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.
