oh, now with the refreshed context the problem makes some more sense
That battery for size comparison makes me think a box about the size of a
baseball might be ideal. I know sports memorabilia stores have clear
keeper boxes for baseball (and softball size?) However, now you're
introducing a new parameter to this puzzle: the ratio of volume of
nanogeezer to container. That wasn't a concern in the original unbounded
Imagine a crude surrogate for the nanogeezer: an ordinary cubic die. The
probability of a fair toss landing with any particular surface face up is
1/6. Once you put the die inside an acrylic cube of sufficiently small
proportion that the cube has no axis of freedom to turn, you've grossly
affected that probability. There is an ideal volume at which it is exactly
possible for the vertices of the die to touch the midplane of each face of
the container. There is a technical opportunity for that freedom to
manifest an actual change in orientation, but the constraint is such that
there is only the smallest likelihood that random shaking of the container
would ever orient the cubes in the magic moment.
So now we're talking about the ideal ratio of cubic (or otherwise?)
container to nanogeezer of any particular dimension... and material... and
I think i've lost scope of what it was we were looking for in the first
place. I'm having a good time free thinking on it, but I'm not sure where
the goal is anymore.
