4 Nerdy Ways to Celebrate Pi Day

If you’re a math geek who lives in the United States, you may have noticed something interesting about the date. It’s March 14! That’s right 3/14, an approximation of pi!

Pi is arguably the most famous mathematical constant. Simply put, pi is the ratio of a circle’s circumference to it’s diameter. Who cares! Well you all should care because it’s important in geometry and trigonometry; anywhere you have a circle, you have a pi. (Well, two pi. Tau, actually. We’ll get back to that.) Plus, it never ends. The decimals go on forever! We’ve got it calculated out to about a million digits, but there are more. So many more!

So pi is pretty cool. But it’s not without its detractors. There are those who argue that math would be much simpler and more elegant if we could extricate ourselves from the tyranny of pi. Vy Hart makes a compelling argument for abandoning pi in about five minutes:

But, let’s face it, pi has a special place is our social psyche, which is why we celebrate it every year. What can we do to celebrate? Answer: Lots of things!

Eat pies!


Run 3.14 miles.

I mean, you did just eat two whole pies.

Get your nerd on and recite a bunch of pi digits.

Challenge your friends! Whoever recites the most digits buys the next pie!

Write a Pi-ku.

This might be my favorite way to celebrate Pi Day I’ve ever heard. Instead of using the 5-7-5 pattern, use 3-1-4. For example:

Circles have
pis. What’s with that?

Today isn’t Pi Day everywhere. It only works in places where the date is written month first. If you are one of the unlucky ones, you just have to wait until July 22 – or 22/7 – which is known as Pi Approximation Day. You may have to wait, but you can take solace in the fact that 22/7 is a better approximation of pi than 3.14. Either way, it’s a great day to geek out on math.

Share your own Pi-ku in the comments!

Tau is NOT any better!
If you want to make the formula for the Circumference of a circle [2 times Pi times Radius] [2πr] more simple, instead of replacing Pi (π) with Tau (τ), you can just replace Radius (r) with Diameter (d) so the Circumference formula would simply be Pi times Diameter [πd].
Now, let's take the Area of a circle [Pi times (Radius squared)] [πrr]. If you were to replace that with Tau it would be [(Tau divided by 2) times (Radius squared)] [τ/2 X rr]. Does this seem more simple?

Our son-in-law is a ridiculously smart math genius who works for Google at it's world headquarters in California and can't even divulge to us everything that he does there. Every day is like Pi Day to this guy.

This is fun! Never connected March (3)
and the 14th with "Pi" - Life of Pi - y mas.
Ha ha ha!
