Sharp eyes! Certain classification codes were reserved in early drafts of
the DCS for possible future insertion of new topics. These gaps are
artifacts of that editing process.

This is a great suggestion for Jerry Zani, the chair of our DCS Committee to

In the matter of physics the first lessons should contain nothing but
what is experimental and interesting to see. A pretty experiment is in
itself often more valuable than twenty formulae extracted from our
minds.
