Roger Balian (born 18 January 1933) is a French-Armenian physicist who has worked on quantum field theory, quantum thermodynamics, and theory of measurement.
Balian is a member of French Académie des sciences (Academy of Sciences). His important work includes the Balian-Low theorem. He teaches statistical physics at the École Polytechnique.
Jean-Charles Adolphe Alphand (French pronunciation: [ʒɑ̃ ʃaʁl adɔlf alfɑ̃]; 26 October 1817 – 6 December 1891) was a French engineer of the Corps of Bridges and Roads. As a close associate of Baron Haussmann and later as Director of Public Works at Paris City Hall from 1871, he was instrumental in the large-scale renovation of Paris in the second half of the 19th century. In 1889, Alphand was elevated to the rank of Grand Cross of the Legion of Honour. In 1891, shortly before his death, he succeeded Haussmann as a member of the Académie des Beaux-Arts.
Gérard Araud (born 20 February 1953) is a retired French diplomat who served as Ambassador of France to the United States from 2014 to 2019. He previously served as Director General for Political and Security Affairs of the Ministry of Foreign Affairs (2006–2009) and France's permanent representative to the United Nations (2009–2014).
Nicolas Léonard Sadi Carnot (French pronunciation: [nikɔla leɔnaʁ sadi kaʁno]; 1 June 1796 – 24 August 1832) was a French mechanical engineer in the French Army, military scientist and physicist, often described as the "father of thermodynamics". He published only one book, the Reflections on the Motive Power of Fire (Paris, 1824), in which he expressed the first successful theory of the maximum efficiency of heat engines and laid the foundations of the new discipline: thermodynamics. Carnot's work attracted little attention during his lifetime, but it was later used by Rudolf Clausius and Lord Kelvin to formalize the second law of thermodynamics and define the concept of entropy. Driven by purely technical concerns, such as improving the performance of the steam engine, Sadi Carnot's theoretical work laid important foundations for modern science as well as technologies such as the automobile and jet engine.
His father Lazare Carnot was an eminent mathematician, military engineer, and leader of the French Revolutionary Army.
Paul Hermelin (born April 30, 1952) is a French businessman who is the chairman of Capgemini.
Gabriel Auguste Daubrée MIF FRS FRSE (25 June 1814 – 29 May 1896) was a French geologist, best known for applying experimental methods to structural geology. He served as the director of the École des Mines as well as the president of the French Academy of Sciences.
Dominique Senequier (born 1953) is a French businesswoman. She is president of Ardian (formerly Axa Private Equity), a private equity firm she founded in 1996.
Commandant Caroline Aigle (French pronunciation: [kaʁɔlin ɛɡl] ) (12 September 1974 – 21 August 2007) was a French aviator who achieved a historical first when, at the age of 25, she became the first woman fighter pilot in the French Air Force. Her promising military career was cut short by death from cancer seven years later. She was posthumously awarded the Médaille de l'Aéronautique (Aeronautics Medal).
Henry Louis Le Chatelier (French pronunciation: [ɑ̃ʁi lwi lə ʃɑtəlje]; 8 October 1850 – 17 September 1936) was a French chemist of the late 19th and early 20th centuries. He devised Le Chatelier's principle, used by chemists and chemical engineers to predict the effect a changing condition has on a system in chemical equilibrium.
Hervé Auguste Étienne Albans Faye ((1814-10-01)1 October 1814 – (1902-07-04)4 July 1902) was a French astronomer, born at Saint-Benoît-du-Sault (Indre) and educated at the École Polytechnique, which he left in 1834, before completing his course, to accept a position in the Paris Observatory to which he had been appointed on the recommendation of M. Arago. It was during his time at the École Polytechnique that he developed his interest in astronomy.He studied comets, and discovered the periodic comet 4P/Faye on 22 November 1843. His discovery of "Faye's Comet" attracted worldwide attention, and won him the 1844 Lalande Prize and a membership in the French Academy of Sciences. In 1848 he became an instructor in geodesy at the Polytechnique, and in 1854 rector of the academy at Nancy and professor of astronomy in the faculty of science there. Other promotions followed in succeeding decades. He became Minister of Public Instruction in the Rochebouet cabinet in 1877, a position which he held only briefly.
Faye served as the President of the Société Astronomique de France (SAF), the French astronomical society, from 1889 to 1891. He also served as president of the International Geodetic Association from 1892 to 1902.His work covered the entire field of astronomical investigation. It comprised the determination of comet periods, the measurement of parallaxes, and the study of stellar and planetary movements. He also studied the physics of the sun. He advanced several original theories on the nature and form of comets, meteors, the aurora borealis, and the sun.
