Philosophical nit-pick: The logical positivists would not say this. They
would say that the question of the existence of atoms is meaningless *if*
they cannot be observed. Any statement that cannot be broken down into
directly observable entities is meaningless to the logical positivists.
Interesting bit of scientific history Kathryn.
