The Reaction to the Book by James Hannon

"I've read many, many other books on medieval science," says author. "But the thing I loved about your book was that it made me really understand what they were doing" Some people have said he spends too much time talking about mathematics and not enough astronomy. But his priority is to show how complex science was in the Middle Ages,. In order to do that, he had to take people to the brink of 'really not understanding' them.
