Not Even Wrong tells a fascinating and complex story about human beings and their attempts to come to grips with perhaps the most intellectually demanding puzzle there is: how does the world work at the most fundamental level and what is the role of mathematics in its description? The author's perspective on this story is unusual since he has worked in both leading physics and mathematics departments and holds very skeptical views about ‘string theory’, the subject that has dominated research in this field for the past twenty years.
