Atomic-Scale Electronics Beyond CMOS
by Mircea Dragoman Daniela DragomanThis book explores emerging topics in atomic- and nano-scale electronics after the era of Moore’s Law, covering both the physical principles behind, and technological implementations for many devices that are now expected to become key elements of the future of nanoelectronics beyond traditional complementary metal-oxide semiconductors (CMOS). Moore’s law is not a physical law itself, but rather a visionary prediction that has worked well for more than 50 years but is rapidly coming to its end as the gate length of CMOS transistors approaches the length-scale of only a few atoms. Thus, the key question here is: “What is the future for nanoelectronics beyond CMOS?” The possible answers are found in this book. Introducing novel quantum devices such as atomic–scale electronic devices, ballistic devices, memristors, superconducting devices, this book also presents the reader with the physical principles underlying new ways of computing, as well as their practical implementation. Topics such as quantum computing, neuromorphic computing are highlighted here as some of the most promising candidates for ushering in a new era of atomic-scale electronics beyond CMOS.
Atomic-Scale Insights into Emergent Photovoltaic Absorbers (Springer Theses)
by Alex GanoseThis book presents an original investigation into alternative photovoltaic absorbers. Solar power is a highly promising renewable energy solution; however, its success is hampered by the limited cost-effectiveness of current devices. The book assesses the photovoltaic performance of over 20 materials using state-of-the-art, first-principles methods. Adopting a computational approach, it investigates atomic-scale properties at a level of accuracy that is difficult to achieve using laboratory-based experimental techniques. Unlike many theoretical studies, it provides specific advice to those involved in experimental investigations. Further, it proposes directions for future research. This book advances the field of photovoltaics in three crucial ways: firstly, it identifies why one class of proposed materials cannot achieve high efficiency, while at the same time gaining insights that can be used to design future absorbers. Secondly, it shows that poor performance in the bismuth chalcohalides is not due to fundamental limitations, and can be overcome by finely controlling synthesis conditions. Lastly, it describes a range of new stable materials that are expected to show excellent photovoltaic performance.

Atoms Under the Floorboards: The Surprising Science Hidden in Your Home
by Chris Woodford<p>Using the modern home as a springboard, Atoms Under the Floorboards presents the fascinating and surprising scientific explanations behind a variety of common (and often entertainingly mundane) household phenomena, from gurgling drains and squeaky floorboards to rubbery custard and shiny shoes. <p>Packed with facts and fun, each chapter focuses on the objects and processes familiar in everyday life and slowly unpicks the science behind them. For example, the chapter on how buildings work introduces static and dynamic forces in explaining why buildings (and their foundations) don't sink into the ground and why skyscrapers don't blow over in strong winds. The chapter on bicycles explores how "circles (better known as wheels) with a few flimsy bits of metal (spokes) stretched between them" are able to support your weight--and this leads into a discussion of compression, tension, and how gears work. <p>After reading Atoms Under the Floorboards, you'll never look at everyday objects the same way again.</p>
Atoms and Eden: Conversations on Religion and Science
by Steve PaulsonHere is an unprecedented collection of twenty freewheeling and revealing interviews with major players in the ongoing--and increasingly heated--debate about the relationship between religion and science. These lively conversations cover the most important and interesting topics imaginable: the Big Bang, the origins of life, the nature of consciousness, the foundations of religion, the meaning of God, and much more. In Atoms and Eden, Peabody Award-winning journalist Steve Paulson explores these topics with some of the most prominent public intellectuals of our time, including Richard Dawkins, Karen Armstrong, E. O. Wilson, Sam Harris, Elaine Pagels, Francis Collins, Daniel Dennett, Jane Goodall, Paul Davies, and Steven Weinberg. The interviewees include Christians, Buddhists, Jews, and Muslims, as well as agnostics, atheists, and other scholars who hold perspectives that are hard to categorize. Paulson's interviews sweep across a broad range of scientific disciplines--evolutionary biology, quantum physics, cosmology, and neuroscience--and also explore key issues in theology, religious history, and what William James called ''the varieties of religious experience. '' Collectively, these engaging dialogues cover the major issues that have often pitted science against religion--from the origins of the universe to debates about God, Darwin, the nature of reality, and the limits of human reason. These are complex, intellectually rich discussions, presented in an accessible and engaging manner. Most of these interviews were originally published as individual cover stories for Salon. com, where they generated a huge reader response. Public Radio's "To the Best of Our Knowledge" will present a major companion series on related topics this fall. A feast of ideas and competing perspectives, this volume will appeal to scientists, spiritual seekers, and the intellectually curious.

Atoms and Molecules: Investigating the Building Blocks of Matter (Scientific Pathways)
by Chris Woodford Martin Clowes<p>Greek philosophers first hypothesized that matter was composed of atoms, but the theory would not resurface again until the late 17th century. The idea that that atoms joined to form structures called molecules first appeared in the 19th century and helped explain why gases, liquids, and solids behave differently from one another. In the 20th century subatomic particles were discovered-electrons, protons, and neutrons-and atomic structure was finally understood. These breakthroughs led to the development of quantum theory and quantum mechanics. <p>This book details the inspiring and heroic discovery, delving deeply into intriguing stories, reviewing major scientific landmarks, and introducing readers to the vivid men and women who helped discover and map the microscopic universe that is the atom. Supplemental content includes an activity spread, a substantial and highly detailed timeline, and a list of key people with mini-biographies.</p>
Atoms in the Family: My Life with Enrico Fermi
by Laura FermiIn this absorbing account of life with the great atomic scientist Enrico Fermi, Laura Fermi tells the story of their emigration to the United States in the 1930s—part of the widespread movement of scientists from Europe to the New World that was so important to the development of the first atomic bomb. Combining intellectual biography and social history, Laura Fermi traces her husband's career from his childhood, when he taught himself physics, through his rise in the Italian university system concurrent with the rise of fascism, to his receipt of the Nobel Prize, which offered a perfect opportunity to flee the country without arousing official suspicion, and his odyssey to the United States.

Atoms of Mind: The "Ghost in the Machine" Materializes
by W. R. KlemmThis book describes the author's view of how the mind "thinks" at various levels of operation. These levels include nonconscious mind (as in spinal/brainstem reflexes and neuroendocrine controls), subconscious mind, and conscious mind. In the attempt to explain conscious mind, there is considerable critique of arguments over whether or not free will is an illusion. Finally, the author summarizes current leading theories for consciousness (Bayesian probability, chaos, and quantum mechanics) and then presents his own theory based on patterns of nerve impulses in circuits that are interlaced coherently into larger networks.
Atoms, Bytes and Genes: Public Resistance and Techno-Scientific Responses (Routledge Advances in Sociology #126)
by Martin W. Bauer"Atom," "byte" and "gene" are metonymies for techno-scientific developments of the 20th century: nuclear power, computing and genetic engineering. Resistance continues to challenge these developments in public opinion. This book traces historical debates over atoms, bytes and genes which raised controversy with consequences, and argues that public opinion is a factor of the development of modern techno-science. The level and scope of public controversy is an index of resistance, examined here with a "pain analogy" which shows that just as pain impacts movement, resistance impacts techno-scientific mobilization: it signals that something is wrong, and this requires attention, elaboration and a response to the challenge. This analysis shows how different fields of enquiry deal with the resistance of social-psychological mentalities in the face of industrial, scientific and political activities inspired by projected futures.
