The Brat Pack of Quantum Mechanics
Topic: Science 7:45 am EDT, Oct 17, 2008

John Derbyshire:

Wolfgang Pauli had formulated the exclusion principle by the time he was 25. Werner Heisenberg was only 23 when he discovered matrix mechanics and just 25 when he developed the uncertainty principle. Paul Dirac’s reconciliation of quantum mechanics and special relativity came when he was 26. All three eventually received the Nobel Prize for work they had done before the age of 30. Their revolutionary discoveries in the 1920s inspired the term Knabenphysik—boys’ physics—and Segrè describes “the curse of the Knabenphysik, the notion that one should have done something of significance before turning thirty.” The causes of decline are mysterious:

Maybe you stop believing you can change the world, or maybe you realize more quickly that a crazy idea is just that and do not pursue it as vigorously. Maybe you can’t assimilate new material as rapidly as you did when you were younger. Perhaps, having set a new course for physics once, you experience a psychological and intellectual resistance to shifting direction again.

For older physicists—like Einstein, whom the younger generation revered but ignored—it wasn’t easy to keep up. And even for the revolutionaries, the transition from being prodigies to professors was difficult; neither Pauli, Heisenberg, nor Dirac achieved anything nearly as important after turning thirty as they had before.

Alphabet Juice: The Energies, Gists, and Spirits of Letters, Words, and Combinations Thereof; Their Roots, Bones, Innards, Piths, Pips, and Secret Parts, ... With Examples of Their Usage Foul and Savory
Topic: Science 12:58 pm EDT, Oct 13, 2008

After forty years of making a living using words in every medium, print or electronic, except greeting cards, Roy Blount Jr. still can’t get over his ABCs. In Alphabet Juice, he celebrates the juju, the sonic and kinetic energies of letters and their combinations. Blount does not prescribe proper English. The franchise he claims is “over the counter” and concentrates more on questions such as these: Did you know that both mammal and matter derive from baby talk? Have you noticed how wince makes you wince?

Three and a half centuries ago, Sir Thomas Blount produced Blount’s Glossographia, the first dictionary to explore derivations of English words. This Blount’s Glossographia takes that pursuit to other levels. It rejects the standard linguistic notion that the connection between words and their meanings is “arbitrary.” Even the word arbitrary is shown to be no more arbitrary, at its roots, than go-to guy or crackerjack. From sources as venerable as the OED (in which Blount finds an inconsistency, at whisk) and as fresh as Urbandictionary.com (to which Blount has contributed the number-one definition of “alligator arm”), and especially from the author’s own wide-ranging experience, Alphabet Juice derives an organic take on language that is unlike, and more fun than, any other.

The Washington Post has a review.

Fruitless Fall: The Collapse of the Honey Bee and the Coming Agricultural Crisis
Topic: Science 12:58 pm EDT, Oct 13, 2008

Rowan Jacobsen:

With a passion that gives this exploration of colony collapse disorder real buzz, Rowan Jacobsen investigates why 30 billion honeybees—one-quarter of the northern hemisphere's population—vanished by the spring of 2007. He identifies the convergence of culprits—blood-sucking mites, pesticide buildup, viral infections, overused antibiotics, urbanization and climate change—that have led to habitat loss and the destruction of the beautiful mathematics of the hive. Honeybees are undergoing something akin to a nervous breakdown; they aren't pollinating crops as effectively, and production of commercial American honey, already undercut by cheap Chinese imports, is dwindling, even as beekeepers truck stressed honeybees cross-country to pollinate the fields of desperate farmers. Jacobsen pessimistically predicts that our breakfasts will become ... a lot more expensive as the supply of citrus fruits, berries and nuts will inevitably decrease, though he expresses faith that more resilient bees can eventually emerge, perhaps as North American honeybees are crossbred with sturdier Russian queen bees. The author, now tending his own hives, invests solid investigative journalism with a poet's voice to craft a fact-heavy book that soars.

The Trouble with Biodiversity
Topic: Science 12:58 pm EDT, Oct 13, 2008

Life is more varied near the equator. But making sense of that has confounded biologists for 200 years.

