The scientific status of VSL remains uncertain, but its creator’s account of his investigations is irresistible.
A brash young cosmologist describes his attempts to redefine one of the keystones of relativity.
Magueijo (Theoretical Physics/Imperial College, London) is no crackpot, although many of his colleagues thought so when he suggested a variable speed of light (VSL) as an answer to problems in the Big Bang theory of the origin of our universe. VSL verges on heresy; relativity, which states that the speed of light in a vacuum is constant, has been verified by numerous experiments since its postulation by Einstein in 1905. But while the Big Bang is a direct corollary of relativity, the uniformity of the visible universe is difficult to explain if the speed of light cannot be exceeded. Nor does relativity provide a bridge between the large-scale structure of the universe and the quantum-level structure of matter. Into this theoretical vacuum have flooded superstrings, loops, branes, and all the other hopeful doctrines of recent physics, each eagerly promoted by its advocates. The newest of the new is VSL, which now appears to have some observational support. Having overcome major hurdles on the way to getting his theories published, Magueijo makes clear his contempt for the scientific gatekeepers who determine whose work will appear in which prestigious journal, whose will be rewarded with grants and tenure, and whose cast beyond the pale of science. Thus the work reads like a battle report, with high praise for supporters and little sympathy wasted on opponents. Combined with his position as an outsider in the British science establishment (though educated at Cambridge, he was born in Portugal), Magueijo's obvious lack of interest in pretending to be polite to those he has identified as enemies makes this one of the more scathing scientific memoirs of recent years.

An intriguing meditation on the nature of the universe and our attempts to understand it that should appeal to both...
Italian theoretical physicist Rovelli (General Relativity: The Most Beautiful of Theories, 2015, etc.) shares his thoughts on the broader scientific and philosophical implications of the great revolution that has taken place over the past century.
These seven lessons, which first appeared as articles in the Sunday supplement of the Italian newspaper Sole 24 Ore, are addressed to readers with little knowledge of physics. In less than 100 pages, the author, who teaches physics in both France and the United States, cogently covers the great accomplishments of the past and the open questions still baffling physicists today. In the first lesson, he focuses on Einstein's theory of general relativity. He describes Einstein's recognition that gravity "is not diffused through space [but] is that space itself" as "a stroke of pure genius." In the second lesson, Rovelli deals with the puzzling features of quantum physics that challenge our picture of reality. In the remaining sections, the author introduces the constant fluctuations of atoms, the granular nature of space, and more. "It is hardly surprising that there are more things in heaven and earth, dear reader, than have been dreamed of in our philosophy—or in our physics,” he writes. Rovelli also discusses the issues raised in loop quantum gravity, a theory that he co-developed. These issues lead to his extraordinary claim that the passage of time is not fundamental but rather derived from the granular nature of space. The author suggests that there have been two separate pathways throughout human history: mythology and the accumulation of knowledge through observation. He believes that scientists today share the same curiosity about nature exhibited by early man.
An intriguing meditation on the nature of the universe and our attempts to understand it that should appeal to both scientists and general readers.Pub Date: March 1, 2016

Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science...
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.Pub Date: May 6, 2003
