Happy WHAT, you may ask? Well, those who read this blog may recall me writing about pi day on 3/14. There were many geeks writing about pi on that day. And many of them linked to Vi Hart’s video telling us what is wrong with pi and how we really should use tau (twice pi or 6.28) instead. It seemed strange to me that they would want to celebrate pi by dissing it. But it’s okay today, as Vi will explain in the videos below. By the way, if you have never seen one of Vi’s videos, they are very creative, but can be a little exhausting. Be sure to check out her website and her series on Fibonacci numbers. If you still thirst to know more of tau after watching Vi’s explanation of this interesting number, you can check out the tauday website.
As for me, I see Vi’s point but still have no problem with pi. As a matter of fact, I think it’s time to go have a piece of pie. Happy tau day!
