The History of Science Portal

The history of science covers the development of science from ancient times to the present. It encompasses all three major branches of science: natural, social, and formal. Protoscience, early sciences, and natural philosophies such as alchemy and astrology during the Bronze Age, Iron Age, classical antiquity, and the Middle Ages declined during the early modern period after the establishment of formal disciplines of science in the Age of Enlightenment.

Science's earliest roots can be traced to Ancient Egypt and Mesopotamia around 3000 to 1200 BCE. These civilizations' contributions to mathematics, astronomy, and medicine influenced later Greek natural philosophy of classical antiquity, wherein formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Latin-speaking Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but continued to thrive in the Greek-speaking Byzantine Empire. Aided by translations of Greek texts, the Hellenistic worldview was preserved and absorbed into the Arabic-speaking Muslim world during the Islamic Golden Age. The recovery and assimilation of Greek works and Islamic inquiries into Western Europe from the 10th to 13th century revived the learning of natural philosophy in the West. Traditions of early science were also developed in ancient India and separately in ancient China, the Chinese model having influenced Vietnam, Korea and Japan before Western exploration. Among the Pre-Columbian peoples of Mesoamerica, the Zapotec civilization established their first known traditions of astronomy and mathematics for producing calendars, followed by other civilizations such as the Maya.

Natural philosophy was transformed during the Scientific Revolution in 16th- to 17th-century Europe, as new ideas and discoveries departed from previous Greek conceptions and traditions. The New Science that emerged was more mechanistic in its worldview, more integrated with mathematics, and more reliable and open as its knowledge was based on a newly defined scientific method. More "revolutions" in subsequent centuries soon followed. The chemical revolution of the 18th century, for instance, introduced new quantitative methods and measurements for chemistry. In the 19th century, new perspectives regarding the conservation of energy, age of Earth, and evolution came into focus. And in the 20th century, new discoveries in genetics and physics laid the foundations for new sub disciplines such as molecular biology and particle physics. Moreover, industrial and military concerns as well as the increasing complexity of new research endeavors ushered in the era of "big science," particularly after World War II. (Full article...)

The 1871 periodic table constructed by Dmitri Mendeleev. The periodic table is one of the most potent icons in science, lying at the core of chemistry and embodying the most fundamental principles of the field.

The history of chemistry represents a time span from ancient history to the present. By 1000 BC, civilizations used technologies that would eventually form the basis of the various branches of chemistry. Examples include the discovery of fire, extracting metals from ores, making pottery and glazes, fermenting beer and wine, extracting chemicals from plants for medicine and perfume, rendering fat into soap, making glass, and making alloys like bronze.

The protoscience of chemistry, and alchemy, was unsuccessful in explaining the nature of matter and its transformations. However, by performing experiments and recording the results, alchemists set the stage for modern chemistry. (Full article...)

The Flammarion woodcut is an enigmatic woodcut by an unknown artist. It is referred to as the "Flammarion woodcut" because its first documented appearance is in page 163 of Camille Flammarion's L'atmosphère: météorologie populaire ("The Atmosphere: Popular Meteorology," Paris, 1888).

The woodcut depicts a man, dressed as a medieval pilgrim and carrying a pilgrim's staff, peering through the sky as if it were a curtain to look at the inner workings of the universe. One of the elements of the cosmic machinery bears a strong resemblance to traditional pictorial representations of the "wheel in the middle of a wheel" described in the visions of the prophet Ezekiel (see Merkabah). The caption in Flammarion's book translates as "A missionary of the Middle Ages tells that he had found the point where the sky and the Earth touched..." The image accompanies a text which reads, in part, "What, then, is this blue sky, which certainly does exist, and which veils from us the stars during the day?" The woodcut is often described as being medieval due to its visual style, its fanciful vision of the world, and to what appears to be a depiction of a flat Earth.

... that the Merton Thesis—an argument connecting Protestant pietism with the rise of experimental science—dates back to Robert K. Merton's 1938 doctoral dissertation, which launched the historical sociology of science?

...that a number of scientific disciplines, such as computer science and seismology, emerged because of military funding?

...that the principle of conservation of energy was formulated independently by at least 12 individuals between 1830 and 1850?

Muhammad al-Qunawi edition of al-Khalili's universal table

Muhammad ibn al-Katib Sinan al-Qunawi (died c. 1524), also known as Muhammad ibn Yusuf, was an Ottoman astronomer and muwaqqit (timekeeper) in the late fifteenth and early sixteenth century. A pioneer of Ottoman astronomy, especially in the field of astronomical instruments and timekeeping, he served as muwaqqit at various mosques, and eventually at the Sublime Porte under Suleiman the Magnificent (r. 1520–1566). He was influenced by earlier Mamluk astronomers, especially Shams al-Din al-Khalili (1320–1380) and Ibn al-Shatir (c. 1304—1375), as well as by the Central Asian Ali al-Qushji and Al-Biruni.

He wrote two treatises on the construction of the astrolabe quadrant (al-rub' al-muqantarat), including Hadiyat al-Muluk ("A Present for Kings") dedicated to Bayezid II (r. 1481–1512). He published a Turkish edition of Al-Khalili's universal tables, and compiled Mizan al-Kawakib ("Balance of the Stars"), containing tables that allow reading the time at night by observing the stars—"the most original Ottoman contribution to astronomical timekeeping by tables" according to historian of astronomy David A. King. In addition to the then commonly used Arabic, he also wrote in Turkish, in order to make his field more accessible throughout the empire. This tradition would be continued by astronomers such as Mustafa ibn Ali al-Muwaqqit. Taha Yasin Arslan writes that al-Qunawi "single-handedly pioneered" the science of timekeeping in the Ottoman Empire. (Full article...)
