It’s officially Pi Day. That crazy number you had to learn about in school. Geometry. Where Pi equals the circumference of a circle and is a constant.

The calculation of Pi as 3.14 was first introduced by Greek mathematician Archimedes, which is why today, March 14th is Pi Day. It became officially recognized by Congress in 2009 and is **celebrated with fun and pun filled antics.**

We, at RESTECH IT Services, have ordered Pizza **Pi**e and Apple **Pi**e for a staff lunch today. Which would make sense since we have a group of computer engineers (math inclined) to feed.

**Pun Filled Pi**

Other pun filled celebrations include MIT (Massachusetts Institute of Technology) who releases its undergraduate admission decisions on Pi Day. Congrats to those who are accepted!

Pi is used frequently in NASA’S Jet Propulsion Lab to calculate space travel. NASA is inviting gifted math minds to compete in its “Pi in the Sky” challenge to solve some planetary math problems this year.

I wonder if “Big Bang Theory” will be running a Pi themed show as a rerun somewhere tonight.

**Pi is Infinite**

PI actually has an infinite number of digits that go on and on and on and never repeat. Which makes it entirely unique.

As computer technology has become more powerful, it appears a new mathematics challenge has arisen to see who can calculate even more Pi digits.

The current Pi Digits Record goes to Peter Trueb. He was able to calculate Pi to 22.4 trillion digits. That’s way beyond my real comprehension but interesting anyway. Peter’s accomplishment broke the record that was set in 2013 which was 9 million digits.

As technologies advance and computing power continues to grow, these records should be broken more frequently.

**So how many Pi digits does it take to calculate the known universe? **

Mathematician James Grime seems to think that you can calculate the entire circumference of what we know as the universe with just 39 digits of Pi.

It makes me wonder what we can calculate with 22.4 trillion digits of Pi.

Instead I will eat my pizza **Pi**e today and assume that 3.14 is all I need to get to its circumference.

Here’s to all the engineers, mathematicians and other science inclined minds who actually use this stuff,,, **And for the rest of us, let us eat Pie.**
