ABSTRACT
Think all the way down to one billionth of a meter- a scale at which hydrogen and carbon atoms appear as large as base balls. Now imagine picking up those atoms and arranging them the way we want. At the molecular scale, the idea of holding and positioning molecules is new and almost shocking but it is something, in principle, that can be done. Imagine if we could, by any way, manipulate each and every individual atom of the products. For example, if we rearrange the atoms in coal, we get diamonds. If we rearrange the atoms in sand (and add a pinch of impurities) we get computer chips. That’s the basic idea of nanotechnology.
