This is a classic history of mathematics and is surprisingly readable considering it was first published in 1912. It covers math from ancient times up to the late 19th century. It was interesting to read about how math developed down through the centuries, and who the famous mathematicians were and their contributions. I was most in interested in developments since the Renaissance, but I also enjoyed the author's coverage of the Middle Ages and Arabic contributions to algebra. For example, you'll learn about Al-Khwarizmi, Abu-Kamil, and Al Karaji. In the Middle Ages there was Leonardo Fibonacci of Pisa (who gave his name to the famous fibonacci series), who lived in the 13th century (not to be confused with da Vinci who lived later), and was so renowned for his abilities that a competition was once staged by the Holy Roman Emperor to demonstrate his prowess. In fact, these sorts of math contests were quite common in the Middle Ages, which I didn't know about. Three questions were posed, such as give a number that when increased or decreased by 5 remains a square, and Leonardo was the only contestant to get all three right. Leonardo also was one of the first to introduce the Hindu/Arabic number system into Europe. He wrote a number of books, of which several survive today, which made him a celebrity as much for his writing talents as for his mathematical abilities during his lifetime, and the true extent of his contributions wasn't recognized until recent times. He is considered the most important mathematical theorist after Diophantus of Alexandria until Fermat in the 17th century--a span of 2000 years. But he is only one of hundreds of important mathematicians whose contributions are discussed. This book is still a very readable classic history that is still a valuable resource on the subject almost 100 years later.
