THE UNIVERSE AT MIDNIGHT

NEW DISCOVERIES ILLUMINATE THE HIDDEN COSMOS

Cosmological speculations live or die on the observations of astronomers. Here, a Harvard-trained astronomer summarizes the current relations between the two disciplines.

Croswell (See the Stars, 2000) starts with the most basic observation of all, the darkness of the night sky. Explaining this quotidian phenomenon taxed the ingenuity of theorists for centuries; in an infinite universe, the night sky ought to be uniformly light. The answer provided by modern cosmology combines the finite age of the universe and the finite speed of light; we cannot see stars so far away that their light has not had time to reach us. This raises the issue of the age of the universe, a topic of considerable controversy. Until the early 1960s, some astronomers postulated that the universe was of infinite age. Confirmation of the Big Bang theory overthrew that assumption, but the exact age of the universe remained uncertain, with some calculations suggesting that the universe was younger than its oldest stars. Such paradoxes have driven cosmologists to propose a universe composed largely of invisible, perhaps extremely strange, materials. No known subatomic particles, dark stars, nor black holes seem to account for the missing mass. Just as strange is the cosmological principle (i.e., a force that arises in empty space and drives the expansion of the universe), which Einstein first proposed, then rejected as “my greatest blunder.” Current models describe a universe 14 billion years old, destined to expand forever. Croswell has a knack for creating memorable portraits of the scientists who figure in his account, and a reader will come away from him not only with a clear grasp of the current theories of our universe’s past and probable future, but a good notion of the men and women who have contributed to our understanding of it.

A solid, well-written summary of modern cosmology.

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.
