George Johnson

Recounts the story of Radcliffe-educated Henrietta Swan Leavitt, who in the face of ill health and progressive hearing loss discovered a new law that enabled astronomers to use variable stars in order to measure the universe, a finding that solved a key scientific mystery and enabled important breakthroughs. Reprint.

The newest Pentium chip powering PCs and laptops contains 40 million electronic switches packed onto a piece of silicon about the size of a thumbnail. Several years from now, if this incredible shrinking continues, a single chip will hold a billion switches, then a trillion.

In this remarkably illustrative and thoroughly accessible look at one of the most intriguing frontiers in science and computers, award-winning New York Times writer George Johnson reveals the fascinating world of quantum computing--the holy grail of super computers where the computing power of single atoms is harnassed to create machines capable of almost unimaginable calculations in the blink of an eye. As computer chips continue to shrink in size, scientists anticipate the end of the road: A computer in which each switch is comprised of a single atom. Such a device would operate under a different set of physical laws: The laws of quantum mechanics. Johnson gently leads the curious outsider through the surprisingly simple ideas needed to understand this dream, discussing the current state of the revolution, and ultimately assessing the awesome power these machines could have to change our world.

No scientist has done more to shape our understanding of the universe than Murray Gell-Mann, the Nobel Prize-winner considered by many colleagues to be the most brilliant physicist of his generation. His discovery of the quark and the Eightfold Way were cornerstones for all that followed in particle physics, the effort to understand the very stuff of creation, In this, the first biography of Gell-Mann, George Johnson tells the story of a remarkable life.

With a New Afterword "Our knowledge of fundamental physics contains not one fruitful idea that does not carry the name of Murray Gell-Mann."--Richard Feynman Acclaimed science writer George Johnson brings his formidable reporting skills to the first biography of Nobel Prize-winner Murray Gell-Mann, the brilliant, irascible man who revolutionized modern particle physics with his models of the quark and the Eightfold Way. Born into a Jewish immigrant family on New York's East 14th Street, Gell-Mann's prodigious talent was evident from an early age--he entered Yale at 15, completed his Ph.D. at 21, and was soon identifying the structures of the world's smallest components and illuminating the elegant symmetries of the universe. Beautifully balanced in its portrayal of an extraordinary and difficult man, interpreting the concepts of advanced physics with scrupulous clarity and simplicity, Strange Beauty is a tour-de-force of both science writing and biography.

Are there really laws governing the universe? Or is the order we see a mere artifact of the way evolution wired the brain? And is what we call science only a set of myths in which quarks, DNA, and information fill the role once occupied by gods? These questions lie at the heart of George Johnson's audacious exploration of the border between science and religion, cosmic accident and timeless law. Northern New Mexico is home both to the most provocative new enterprises in quantum physics, information science, and the evolution of complexity and to the cosmologies of the Tewa Indians and the Catholic Penitentes. As it draws the reader into this landscape, juxtaposing the systems of belief that have taken root there, Fire in the Mind into a gripping intellectual adventure story that compels us to ask where science ends and religion begins. "A must for all those seriously interested in the key ideas at the frontier of scientific discourse."--Paul Davies

Even as you read these words, a tiny portion of your brain is physically changing. New connections are being sprouted--a circuit that will create a stab of recognition if you encounter the words again. That is one of the theories of memory presented in this intriguing and splendidly readable book, which distills three researchers' inquiries into the processes that enable us to recognize a face that has aged ten years or remember a melody for decades. Ranging from experiments performed on the "wetware" of the brain to attempts to re-create human cognition in computers, In the Palaces of Memory is science writing at its most exciting.
