Pierre Duhem
Pierre Maurice Marie Duhem (French: [pjɛʁ mɔʁis maʁi dy.ɛm, – moʁ-] ; 9 June[4] 1861 – 14 September 1916) was a French theoretical physicist who worked on thermodynamics, hydrodynamics, and the theory of elasticity. Duhem was also a historian of science, noted for his work on the European Middle Ages, which is regarded as having created the field of the history of medieval science.[5] As a philosopher of science, he is remembered principally for his views on the indeterminacy of experimental criteria (see Duhem–Quine thesis).

Early life and education[edit]
Duhem completed a Ph.D. in 1888 at Université Paul Sabatier titled Étude historique sur la théorie de l'aimantation par influence.[6]
Theoretical physics[edit]
Among scientists, Duhem is best known today for his work on chemical thermodynamics, and in particular for the Gibbs–Duhem and Duhem–Margules equations. His approach was strongly influenced by the early works of Josiah Willard Gibbs, which Duhem effectively explained and promoted among French scientists. In continuum mechanics, he is also remembered for his contribution to what is now called the Clausius–Duhem inequality.
Duhem was convinced that all physical phenomena, including mechanics, electromagnetism, and chemistry, could be derived from the principles of thermodynamics.[7] Influenced by Macquorn Rankine's "Outlines of the Science of Energetics",[8] Duhem carried out this intellectual project in his Traité de l'Énergétique (1911), but was ultimately unable to reduce electromagnetic phenomena to thermodynamic first principles.
With Ernst Mach, Duhem shared a skepticism about the reality and usefulness of the concept of atoms.[9] He therefore did not follow the statistical mechanics of Maxwell, Boltzmann, and Gibbs, who explained the laws of thermodynamics in terms of the statistical properties of mechanical systems composed of many atoms.
Duhem was an opponent of Albert Einstein's theory of relativity.[10][11] In 1914, Duhem commented that Einstein's relativity theory "has turned physics into a real chaos where logic loses its way and common-sense runs away frightened".[12] In his 1915 book La Science Allemande, he argued strongly against relativity.[11] Duhem stated that the theory of relativity "overthrow[s] all the doctrines in which one has spoken of space, of time, of movement, all the theories of mechanics and of physics".[13]
