Edme Mariotte - Work

Work

Mariotte is best known for his recognition in 1676 of Boyle's Law about the inverse relationship of volume and pressures in gases. In 1660 he had discovered the eye's blind spot. A small coin placed in the blind spot disappears from vision, a seemingly magical event that amazed the French royal court when first presented by Mariotte. He was one of the first members of the French Academy of Sciences founded at Paris in 1666. The first volume of the Histoire et mémoires de l'Académie (1733) contains many original papers by him upon a great variety of physical subjects, such as the motion of fluids, the nature of colour, the notes of the trumpet, the barometer, the fall of bodies, the recoil of guns, the freezing of water etc. His Essais de physique, four in number, of which the first three were published at Paris between 1676 and 1679, are his most important works, and form, together with a Traité de la percussion des corps, the first volume of the Œuvres de Mariotte (2 vols., Leiden, 1717). The second of these essays (De la nature de l'air) contains the statement of the law that the volume of a gas varies inversely as the pressure, which, though very generally called by the name of Mariotte, had been discovered in 1660 by Robert Boyle. The fourth essay is a systematic treatment of the nature of colour, with a description of many curious experiments and a discussion of the rainbow, halos, parhelia, diffraction, and the more purely physiological phenomena of colour. He also made a significant contribution to the development of aerodynamic theory with the statement that aerodynamic resistance varies as the square of the velocity. The discovery of the blind spot is noted in a short paper in the second volume of his collected works.
