Happy Square Root Day!

Celebrate it now!

The next Square Root Day is 4/4/16

How will you observe this momentous occasion?

I may make a square pan of some sort of root vegetable concoction for supper.

    I think I’ll watch the movie ? (pi)

  2. dcs says:

    Wouldn’t 2/4/16 be an even better square root day?

  3. Laura Lowder says:

    hmmm …. post to my blog, send a few emails…
    And maybe plant some sort of root vegetable in my garden when I get home in honor of the occasion? Unfortunately, all the vegetables I know have round, not square, roots…

  4. Andrew, UK and sometimes Canada says:

    Perhaps this explains the square-looking Eucharistic wafer displayed on Fr Finigan’s blog from the REConference out west.

  5. Barrett says:

    Are we going to celebrate Pi day as well 3.14?

  6. Tzard says:

    What about Sweet Potato pie? I’ve seen it made with a little bit of ginger in it (also a root vegetable). You might even mix in some mashed carrots – another root.

    What will the Church be like in 12/12/2144..?

  8. Gloria says:

    Tzard – Make sweet potato pie just like pumpkin pie with the same spices. It tastes exactly like pumpkin pie. My Missouri Gramma used to make it.

  9. Happy square root day, since I’m a math nerd I love these kinds of days.

    Hold on, there is someone named kettle on the phone for me.

  11. Art says:

    Great idea! I have a vegetarian taro root cake I made in a square container. I’ll have to slice up and fry some pieces for dinner and see how it turned out.

  12. Corleone says:

    WHA???! I’m just finding out about this now??? This only gives me ? ?360 ‘ 2 = ? 4 ? {± 40 people } where apetite = ? !

    I will NOT have this be a repeat of the “Palendrome Day” party of 2002.

    sooo… if I turned 50 on square root day…. how old am ? :)
    please don’t base your answer on my typos

  14. Richard says:

    Not to be a pedantic curmudgeon, but aren’t 3/3/09 and 4/4/16 just multiplication days – like 3/6/09 will be an addition day? 2/4/16 will be an exponential day.

  15. Jenny says:

    This is why I love this blog…all kinds of weird fun mixed with a whole lot of correctness (except political – thank goodness). Thanks for enlightening us in so many ways, Father.

  16. Tzard says:

    Thanks, Gloria. I’ll try it tonight.

  17. Amy P. says:

    I greatly detest math, and it took me a while to figure out “Square Root Day”…

  18. Carrot cake! That’ll work… right?

  19. Richard: pedantic curmudgeon

    Better perhaps than being a psilological doryphore.

  20. leutgeb says:

    I had that thought when I wrote date on a white board this morning!
    No plans to celebrate tonight.
    Enjoy your root vegetables, Father.

  21. Joan Moore says:

    03/03/09 – hadn’t thought of it! I’m looking forward to 09/09/09 – that will be my fortieth wedding anniversary!

  22. Alice says:

    Hehe. I’ll have to remember to wish my fellow teachers a happy square root day at our staff meeting this afternoon.

  23. PMcGrath says:

    I’d rather have a Riemann Hypothesis day …

    All non-trivial zeros of the zeta function have real part one-half …

  24. Immaculatae says:

    Yes,carrot cake! MMmmm!

  25. truthfinder says:

    It’s rather like Mole Day: Oct. 23 from 6:02 am to 6:02 pm.

  26. themickb says:

    I didn’t realize it was Natural Square root day!

    I am more of a Pi Day man myself, only eleven more days!

    3.1415926535897932384626… (if memory serves me correctly).

  27. Brian Day says:


    Have there been 10^23 Mole Days? :P

    “… a square pan of some sort of root vegetable …”


  29. truthfinder says:

    my university lab instructors have made a point to us to celebrate the day, not of course with as much emphasis as Darwin Day, but you can’t win at everything. So a couple of us did celebrate Mole Day.

  30. Edward Martin says:

    I celebrated square root day celebrating my wife’s 40th birthday. She was born on an interesting mathematical day, sort of square “rootish” 3/3/69.

  31. PS says:

    What happened to the girl who flirted with the Maths professor?

    She got a square root and multiplied.

  32. Old Bob says:

    In engineering circles, pi are square. At Baker’s Square, pie are round.
