## SIDELIGHTS:

Amir D. Aczel is a mathematician who writes about math, physics, and astronomy for general readers. His books blend historical anecdote, character studies, and hard science to explain such concepts as probability theory, Fermat's Last Theorem, and Einstein's cosmological constant, to those who are curious—if unskilled—in higher math. "For one practiced in dealing with numbers, Amir Aczel certainly has a way with words," observed Jeanette Brown in *Astronomy.* Brown added that Aczel's books present "a beautiful marriage of mathematics and prose." In *Discover* magazine, Jeffrey Winters wrote: "At a time when so many popular physics books avoid equations and fudge mathematical explanations, Aczel wants to delve deep into the mathematics. He believes—as Einstein did—it is in fact the underlying mathematics that makes the universe elegant."

Aczel was best known as a theoretical statistician until the mid-1990s, when he published *Fermat's Last Theorem: Unlocking the Secret of an Ancient Mathematical Problem,* a study of breakthrough work done on a previously unsolved 300-year-old theorem. Aczel once told *CA:* "I write to express myself. I am interested in great nonfiction that tells a true story in an exciting, engaging way. I work late into the night, almost every night. I compose entire chapters in my head, then write them down with very few revisions. I use no book outline, but rather let the story tell itself in the most natural way. If a story doesn't flow, it is not worth telling. *Fermat's Last Theorem* had many stories in it, at different levels: the great problem, unsolved for 300 years, the life stories of the mathematicians who contributed to the final proof, and the intrigue—the human drama."

The success of that work led to one of Aczel's best-known books, *Probability 1: Why There Must Be Intelligent Life in the Universe.* The book's topic and title were originally proposed by Dr. Carl Sagan, but Sagan died before he could begin the project. Aczel took up the challenge, and his book expands upon the theories proposed by astronomer Frank Drake in 1961. "In essence," wrote *New York Times Book Review* correspondent John Durant, "*Probability 1* is a review of Drake's equation in the light of scientific evidence. Aczel argues convincingly that the number of planets suitable for life is extremely large." He bolsters his arguments with information about recent discoveries of planets orbiting other stars, the latest investigations into the possibility of life on Mars and on at least one of Jupiter's moons, and with the facts of biology and evolution on Earth. His final argument, however, is a purely mathematical one: given the size of the universe, the number of stars and galaxies, the probability of *intelligent* extraterrestrial life is one-hundred percent.

Critics were mixed in their assessment of *Probability 1.* Durant explained: "Statistics are extremely powerful and important, and Aczel is a very clear and capable exponent of them. But statistics cannot substitute for empirical knowledge about the way the universe behaves." Jeanette Brown, on the other hand, concluded: "Before reading Aczel's book you may find it easy to shrug off his conclusions. After you've finished *Probability 1,* you may find it harder to do so."

In *God's Equation: Einstein, Relativity, and the Expanding Universe,* Aczel demonstrates that the cosmological constant, discovered and then discounted by Albert Einstein, has once again become an important aspect of the general theory of the behavior of the universe. The book not only discusses the physics behind the expanding universe, but also details Einstein's genius and his working methods during his most prolific period as a physicist/astronomer. "*God's Equation* is not just a retelling of breakthroughs in early twentieth century physics," commented Winters. "Aczel makes it a study of the intersection of mathematics and the physical world." *Booklist* correspondent Bryce Christensen called *God's Equation* "one of the most exciting scientific detective stories ever told," and "a marvelous distillation of epoch-making science."

With *The Mystery of the Aleph: Mathematics, the Kabbalah, and the Search for Infinity,* Aczel turns to the history of the concept of infinity for inspiration, looking at early concepts and ultimately focusing on the life of the nineteenth-century mathematician Georg Cantor, who picked the aleph, the first letter of the Hebrew alphabet, as the symbol for infinity. So involved was Cantor in his search for a mathematical rendering of infinity that he ultimately lost his mind. (Experts now think he may have been bipolar.) Writing in *Booklist,* Bryce Christensen noted that Aczel "penetrates to the human drama behind the formulas" in this "engrossing story of a man and an idea." Likewise, a reviewer for *Publishers Weekly* found *The Mystery of the Aleph* a "compact and fascinating work of mathematical popularization." Richard Bernstein, writing in the *New York Times,* had a more mixed assessment of the same work. Noting the difficulty of explaining complex mathematics to the lay reader, Bernstein called Aczel's book "highly enjoyable and frustrating at the same time." However, Laurence Marschall, in a review for *Sciences,* had no such reservations, commenting that Aczel "serves as an expert guide on Cantor's voyage to the far reaches of abstraction."

