Happy Square Root Day!

I hope everyone has a very happy square root day. This geekiest of mathematical holidays only happens 9 times every century, so make the most of it and… I don’t know… do some recreational mathematics or something. Whatever makes you happy.

Be there, and be square!

    Lol, indeed… of course, sometimes i feel like my maths studies are like trying to walk in wet mud; you get one foot free only to find the other is in up to mid-calf (direct translation: my joy at completing exponents for now was short-lived, roots kicked me off my high minutes later :p)

    Oh, but it doesn’t stop the crud treats from sounding scrumptious!

    How fitting! :D

    square brownies with caramel ‘roots’
    Mmmm… I may have to try making some of those!
    And your welcome. My square root day is going just fine, thank you! :)

    Gah, I was thinking about the wrong day there. But I did have a saavy math instructor who’d bake us crud treats on various math-related ‘holidays.’ Hehe, my bad…

    I hope you’re planning on cutting them into squares. :P

    I think it probably helps to be a bit crazy if you’re a mathematician. Funny thing is, I remember playing with happy numbers when I was a kid, but I never knew what they were called back then…
    And thanks. :)

    Yeah, I only discovered it today. :D

    Anytime. :)

    Haha, i found out about this for the first time today! I celebrated by finally getting my head around exponents :p

    I remember my math instructor in middle school would have square brownies with caramel ‘roots’ for us on square root day. Ah, fun times…
    Well, thank you for bringing this up. Hope you’re having a good square root day too!

  14. Wow, square-root day?
    Nifty-keen. Thanks for sharing!

    Thank you, I’m going to go get some radishes.

    Nice; I was planning to make a post on this myself. Never knew about happy numbers, crazy mathematicians with too much time on their hands.
    Excellent closing line.

  17. I knew Pi Day was coming up, but I didn’t know about this one. Amusing.
