Manipulation of the Very Small

A well-worn cliché is that cells are machines, the components of which are molecules. This leads to an important point: in general, molecules are too small to be seen or manipulated directly. How can one study a machine if you can’t look at or manipulate its components? To use a computer science analogy to this problem, imagine trying to reverse engineer a PC from a hundred yards away, with your only tools for manipulation being a collection of bulldozers and excavators and such that you direct by remote control. What sort of things could you do, and what sort of things would you learn?
