Tau day is coming!

After watching some “Pi is Wrong” videos by Vi Hart (on Khan Academy) my son showed me the Tau Manifesto.  He started laughing when I said, “Wait, wait, that means…” and then scrolled up to show exactly what I was astounded to realize.  Then, at the perfect moment for clinching a sale, he clicked on the link to buy the Tau Day t-shirt.  In my excitement, I bought one for each of us: https://teespring.com/tauday#pid=369&cid=6521&sid=back.  We’ll be ready for June 28th!
