Polymaths

I wonder if there are any group members who can calendar calculate, crunch huge numbers with ease, etc? (maybe polymath isn't an accurate term for such ability. If so, please excuse it.)

In correcting my usage of the term Polymath, I found this article interesting:

Polymath is a far more general term, of course. Look and judge for yourself, don't mind what we say entirely.

At any rate, my initial question was inspired by the subject of synesthesia and Daniel Tammet, who is capable of astounding mathemtical feats.

Sure, it's a valid question. Math progidies have been around almost forever.

I can using Mathematica :p
