The history of science during the Enlightenment traces developments in science and technology as Enlightenment ideas and ideals were being disseminated across Europe and North America. Generally, the period spans from the final days of the 16th- and 17th-century Scientific Revolution until roughly the 19th century, after the French Revolution (1789) and the Napoleonic era (1799–1815). The scientific revolution saw the creation of the first scientific societies, the rise of Copernicanism, and the displacement of Aristotelian natural philosophy and Galen's ancient medical doctrine. By the 18th century, scientific authority began to displace religious authority, and the disciplines of alchemy and astrology lost scientific credibility.
While the Enlightenment cannot be pigeonholed into a specific doctrine or set of dogmas, science came to play a leading role in Enlightenment discourse and thought. Many Enlightenment writers and thinkers had backgrounds in the sciences and associated scientific advancement with the overthrow of religion and traditional authority in favour of the development of free speech and thought. Broadly speaking, Enlightenment science greatly valued empiricism and rational thought, and was embedded with the Enlightenment ideal of advancement and progress. As with most Enlightenment views, the benefits of science were not seen universally; Jean-Jacques Rousseau criticized the sciences for distancing man from nature and not operating to make people happier.
Science during the Enlightenment was dominated by scientific societies and academies, which had largely replaced universities as centres of scientific research and development. Societies and academies were also the backbone of the maturation of the scientific profession. Another important development was the popularization of science among an increasingly literate population. Philosophes introduced the public to many scientific theories, most notably through the Encyclopédie and the popularization of Newtonianism by Voltaire as well as by Émilie du Châtelet, the French translator of Newton's Philosophiæ Naturalis Principia Mathematica. Some historians have marked the 18th century as a drab period in the history of science; however, the century saw significant advancements in the practice of medicine, mathematics, and physics; the development of biological taxonomy; a new understanding of magnetism and electricity; and the maturation of chemistry as a discipline, which established the foundations of modern chemistry.

== Universities ==

The number of universities in Paris remained relatively constant throughout the 18th century. Europe had about 105 universities and colleges by 1700. North America had 44, including the newly founded Harvard and Yale. The number of university students remained roughly the same throughout the Enlightenment in most Western nations, excluding Britain, where the number of institutions and students increased. University students were generally males from affluent families, seeking a career in either medicine, law, or the Church. The universities themselves existed primarily to educate future physicians, lawyers and members of the clergy.
The study of science under the heading of natural philosophy was divided into physics and a conglomerate grouping of chemistry and natural history, which included anatomy, biology, geology, mineralogy, and zoology.  Most European universities taught a Cartesian form of mechanical philosophy in the early 18th century, and only slowly adopted Newtonianism in the mid-18th century. A notable exception were universities in Spain, which under the influence of Catholicism focused almost entirely on Aristotelian natural philosophy until the mid-18th century; they were among the last universities to do so. Another exception occurred in the universities of Germany and Scandinavia, where University of Halle professor Christian Wolff taught a form of Cartesianism modified by Leibnizian physics.

Before the 18th century, science courses were taught almost exclusively through formal lectures. The structure of courses began to change in the first decades of the 18th century, when physical demonstrations were added to lectures. Pierre Polinière and Jacques Rohault were among the first individuals to provide demonstrations of physical principles in the classroom. Experiments ranged from swinging a bucket of water at the end of a rope, demonstrating that centrifugal force would hold the water in the bucket, to more impressive experiments involving the use of an air-pump. One particularly dramatic air-pump demonstration involved placing an apple inside the glass receiver of the air-pump, and removing air until the resulting vacuum caused the apple to explode. Polinière's demonstrations were so impressive that he was granted an invitation to present his course to Louis XV in 1722.
Some attempts at reforming the structure of the science curriculum were made during the 18th century and the first decades of the 19th century. Beginning around 1745, the Hats party in Sweden made propositions to reform the university system by separating natural philosophy into two separate faculties of physics and mathematics. The propositions were never put into action, but they represent the growing calls for institutional reform in the later part of the 18th century. In 1777, the study of arts at Kraków and Vilna in Poland was divided into the two new faculties of moral philosophy and physics. However, the reform did not survive beyond 1795 and the Third Partition. During the French Revolution, all colleges and universities in France were abolished and reformed in 1808 under the single institution of the Université imperiale. The Université divided the arts and sciences into separate faculties, something that had never before been done before in Europe. The United Kingdom of the Netherlands employed the same system in 1815. However, the other countries of Europe did not adopt a similar division of the faculties until the mid-19th century.