Aczel's 2001 work, *The Riddle of the Compass,* was easier on readers, containing no mathematics at all. Instead, Aczel presents a history of the instrument that made ocean exploration possible, tracing conflicting stories of the origin of the compass to China and to Italy, where one Flavio Gioia supposedly invented it around 1300. Gilbert Taylor, writing in *Booklist,* found this a "flowing account," as well as a "delightful, wide-ranging ramble." Further praise came from the *New York Times* reviewer Bernstein, who felt Aczel "shows his usual accessibility as he explores the origins and significance of the world's most important navigational tool."

From science history, Aczel once again returned to the more demanding realms of advanced mathematics and quantum theory with *Entanglement: The Greatest Mystery in Physics,* an exposition and history of what is known in physics as entanglement theory. The theory states that particles can become entangled with one another, so that, even if separated by great distance, there is an instantaneous change in both if one of the partners experiences a change. Albert Einstein once called this notion "spooky," and since the 1960s it has engendered major research into how such a theory could be used for such things as teleportation. Aczel examines the history of the theory as well as the lives of various scientists connected with it in this "accessible entry into this concept of quantum physics," as a reviewer for *Publishers Weekly* termed the book.

Aczel presents more science history in *Pendulum: Leon Foucault and the Triumph of Science,* the story of the French scientist who proved that the Earth rotated on its axis by setting up a pendulum in the cellar of his mother's house. Foucault, who was a dropout from medical school and did not have a university degree, had to battle the French scientific establishment in order for his controversial findings to finally gain acceptance. Aczel provides "a terrific page-turner that captures the essence of the personalities of the story while clearly expounding on the scientific principles," according to *Library Journal* critic Denise Hamilton. The author portrays Parisian society of the Second Empire as well as the science behind Foucault's discovery. Gilbert Taylor, writing in *Booklist,* suggested that *Pendulum* "will keep science buffs thoroughly entertained," while a *Kirkus Reviews* critic found the same book a "good summary of an important era in science and one of its underrated stars."

Statistics and probability are at the heart of Aczel's 2004 book *Chance: A Guide to Gambling, Love, the Stock Market, and Just about Everything Else,* in which the author examines the theory of probability and also offers illustrative "amusing whimsies," as Taylor noted in *Booklist.* Aczel gives advice—based on probability—from picking the right mate to beating the odds at Las Vegas. Taylor concluded that *Chance* was one more title in Aczel's "winning track record of popularizing science." Further praise came from a *Kirkus Reviews* critic who termed the book "an entertaining introduction to one of the most universally relevant and most widely misunderstood branches of mathematics." Similarly, a *Publishers Weekly* reviewer concluded that Aczel's "light touch generally makes probability come alive."

Aczel turned again to science history with his 2005 title *Descartes' Secret Notebook: A True Tale of Mathematics, Mysticism, and the Quest to Understand the Universe,* a "splendid study about the French philosopher and mathematician," according to a *Publishers Weekly* contributor. Aczel here focuses on a secret notebook Rene Descartes, the founder of modern geometry, kept, written in code. Aczel's examination of the fragments remaining from that notebook provides a tale that is "part historical sketch, part biography and part detective story," as the *Publishers Weekly* reviewer further noted. In the telling, Aczel identifies a mystical and occult side to Descartes, a member of the Rosicrucians, and how this mysticism influenced Descartes' mathematical as well as philosophical work. Taylor, writing in *Booklist,* concluded that "Aczel's appeal … will draw fans to his new work." Further adventures in mathematics are offered in the 2006 title *The Artist and the Mathematician: The Story of Nicolas Bourbaki, the Genius Mathematician Who Never Lived.* Aczel tells the story of Bourbaki, a fictional persona created by a group of French mathematicians in the 1920s. These mathematicians published over forty volumes detailing what became known in the United States as "new math." Aczel explains the mathematics and provides character sketches for some of the better known members of the group, such as Andre Well and Alexandre Grothendieck. A critic for *Kirkus Reviews* found this a "fascinating topic, despite the author's sometimes plodding approach." Similar criticism came from a *Publishers Weekly* reviewer who thought the "diffuse" narrative "strains to pull its disparate parts into a satisfactory whole." A higher assessment of the book came from *Library Journal* contributor Ian Gordon, who stated: "Aczel paints a clear picture of the Bourbaki movement and how it has influenced the way mathematics should be discussed and learned."
