What is the author's style in The Universe in a Nutshell by Stephen William Hawking?

While Hawking understands physics at an unparalleled level, he has a passion for communicating its ideas to the public. He also has wit and charm, often using puns and poking fun at himself. Hawking is rarely political and seems to have no particular ax to grind, save his philosophy of science and the theological implications of his no boundary condition.
