Book Review: Packing for Mars: The Curious Science of Life in the Void
Packing for Mars: The Curious Science of Life in the Void . Space is a world devoid of the things we need to live and thrive: air, gravity, hot showers, fresh produce, privacy, beer. Space exploration is in some ways an exploration of what it means to be human. How much can a person give up? How much weirdness can they take? What happens to you when you can’t walk for a year? have sex? smell flowers? What happens if you vomit in your helmet during a space walk? Is it possible for the human body to survive a bailout at 17,000 miles per hour? To answer these questions, space agencies set up all manner of quizzical and startlingly bizarre space simulations. As Mary Roach discovers, it’s possible to preview space without ever leaving Earth. From the space shuttle training toilet to a crash test of NASA’s new space capsule (cadaver filling in for astronaut), Roach takes us on a surreally entertaining trip into the science of life in space and space on Earth.

Book Review: The Wave: In Pursuit of the Rogues, Freaks and Giants of the Ocean

Book Review: The Wave: In Pursuit of the Rogues, Freaks and Giants of the Ocean
The Wave: In Pursuit of the Rogues, Freaks and Giants of the Ocean . For centuries, mariners have spun tales of gargantuan waves, 100-feet high or taller. Until recently scientists dis­missed these stories—waves that high would seem to violate the laws of physics. But in the past few decades, as a startling number of ships vanished and new evidence has emerged, oceanographers realized something scary was brewing in the planet’s waters. They found their proof in February 2000, when a British research vessel was trapped in a vortex of impossibly mammoth waves in the North Sea—including several that approached 100 feet.

As scientists scramble to understand this phenomenon, others view the giant waves as the ultimate challenge. These are extreme surfers who fly around the world trying to ride the ocean’s most destructive monsters. The pioneer of extreme surfing is the legendary Laird Hamilton, who, with a group of friends in Hawaii, figured out how to board suicidally large waves of 70 and 80 feet. Casey follows this unique tribe of peo­ple as they seek to conquer the holy grail of their sport, a 100­-foot wave.

In this mesmerizing account, the exploits of Hamilton and his fellow surfers are juxtaposed against scientists’ urgent efforts to understand the destructive powers of waves—from the tsunami that wiped out 250,000 people in the Pacific in 2004 to the 1,740-foot-wave that recently leveled part of the Alaskan coast.

Like Jon Krakauer’s Into Thin Air, The Wave brilliantly portrays human beings confronting nature at its most ferocious.

Book Review: Flatland: A Romance of Many Dimensions

Book Review: Flatland: A Romance of Many Dimensions
Flatland: A Romance of Many Dimensions . Flatland is one of the very few novels about math and philosophy that can appeal to almost any layperson. Published in 1880, this short fantasy takes us to a completely flat world of two physical dimensions where all the inhabitants are geometric shapes, and who think the planar world of length and width that they know is all there is. But one inhabitant discovers the existence of a third physical dimension, enabling him to finally grasp the concept of a fourth dimension. Watching our Flatland narrator, we begin to get an idea of the limitations of our own assumptions about reality, and we start to learn how to think about the confusing problem of higher dimensions. The book is also quite a funny satire on society and class distinctions of Victorian England.

Book Review: The Fabric of the Cosmos: Space, Time, and the Texture of Reality

Book Review: The Fabric of the Cosmos: Space, Time, and the Texture of Reality
The Fabric of the Cosmos: Space, Time, and the Texture of Reality . As a boy, Brian Greene read Albert Camus’ The Myth of Sisyphus and was transformed. Camus, in Greene’s paraphrase, insisted that the hero triumphs “by relinquishing everything beyond immediate experience.” After wrestling with this idea, however, Greene rejected Camus and realized that his true idols were physicists; scientists who struggled “to assess life and to experience the universe at all possible levels, not just those that happened to be accessible to our frail human senses.” His driving question in The Fabric of the Cosmos, then, is fundamental: “What is reality?” Over sixteen chapters, he traces the evolving human understanding of the substrate of the universe, from classical physics to ten-dimensional M-Theory.

Assuming an audience of non-specialists, Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. For the most part, he succeeds. His language reflects a deep passion for science and a gift for translating concepts into poetic images. When explaining, for example, the inability to see the higher dimensions inherent in string theory, Greene writes: “We don’t see them because of the way we see…like an ant walking along a lily pad…we could be floating within a grand, expansive, higher-dimensional space.”

For Greene, Rhodes Scholar and professor of physics and mathematics at Columbia University, speculative science is not always as thorough and successful. His discussion of teleportation, for example, introduces and then quickly tables a valuable philosophical probing of identity. The paradoxes of time travel, however, are treated with greater depth, and his vision of life in a three-brane universe is compelling and–to use his description for quantum reality–”weird.”

In the final pages Greene turns from science fiction back to the fringes of science fact, and he returns with rigor to frame discoveries likely to be made in the coming decades. “We are, most definitely, still wandering in the jungle,” he concludes. Thanks to Greene, though, some of the underbrush has been cleared.

Book Review: The 4 Percent Universe: Dark Matter, Dark Energy, and the Race to Discover the Rest of Reality

The 4 Percent Universe: Dark Matter, Dark Energy, and the Race to Discover the Rest of Reality
The 4 Percent Universe: Dark Matter, Dark Energy, and the Race to Discover the Rest of Reality. In the past few years, a handful of scientists have been racing to explain a disturbing aspect of our universe: only 4 percent of it consists of the matter that makes up you, me, our books, and every planet, star, and galaxy. The rest—96 percent of the universe—is completely unknown.

Richard Panek tells the dramatic story of how scientists reached this cosmos-shattering conclusion, and what they’re doing to find this “dark” matter and an even more bizarre substance called dark energy. This is perhaps the greatest mystery in all of science, and solving it will bring fame, funding, and certainly a Nobel Prize. Based on in-depth, on-site reporting and hundreds of interviews–with everyone from Berkeley’s feisty Saul Perlmutter and Johns Hopkins’s meticulous Adam Riess to the quietly revolutionary Vera Rubin–the book offers an intimate portrait of the bitter rivalries and fruitful collaborations, the eureka moments and blind alleys, that have fueled their search, redefined science, and reinvented the universe.

The stakes couldn’t be higher. Our view of the cosmos is profoundly wrong, and Copernicus was only the beginning: not just Earth, but all common matter is a marginal part of existence. Panek’s fast-paced narrative, filled with behind-the-scenes details, brings this epic story to life for the very first time.
