All of a sudden comes a spate of books glorifying neural networks. Do we sense a paradigm shift here? Down with the old reductionist approach of artificial intelligence? Up with the biologically more relevant parallel processing network models? So it would seem, but don't expect consensus. Unlike other recent writers in the field who argue for a specific theory (e.g., Gerald M. Edelman in Bright Air, Brilliant Fire, p. 297), Jubak (former editor of Venture magazine) provides a broad survey of current work in academia and industry, leaving it up to the reader to judge. Jubak is an enthusiast who's on top of developments in speech and pattern perception, robotics, organizing principles in brain development, and so on—but it's just not easy to convey the structure and behavior of computer networks in which the builders themselves are uncertain about what happens in the ``hidden'' layers connected to an input layer (responding to light signals, for example) and to the output layer (identifying a letter or other pattern). Overall, the models try to emulate features of the human brain in its connectivity and its ability to learn. ``Learning'' is often defined in terms of the Hebb synapse—a strengthening of the connection between neurons that fire together. Some basis for the Hebb synapse is revealed late in the book in the discovery of the NMDA receptor—one of two kinds of receptors at neuronal synapses that may be responsible for long-term potentiation. At this microcosmic level of brain science, we learn, the nerve cell itself may be a master microprocessor computing its behavior from multiple inputs summed over time and space and subject to its own feedback circuits. Jubak's useful if demanding survey reveals that the state of the science is such that the more we know the less we know; but that what the brain does is absolutely thrilling—and beautiful.

BOOK REVIEW
by Jim Jubak
by William Strunk & E.B. White ‧ RELEASE DATE: May 15, 1972
Stricter than, say, Bergen Evans or W3 ("disinterested" means impartial — period), Strunk is in the last analysis...
Privately published by Strunk of Cornell in 1918 and revised by his student E. B. White in 1959, that "little book" is back again with more White updatings.
Stricter than, say, Bergen Evans or W3 ("disinterested" means impartial — period), Strunk is in the last analysis (whoops — "A bankrupt expression") a unique guide (which means "without like or equal").Pub Date: May 15, 1972

by E.T.A. Hoffmann ‧ RELEASE DATE: Oct. 28, 1996
This is not the Nutcracker sweet, as passed on by Tchaikovsky and Marius Petipa. No, this is the original Hoffmann tale of 1816, in which the froth of Christmas revelry occasionally parts to let the dark underside of childhood fantasies and fears peek through. The boundaries between dream and reality fade, just as Godfather Drosselmeier, the Nutcracker's creator, is seen as alternately sinister and jolly. And Italian artist Roberto Innocenti gives an errily realistic air to Marie's dreams, in richly detailed illustrations touched by a mysterious light. A beautiful version of this classic tale, which will captivate adults and children alike. (Nutcracker; $35.00; Oct. 28, 1996; 136 pp.; 0-15-100227-4)
