Maybe Google or somebody could commission a children's museum exhibit in the form of Ganson's futernity machine extended to a length of fifty 100:1 gearboxes. The boxes would be labeled with the powers of 10 and Conway names, and signs would label the first few shafts with, e.g., "x turns per second," "x turns per minute," ..., "... years," "... millennia," galactic rotations,..., solar nova consumes Earth, universe runs out of gas (with a gratuitous universal joint as an inside joke), ..., googol. --rwg
Someone should create an applet that does this: "Give or take an unknown but fixed error, it is now 0000000000000000000000000000000000536112314159265359 seconds since the big bang." Clicking on each zero-digit would bring up a little text window telling you what the universe will look like when that particular 0 changes to a 1. Jim Propp
