[math-fun] Aerobie aerodynamics

Many years ago, Alan Adler produced an excellent 38 min. video on the invention of the Aerobie flying ring. He sent the master it to an L.A. cassette duplication outfit who then threw it in a dumpster and flew-by-night. I just uploaded a low quality recording at gosper.org/aerobieaero.mp4 . If you find it boring, you're paying insufficient attention. --Bill
