This morning I asked my phone if there were any computers currently calculating pi. It pulled up a couple of different articles from August of 2010 about two men who built a computer for that express purpose. It took three months for their machine to find the five trillionth digit.
I think pi is a metaphor for the universe. We think we can see pretty clearly what it is, but when we take the time to look a little harder and learn a little more, the possibilities for discovery are vast, and vastly expanding.
Happy Pi Day!
