Here’s a straightforward answer to the question every parent has been asked, and few can answer: How do computers really work? Hillis, the head of Disney’s Imagineering Works, begins by describing a stone etched in a complex pattern, which can be asked questions in a strange language and give profound and useful answers. It sounds like witchcraft, but it is a literally accurate description of a computer chip. As he goes on to show, the internal workings of a computer can be broken down into simple components. His first chapter introduces the reader to the rudiments of Boolean logic and simple electrical circuits. These ideas can be used to build simple computers, such as the author’s own early design of a machine to play tic-tac-toe, or another made from Tinker Toys. The next step in complexity is the development of specific logical functions—And, Or, Invert—that form the basis of almost all computing functions. These concepts are illustrated by the game Rock, Paper, Scissors, converted to digital form. Programming is illustrated with the famous “turtle” programs from the Logo computing language, designed to teach children. In similar manner, Hillis introduces the reader step by step to Turing machines, algorithms, encryption, and other advanced concepts. All this is done without discussions of state-of-the-art hardware or engineering problems; in fact, the author encourages the reader to think in terms of “black box” modulees that can be combined to perform a desired task. One need not know what’s in the box as long as one knows its ultimate function. The final chapters look at issues on the frontiers of computing: machines that learn and adapt, possibly even (in time) machines that can be said to “think.” All this is done elegantly and entertainingly, without a whiff of condescension toward the nontechnical reader. Clear and down-to-earth; even hopeless technophobes should find it enlightening. (Author tour)

From the national correspondent for PBS's MacNeil-Lehrer Newshour: a moving memoir of her youth in the Deep South and her role in desegregating the Univ. of Georgia. The eldest daughter of an army chaplain, Hunter-Gault was born in what she calls the ``first of many places that I would call `my place' ''—the small village of Due West, tucked away in a remote little corner of South Carolina. While her father served in Korea, Hunter-Gault and her mother moved first to Covington, Georgia, and then to Atlanta. In ``L.A.'' (lovely Atlanta), surrounded by her loving family and a close-knit black community, the author enjoyed a happy childhood participating in activities at church and at school, where her intellectual and leadership abilities soon were noticed by both faculty and peers. In high school, Hunter-Gault found herself studying the ``comic-strip character Brenda Starr as I might have studied a journalism textbook, had there been one.'' Determined to be a journalist, she applied to several colleges—all outside of Georgia, for ``to discourage the possibility that a black student would even think of applying to one of those white schools, the state provided money for black students'' to study out of state. Accepted at Michigan's Wayne State, the author was encouraged by local civil-rights leaders to apply, along with another classmate, to the Univ. of Georgia as well. Her application became a test of changing racial attitudes, as well as of the growing strength of the civil-rights movement in the South, and Gault became a national figure as she braved an onslaught of hostilities and harassment to become the first black woman to attend the university. A remarkably generous, fair-minded account of overcoming some of the biggest, and most intractable, obstacles ever deployed by southern racists. (Photographs—not seen.)

Necessarily swift and adumbrative as well as inclusive, focused, and graceful.
A light-speed tour of (mostly) Western poetry, from the 4,000-year-old Gilgamesh to the work of Australian poet Les Murray, who died in 2019.
In the latest entry in the publisher’s Little Histories series, Carey, an emeritus professor at Oxford whose books include What Good Are the Arts? and The Unexpected Professor: An Oxford Life in Books, offers a quick definition of poetry—“relates to language as music relates to noise. It is language made special”—before diving in to poetry’s vast history. In most chapters, the author deals with only a few writers, but as the narrative progresses, he finds himself forced to deal with far more than a handful. In his chapter on 20th-century political poets, for example, he talks about 14 writers in seven pages. Carey displays a determination to inform us about who the best poets were—and what their best poems were. The word “greatest” appears continually; Chaucer was “the greatest medieval English poet,” and Langston Hughes was “the greatest male poet” of the Harlem Renaissance. For readers who need a refresher—or suggestions for the nightstand—Carey provides the best-known names and the most celebrated poems, including Paradise Lost (about which the author has written extensively), “Kubla Khan,” “Ozymandias,” “The Charge of the Light Brigade,” Wordsworth and Coleridge’s Lyrical Ballads, which “changed the course of English poetry.” Carey explains some poetic technique (Hopkins’ “sprung rhythm”) and pauses occasionally to provide autobiographical tidbits—e.g., John Masefield, who wrote the famous “Sea Fever,” “hated the sea.” We learn, as well, about the sexuality of some poets (Auden was bisexual), and, especially later on, Carey discusses the demons that drove some of them, Robert Lowell and Sylvia Plath among them. Refreshingly, he includes many women in the volume—all the way back to Sappho—and has especially kind words for Marianne Moore and Elizabeth Bishop, who share a chapter.
