*Math is everywhere and it is everything. Numbers make up everything. I LOVE math and I LOVE pi.*

## 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 2019!

## 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.

## Decorate for Pi Day

## 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. Get this...you can even buy a pie pan shaped like pi !!! Having people over for dinner? Chicken Pot PI !

**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.

**Coffee, pie and donuts**A mnemonic for C = pi*d is Coffee Pie Donuts

- Cookies or cupcakes decorated with Pi are great ideas.
- 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 ArtHave a decorating contest, where everyone decorates a Pi symbol. Let them know that you want more than just simply coloring it, you want it completely decorated, after all, it's Pi Day, and Pi deserves it.

## 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

## Celebrate Pi in English Class

### Pi Day Beyond Math Class

Can't figure out how to celebrate Pi in your English class? How about writing a story where the number of letters in each consecutive word make up pi? You know...first word 3 letters long, second word 1 letter, third word four letters, ...

For example:

3.1415926535...

Him, I love. I exist, amazingly. So absent bliss. All alone. ...

Another great idea is to write your own Pi-ku math poem. Who wouldn't love a Pi Haiku?

## Hold a Debate: Which is cooler? - The Pi or e Debate

The age old debate. Which is cooler pi or e?

At your Pi Day Party, hold a mathematical debate. Assign a person to speak for pi and another to speak for e.

(It's Pi Day, not e-Day, so of course, no matter how the debate goes, Pi will win. TODAY Pi is cooler, hands down.)

### 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.

## 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

## Al G. Bra's Pi Day Video Collection

This guy truly loves Pi Day, and it shows! If only the whole world had his enthusiasm for math...

## 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.

## Pi Drinks

### Frozen H2O Shaped Like Your Favorite Irrational Number

When hosting the Pi Day soiree at your geek bachelor pad you'll need the proper equipment to ensure success. Square ice cubes just will not do. Round out your party with ice shaped like pi amazon.

Also check out the ultimate in Pi Day cocktails...the Pi-Tini.

Here you can wish everyone a Happy Pi Day, share your Pi Day stories and ideas, and ask any Pi questions.

**Ram Ramakrishnan** on March 14, 2012:

Inherently a very nice guy,

he must be, this enigmatic Pi;

Never get to know him fully,

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.
