The real news about “The Grand Design,” however, isn’t Mr. Hawking’s supposed jettisoning of God, information that will surprise no one who has followed his work closely. The real news about “The Grand Design” is how disappointingly tinny and inelegant it is. The spare and earnest voice that Mr. Hawking employed with such appeal in “A Brief History of Time” has been replaced here by one that is alternately condescending, as if he were Mr. Rogers explaining rain clouds to toddlers, and impenetrable.
“The Grand Design” is packed with grating yuks. “If you think it is hard to get humans to follow traffic laws,” we read, “imagine convincing an asteroid to move along an ellipse.” (Oh, my.)
What I find unfair is that he says the book is "packed with grating yuks" and then gives us one example that isn't particularly grating. I find his commentary, "oh, my" (don't leave out that comma, smart guy!) much more grating than the joke itself. I understand that the there is limited room in the review for other examples, but if you are going to assert that something is "packed" with something awful you need to provide more evidence for the reader. Otherwise leave out the assertion.
