UNVEILING THE EDGE OF TIME

BLACK HOLES, WHITE HOLES, WORM HOLES

The first half of this latest from prolific English science- writer Gribbin (Cosmic Coincidences, 1989, etc.) is a nice reprise of special and general relativity, complete with credit to some early scientists who thought about dark and dense matter centuries before black holes were named. We learn that 18th-century clergyman and scientist John Michell figured out that a star the size of our solar system and with the same density as the sun would have an escape velocity greater than the speed of light and hence would be invisible. And that in 1801, a German astronomer, Johann von Soldner, surmised that light passing near a star would be bent by gravity and that there might even be a massive body at the center of the Milky Way. The second half of the book is something else again. Here, Gribbin is having fun: Having built a strong case for the existence of black holes, big and little and in between, he goes on to speculate how variations on this theme could lead to time reversal and time travel; give new impetus to "inflationary" theories and the concept of an oscillating universe; and suggest that the Big Bang may be quantized on a Planck scale. Will readers also have fun? Only if they are enamored of science fiction or are followers of those who practice astrophysical cosmology and like to speculate- -Hawking, Sagan, Penrose, Gribbin himself. For these freethinking folk, this is a book that rejoices in paradoxes and delights in reporting that nothing bizarre—baby universes, bubble universes, universe-sized black holes, energy extraction and time travel through wormholes—is denied by the laws of physics.

A SHORT HISTORY OF NEARLY EVERYTHING

Bryson (I'm a Stranger Here Myself, 1999, etc.), a man who knows how to track down an explanation and make it confess, asks the hard questions of science—e.g., how did things get to be the way they are?—and, when possible, provides answers.

As he once went about making English intelligible, Bryson now attempts the same with the great moments of science, both the ideas themselves and their genesis, to resounding success. Piqued by his own ignorance on these matters, he’s egged on even more so by the people who’ve figured out—or think they’ve figured out—such things as what is in the center of the Earth. So he goes exploring, in the library and in company with scientists at work today, to get a grip on a range of topics from subatomic particles to cosmology. The aim is to deliver reports on these subjects in terms anyone can understand, and for the most part, it works. The most difficult is the nonintuitive material—time as part of space, say, or proteins inventing themselves spontaneously, without direction—and the quantum leaps unusual minds have made: as J.B.S. Haldane once put it, “The universe is not only queerer than we suppose; it is queerer than we can suppose.” Mostly, though, Bryson renders clear the evolution of continental drift, atomic structure, singularity, the extinction of the dinosaur, and a mighty host of other subjects in self-contained chapters that can be taken at a bite, rather than read wholesale. He delivers the human-interest angle on the scientists, and he keeps the reader laughing and willing to forge ahead, even over their heads: the human body, for instance, harboring enough energy “to explode with the force of thirty very large hydrogen bombs, assuming you knew how to liberate it and really wished to make a point.”

Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science into perspective.

THE GENIUS OF BIRDS

Science writer Ackerman (Ah-Choo!: The Uncommon Life of Your Common Cold, 2010, etc.) looks at the new science surrounding avian intelligence.

The takeaway: calling someone a birdbrain is a compliment. And in any event, as Ackerman observes early on, “intelligence is a slippery concept, even in our own species, tricky to define and tricky to measure.” Is a bird that uses a rock to break open a clamshell the mental equivalent of a tool-using primate? Perhaps that’s the wrong question, for birds are so unlike humans that “it’s difficult for us to fully appreciate their mental capabilities,” given that they’re really just small, feathered dinosaurs who inhabit a wholly different world from our once-arboreal and now terrestrial one. Crows and other corvids have gotten all the good publicity related to bird intelligence in recent years, but Ackerman, who does allow that some birds are brighter than others, points favorably to the much-despised pigeon as an animal that “can remember hundreds of different objects for long periods of time, discriminate between different painting styles, and figure out where it’s going, even when displaced from familiar territory by hundreds of miles.” Not bad for a critter best known for bespattering statues in public parks. Ackerman travels far afield to places such as Barbados and New Caledonia to study such matters as memory, communication, and decision-making, the last largely based on visual cues—though, as she notes, birds also draw ably on other senses, including smell, which in turn opens up insight onto “a weird evolutionary paradox that scientists have puzzled over for more than a decade”—a matter of the geometry of, yes, the bird brain.

Ackerman writes with a light but assured touch, her prose rich in fact but economical in delivering it. Fans of birds in all their diversity will want to read this one.
