Celebrating Pi Day 3.14

Updated on January 23, 2015

Celebrate Pi Day - March 14th

Mmmm. Pi Day! The nerdy holiday celebrated by math geeks worldwide. This is the day we gather around to celebrate that amazing little (long) number, pi.

Pi, approximately 3.14159, is the mysterious mathematical constant (number) that represents the ratio of any circle's circumference to its diameter.

Pi has its day, appropriately, on March 14 (3/14). Often a Pi Day celebration will have an extra special event set for pi minute (at 1:59pm). In the UK, Pi Approximation Day is often celebrated on July 22 (22/7) as 22 divided by 7 is an approximation for pi.

This day brings more fun to math classes around the world then anything else (second only to Math League). I wish you a very Happy Pi Day 2013!

About Pi Day

The mathematical constant pi is such an amazing number that it certainly deserves a day of it's own. Pi Day is observed on March 14 each year as the calendar date is 3/14 (in America at least). Special Pi Day celebrations and proclamations are made at exactly 1:59:26 PM which is Pi Second (which falls during Pi Minute!).

Pi Approximation Day is another pi holiday. Pi Approximation Day is usually celebrated on July 22. 22/7 is a rough approximation for pi (and in the European date format that is July 22).

Pi can also be celebrated on the 314th day of the year, which is usually November 10th, but November 9th in leap years.

Pi To The 50th Decimal Silk Tie - by Wild Ties

Pi To The 50th Decimal Green Microfiber Extra Long Tie
Pi To The 50th Decimal Green Microfiber Extra Long Tie

Not for the wanna-bes or the imitators, this necktie is for the true and the proud. This tie is for the nerds. Featured within this grand necktie is the great and almighty symbol of Pi. However, it is behind this symbol where the real intellect lays. It is here that pi is calculated in all its glory to the fiftieth decimal point. Your math teacher may know pi to the fifth decimal and you may even have a friend who knows it to the twelfth, but you are sure to impress them all when you have pi to the fiftieth decimal point. With pi it is all about respect and if you are sporting anything below 25 you may as well go home. And you don't want to go home, so sport your pride and receive the respect you deserve. Your time is now.

What to Eat at a Pi Day Party? - Pi Day Foods and Snacks

  • Pie!

    Any pie will do, but if you can put the symbol pi into the crust of say an apple or cherry pi it is even more festive.

  • Pizza!

    A pizza pie is a great add to a Pi Day party. To go all out, put pepperoni on in the shape of pi.

  • Cookies or cupcakes decorated with Pi are great ideas
  • Coffee, pie and donuts

    A mnemonic for C = pi*d is Coffee Pie Donuts

  • Anything else round - It would be best to have all of your refreshments be round to keep the theme going. Donuts, cheerios, M&Ms, ...

More Pi Day Activity Ideas - Things to Do for Pi Day

Here are a few Pi Day activities to make it a great day:

  • Make a paper chain out of 10 different colored papers. Choose one color to correspond with each digit, and see how long you can make it.
  • Pi Rhythm - Assign each of 10 students a digit. Have the digits of pi visible to everyone. Have students pat there legs in a steady rhythm. Have the students call out their digit when it comes up in the rhythm. Whenever a student messes up, they get "dinged". The person with the least "dings" after a set amount of time wins.
  • Compose pi nursery rhymes.
  • Hold a Pi Day Run - Plan a 3.14 mile run. Perhaps you could make it a fundraiser.

Pi Quotes

  • "Love is like pi - natural, irrational, and very important." -- Lisa Hoffman
  • "Programming graphics in X is like finding the square root of PI using Roman numerals" --Henry Spencer
  • "So here we have pi squared, which an engineer would call 10." --Frank King
  • "It helps us understand what pi is, not just food." --Robert Toth
  • "Pi is not merely the ubiquitous factor in high school geometry problems; it is stitched across the whole tapestry of mathematics, not just geometry's little corner of it. Pi occupies a key place in trigonometry too. It is intimately related to e, and to imaginary numbers. Pi even shows up in the mathematics of probability." --Robert Kanigel
  • "Exploring pi is like exploring the universe" -David Chudnovsky
  • "Pi is not just a collection of random digits. Pi is a journey; an experience; unless you try to see the natural poetry that exists in pi, you will find it very difficult to learn" --Antranig Basman

      Pi, definitely Pi...because it works for pumpkin, cherry and lemon meringue too. E does not.

