Today our lab was honored by a visit from Dr. Ikalu Taw’tute, developer of the antigravity drive on Pandora. As you can see from the picture, his hands are rather large, though he did a very good job of holding one of our tiny Earth coffee cups.

It turns out that the Na’vi very much enjoy coffee. Their body chemistry is different from ours, and caffeine actually relaxes them.

Dr. Taw’tute was kind enough to write down for us, in our own mathematical symbols, the underlying principle behind his anti-grav drive. I noticed that they use τ rather than π in their mathematics, which is very civilized of them. Unfortunately, the last part of the equation is cut off in the photo, so you won’t be able to duplicate the drive.

Unless, of course, you manage to get your hands on some unobtanium.

And what is his learned on this: http://www.thepimanifesto.com/ ?

Yes, exactly!

If that means that on June 28 we get to eat 2 pies, it sounds good to me

I see that Vi had the same idea: http://www.youtube.com/watch?v=jG7vhMMXagQ. I’d use fresh fruit for the fillings, though.

Yes, in fact “The Pi Manifesto” also links to her video.

Yep, that’s how I found her video, in fact.

The phrase “the Tau of Pi” just popped into my head as I was thinking about this again. Of course, I had to Google it. Not surprisingly, it has been used already in this context, but fewer times than one might guess.
