This book presents cutting-edge research advances in the rapidly growing areas of nanoantennas and plasmonics as well as their related enabling technologies and applications. It provides a comprehensive treatment of the field on subjects ranging from fundamental theoretical principles and new technological developments, to state-of-the-art device design, as well as examples encompassing a wide range of related sub-areas. The content of the book also covers highly-directive nanoantennas, all-dielectric and tuneable/reconfigurable devices, metasurface optical components, and other related topics.

The rapid evolution of integrated circuit technology has brought with it many new materials and processing steps at the nano-scale which boost the electrical performance of devices, resulting in faster and more functionally-complex electronics. However, working at this reduced scale can bring second order effects that degrade efficiency and reliability.

Aquinas’ first proof for God’s existence is usually interpreted as a metaphysical argument immune to any objections coming from empirical science. Connections to Aquinas’ own historical understanding of physics and cosmology are ignored or downplayed. Nature and Nature's God proposes a natural philosophical interpretation of Aquinas’ argument more sensitive to the broader context of Aquinas’ work and yielding a more historically accurate account of the argument. Paradoxically, the book also shows that, on such an interpretation, Aquinas’ argument is not only consistent with modern science, but actually confirmed by the history of science, from classical mechanics through 19th century thermodynamics to contemporary cosmology. The first part of the book considers Aquinas’ argument in its historical context, exploring the key principles that everything in motion is moved by something else and that an infinite regress of causes is impossible. The structure of the First Way is analyzed and the argument is connected both with Aquinas’ Third Way—a new interpretation of which is also proposed—and Aquinas’ second proof from motion in the Summa contra Gentiles. To complete the account of what natural philosophy—prior to metaphysics—can demonstrate about God, a chapter on Aquinas’ teleological argument (the Fifth Way) is also included. The second part of the book tracks the history of modern science from Copernicus to today, showing how Aquinas’ argument fared at each major turn. The first chapter shows how Newton’s understanding of inertia and conservation of momentum supports the idea that motion cannot continue forever without God’s causality, and integrates a modern understanding of inertia and gravity with the principles of Thomistic natural philosophy. The second chapter considers the first and second laws of thermodynamics, showing how they too support Aquinas’ contention that motion cannot continue forever without God’s causality. This chapter also discusses statistical mechanics and contemporary cosmology, demonstrating that science continues to support Aquinas’ unmoved mover argument. The final chapter turns to modern biology as well as cosmological fine-tuning to show that modern science also continues to support Aquinas’ teleological argument. The result is not only a satisfying defense of Aquinas’ natural philosophical proofs for God’s existence, but a primer on the broader project of integrating Thomistic natural philosophy with modern science.

The astonishing science of neutron stars and the stories of the scientists who study them.

Neutron stars are as bewildering as they are elusive. The remnants of exploded stellar giants, they are tiny, merely twenty kilometers across, and incredibly dense. One teaspoon of a neutron star would weigh several million tons. They can spin up to a thousand times per second, they possess the strongest magnetic fields known in nature, and they may be the source of the most powerful explosions in the universe. Through vivid storytelling and on-site reporting from observatories all over the world, Neutron Stars offers an engaging account of these still-mysterious objects.

Award-winning science journalist Katia Moskvitch takes readers from the vast Atacama Desert to the arid plains of South Africa to visit the magnificent radio telescopes and brilliant scientists responsible for our knowledge of neutron stars. She recounts the exhilarating discoveries, frustrating disappointments, and heated controversies of the past several decades and explains cutting-edge research into such phenomena as colliding neutron stars and fast radio bursts: extremely powerful but ultra-short flashes in space that scientists are still struggling to understand. She also shows how neutron stars have advanced our broader understanding of the universe—shedding light on topics such as dark matter, black holes, general relativity, and the origins of heavy elements like gold and platinum—and how we might one day use these cosmic beacons to guide interstellar travel.

With clarity and passion, Moskvitch describes what we are learning at the boundaries of astronomy, where stars have life beyond death.

It is the end of an historical epoch, but to an old professor of physics, Victor Jakob, sitting in his unlighted study, eating dubious bread with jam made from turnips, it is the end of a way of thinking in his own subject. Younger men have challenged the classical world picture of physics and are looking forward to observational tests of Einstein’s new theory of relativity as well as the creation of a quantum mechanics of the atom. It is a time of both apprehension and hope.

