Possible-impossible inspired.

In the wake of the next PI lecture on The Physics of Impossible Things, I did some research on this topic and found an interesting CBC link of Bob McDonald interview with Michio Kaku, the author of Physics of the Impossible: A Scientific Exploration into the World of Phasers, Force Fields, Teleportation, and Time Travel.

I found also interesting close to the end of the radio show (at minute 17:32) Bob's comments about Arthur C. Clark and his video self obituary.
