The book opens up a world of fact and science and mathematics in a way that finds the spiritual and the metaphysical, the political and the philosophical, lurking in the midst of numbers and measurements and calculations.... Hales engages us both emotionally and intellectually. This is creative nonfiction at its best, this artful union of fact and experience and memory.... Line by line, the writing is wonderful, and individual sections are as fine as any from writers such as Edward Abbey or Annie Dillard. - Lee Martin, author of From Our House: A Memoir
