GRAVITATIONAL FIELDS & DARK MATTER EXPLAINED

A well-researched but sometimes confusing look at gravity and its effects.

A debut science book offers an overview of several aspects of physics theory.

In this volume, Walsh presents concise explanations of the physics of gravity and gravitational fields as well as the nature of dark matter. The short work is divided into two parts, one for each topic, and relies on both established theory and examples to illustrate the concepts—among others, the author explores Einstein’s “man in a carriage,” a way of depicting how people moving at different speeds observe their surroundings. Walsh also uses Newton’s cradle as a method of explaining how kinetic energy is crucial to motion. The book reviews the effects of gravity as they are experienced on Earth before moving into the wider solar system. Kinetic energy is at the core of the volume’s interpretation of the laws of physics. There are many references to “vis viva,” the historical term for the energy of motion, and the work’s conclusion is that humans do indeed exist within a field of kinetic energy. Walsh clearly has a passion for his subject matter, but there are frequent perplexing and jargon-driven sentences (“This example shows us the energy is a result of a particular action we can specify as motion VS action of stored energy to motion”). Much of the prose would benefit from editing for clarity: “Let us note right now that the subject of energies transforming from one form to another is not needed for this discussion, but we have now noted this”; “Kinetic energy is working on, via in a body (under natural action in the universe, Newton’s first law action), and dark matter is working on a body in its area of existence (perhaps not only this).” In the concluding section, the equations demonstrating the connection between Neptune’s orbital speed and its position in the solar system rely on several apparently arbitrary values, making it unclear to readers exactly how Walsh arrives at an entirely reasonable conclusion. It is evident throughout the book that the author understands the physics involved and has deeply researched the subject, but the substance of his knowledge is not effectively conveyed to readers through the text. The volume may be of more value to those with some expertise in the subject, but novices should look elsewhere for an introduction.

A well-researched but sometimes confusing look at gravity and its effects.

THE RIGHT STUFF

Yes: it's high time for a de-romanticized, de-mythified, close-up retelling of the U.S. Space Program's launching—the inside story of those first seven astronauts.

But no: jazzy, jivey, exclamation-pointed, italicized Tom Wolfe "Mr. Overkill" hasn't really got the fight stuff for the job. Admittedly, he covers all the ground. He begins with the competitive, macho world of test pilots from which the astronauts came (thus being grossly overqualified to just sit in a controlled capsule); he follows the choosing of the Seven, the preparations for space flight, the flights themselves, the feelings of the wives; and he presents the breathless press coverage, the sudden celebrity, the glorification. He even throws in some of the technology. But instead of replacing the heroic standard version with the ring of truth, Wolfe merely offers an alternative myth: a surreal, satiric, often cartoony Wolfe-arama that, especially since there isn't a bit of documentation along the way, has one constantly wondering if anything really happened the way Wolfe tells it. His astronauts (referred to as "the brethren" or "The True Brothers") are obsessed with having the "right stuff" that certain blend of guts and smarts that spells pilot success. The Press is a ravenous fool, always referred to as "the eternal Victorian Gent": when Walter Cronkite's voice breaks while reporting a possible astronaut death, "There was the Press the Genteel Gent, coming up with the appropriate emotion. . . live. . . with no prompting whatsoever!" And, most off-puttingly, Wolfe presumes to enter the minds of one and all: he's with near-drowing Gus Grissom ("Cox. . . That face up there!—it's Cox. . . Cox knew how to get people out of here! . . . Cox! . . ."); he's with Betty Grissom angry about not staying at Holiday Inn ("Now. . . they truly owed her"); and, in a crude hatchet-job, he's with John Glenn furious at Al Shepard's being chosen for the first flight, pontificating to the others about their licentious behavior, or holding onto his self-image during his flight ("Oh, yes! I've been here before! And I am immune! I don't get into corners I can't get out of! . . . The Presbyterian Pilot was not about to foul up. His pipeline to dear Lord could not be clearer"). Certainly there's much here that Wolfe is quite right about, much that people will be interested in hearing: the P-R whitewash of Grissom's foul-up, the Life magazine excesses, the inter-astronaut tensions. And, for those who want to give Wolfe the benefit of the doubt throughout, there are emotional reconstructions that are juicily shrill.

But most readers outside the slick urban Wolfe orbit will find credibility fatally undermined by the self-indulgent digressions, the stylistic excesses, and the broadly satiric, anti-All-American stance; and, though The Right Stuff has enough energy, sass, and dirt to attract an audience, it mostly suggests that until Wolfe can put his subject first and his preening writing-persona second, he probably won't be a convincing chronicler of anything much weightier than radical chic.

WHY FISH DON'T EXIST

A STORY OF LOSS, LOVE, AND THE HIDDEN ORDER OF LIFE

A quirky wonder of a book.

A Peabody Award–winning NPR science reporter chronicles the life of a turn-of-the-century scientist and how her quest led to significant revelations about the meaning of order, chaos, and her own existence.

Miller began doing research on David Starr Jordan (1851-1931) to understand how he had managed to carry on after the 1906 San Francisco earthquake destroyed his work. A taxonomist who is credited with discovering “a full fifth of fish known to man in his day,” Jordan had amassed an unparalleled collection of ichthyological specimens. Gathering up all the fish he could save, Jordan sewed the nameplates that had been on the destroyed jars directly onto the fish. His perseverance intrigued the author, who also discusses the struggles she underwent after her affair with a woman ended a heterosexual relationship. Born into an upstate New York farm family, Jordan attended Cornell and then became an itinerant scholar and field researcher until he landed at Indiana University, where his first ichthyological collection was destroyed by lightning. In between this catastrophe and others involving family members’ deaths, he reconstructed his collection. Later, he was appointed as the founding president of Stanford, where he evolved into a Machiavellian figure who trampled on colleagues and sang the praises of eugenics. Miller concludes that Jordan displayed the characteristics of someone who relied on “positive illusions” to rebound from disaster and that his stand on eugenics came from a belief in “a divine hierarchy from bacteria to humans that point[ed]…toward better.” Considering recent research that negates biological hierarchies, the author then suggests that Jordan’s beloved taxonomic category—fish—does not exist. Part biography, part science report, and part meditation on how the chaos that caused Miller’s existential misery could also bring self-acceptance and a loving wife, this unique book is an ingenious celebration of diversity and the mysterious order that underlies all existence.

A quirky wonder of a book.
