Math and Disks

Math is only one of my passions. Ultimate Frisbee is the other. I’m playing this week at the USA Ultimate National Championships in Sarasota, FL.

Many mathy folks love Ultimate Frisbee, and I think that has to do with the beautiful physics of a disk in flight. One of my favorite quotes:

When a ball dreams, it dreams it’s a Frisbee. 
     – Stancil Johnson (Disc Golf Hall of Fame 2003)

I have several mathy jokes about various types of disks. For computer scientists…

How am I supposed to back up my hard disk if I can’t find the reverse switch?

For physicists…

There was a young fellow named Fisk,
A swordsman, exceedingly brisk.
So fast was his action,
The Lorentz contraction
Reduced his rapier to a disk.

And for mathematicians…

What is the volume of a disk with radius z and height a? pi · z · z · a
