The Circle Constant War

So I was romping around the internet as usual, and I found this:

I won’t talk much about the article itself so you guys can check it out, but dang, I’ll just say that it was somewhat enlightening.

We all know that pi is a constant you magically get by dividing an arbitrary circle’s circumference by its diameter, but isn’t it odd that we don’t really use the diameter that much? Instead, it’s radius this and radius that. The unit of turning is even called the radian.

Then why don’t we use 2π as the constant, because the radius is so much more important? Thus, 2π was given a name, Tau.