In this remarkable book, the reader literally inhabits the mind of a scientist while Professor Jakob meditates on the discoveries of the past fifty years and reviews his own life and career—his scientific ambitions and his record of small successes. He recalls the great men who taught or inspired him: Helmholtz, Hertz, Maxwell, Planck, and above all Paul Drude, whose life and mind exemplified the classical virtues of proportion, harmony, and grace that Jakob reveres. In Drude’s shocking and unexpected suicide, we see reflected Jakob’s own bewilderment and loss of bearings as his once secure world comes to an end in the horrors of the war and in the cultural fragmentation wrought by twentieth-century modernism. His attempt to come to terms with himself, with his life in science, and with his spiritual legacy will affect deeply everyone who cares about the fragile structures of civilization that must fall before the onrush of progress.

On the fiftieth anniversary of Hiroshima, Nobel-winning physicist Hans Bethe called on his fellow scientists to stop working on weapons of mass destruction. What drove Bethe, the head of Theoretical Physics at Los Alamos during the Manhattan Project, to renounce the weaponry he had once worked so tirelessly to create? That is one of the questions answered by Nuclear Forces, a riveting biography of Bethe’s early life and development as both a scientist and a man of principle.

As Silvan Schweber follows Bethe from his childhood in Germany, to laboratories in Italy and England, and on to Cornell University, he shows how these differing environments were reflected in the kind of physics Bethe produced. Many of the young quantum physicists in the 1930s, including Bethe, had Jewish roots, and Schweber considers how Liberal Judaism in Germany helps explain their remarkable contributions. A portrait emerges of a man whose strategy for staying on top of a deeply hierarchical field was to tackle only those problems he knew he could solve.

Bethe’s emotional maturation was shaped by his father and by two women of Jewish background: his overly possessive mother and his wife, who would later serve as an ethical touchstone during the turbulent years he spent designing nuclear bombs. Situating Bethe in the context of the various communities where he worked, Schweber provides a full picture of prewar developments in physics that changed the modern world, and of a scientist shaped by the unprecedented moral dilemmas those developments in turn created.

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.

In 1974 India joined the elite roster of nuclear world powers when it exploded its first nuclear bomb. But the technological progress that facilitated that feat was set in motion many decades before, as India sought both independence from the British and respect from the larger world. Over the course of the twentieth century, India metamorphosed from a marginal place to a serious hub of technological and scientific innovation. It is this tale of transformation that Robert S. Anderson recounts in Nucleus and Nation.

Tracing the long institutional and individual preparations for India’s first nuclear test and its consequences, Anderson begins with the careers of India’s renowned scientists—Meghnad Saha, Shanti Bhatnagar, Homi Bhabha, and their patron Jawaharlal Nehru—in the first half of the twentieth century before focusing on the evolution of the large and complex scientific community—especially Vikram Sarabhi—in the later part of the era. By contextualizing Indian debates over nuclear power within the larger conversation about modernization and industrialization, Anderson hones in on the thorny issue of the integration of science into the framework and self-reliant ideals of Indian nationalism. In this way, Nucleus and Nation is more than a history of nuclear science and engineering and the Indian Atomic Energy Commission; it is a unique perspective on the history of Indian nationhood and the politics of its scientific community.

The award-winning former editor of Science News shows that one of the most fascinating and controversial ideas in contemporary cosmology—the existence of multiple parallel universes—has a long and divisive history that continues to this day.

We often consider the universe to encompass everything that exists, but some scientists have come to believe that the vast, expanding universe we inhabit may be just one of many. The totality of those parallel universes, still for some the stuff of science fiction, has come to be known as the multiverse.

The concept of the multiverse, exotic as it may be, isn’t actually new. In The Number of the Heavens, veteran science journalist Tom Siegfried traces the history of this controversial idea from antiquity to the present. Ancient Greek philosophers first raised the possibility of multiple universes, but Aristotle insisted on one and only one cosmos. Then in 1277 the bishop of Paris declared it heresy to teach that God could not create as many universes as he pleased, unleashing fervent philosophical debate about whether there might exist a “plurality of worlds.”

As the Middle Ages gave way to the Renaissance, the philosophical debates became more scientific. René Descartes declared “the number of the heavens” to be indefinitely large, and as notions of the known universe expanded from our solar system to our galaxy, the debate about its multiplicity was repeatedly recast. In the 1980s, new theories about the big bang reignited interest in the multiverse. Today the controversy continues, as cosmologists and physicists explore the possibility of many big bangs, extra dimensions of space, and a set of branching, parallel universes. This engrossing story offers deep lessons about the nature of science and the quest to understand the universe.
