Branch of Science Mathematicians Nationality French ... Barile Desargues, Girard (1593-1662) This entry contributed by Margherita Barile French mathematician, considered as the founder of projective geometry There seems not to be much reliable information on his life and work, most of what we know comes from indirect sources. Desargues used to write down his ideas in form of brief sketches, none of which was intended for publication, and many of which went lost. He made no effort to make them understandable to potential readers: he used "microscopic characters" (Poudra 1864), an exceedingly concise style, and expressed himself in a language of his own. His only extensive work, , has survived through a transcription by Philippe de la Hire , who felt compelled to add a glossary of terms. There we learn that "navel" and "burning point" mean "focus," that "roll" denotes a cylindric or conic solid, whereas two different words, "column" and "horn," are used for the cylindric and the conic surface. The conic sections themselves are referred to as "the border of a roll cut." Other manuscripts were edited by Abraham Bosse, a student of Desargues who was also a sculptor, and profited from his teacher's attention towards the applications of geometry to art and architecture. Desargues wrote treatises on perspective, sundials, on the cutting of stones, on the mechanical applications of epicycloids, and he also designed buildings. He probably contributed to the construction of the dam in La Rochelle, by order of Cardinal Richelieu, with whom he was familiar, as we are told by

Return to The Worlds of David Darling INDEX LATEST NEWS ARCHIVE ... Z entire Web this site Desargues, Girard (1591-1661) A French mathematician who is regarded as the chief founder of perspective geometry. His 12-page treatise La perspective (636) consists of a single worked example in which Desargues sets out a method for constructing a perspective image without using any point lying outside the picture field. He considers the representation in the picture of plane of lines that meet at a point and also of lines that are parallel to each another. In the last paragraph of the work he considers the problem of finding the perspective image of a conic section . Three years later, he wrote his treatise on projective geometry Brouillon project d'une atteinte aux evenemens des rencontres du cone avec un plan . The first part of this deals with the properties of sets of straight lines meeting at a point and of ranges of points lying on a straight line. In the second part, the properties of conics are investigated in terms of properties of ranges of points on straight lines and the modern term "point at infinity" appears for the first time. Desargues shows that he has completely grasped the connection between conics and perspective; in fact he treats the fact that any conic can be projected into any other conic as obvious. Given such innovative work it may seem surprising that the subject didn't develop rapidly in the following years. That it didn't may be partly due to mathematicians failing to recognize the power of what had been put forward. On the other hand the algebraic approach to geometry put forward by René

His family (on both his mother's and his father's side) had been very rich for several generations and had supplied lawyers and judges to the Parlement in Paris as well as to that in Lyon (then the second most important city in France). Desargues seems to have made several extended visits to Paris in connection with a lawsuit for the recovery of a huge debt. Despite this loss, the family still owned several large houses in Lyon, a manor house (and its estate) at the nearby village of Vourles, and a small chateau surrounded by the best vineyards in the vicinity. It is thus clear that Desargues had every opportunity of acquiring a good education, could afford to buy what books he chose, and had leisure to indulge in whatever pursuits he might enjoy. In his later years, these seem to have included designing an elaborate spiral staircase, and an ingenious new form of pump, but the most important of Desargues' interests was Geometry. He invented a new, non-Greek way of doing geometry, now called 'projective' or 'modern' geometry. As a mathematician he was very good indeed: highly original and completely rigorous. He is, however, far from lucid in his mathematical style.

Pre-Einstein famous mathematicians. Stu Savory, 2004. If you ask people these days to name a famous mathematician, surveys show the most popular answer to be Albert Einstein . Einstein himself used to like to quote Sir Isaac Newton's famous humble line "If I have seen further than other men, it is by standing on the shoulders of giants." So I asked myself, who were these giants, i.e. famous pre-Einstein mathematicians. Here's the list of the top 100 or so, sorted chronologically. How many do you know? That means you can state what they were famous for, off the cuff, no googling! If you score below 30 you need to do some revision :-) Ahmes c. 1650 B C Pythagoras c.540 BC Hippocrates c.440 BC (that's Hippocrates of Chios, NOT the physician who lived around the same time).
