His major scientific achievements were the establishment of the physics of vacuums, the discovery of an experimental method for clearly demonstrating electrostatic repulsion, and his advocacy of the reality of "action at a distance" and of "absolute space".
Document 5: Dominique Kalifa: Dominique Kalifa is a French historian, professor at the University of Paris 1 Pantheon-Sorbonne, where he is director of the Centre of 19th Century History and member of the Institut Universitaire de France. A student of Michelle Perrot, he specialises in the history of crime, transgression, social control, and mass culture in 19th and early 20th France and Europe. He also teaches at the Institut d'Etudes Politiques de Paris (Sciences Po) from 2008 and reviews for the French newspaper "Libération". His last book was devoted to the underworld and its role in the Western imagination. He is currently working on a new project about the concept of ""Belle Epoque"" and the ways 20th century France has represented the turn of the century.
Document 6: Sébastien Basson: Sébastien Basson, Latinized as Sebastianus Basso, was a French physician and natural philosopher of the beginning of the seventeenth century. He was an early theorist of a matter theory based on both atoms and compounds. His natural philosophy draws on several currents of thought, including Italian Renaissance naturalism, alchemy and Calvinist theology. Basson was an atomist, who, independently from Isaac Beeckman, formed the concept of "molecule".
Document 7: Michèle Le Dœuff: Michèle Le Dœuff (] ; born 1948) is a French philosopher with a scholarly interest in the philosophy of Francis Bacon, and Sir Thomas More's utopianism. She questions the boundaries of philosophy, while insisting upon philosophy's importance (for example, in "Ants and Women"). She is critical of professional philosophers' neglectful attitude to science, and argues that disputes within sciences are often epistemological (that is, properly philosophical). In "Hipparchia's Choice" (1989) she questions philosophy's pretensions to being a unique practice which achieves a pure clarity: philosophy is inevitably shaped by language, metaphor, and power relations. According to Le Dœuff feminists make a special contribution. Their critique of gender categories in philosophy, science, and the humanities is empirical, philosophical, political, and interdisciplinary. Feminists see clearly how discourses are elevated to the status of 'philosophical' by a process in which social power is involved.
Document 8: Renaissance philosophy: The designation "Renaissance philosophy" is used by scholars of intellectual history to refer to the thought of the period running in Europe roughly between 1355 and 1650 (the dates shift forward for central and northern Europe and for areas such as Spanish America, India, Japan, and China under European influence). It therefore overlaps both with late medieval philosophy, which in the fourteenth and fifteenth centuries was influenced by notable figures such as Albert the Great, Thomas Aquinas, William of Ockham, and Marsilius of Padua, and early modern philosophy, which conventionally starts with René Descartes and his publication of the "Discourse on Method" in 1637. Philosophers usually divide the period less finely, jumping from medieval to early modern philosophy, on the assumption that no radical shifts in perspective took place in the centuries immediately before Descartes. Intellectual historians, however, take into considerations factors such as sources, approaches, audience, language, and literary genres in addition to ideas. This article reviews both the changes in context and content of Renaissance philosophy and its remarkable continuities with the past.
Document 9: Galileo Galilei: Galileo Galilei (] ; 15 February 1564 – 8 January 1642) was an Italian polymath: astronomer, physicist, engineer, philosopher, and mathematician. He has been called the "father of observational astronomy", the "father of modern physics", the "father of the scientific method", and the "father of science". Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of pendulums and "hydrostatic balances", inventing the thermoscope and various military compasses, and using the telescope (a Dutch optical instrument) for scientific observations of celestial objects.
Document 10: Robert Boyle: Robert William Boyle {'1': ", '2': ", '3': ", '4': "} (25 January 1627 – 31 December 1691) was an Anglo-Irish natural philosopher, chemist, physicist and inventor born in Lismore, County Waterford, Ireland. Boyle is largely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry, and one of the pioneers of modern experimental scientific method. He is best known for Boyle's law, which describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system. Among his works, "The Sceptical Chymist" is seen as a cornerstone book in the field of chemistry. He was a devout and pious Anglican and is noted for his writings in theology.
Document 11: Blaise Pascal: Blaise Pascal ( ; ] ; 19 June 1623 – 19 August 1662) was a French mathematician, physicist, inventor, writer and Catholic theologian. He was a child prodigy who was educated by his father, a tax collector in Rouen. Pascal's earliest work was in the natural and applied sciences where he made important contributions to the study of fluids, and clarified the concepts of pressure and vacuum by generalising the work of Evangelista Torricelli. Pascal also wrote in defence of the scientific method.
Document 12: Oleg Khoma: Oleg Khoma (born October 30, 1966) is Ukrainian historian of European philosophy, researcher, translator and commentator on 17th- and 20th-century French philosophy. Researcher of Blaise Pascal, Rene Descartes and Nicolas Malebranche.
Document 13: Alexandre Kojève: Alexandre Kojève (] ; 28 April 1902 – 4 June 1968) was a Russian-born French philosopher and statesman whose philosophical seminars had an immense influence on 20th-century French philosophy, particularly via his integration of Hegelian concepts into twentieth century continental philosophy. As a statesman in the French government, he was instrumental in the creation of the European Union. Kojève was a close friend of, and was in lifelong philosophical dialogue with, Leo Strauss.
Document 14: Daniel Bernoulli: Daniel Bernoulli FRS ( ; ] ; 8 February 1700 – 17 March 1782) was a Swiss mathematician and physicist and was one of the many prominent mathematicians in the Bernoulli family. He is particularly remembered for his applications of mathematics to mechanics, especially fluid mechanics, and for his pioneering work in probability and statistics. His name is commemorated in the Bernoulli's principle, a particular example of the conservation of energy, which describes the mathematics of the mechanism underlying the operation of two important technologies of the 20th century: the carburetor and the airplane wing.
