What Is an Atom?

Extract

For a number of years I have been demonstrating at my seminars that the atom is no longer atomic, that mechanics is no longer mechanistic, and that similar paradoxes of advancing science can be formulated throughout its extent. The point has been reached, however, that a call for a revision of terms or some such reform should be issued. At one time, indeed, I gave a list of terms to be dropped altogether. They refused to be dropped. I ask now: Will they permit themselves to be modified or to be reallocated?
