During the summer of 1959, Madeleine L’Engle and her family embarked on a cross-country road trip. At night, after the children had gone to bed, she read books of higher math and physics by flashlight. As she recalled in “How Long Is a Book?,” a lecture from the early 1970s, she was seeking a light in the dark: “Not just to learn the various theories of the creation of the universe, the theories of relativity, of quantum [mechanics], but because in the writing of Sir James Jeans, of Einstein, Planck, I got a vision of a universe in which I could believe in God.”
