Pi Day!

March 14th (3/14) is, of course, Pi Day (3.14… get it?). so this made me wonder what other days are out there. Let’s take a looksie:

January 2nd – Apery’s Constant Day
January 3rd – Plastic Constant Day
January 4th – Porter’s Constant Day
January 5th – Lieb’s Square Ice Constant Day
January 6th – Golden Ratio Day
January 9th – Brun’s Constant For Twin Prime Day
January 13th – Viswanath’s Constant Day
January 18th – Khinchin-Levy Constant Day
February 5th – Feigenbaum’s Alpha Constant Day
February 7th – e Day (Napier’s Constant)
February 8th – Fransen-Robineson Constant Day
April 6th – Feigenbaum’s Delta Constant Day
May 5th – Nuclear Magnaton times 10^27 Day
May 6th – Stefan-Boltzmann Constant times 10^8 Day
June 2nd – Avogadro’s Number divided by 10^23rd Day
June 6th – Planck’s Constant times 10^34 Day
August 8th – Electric Permittivity of Free Space times 10^12 Constant Day
August 9th – Coulomb’s Constant divided by 10^9th Day
December 10th(^3) – Molar Mass of Carbon 12 Day

Some might disapprove of my decision to include either one or two digits for the ten’s and hundreth’s place holders. Example: 4.3 or 4.03 could both be taken as April 3rd.

My personal favorite might be Nuclear Magnaton times 10^27 Day.

    Just to let you know. Avogadro day is actually October 23 for the 10^23’rd part. Believe me I know. Not only do I pride myself for my vast accumulation of dorky knowledge, but my high school played the Mole Song every mole day over the loud speaker during morning announcements. “A mole is a unit, or have you heard, it equals…” I now have no choice but to sing the first bit of that song to remember what Avogadro’s number actually is when I’m doing my chem calculations by hand.

    Avogadro Day is based off the multiplier?!?!

    That is Total crap.

    This post is Ameri-centric.
    Since we write dates the right way round in the UK, Pi Day isn’t until the 3rd of Octemvobary.

    Very true, Avagadro Day (or “mole day” at my high school) is 10-23. Sorry.

    Nuclear Magnaton times times 10^27 Day is awesome, if for no other reason than it is also Cinco de Mayo.

    “Somebody get this kid a girlfriend.”

    That made my day right there.

    Wait, so now we’re going to employ guns, cars, and math to get the ladies. Mike, one of these doesn’t fit with the others…

    They have to celebrate mole day on its multiplier, other wise it would be in the middle of summer break and who wants to celebrate mole day on summer break?
