"'The Sun' is a book of facts and achievements, and not a discussion of theories, and it will be read and appreciated by all scientific students, and not by them alone.

"Sir Robert Ball has the happy gift of making abstruse problems intelligible to the 'wayfaring man' by the aid of simple language and a few diagrams.
