FERMAT - THE PRINCE OF MATHEMATICS

The greatest mathematician of the 17th century was Fermat (1601-1665). This of course leaves Newton out of consideration. But it can be argued that Fermat was at least Newton's equal as a pure mathematician, and anyhow nearly a third of Newton's life fell into the eighteenth century, whereas the whole of Fermat's was lived out in the seventeenth. Newton appears, to have regarded his mathematics principally as an instrument for scientific exploration and put his main effort on the latter. Fermat on the other hand was more strongly attracted to pure mathematics although he also did notable work in the applications of mathematics to science, particularly optics. Fermat's life was quiet, laborious, and uneventful, but he got a tremendous lot out of it. The essential facts of his peaceful career are quickly told. Pierre Fermat was born at Beaurnont-de-Lomagne, France, in 1601. His earliest education was received at home in his native town; his later studies, in preparation for the magistracy, were continued at Toulouse. As Fermat lived temperately and quietly all his life, avoiding profitless disputes, singularly little appears to have survived of his career as a student. That it must have been brilliant will be evident from the achievements and accomplishments of his maturity: no man without a solid foundation of exact scholarship could have been the classicist and litterateur that. Fermat became. His marvelous work in the theory of numbers and in mathematics generally cannot be traced to his schooling; for the fields in which he did his greatest work, not having been opened up while he was a student, could scarcely have been suggested by his studies. His story is his work, his recreation, rather-done for the love for it, and the best of it is so simple that any schoolboy of normal intelligence can understand its nature and appreciate its beauty. The work of this prince of mathematical analysis has had an irresistible appeal to amateurs of mathematics in all civilized countries during the past three centuries.