    • smlybright 5 years ago

      So I think I have some studying to do because I know nothing about e.

    • alex89 lm 5 years ago

      I like pi, but mostly because I also like pie. I don't have a problem with e...

    • Michey LM 5 years ago

      They are different thinks... LOL, I like "Pi" as it is so useful in engineering, but I am not against "e"...

        OK, I picked e, but I really can't decide. I like them both.

        TonyB

      • anonymous 4 years ago

        e^x = its slope. What more can you say. You think that 100^x expands fast but it can't touch e. e is the best

      • jp1978 6 years ago

        Have I commented in this before? Today e is cooler, which rhymes with Euler. Also, e is more "natural".

      • anonymous 7 years ago

        the derivative of e^x is e^x. that is pretty much magical.

      • anonymous 7 years ago

        i like pie

      • Mary 8 years ago from Chicago area

        I had a college math prof who said that e "flows in the rivers." Sold! :) But my kids dig pi. Whenever they need to fill in a number on Mad Libs, they choose pi. Works great every time.

      • Kate Phizackerl1 8 years ago

        e - after all π is a derivation of e

      • unique freak77 8 years ago

        Pi rocks, but I'm sorry to say that e is way cooler. It's an actual LETTER! And it's more squiggly.

      • anonymous 8 years ago

        e, for sure. the natural log occurs everywhere in nature. it's not reserved to circles alone. Oh, but I have to say, the coolest thing I ever learned in college, was e^i*pi=-1. So, I guess they both pretty much rock.

      • religions7 8 years ago

        e is definitely cooler - for a mathematician (of sorts) like me... Though I'm ashamed to say that I didn't memorize more than three digits of pi - and haven't gotten beyond two for e. e's harder to explain, but that's part of what makes it cool... (and I love logarithms)

      Why pi is cooler than e: - Debate points for pi

      • the value of pi is bigger
      • pi is so special, it only shows under "special symbols" in word processor programs.
      • People confuse Euler's Number (e) with Euler's Constant (gamma). There is no confusion with the one and only pi
      • e is named after a person, but pi stands for itself
      • pi cannot be confused with a hallucinogenic drug
      • pi is tasty
      • Pi Day rocks! No one cares about e Day.

      Why e is cooler than pi: - Debate points for e

      • e is easier to spell than pi
      • e is on a keyboard, but pi is not
      • ln(pi) is an ugly, but ln(e) is 1.
      • e is used in calculus while pi is used in baby geometry
      • 'e' is the most commonly picked vowel in Wheel of Fortune.
      • You don't need to know Greek to be able to use e
      • You can't confuse e with a dessert

      Pi Jokes

      Mathematician: Pi r squared

      Baker: No! Pie are round, cake cornbread are square!

      -----

      A mathematician, a physicist, and an engineer are all given identical rubber balls and told to find the volume. They are given anything they want to measure it, and have all the time they need. The mathematician pulls out a measuring tape and records the circumference. He then divides by two times pi to get the radius, cubes that, multiplies by pi again, and then multiplies by four-thirds and thereby calculates the volume. The physicist gets a bucket of water, places 1.00000 gallons of water in the bucket, drops in the ball, and measures the displacement to six significant figures. And the engineer? He writes down the serial number of the ball, and looks it up.

      ---

      In Alaska, where it gets very cold, pi is only 3.00. As you know, everything shrinks in the cold. They call it Eskimo pi.

      ---

      What do you get if you divide the circumference of a jack-o-lantern by its diameter?

      Pumpkin pi.

      ---

      What do you get when you take the moon and divide its circumference by its diameter? Pi in the sky.

      What do you get if you divide the circumference of a bowl of ice cream by its diameter?

      Pi a'la mode.

      Celebrate Pi Day By Doing What You Love - But Pi Oriented

      What's great about Pi Day, is that you can celebrate it doing whatever it is that you love doing. Everyone can make an amazing Pi Day project!

      • If you love music, play Pi on a piano or instrument of your choice.
      • If you love photography, take your camera to the streets and photograph numbers on buildings and signs in your town and then line them up to Pi. Take single digits, and also try to get some photos of strings of numbers. Then create a display of your photos. Check out this great example: Pi Day to the 36th digit.
      • If you love sports, find photos of athletes wearing their numbered jersey's and line them up to represent Pi. Babe Ruth wore #3. That's a great place to start. Then choose an athlete that wore 1 or 14 and continue for the first however many digits of pi you wish to display.
      • If you like making movies, create a stop action animation using anything...sand, legos, pencils, soda cans, people, anything.
      • If you like acting, write a Pi Day skit and perform it.
      • If you like writing, write a Pi poem, or create a false newspaper that includes fake Pi related stories (complete with ads, classifieds, and obituaries).
      • If you like cooking, bake a Pi Pie. Another food idea is to use a serving dish shaped like a cylinder, half sphere, or even a cone, and prepare something in it, and display the calculations for the volume of that item. For instance, if you make a trifle in a trifle bowl (which is nearly a cylinder), you can calculate volume with this equation.

