Chronology. Joseph Scaliger's De emendatione temporum (1583) began the modern science of chronology[1] Chronology (from Latin chronologia, from Ancient Greek χρόνος, chronos, "time"; and -λογία, -logia) is the science of arranging events in their order of occurrence in time.

Chronology

Consider, for example, the use of a timeline or sequence of events. It is also "the determination of the actual temporal sequence of past events".[2] Chronology is part of periodization. Social sciences. Social science is an academic discipline concerned with society and the relationships among individuals within a society.

Social sciences

It includes anthropology, economics, political science, psychology and sociology. In a wider sense, it may often include some fields in the humanities[1] such as archaeology, history, law, and linguistics. The term may however be used in the specific context of referring to the original science of society, established in 19th century, sociology (Latin: socius, "companion"; Greek λόγος, lógos, "word", "knowledge", "study. "). Émile Durkheim, Karl Marx and Max Weber are typically cited as the principal architects of modern social science by this definition.[2] Positivist social scientists use methods resembling those of the natural sciences as tools for understanding society, and so define science in its stricter modern sense.

Portal:Spirituality. From Wikipedia, the free encyclopedia The term spirituality lacks a definitive definition, although social scientists have defined spirituality as the search for "the sacred," where "the sacred" is broadly defined as that which is set apart from the ordinary and worthy of veneration.

Portal:Spirituality

The term "spirituality" is derived from the Latin spiritualitas and the Biblical "roeach/pneuma" . It means to be put in motion, to be a living person, and being driven. In a Bibilical context it means being animated by God. The notion of "spiritual experience" plays an important role in modern spirituality, but has a relatively recent origin. Portal:Religion.

Mathematics is the study of numbers, quantity, space, structure, and change.

Portal:Mathematics

Mathematicians seek out patterns and formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proofs, which are arguments sufficient to convince other mathematicians of their validity. The research required to solve mathematical problems can take years or even centuries of sustained inquiry. Portal:Science. Edit The Science Portal Science is formed from methodical study of nature stemming from testable explanations and predictions.

An older and closely related current meaning emerged from Aristotle, whereby "science" referred to the body of reliable knowledge that is logically and rationally explained (see "History and etymology" section below). Since classical antiquity, science as knowledge was closely linked to philosophy. Portal:History. Portal:Health and fitness.
