The symbols we now use for numbers evolved very slowly over the centuries. The concept of using a zero took even longer. Most of the mathematical symbols we take for granted today, like an equals sign or the sign for a square root were not invented till the 16th Century and afterwards.

Our guest is award-winning author JOSEPH MAZUR and we discuss he deeply fascinating new book ENLIGHTENING SYMBOLS: A SHORT HISTORY OF MATHEMATICAL NOTATION AND ITS HIDDEN POWERS.