      Pi (1998) - Starring: Sean Gullette, Mark Margolis

      Pi (artisan)
      Pi (artisan)

      Max Cohen, played by Sean Gullette, is a mathematician searching for the patterns that exist in the world - in nature, science, society, business - everywhere. However in this low-budget black and white psychological drama, Max is not the only one searching for patterns. Everyone seems to be searching for patterns in order to progress their cause - whether financial, religious, or political. And now, Max has dropped deeply into paranoia.

      This is a complex movie, that requires your full attention.

      It's not for the light happy Pi Day celebration, but a great watch at night after all the Pi Day celebrations are over.

      Pi won the Director's Award at the 1998 Sundance Film Festival.

      The Punny Pi Guy

      At your Pi Day event, interview a guy with pi symbols stuck all over him. Have all of his answers be pi related - heavy on the puns. It's best when the interviewer gets annoyed at the puns and tries to come up with harder questions (to which Punny Pi Guys always has an answer for).

      For example:

      Q. What's your favorite food?

      A. Pie.

      Q. Other than pie.

      A. Pizza pie.

      Q. Other than pizza pie.

      A. Paella?

      Q. What's you favorite story?

      A. Peter Piper

      Q. What do you want to be when you grow up?

      A. A Pilot.

      Q. Your favorite movie?

      A. Pirates of the Caribbean

      Pi 3.14 in the Bible
      Pi 3.14 in the Bible

      Pi In The Bible

      Is Pi in the Bible? Well, yes, sort of.

      In the description of Solomon's Palace, specifically in the verse I Kings 7:23, the Bible gives the dimensions of a round "molten sea", which is an immense round basin of cast metal. Since it gives enough dimensions, we can work backwards to calculate pi. The Bible says the following:

      And he made a molten sea, ten cubits from the one brim to the other: it was round all about, and his height was five cubits: and a line of thirty cubits did compass it about. (KJV)


      The problem that arises is that if you do the math on those figures then pi equals 3, but we know this is not accurate. I believe that since the Bible is not a science book, or a math book, that this error is simply stems from the writer rounding to the nearest cubit.

      Visit this site for more information on Pi In The Bible.

          Why is "pi" Buzz Lightyear's favorite food?

          Because it goes "To Infinity and beyond"!

          Why wouldn't the circle go out with the quadrilateral?

          She was afraid he would be a square!

          even if you earnestly try.

          Simple enough for a child to use,

          Yet could pick Einsteinâs brain.

          Moves about with ease, does he,

          Sporting his endless digit-train.

          Didn't know there was a Pi day. I'm going to celebrate this year by rewatching the first episode of the new cable TV show "Touch." (The next episode isn't until March 19th). Also I'm going to learn 8 digits of Pi, be appreciative of the nautilus shell on my bathroom counter, and maybe make some new fractal art. And perhaps I'll have pie for breakfast.

          Pi is an interesting number. Take each digit in turn and it seemingly gives you a sequence of random digits between 0 and 9. The sequence does indeed pass all the tests for a random number generator. Nobody has yet proved that the sequence is recurring or that any digit between 0 and 9 is more likely to occur than any other..

          I love "e". But since there is no e-day, your lens is the nearest to celebrate something mathematical. Great lens. 5*'s.

          PS: I came across this equation quite some time ago, but I still haven't been able to digest it. How can two irrational number, an imaginary number and the number 1 cancel each other perfectly?

          1 e**(i*pi) = 0

          PPS: In case you enjoy mathematics, you might want to check out Are you afraid of mathematics?

          Following on, I wonder if any mathematician types out there have experimented with working out pi in bases other than 10? Surely there must be a base that would give pi as a whole number?

          Sir, I send a rhyme excelling

          In sacred truth and rigid spelling

          Numerical sprites elucidate

          For me the lexicon's full weight

          Count the letters in the words for pi to 20 decimal places easily remembered.
