Take your copy of K. Eric Drexler’s book Nanosystems down off the shelf and turn to page 4.  There you

If you don’t have the book handy, here it is:







































Call that phase 1, the imagining of a nano-bearing in 1992.

Go forward from 1992 to 2006 and the imagined nano-bearing has been simulated using NanoEngineer-
1, a simulation program.
To see the simulation in Apple’s Quicktime, go to:
willware.net/bearing-animation-20061206.mp4

Call that phase 2, the simulation of a nano-bearing in 2006.

When will
phase 3, the actual creation of such a bearing take place?
When will
phase 4, the actual construction of a nano-scale watch with face hands take place?

Phase 5 is when we create a nano-android who needs the nano-watch on his nano-wrist.
