Greene styles The Elegant Universe to make the reader feel as if they're in a lecture hall. He is never condescending toward the reader, and takes extra time to explain more complicated points. Greene builds excitement as he approaches the latter chapters, which contain the more recent developments of string theory, and it is apparent that Greene and the physicist community are anxiously awaiting the next breakthrough. Greene's tone is akin to a patient teacher: he has a full understanding of the subject matter, and is enthusiastic about sharing his knowledge.
