Note that the pronunciation of this letter in Greek is like the English word 'Pea' (the same way they say the name of the letter 'P') or perhaps like the p and i in the word 'Pit.' But it's NEVER pronounced like the English word 'Pie' in Greece! To create that type of sound, Greek could use the diphthong 'ai' (it means two vowels together; like the 'oi' in the English word 'oil'); so, 'pai' in Greek would sound like 'pie' in English.

Extractions: Home Humor and Games Code Music ... Search Suppose the polygons have 2 n sides. If the central angle of the polygon is 2 then the length of each side of the inner polygon can be shown to be the sine of the angle , and the length of each side of the outer polygon is the tangent of the angle . Using the half-angle identities for the sine and tangent, it is not hard to derive iterative formulas for the polygon perimeters. It turns out that, given the inner perimeter I n and the outer perimeter O n I n+1 is the geometric mean of I n and O n , and O n+1 is the harmonic mean of I n and O n This was stunning mathematics; Archimedes did not have a very usable number system to work with and did not have the tools of modern trigonometry. He also used a limiting process that would find echoes centuries later in the work of Leibniz and Newton on the integral calculus. It took decades for him to do, but he managed to compute 35 correct digits. His method was also the same method of exhaustion used by Archimedes, though instead of using polygons with only a few hundred sides, van Ceulen had used a 2 -gon for his approximation. It would take the development of the calculus before more efficient methods would be discovered.

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 what 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.

Extractions: Ludolph van Ceulen (28 January 1540 in Hildesheim, Germany - 31 December 1610 in Leiden, The Netherlands) was a German mathematician who emigrated to the Netherlands. He was appointed the first professor of mathematics at the university of Leiden in 1600. Ludolph van Ceulen spent a major part of his life calculating the numerical value of the mathematical constant , using essentially the same methods as those employed by Archimedes some 1800 years earlier. He published a 20-decimal value in his 1596 book Van de Cirkel ('On the Circle'), later expanding this to 35 decimals. After his death, the 'Ludolphine number' was engraved on his tombstone in Leiden. The tombstone was later lost, but has been restored in the year 2000.
