Ancient Near East

Ancient Near East
The ancient Near East was the home of early civilizations within a region roughly corresponding to the modern Middle East: Mesopotamia (modern Iraq, southeast Turkey, southwest Iran, northeastern Syria and Kuwait), ancient Egypt, ancient Iran (Elam, Media, Parthia and Persia), Anatolia/Asia Minor and Armenian Highlands (Turkey's Eastern Anatolia Region, Armenia, northwestern Iran, southern Georgia, and western Azerbaijan), the Levant (modern Syria, Lebanon, Palestine, Israel, and Jordan), Cyprus and the Arabian Peninsula. The ancient Near East is studied in the fields of Near Eastern archaeology and ancient history.

Ancient Near East

The history of the ancient Near East begins with the rise of Sumer in the 4th millennium BC, though the date it ends varies: the term covers the Bronze Age and the Iron Age in the region until either the conquest by the Achaemenid Empire in the 6th century BC or that by Alexander the Great in the 4th century BC.
The ancient Near East is considered one of the cradles of civilization. It was here that intensive year-round agriculture was first practiced, leading to the rise of the first dense urban settlements and the development of many familiar institutions of civilization, such as social stratification, centralized government and empires, organized religion and organized warfare. It also saw the creation of the first writing system and law codes, early advances that laid the foundations of astronomy and mathematics, and the invention of the wheel.
During the period, states became increasingly large, until by the end the region was controlled by military empires who had conquered a number of different cultures.

History of science

History of science
The history of science is the study of the development of science and scientific knowledge, including both the natural sciences and social sciences. (The history of the arts and humanities is termed as the history of scholarship.) Science is a body of empirical, theoretical, and practical knowledge about the natural world, produced by scientists who emphasize the observation, explanation, and prediction of real world phenomena. Historiography of science, in contrast, studies the methods by which historians study the history of science.

History of science

The English word scientist is relatively recent—first coined by William Whewell in the 19th century. Previously, people investigating nature called themselves "natural philosophers". While empirical investigations of the natural world have been described since classical antiquity (for example, by Thales and Aristotle), and scientific method has been employed since the Middle Ages (for example, by Ibn al-Haytham and Roger Bacon), modern science began to develop in the early modern period, and in particular in the scientific revolution of 16th- and 17th-century Europe. Traditionally, historians of science have defined science sufficiently broadly to include those earlier inquiries.
From the 18th century through late 20th century, the history of science, especially of the physical and biological sciences, was often presented in a progressive narrative in which true theories replaced false beliefs. Some more recent historical interpretations, such as those of Thomas Kuhn, tend to portray the history of science in different terms, such as that of competing paradigms or conceptual systems in a wider matrix that includes intellectual, cultural, economic and political themes outside of science.
