Extractions: A date with Pi?! Below are listed the dates of some of the many breakthroughs related to pi over the years 1650 BCE - The earliest known reference to Pi was made on a Middle Kingdom papyrus scroll written by Ahmes the scribe. 1540 CE - Ludolph van Ceulen born. Pi is sometimes called 'die Ludolph Zahl' after Ludolph van Ceulen, the German mathematician who devoted his life to calculating 35 decimals of pi. 1701 - 100 digits of pi were calculated. 1706 - William Jones first give the Greek Letter pi its current mathematical meaning. 1768 - Johann Lambert proved pi is irrational. 1897 - A bill was passed by the State House of Representatives of Indiana, setting pi to equal 9.2376!! 1931 - A man from Cleveland published a book declaring pi to equal exactly 256/81 1975 - Simon Plouffe entered the Guiness Book of Records for reciting 4096 digits of pi from memory. 1995 - Hiroyoki Gotu became the new pi memory champion by reciting 42 000 digits of pi Return to welcome page

Als je dit vaak hebt, dan kan je de muisaanwijzer een staartje geven. Zodra je de muis over de muismat beweegt, zie je niet alleen het pijltje zelf, maar meerdere pijltjes die de echte aan wijzer getrouw volgen. Om de staart te activeren, moet je in het configuratiescherm (Start Instellingen Configuratiescherm) dubbelklikken op het muisicoon. Ga naar het tabblad Beweging en zet de optie Aanwijzerspoor aan.

What Is Algorithmic Number Theory? Earlier in my Dutch journal I had reported that ludolph van ceulen is knownto mathematical history buffs as the 17thcentury fencing instructor who long http://www.math.harvard.edu/~elkies/compnt:.html

NDE] A Mathematician's Apology , 1940) that it has no ``practical'' use at all? Well, a lot has happened since 1940. I got this far in my travel report without saying anything to describe algorithmic number theory is, but some explanation is needed now, not only to explain the NSA's presence but also to put my own talk and the pi celebration in context. Readers already conversant with number theory and its cryptological applications may want to skim through the next three paragraphs. To describe algorithmic number theory, I must first say something about number theory, and I could start with the dry definition: it's the study of whole numbers and related mathematical structures primes, solving equations in rational numbers, that sort of thing. But number theory is unique among modern mathematical disciplines in having a wealth of problems, some extremely hard, that can be stated in terms comprehensible to the non-specialist. So rather than give technical definitions I'll try to suggest the spirit of the subject by giving examples. The canonical example is the problem suggested by Fermat and known misleadingly as ``Fermat's Last Theorem'', in fact proved only a few years ago see this URL for one telling of the story.

Recently the Dibner Library acquired a collection of Acts of the British Parliament and two period newspaper articles relating to the longitude problem and calendar reform. The purchase of the set was made possible with the Special Collections Endowment Fund. The importance of solving the problems of longitude and calendar reform were critical to the history of science and technology and this collection will enhance the research and exhibition values of the Dibner Library's holdings.
