Question: Who is a French scholar that specialized in Physics and astronomy?
Context: Alfred Charles Auguste Foucher (1865–1952), a French scholar, identified the Buddha image as having Greek origins.  He has been called the "father of Gandhara studies", and is a much cited scholar on ancient Buddhism in northwest Indian subcontinent and the Hindu Kush region. Lucien Jerphagnon (7 September 1921 – 16 September 2011) was a French scholar, historian and philosopher specialized in Greek and Roman philosophy. Alain Reza Yavari (December 15, 1949 – November 24, 2015) was a French scholar in the fields of chemical and physical metallurgy, with a focus on bulk metallic glasses.  His transdisciplinary approach across physics and chemistry led to remarkable innovations that contributed to significant breakthroughs in both fundamental and applied material sciences. Pierre-Simon, marquis de Laplace ( ; ] ; 23 March 1749 – 5 March 1827) was an influential French scholar whose work was important to the development of mathematics, statistics, physics and astronomy.  He summarised and extended the work of his predecessors in his five-volume "Mécanique Céleste" ("Celestial Mechanics") (1799–1825).  This work translated the geometric study of classical mechanics to one based on calculus, opening up a broader range of problems.  In statistics, the Bayesian interpretation of probability was developed mainly by Laplace. Joseph Ivor Silk FRS (born 3 December 1942) is a British astrophysicist.  He was the Savilian Chair of Astronomy at the University of Oxford from 1999 to September 2011.  He was educated at Tottenham County School (1954–1960) and went on to study Mathematics at the University of Cambridge (1960–1963).  He gained his PhD in Astronomy from Harvard in 1968.  Silk took up his first post at Berkeley in 1970, and the Chair in Astronomy in 1978.  Following a career of nearly 30 years there, Silk returned to the UK in 1999 to take up the Savilian Chair at the University of Oxford.  He is currently Professor of Physics at the Institut d'astrophysique de Paris, Université Pierre et Marie Curie, Homewood Professor of Physics and Astronomy at Johns Hopkins University (since in 2010), and Professor of Astronomy at Gresham College since 2015. Paul Collomp (15 Decembre 1885 – 25 November 1943) was a French scholar specialized in the history of Ptolemaic Kingdom.  He was shot by the Gestapo during a raid against the University of Strasbourg pulled back to Clermont-Ferrand. In physics and astronomy, Euler's three-body problem is to solve for the motion of a particle that is acted upon by the gravitational field of two other point masses that are fixed in space.  This problem is exactly solvable, and yields an approximate solution for particles moving in the gravitational fields of prolate and oblate spheroids.  This problem is named after Leonhard Euler, who discussed it in memoirs published in 1760.  Important extensions and analyses were contributed subsequently by Lagrange, Liouville, Laplace, Jacobi, Darboux, Le Verrier, Velde, Hamilton, Poincaré, Birkhoff and E. T. Whittaker, among others. Firmin Abauzit (November 11, 1679March 20, 1767) was a French scholar who worked on physics, theology and philosophy, and served as librarian in Geneva (Switzerland) during his final 40 years.  Abauzit is also notable for proofreading or correcting the writings of Isaac Newton and other scholars. The New Chronology is a pseudohistorical theory which argues that the conventional chronology of Middle Eastern and European history is fundamentally flawed, and that events attributed to the civilizations of the Roman Empire, Ancient Greece and Ancient Egypt actually occurred during the Middle Ages, more than a thousand years later.  The central concepts of the New Chronology are derived from the ideas of Russian scholar Nikolai Morozov (1854–1946), although work by French scholar Jean Hardouin (1646–1729) can be viewed as an earlier predecessor.  However, the New Chronology is most commonly associated with Russian mathematician Anatoly Fomenko (born 1945), although published works on the subject are actually a collaboration between Fomenko and several other mathematicians.  The concept is most fully explained in "History: Fiction or Science?" , originally published in Russian. Henri Justel (1620–1693) was a French scholar and royal administrator, and also a bibliophile and librarian.  He is known also as Henry Justel and Henricus Justellus.  He was son of the scholar Christophe Justel.
