1. It’s irrational to ask π to enter its name numerically, although it would be a transcendental experience.

    I note that there are two forces against π day being celebrated on March 14.

    1) It seems some are promoting 6/28 instead for tau (τ) day. I don’t know what you are supposed to eat on tau day.

    2) Given a European audience, where the format is generally day-month rather than month-day,
    i. there is no 31/4 (April 31)
    ii. there is no 3/14
    iii. there is no 62/8 (August 62)
    iv. there is no 6/28

    Both the US and Europe agree Nov 9 is the 314th day of 2020, and would be the truer international pi day. τ day would not work that way.

    And sadly, in my youth, I had π memorized to > 100 places. Now I can barely remember why I’ve walked into a room.

  2. @ Catlover – I made a similar mistake when writing code in high school for a double-precision programming assignment. Four decades later I can still rattle off more digits than anyone could ever possibly need for any practical calculation.
    P.S. I wonder whether there was an increased response to “Pi Day” five years ago, when US format and a two-digit year would have resulted in 3/14/15. One could even add the time “9:26:53” to that, as long as nobody bothers to point out nitpicking rounding problems (present company excepted, of course).

  3. @Kilby – yes, there was. In the proper geek circles, of course. And yes, some people went down to the second for the celebration (which generally included pie…).

  4. Even though the improvement in precision is minimal, I like TedD’s suggestion (22/7) much better then my idea of appending the time.

  5. Kilby: I have a friend who was married on 3/14/15.

    I don’t think it was planned that way, so it was a pleasant coincidence.
