From San Francisco to New York, in museums, universities, classrooms and in the privacy of one’s own home, (and of course on Second Life), people are celebrating Pi. It’s the 21st anniversary of the celebration of Pi Day, an international holiday born at San Francisco’s Exploratorium. The number is Pi, 3.1415926535…ad infinitum. It’s today’s date and the starting time, the number you get when you divide the circumference of a circle by its diameter, and it cannot be expressed as a fraction. It continues forever.

    This is the worst Pi Day ever.

  2. Scott says:

    How on earth can it be international. The Americans are the only country on the planet that use the date format 3.14 everybody else goes from smallest to largest day, month , year, 14.03.09. And no arguments about, that’s how its said. I say a quarter past four, but I don’t write it 15:4.
    The date format, and Fahrenheit temperatures, Come on USA, join the rest of the planet in the 20th century at least. !

  3. Scott says:

    Oh, and its always confusing to work out what happened on the 9th of November !

  4. sargasso says:

    I for one, am happy to enjoy an American Pi.

  5. Mr. Fusion says:

    I’ll celebrate pi Day when I get around to it.

  6. zorkor says:

    I always sucked in maths. Calculus used to give me nightmares. Damn!

  7. Pie says:

    And pie to you as well

  8. Named says:

    Uh… it’s actually Steak and BJ day. But, for you sexless nerds, I guess you can have “Pi” day…

    Chicago Rare please!

    And, what’s Apple Pi without a fair-sized dollop of premium vanilla ice cream? Pi a la commode!

  12. Usagi says:

    Mmmmmmmm, pi…..

  13. Named says:

    10,

    You do mean a la mode, right? Commode is something COMPLETELY different.

  14. BubbaRay says:

    Now all you need is e^(i*pi) day, and we can start all over again. Who says you can’t have your pi and eat it too? WARNING — Don’t try this on Groundhog Day.

    BTW, nice pic, Hop!

    Nothing wrong with the Fahrenheit temperature scale. People live most of their lives between 0 and 100 degrees. When the temperature is outside of that range there are terms that cover the situation. They are “Damn Cold” and “Damn Hot”

    Celsiusians must live between -17.777777777777….. and 37.7777777777….. Now that is inconvenient. Also when Celsius set the scale up originally water boiled at 0 and froze at 100. Celsius was just a bit wacky.

    One thing that Fahrenheitics and Celsiusians can agree on is that -40 is -40 and damn cold.

    “(and of course on Second Life)”

    People still go to Second life?

    You ought to _see_ the lag when there’s a sale on!

  18. Named says:

    15,

    *sigh*. You do NOT live through 9 decimal places in Celsius.

    XKCD helped all you imperialists out…

    I do know that I can convert up the metric scale with nothing by a multiple of 10.
