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.

A concise description of FLANDERS History Painters Musicians - Scientists - Links Comments and suggestions Scientists Jan Yperman (also Johannes, Jehan, Jean, John, Ypres c. 1270 - c.1330) This "Father of surgery" attended courses in Bologna and Paris. He was appointed surgeon at the city of Ypres in 1304. He wrote, in Dutch, two important treatises on medecine: "Medicine boeck" (copy Leiden 1351) and "Cyrurgie boeck" (c. 1328). Regnier Gemma Frisius (Dokkum, Holland 1508 - Leuven, 1555) He was a native of Friesland, a coastal province in the northern Netherlands, which explains his nickname of Frisius. He was educated at the University of Louvain, receiving a medical degree. He became the leading theoretical mathematician in the Low Countries and became professor of medicine and mathematics at the University of Louvain. He was also a practicing physician in Louvain. He wrote De Principiis Astronomiae Cosmographicae (Leuven, 1530). Chapter 19 of this work describes, for the first time, how the longitude of a place may be found using a clock to determine the difference in local and absolute times. In a second edition of the work three years later he added some notes about finding the longitude at sea, the first time anyone had attacked the problem. It is worth noting that although there were many methods of finding longitude proposed in the 250 years following Gemma Frisius's work, ultimately the methods he proposed were to become the solution to finding the longitude at sea.
