by theScientific Revolutionthat began in the 16th century[10]asnew ideas and discoveriesdeparted fromprevious Greek conceptionsand traditions.[11][12][13][14]Thescientific methodsoon played a greater role in knowledge creation and it was not until the19th centurythat many of the institutional andprofessionalfeatures of science began to take shape;[15][16][17]along with the changing of "natural philosophy" to "natural science."[18]

Modern scienceis typically divided into three majorbranchesthat consist of thenatural sciences(e.g.,biology,chemistry, andphysics), which study nature in the broadest sense; thesocial sciences(e.g.,economics,psychology, andsociology), which study individuals and societies; and theformal sciences(e.g.,logic,mathematics, andtheoretical computer science), which study abstract concepts. There is disagreement,[19][20]however, on whether the formal sciences actually constitute a science as they do not rely onempirical evidence.[21]Disciplines that use existing scientific knowledge for practical purposes, such asengineeringand medicine, are described asapplied sciences.[22][23][24][25]

Science is based onresearch, which is commonly conducted inacademicandresearch institutionsas well as ingovernment agenciesandcompanies. The practical impact of scientific research has led to the emergence ofscience policiesthat seek to influence the scientific enterprise by prioritizing the development ofcommercial products,armaments,health care, andenvironmental protection.
