Next Ludolph van Ceulen Two thousand years ago, the ratio between the circumference of a circle and its diameter was taken to be "3". Although the value was close, as time went on efforts were made to refine the ratio to a more precise constant. Greek mathemetician, Archimedes, correctly asserted that it fell between 3 10/70, and 3 10/71. In the computer age, the number has been calculated to the one millionth decimal place, and has been determined to be an irrational number, without a finite definition. Ludolph van Ceulen was born at Hildesheim, Germany, 28 January, 1540. Like many Germans during the Catholic Inquisitions, he emmigrated to The Netherlands. He taught Fencing and Mathematics in Delft until 1594, when he moved to Leiden and opened a Fencing School. In 1600 he was appointed to the Engineering School at Leiden, where he spent the remainder of his life teaching Mathematics

Januar in Hildesheim , † 31. Dezember in Leiden) war ein niederl¤ndischer Mathematiker Ludolph van Ceulen wurde durch die auf 35 Dezimalstellen genaue Berechnung der Kreiszahl π ber¼hmt. Bis ins 19. Jahrhundert bezeichnete man π auch als Ludolphsche Zahl. Sie wurde zu einem eigenst¤ndigen mathematischen Untersuchungsobjekt: die Jagd nach immer mehr Stellen. Er war so stolz auf seine Berechnung, so dass er diese auf seinen Grabstein verewigte. Van Ceulens Berechnungen Archimedes ging bei seinen Forschungen zur Kreiszahl von regelm¤Ÿigen Vielecken aus, die einem Kreis mit dem Durchmesser d=1 einbeschrieben bzw. umschrieben sind. Je h¶her die Eckenzahl dieser Vielecke ist, umso mehr n¤hern sie sich von innen und auŸen dem Kreis an. Archimedes begann beim regelm¤Ÿigen Sechseck, setzte mit dem Zw¶lfeck fort, dann mit dem 24-, 48-, 96-Eck usw. Jedesmal ist die Seitenl¤nge s n des n-Ecks neu zu berechnen.

He held a number of posts not only as a teacher of mathematics but also as a fencing teacher. He taught fencing and mathematics in Delft, then in 1594, opened a fencing school in Leiden. In 1600 he was appointed to the Engineering School in Leiden. For the last ten years of his life he taught arithmetic, surveying and fortification in the engineering school. Van Ceulen is famed for his calculation of p to 35 places which he did using polygons with 2 sides. He spent most of his life doing this and it is fitting that the 35 places of p are engraved on his tombstone. In Germany p was called the Ludolphine number for a long time.
