    Pi is truly one of the most fascinating numbers in existence, and the quest for the ultimate end of Pi has been sought for time out of mind. This seems a fool’s errand, given that it seems to extend infinitely in mathematical loops beyond and nothing has ever been found to contest this, this is particularly remarkable when you consider the following: modern techniques have been used to calculate pi out to millions of digits, and at no point has the pattern ever been found to reliably repeat itself.

  4. I remember our maths teacher had a model filled with liquid that had a circle and some boxes in it as you turned it the liquid flowed out of the circle and filled 3 and 1/7 of the boxes if of course you extrapolate the 1/7 that gave you .142 didn't make any sense to me then at all
    But it does now
    Happy Pi day

    Very catchy .....
  11. Mmmmm pie....
  12. I shall celebrate at 2 and a bit seconds past nine minutes past 3 this afternoon.


    Actually, I probably won't bother.

  13. Pi is not just a number of infinite decimal places, it is the ratio between Circumference (C) of a circle and the Diameter(D) of the circle.

    C = Pi x D so if the diameter of a circle is known, multiply by Pi (3.142) to calculate the approximate Circumference and Circumference divided by Pi would calculate the Diameter.

    This is useful to calculate the diameter of a sphere (such as the Earth, ok its not a perfect sphere) so we know the circumference around the Earth is approximately 24,000 miles, so 24000/Pi would give an approximate diameter, about 8000 miles.

  14. Approximately. 3.14159.
  15. What is the circumference of Dianne Abbott?

  17. All of them, by the look of it.

  18. :eek:
    Perhaps this is a good moment to point out that it is a well established fact that people with learning difficulties often lash out at those they most wish to be close to ... :thinking:
  19. It is true that folk with learning difficulties have been attracted to Dianne in the past...

  20. Well said sir ... although talk of pi miles could cause embarrassment if one is at all prone to spoonerisms :rolleyes:
