About this book

The A B C of Relativity by Bertrand Russell lists subjects including the velocity of light, clocks and foot rules, and the special theory of relativity. The discussion of co-ordinates explains that initially haphazard assignments help avoid physical assumptions that could slip into apparently meaningful measurements. The text assumes a calculable interval between events that are close together, while explicitly withholding that assumption for events farther apart.

An illustration compares orchestral music with its printed score to explain a resemblance in structure between things of different intrinsic qualities. The comparison says that knowledge of the rules allows the music to be inferred from the score or the score from the music.
