"But I am not afraid to consider the final question as to whether, ultimately---in the great future---we can arrange the atoms the way we want; the very atoms, all the way down! What would happen if we could arrange the atoms one by one the way we want them."
1. Can we move atoms?
Let nature do it for us: Chemical reactions
Let nature do it for us: Physical reactions - moving molecules across a cell membrane
Let us do it atom by atom
by human hand - STM |
2. To start with, how do we know where atoms are?