Why Current Publication Practices May Distort Science
Topic: Science 12:44 pm EDT, Oct 13, 2008

This essay makes the underlying assumption that scientific information is an economic commodity, and that scientific journals are a medium for its dissemination and exchange. While this exchange system differs from a conventional market in many senses, including the nature of payments, it shares the goal of transferring the commodity (knowledge) from its producers (scientists) to its consumers (other scientists, administrators, physicians, patients, and funding agencies). The function of this system has major consequences. Idealists may be offended that research be compared to widgets, but realists will acknowledge that journals generate revenue; publications are critical in drug development and marketing and to attract venture capital; and publishing defines successful scientific careers. Economic modeling of science may yield important insights.

Rejuvenating the Sun and Avoiding Other Global Catastrophes
Topic: Science 8:28 am EDT, Oct 10, 2008

Just a reminder that it could be worse.

This book investigates the idea that the distant future evolution of our Sun might be controlled (literally, asteroengineered) so that it maintains its present-day energy output rather than becoming a highly luminous and bloated red giant star a process that, if allowed to develop, will destroy all life on Earth. The text outlines how asteroengineering might work in principle and it describes what the future solar system could look like. It also addresses the idea of asteroengineering as a galaxy-wide imperative, explaining why the Earth has never been visited by extraterrestrial travellers in the past.

Icarus at the Edge of Time
Topic: Science 8:18 am EDT, Oct 10, 2008

Brian Greene:

From one of America's leading physicists--a moving and visually stunning futuristic re-imagining of the Icarus fable written for kids and those journeying with them toward a deeper appreciation of the cosmos.

With a minimum of words set on 34 full color pages, Icarus travels not to the sun, but to a black hole, and in so doing poignantly dramatizes one of Einstein's greatest insights.

Unlike anything Brian Greene has previously written, Icarus at the Edge of Time uses the power of story, not pedagogy, to communicate viscerally one small part of the strange reality that has emerged from modern physics. Designed by Chip Kidd, with spectacular images from the Hubble Space Telescope, it's a short story that speaks to curiosity and wisdom in a universe we've only begun to fathom.

From the archive:

Oh! I feel it. I feel the cosmos!

Honest Signals
Topic: Science 7:33 am EDT, Oct  1, 2008

Sandy Pentland:

How can you know when someone is bluffing? Paying attention? Genuinely interested? The answer, writes Sandy Pentland in Honest Signals, is that subtle patterns in how we interact with other people reveal our attitudes toward them. These unconscious social signals are not just a back channel or a complement to our conscious language; they form a separate communication network. Biologically based "honest signaling," evolved from ancient primate signaling mechanisms, offers an unmatched window into our intentions, goals, and values. If we understand this ancient channel of communication, Pentland claims, we can accurately predict the outcomes of situations ranging from job interviews to first dates.

Pentland, an MIT professor, has used a specially designed digital sensor worn like an ID badge—a "sociometer"—to monitor and analyze the back-and-forth patterns of signaling among groups of people. He and his researchers found that this second channel of communication, revolving not around words but around social relations, profoundly influences major decisions in our lives—even though we are largely unaware of it. Pentland presents the scientific background necessary for understanding this form of communication, applies it to examples of group behavior in real organizations, and shows how by "reading" our social networks we can become more successful at pitching an idea, getting a job, or closing a deal. Using this "network intelligence" theory of social signaling, Pentland describes how we can harness the intelligence of our social network to become better managers, workers, and communicators.

Climate Science: Is it currently designed to answer questions?
Topic: Science 7:33 am EDT, Oct  1, 2008

Richard S. Lindzen:

For a variety of inter-related cultural, organizational, and political reasons, progress in climate science and the actual solution of scientific problems in this field have moved at a much slower rate than would normally be possible. Not all these factors are unique to climate science, but the heavy influence of politics has served to amplify the role of the other factors. Such factors as the change in the scientific paradigm from a dialectic opposition between theory and observation to an emphasis on simulation and observational programs, the inordinate growth of administration in universities and the consequent increase in importance of grant overhead, and the hierarchical nature of formal scientific organizations are cosidered. This paper will deal with the origin of the cultural changes and with specific examples of the operation and interaction of these factors. In particular, we will show how political bodies act to control scientific institutions, how scientists adjust both data and even theory to accommodate politically correct positions, and how opposition to these positions is disposed of.
