Iran’s nuclear program has generated intense controversy ever since the International Atomic Energy Agency reported in 2003 that Iran was secretly pursuing enrichment activities. Although Iranian officials insist the program is peaceful, many in the international community are skeptical of Iran’s stated aims—and some allege there is no greater nuclear-weapons proliferation danger in the world today.

Nuclear Iran guides readers through the intricate maze of science and secrecy that lies at the heart of Iran’s nuclear ambitions. Writing for the general reader, Jeremy Bernstein brings his knowledge as a physicist to bear on the issues, offering elucidations of the scientific principles and technical hurdles involved in creating nuclear reactors and bombs. His explanations range from the physics of fission to methods of isotope separation to the technologies required for weaponizing fissile uranium and plutonium. Iran’s construction of centrifuges capable of producing weapons-grade uranium has received much media attention, and Bernstein explains how these complex devices work. He intersperses many elements of the human story into his discussions of technology, such as the fact that centrifuges were first invented by German war prisoners working in the Soviet Union.

Nuclear Iran turns a spotlight on the controversial underground uranium-enrichment facility in Natanz and heavy water reactor in Arak, and profiles key figures in the ongoing international trade in weapons technology, including the Pakistani physicist A. Q. Khan. This succinct book is timely reading for anyone who wishes to understand the science behind the international crisis surrounding Iran’s nuclear program.

From molecules to stars, much of the cosmic canvas can be painted in brushstrokes of primary color: the protons, neutrons, and electrons we know so well. But for meticulous detail, we have to dip into exotic hues—leptons, mesons, hadrons, quarks. Bringing particle physics to life as few authors can, Jeremy Bernstein here unveils nature in all its subatomic splendor.

In this graceful account, Bernstein guides us through high-energy physics from the early twentieth century to the present, including such highlights as the newly discovered Higgs boson. Beginning with Ernest Rutherford’s 1911 explanation of the nucleus, a model of atomic structure emerged that sufficed until the 1930s, when new particles began to be theorized and experimentally confirmed. In the postwar period, the subatomic world exploded in a blaze of unexpected findings leading to the theory of the quark, in all its strange and charmed variations. An eyewitness to developments at Harvard University and the Institute for Advanced Study in Princeton, Bernstein laces his story with piquant anecdotes of such luminaries as Wolfgang Pauli, Murray Gell-Mann, and Sheldon Glashow.

Surveying the dizzying landscape of contemporary physics, Bernstein remains optimistic about our ability to comprehend the secrets of the cosmos—even as its mysteries deepen. We now know that over eighty percent of the universe consists of matter we have never identified or detected. A Palette of Particles draws readers into the excitement of a field where the more we discover, the less we seem to know.

Quantum Leaps is a lively, erudite book on a subject that Bernstein has lived with for most of its history. His experience and deep understanding are apparent on every page. Including recollections of encounters with the theory and the people responsible for it, Jeremy Bernstein's account ranges from the cross-pollination of quantum mechanics with Marxist ideology and Christian and Buddhist mysticism to its influence on theater, film, and fiction.
