An example of an analogy used to exlpain a scientific idea:

"…it is due to the fact that an unelectrified [neutral] atom is so elusive that unless more than a million million are present we have no means sufficiently sensitive to detect them, or, to put it in another way, unless we had a better test for a man than we have for an unelectrified molecule, we should be unable to find out that the earth was inhabited."
