In the month/day format of today's date 22/7 - the fraction is a close approximation of π. (For those of you that didn't know. ) :D

    Heres a funny concept. Take a piece of paper and draw a perfect a circle as you can on it. Now draw a line through the center to each edge and give it the diameter of 1.
    Note how its impossible to state the circumference of that circle due to the transcendental nature of PI.
    But by all logic and using your eyes, you SEE that the circumference of that same circle must be resolvable, because you can SEE it has a beginning and an end. It has a beginning... but no end?

    Another neat concept:

    For an even closer approximation of pi you can use 355/113 which only misses by .002%. Thanks to old Marvin Klotz.

    10) e is less challenging to spell than pi.


    9) e ~=2.718281828459045, which can be easily
    memorized to its billionth place, whereas
    pi needs "skills" to be memorized.


    8) The character for "e" is so cheap that it can be
    found on a keyboard, but pi is
    special (it's under "special symbols" in word
    processor programs).




    7) Pi is the bigger piece of pie.


    6) e has an easy limit definition and infinite series;
    the limit definition of pi and the infinite
    series are much harder.


    5) With e you understand what it is even though
    you start learning it late when you are in
    pre-calculus, but pi, even after five or six years
    it's still hard to know what it really is.


    4) People mistakenly confuse Euler's Number (e)
    with Euler's Constant (gamma). There is no
    confusion with the one and only pi.


    3) e is named after a person, but pi stands for itself.


    2) Pi is much shorter and easier to say than "Euler's Number."



    And the number one reason why e is inferior to pi is...


    1) To read pi, you don't have to know that Euler's name is really pronounced Oiler.

    Well, at least 22/7 is closer than what the Indiana state legislature tried in 1897 to define the value by law: 3.2. The Hoosier State, known for its sugar creme variety (why can't I get that in WA?), should've stuck to the pi(e) it does best.

    But that's harder to remember! :D

    Hilarious!

    Awesome dude! Glad to be of service! LOL

    @Phil - hope you got some sugar creme type to celebrate!!
