Upon his return to France he was active primarily as an artist. He formed a friendship with Abraham Bosse, Desargues last disciple, who asked La Hire to solve a problem in stonecutting. In 1673 La Hire published Nouvelle methode en géometrie pour les sections des superficies coniques et cylindriques from his research in constructing conic sections. Twelve years later he published a much more extensive work, Sectiones conicae, through which Desargues' projective geometry became known.

Username: Password: Sites for teachers Sites for parents Awards Interactive Activities ... Sites for parents La Hire's Theorem: What Is It About? A Mathematical Droodle Explanation Alexander Bogomolny La Hire's Theorem The applet suggests the following theorem: If point A lies on the polar of point B, then point B lies on the polar of A. The theorem bears the name of Philippe de La Hire , a French artist, architect and mathematician born in the 17 th century. Proof By definition , the polar of B is perpendicular to OB, where O is the center of the circle of reference at the inverse image C of B. Therefore, where R is the radius of the circle. Assume point A lies on polar of point B. Then AC is perpendicular OB. Let D lie on OA with BD perpendicular to the latter. Triangles OAC and OBD are similar (they are both right and share an angle at O.) From here we obtain a proportion OA/OB = OC/OD, which can also be written as , so that D is the inverse image of A and BD is its polar, which proves the theorem. Note that the proof works in all cases, except where the three points O, A, and B are collinear. The polars of A and B are then parallel, the triangles OAC and OBD degenerate into straight line segments, and the proof fails. But then obviously A coincides with C, and (1) still holds. In this case, A and C are just inverse images of each other. Poles and Polars Brianchon's Theorem Complete Quadrilateral Harmonic Ratio ... Inversion La Hire's Theorem La Hire's Theorem, a Variant

Jean Le Fèvre Born: 9 April 1652 in Lisieux, France Died: 1706 in Paris, France Jean Le Fèvre is thought to have started work as a weaver. We know nothing of the first thirty years of Le Fèvre's life but some biographers suggest that he came from a humble background (which is almost certain to be true). The first definite mention of him in the scientific record is as a friend of an amateur astronomer by the name of Father Pierre. Father Pierre was Professor of rhetoric at the Collège de Lisieux in Paris and as such he was a colleague of Jean Picard and de La Hire. Picard needed help with carrying out calculations for his work Connaissances des temps and looked for an assistant. Father Pierre recommended his friend Le Fèvre to Picard as a possible assistant and, after Picard had tested Le Fèvre's abilities, he employed him to assist in the production of Connaissances des temps. Le Fèvre thus became an associate of Picard and de La Hire, and these two recommended him for membership of the Académie des Sciences shortly after this. Indeed Le Fèvre was elected to membership and began work with Picard on calculating astronomical tables. In October 1682 Jean Picard died. Le Fèvre continued with the task he had been set of calculating the tables, and he published Connaissances des temps during the period 1685 to 1701. There is some evidence that in fact he may have published an earlier edition during 1682 to 1684 but this is not certain. He also appears to have assisted de La Hire with the surveys of France that he was carrying out.

He wrote on graphical methods, 1673; on the conic sections, 1685; a treatise on epicycloids, 1694; one on roulettes, 1702; and, lastly, another on conchoids, 1708. His works on conic sections and epicycloids were founded on the teaching of Desargues , whose favourite pupil he was. He also translated the essay of Moschopulus on magic squares , and collected many of the theorems on them which were previously known; this was published in 1705. He also published a set of astronomical tables in 1702. This text incorporates public domain material from Rouse History of Mathematics http://www.maths.tcd.ie/pub/HistMath/People/RBallIndex.html
