The biologist depends on puzzle: to the maturation of the science of physics much as the crossword solver depends on a large and correct vocabulary. The solver of crossword puzzles needs not just a good vocabulary but a special vocabulary. Words like inee and oke are vitally useful to him but are not part of the vocabulary of an English professor.
