, de Descartes et de Gauss Théorème de Wantzel Abel Un nombre constructible est donc est constructible ! Conséquence 1 : la duplication du cube est impossible Selon le théorème de wantzel, n'est pas constructible et par suite et la duplication du cube est impossible Q et non constructible. Conséquence 2 : la quadrature du cercle est impossible : quadrature p est transcendant Lindemann p . Il faut donc construire p Quadrature approchée du cercle selon Dinostrate Conséquence 3 : la trisection de l'angle est impossible : trisection de l'angle x : par projection, cos x = OH et la formule : x - 3cos x montre que cos Il est clair que les angles de 180° et 90° sont trisectables; d'ailleurs si x est trisectable, son double (par report) et sa moitié (bisection) le sont aussi Ainsi 45° est trisectable : trisecter 90° : on obtient 30°; bissecter 30° : on obtient 15°. Q p Or, il est facile de prouver ci-dessous Gauss Noter que les mathématiciens arabes avaient déjà soupçonné l'impossibilité de la trisection géométrique de l'angle en ramenant le problème, comme le fit ultérieurement Al-Biruni : N = b Donc b est pair. Posons b = 2c. Il vient a

Haitian Math Whiz May Have Unraveled Age-old Geometry Mystery HAITI PROGRES ( http://www.haiti-progres.com), October 9 - 15, 2002 Vol. 20, No. 30 by Kim Ives PHOTO: : Leon Romain has devised a theorem for trisecting any angle, one of geometry's great puzzles. If he is right, it could change your life. So far, nobody has proved him wrong Around 450 B.C., the Greek mathematician, Hippias of Ellis, began searching for a way to trisect an angle. Over 2000 years later, in 1837, a French mathematician named Pierre Wantzel proclaimed that it was impossible to trisect an angle using just a compass and a straightedge, the only tools allowed in geometric construction. But now, at the dawn of the twenty-first century, a Haitian computer program designer, Leon Romain, claims he has proven, with a "missing theorem," that it is possible to trisect an angle with those simple tools, disproving Wantzel's assertion and exploding centuries of mathematical gospel. "This discovery shows us that the notions that every mathematician has held for the past 200 years as absolute certainty are actually false," Romain told Haiti Progres. "The mathematical and even philosophical ramifications are huge."

Mathematician Report Index Below is a list of mathematicians. You may choose from this list or report on a mathematician not listed here. In either case, you must discuss with me the mathematician you have chosen prior to starting your report. No two students may write a report on the same mathematician. I would advise you to go to the library before choosing your topic as there might not be much information on the mathematician you have chosen. Also, you should determine the topic early in the term so that you can "lock-in" your report topic!! The report must include: 1. The name of the mathematician. 2. The years the mathematician was alive. 3. A biography. 4. The mathematician's major contribution(s) to mathematics and an explanation of the importance. 5. A historical perspective during the time the mathematician was alive. Some suggestions on the historical perspective might be: (a) Any wars etc. (b) Scientific breakthroughs of the time (c) Major discoveries of the time (d) How did this mathematician change history etc.
