 | | Van Ceulen computed pi to 20 decimal places, and later, using Archimedes method (to which he added devices to speed things up) to 33 and ultimately to 35 places. |
 | | Van Ceulen formed friendships with powerful figures in the intellectual and scientific community of the Netherlands, including Jan Cornets de Groot, Stevin, and Adrien Van Roomen. |
 | | In the late 80's there was a lively exchange of pamphlets in the Netherlands on the value of pi--which involved, in addition to van Ceulen, Simon van der Eycke, Coignet, Stevin, and others. |
