Pi Day and How to Celebrate

Did you know that March 14 is Pi Day? The reason it’s called Pi Day is because Pi (or π), one of the most well-known mathematical constants, is the ratio of a circle’s circumference to its diameter.  For any circle, the distance around the edge is a little more than three times the distance across.

According to Pi Day’s website, typing π into a calculator and pressing ENTER will yield the result 3.141592654, not because this value is exact, but because a calculator’s display is often limited to 10 digits.  Pi is actually an irrational number (a decimal with no end and no repeating pattern) that is most often approximated with the decimal 3.14 or the fraction 227.

Now there are several ways one can celebrate Pi day. If you happen to be like me and have math as your weakest subject, you can always just eat a pie whether it’s a fruit pie or a pizza pie! Here are some good Pi(e)s to try for Pi day!

A Cornish Pasty-This traditional pie hails from Cornwall, England. These pies are different because they are basically portable. They are made with a shortcrust pastry and filled with minced (ground) beef, rutabaga, onion, and potato. They are generally eaten hot or cold.

Pork Pie-These are also made using a hot water pastry crust, pork pies are made from minced pork and filled with a layer of jellied pork stock. These are usually eaten cold.

Steak and Kidney Pie-Another popular meat pie which uses steak and kidneys of either lamb or goat. Instead of shortcrust pastry puff pastry is used.

Apple Pie-One of the most popular non-meat filled pies in the UK and the most popular pie in the US. Tart apples add some heavy flavor and sweetness with a delicious shortcrust pastry to balance everything out.

Trivia: The symbol for Pi has been in use for over 250 years. The symbol was introduced by William Jones, a Welsh mathematician, in 1706. The symbol was made popular by the mathematician Leonhard Euler.
