The tuning fork in the atomic force microscope, which measures the interaction between the tip and the atom.

About one-130-millionth of an ounce of force pushes a cobalt atom across a smooth, flat piece of platinum. Pushing the same atom along a copper surface is easier, just one-1,600-millionth of an ounce of force.
How about gold, which is more conductive than either metal? Gold should take even less force.

Color me jaded, but it seems the days of Boltzmann and Gibbs, when men solved these problems through sheer power of intellect are gone. Nowadays it's just smaller, thinner, lighter, purer, better machined, more highly polished, more collimated, better resolved, higher power, and more generously funded.

these are the same people who insist that man is descendent from apes, fish, and goo, correct?

Isn’t “one-1,600-millionth of an ounce” actually one-1.6 billionth of an ounce?
Can’t these scientists count?

Pushing an atom?... Science does not even know what an atom is...
Einstein worked with things too big to visualize or even calulate in the Universe and Niels Bohr (Quantum Physics) delt with things much too small to visualize or calulate..
What an atom "is", and What life "is", are blank spaces to science.. Pushing an atom is not pushing little balls revolving around each other.. Thats a mythical construct..
And the earth does "seem" flat from several perpectives..
Dead DNA appears exactly like live DNA...
So many mysterys.. so much that takes "faith".. for humans..

A single atom does not roll
Even a single atom will roll when Obama becomes POTUS. Obama will also end Brownian Motion by reaching to every particle and nudging it in the correct direction.

This is great info. I’ve always wanted to push a bunch of those little buggers around.

About one-130-millionth of an ounce of force pushes a cobalt atom across a smooth, flat piece of platinum. It would have been much less but they were using Union labor.
