I saw a t-shirt today with the symbol pi (π) and it was followed by the decimal equivalent taken out to 50 decimals. You might remember from grade school or high school that pi is a irrational number that appears to have no repeating patterns. You normally use this factor when you are doing calculations with circles and such.

I immediately wondered about the popularity of pi based on the web domain registrations. What I found was more inconsistency than I expected. Instant Domain Search is a pretty cool tool to look this up quickly. Here is what I found:

and from here to 31415926535897932384626433832795028841971 is available.

I would have figured that people would have consistency bought each additional decimal place, but it seems some versions are more interested to people than others.

I recently purchased this t-shirt from threadless:

I love it. But now I can think of so many more I’d like to add. First, I’d like to place a hole in the middle (Pie-hole, as in, shut your).

Welcome back from vacation! I’m leaving on mine tomorrow. I’ll be in touch!

Seems to me that if you wanted to really do this right, you’d drop the first digit (the 3), register the remainder, then make the 3 a sub-domain. In other words:

1. Register 14159

2. Set up 3 as a sub-domain

3. Point people to the web address 3.14159

But that’s just the geek engineer in me thinking.

You’re right, by the way, in that the Instant Domain Search tool is very cool.
