ONCE BEFORE TIME

A WHOLE STORY OF THE UNIVERSE

The latest effort to make sense of the universe by a young physicist.

In his debut, Bojowald (Physics/Pennsylvania State Univ.) points out that general relativity and quantum mechanics, the two magnificent explanations of physical phenomena, don’t explain everything. For example, solving their equations to describe earlier periods of the universe works beautifully until everything reaches an infinitely small point, the Big Bang singularity, where the temperature of the universe is infinite. Infinities are a no-no in science; their appearance doesn’t necessarily invalidate a theory but reveals that it needs work. The crucial problem is that quantum mechanics describes matter in the universe but says nothing about gravity or space/time, which is the domain of relativity. Bojowald describes 50 years of effort to meld the two into “quantum gravity,” which would clear up major difficulties in cosmology, including what happened during the Big Bang—or whether it happened at all. A consummate researcher, the author works hard to explain his preferred solution, “loop quantum gravity,” with a nod toward the leading rival, string theory. Along the way he delivers updates on current thinking on black holes, dark matter and energy and the fate of the universe, along with digressions into myths, literature and philosophy. Like Brian Greene in The Elegant Universe (2003), Bojowald simplifies a complex subject as much as possible but no further. Those who remember high-school physics or who enjoyed Stephen Hawking’s A Brief History of Time (1988) will have a more satisfying experience.

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

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.

A tiny book, not much bigger than a pamphlet, with huge potential impact.

NO ONE IS TOO SMALL TO MAKE A DIFFERENCE

A collection of articulate, forceful speeches made from September 2018 to September 2019 by the Swedish climate activist who was nominated for a Nobel Peace Prize.

Speaking in such venues as the European and British Parliaments, the French National Assembly, the Austrian World Summit, and the U.N. General Assembly, Thunberg has always been refreshingly—and necessarily—blunt in her demands for action from world leaders who refuse to address climate change. With clarity and unbridled passion, she presents her message that climate change is an emergency that must be addressed immediately, and she fills her speeches with punchy sound bites delivered in her characteristic pull-no-punches style: “I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act.” In speech after speech, to persuade her listeners, she cites uncomfortable, even alarming statistics about global temperature rise and carbon dioxide emissions. Although this inevitably makes the text rather repetitive, the repetition itself has an impact, driving home her point so that no one can fail to understand its importance. Thunberg varies her style for different audiences. Sometimes it is the rousing “our house is on fire” approach; other times she speaks more quietly about herself and her hopes and her dreams. When addressing the U.S. Congress, she knowingly calls to mind the words and deeds of Martin Luther King Jr. and John F. Kennedy. The last speech in the book ends on a note that is both challenging and upbeat: “We are the change and change is coming.” The edition published in Britain earlier this year contained 11 speeches; this updated edition has 16, all worth reading.

A tiny book, not much bigger than a pamphlet, with huge potential impact.
