41. Mathematical Symbols This symbol for pi was used by the early English mathematicians William Oughtred (1574 1660), Isaac Barrow (1630-1677), and David Gregory (1661-1701) to designate the http://www.roma.unisa.edu.au/07305/symbols.htm

The History of Mathematical Symbols By Douglas Weaver Mathematics Coordinator, Taperoo High School with the assistance of Anthony D. Smith Computing Studies teacher, Taperoo High School. Introduction On the topic of mathematical symbols..... "Every meaningful mathematical statement can also be expressed in plain language. Many plain-language statements of mathematical expressions would fill several pages, while to express them in mathematical notation might take as little as one line. One of the ways to achieve this remarkable compression is to use symbols to stand for statements, instructions and so on." Lancelot Hogben Index The factorial symbol n! The symbols for similar and congruent The symbols for angle and right angle The symbol pi ... APPENDIX - Personalities select here to return to the HoM home page The factorial symbol n! The symbol n!, called factorial n, was introduced in 1808 by Christian Kramp of Strassbourg, who chose it so as to circumvent printing difficulties incurred by the previously used symbol thus illustrated on the right. (Eves p132) The symbol n! for "factorial n", now universally used in algebra, is due to Christian Kramp (1760-1826) of Strassburg, who used it in 1808. (Cajori p341)

45. Faces Of Mathematics: Portraits Of Mathematicians By Photographer Marc Atkins An exhibition of Marc Atkins' blackand-white photography, featuring portaits of mathematicians and information about their research http://www.ma.hw.ac.uk/~ndg/fom.html

FACES OF MATHEMATICS "Faces of Mathematics" penetrates the esoteric world of University mathematics research and presents the human side of this most austere and challenging area of modern science. Focussing on the personalities of twenty influential mathematicians, the exhibition features large-format black and white portraits, taken by the photographer Marc Atkins. Alongside each of the portraits, a text-based display panel conveys the subject's research interests and personal viewpoint on mathematics, and a video loop shows the subject in conversation about their own research and other mathematical ideas. To see a larger portrait image, and to find out more about the individual subjects, click on a small image above. Information on the philosophy and practice behind Faces of Mathematics. Faces of Mathematics has recently been on show at the 2003 conference of the Mathematical Association at The University of East Anglia, and was previously shown at the Highgate Literary and Scientific Institution and the Oxford University Museum of Natural History . You can see some images of the exhibition in Oxford.

46. The Amazing History Of Pi That the ratio of the circumference to the diameter of a circle is constant (namely, pi) has been recognized for as long as we have written records. http://www.ualr.edu/lasmoller/pi.html

Did you know . . .? has a long and interesting history! Ancient history More pi history A novel way to compute pi- The symbol for pi ... For more information That the ratio of the circumference to the diameter of a circle is constant (namely, pi) has been recognized for as long as we have written records. A ratio of 3:1 appears in the following biblical verse: And he made a molten sea, ten cubits from the one brim to the other: it was round all about, and his height was five cubits: and a line of thirty cubits did compass it about. (I Kings 7, 23; II Chronicles 4, 2.) The ancient Babylonians generally calculated the area of a circle by taking 3 times the square of its radius ( =3), but one Old Babylonian tablet (from ca. 1900-1680 BCE) indicates a value of 3.125 for pi. Ancient Egyptians calculated the area of a circle by the following formula (where d is the diameter of the circle): This yields an approximate value of 3.1605 for pi. Beginning with a hexagon, he worked all the way up to a ploygon with 96 sides! Archimedes's method for approximating the value of pi.
