    How many digits of pi do you have memorized?

    Well, if you spell it with the Hebrew character, there's only one 'digit'. Using the English spelling of "pi" gives us two 'digits'. So, I've memorized all of them! :) John

      3.14159265358 Which is technically wrong, because rounded it should be 3.14159265359 Oh well. I don't need Pi with that resolution anymore. And would I ever, I'd probably download one of those text files available on some math websites with a gazillion digits and use that. :) 3.14 works for most practical purposes in the home, garden, private workshop etc. :) -- You can all bite my shiny metal ass!

We mostly write stuff out as multiples of π and pray the symbols will cancel out. I do recall having to memorizes pages and pages of logarithms in high school, but fortunately college and the slide rule put an end to that folly.

          There's a nice mnemotechnical technique for recalling a lot of digits of pi: How I want a drink, alcoholic of course, after the heavy lectures involving quantum mechanics. The number of letters in each word yield up to 14 digits (not counting the integer part). Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

            How do you think they figured the numerical value of pi out to that many decimal places. I remember in school we did an experiment and got pi equal to 3.

                The number I posted isn't really that big in digits. Take a look here for the first 10,000 digits: http://www.joyofpi.com/pi.htm[^] Here's some references on calculating PI: http://eveander.com/pi/monte-carlo-circle[^] http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=360&lngWId=3[^] http://www.chinapage.com/math/s9/pi.html[^] Chris Richardson

                      3.14159 That's all I never needed. If the prof wanted more, he gave it to us. Plus, I always had my trusty HP 48-GX handy. :)

                                      But why? For me, it's the number of significant digits on the first pocket calculator I had. (I had to subtract 3.14 to see the remaining digits - clever me!!)

                                        20 (after the decimal) 3.14159265358979323846 I had to memorize it as a part of joining my fraternity :) When you were asked to recite it, you had to say it as fast as your mouth could possibly make the sounds.

                                          How many digits of pi do you have memorized?

                                          This is silly, but the digits I know come from a Simpsons episode, where Lisa visits a school for "gifted children". Two girls are playing paddy-cake but sing this: Cross my heart and hope to die These are the numbers that make up pi. 3 point 1415926535897 [fade out...] The bad part is that I can't recite or type the numbers unless I do it at the same speed as the girls were singing it. ;) --Mike-- Latest blog entry: *drool* (Alyson) [May 10] Ericahist | Homepage | RightClick-Encrypt | 1ClickPicGrabber "You have Erica on the brain" - Jon Sagara to me
