Mathematics for Natural Scientists II: Advanced Methods (Undergraduate Lecture Notes in Physics)
By Lev Kantorovich. 2024
This textbook, the second in a series (the first covered fundamentals and basics), seeks to make its material accessible to…
physics students. Physics/engineering can be greatly enhanced by knowledge of advanced mathematical techniques, but the math-specific jargon and laborious proofs can be off-putting to students not well versed in abstract math. This book uses examples and proofs designed to be clear and convincing from the context of physics, as well as providing a large number of both solved and unsolved problems in each chapter. This is the second edition, and it has been significantly revised and enlarged, with Chapters 1 (on linear algebra) and 2 (on the calculus of complex numbers and functions) having been particularly expanded. The enhanced topics throughout the book include: vector spaces, general (non-Hermitian, including normal and defective) matrices and their right/left eigenvectors/values, Jordan form, pseudoinverse, linearsystems of differential equations, Gaussian elimination, fundamental theorem of algebra, convergence of a Fourie series and Gibbs-Wilbraham phenomenon, careful derivation of the Fourier integral and of the inverse Laplace transform. New material has been added on many physics topics meant to illustrate the maths, such as 3D rotation, properties of the free electron gas, van Hove singularities, and methods for both solving PDEs with a Fourier transform and calculating the width of a domain wall in a ferromagnet, to mention just a few. This textbook should prove invaluable to all of those with an interest in physics/engineering who have previously experienced difficulty processing the math involved.Quantum Mechanics (The Ladybird Expert Series #2)

By Kitty Ferguson. 1973
What is a black hole? Could we survive a visit to one? Perhaps even venture inside? What would we find?…
Have we yet discovered any real black holes? And what do black holes teach us about what physicist John Archibald Wheeler called “the deep, happy, mysteries of the universe”?These are just a few of the tantalizing questions examined in this jargon-free review of one of the most fascinating topics in modern science. In search of the answers, we trace a star from its birth to its death throes, take a fabulous hypothetical journey to the border of a black hole and beyond, spend time with some of the world’s leading theoretical physicists and observational astronomers scanning the cosmos for evidence of real black holes, and take a whimsical look at some of the wild ideas black holes have inspired.Positively Happy: Cosmic Ways To Change Your Life

be human and what technology can really achieve' Sunday Telegraph'Peter's story is one of the most extraordinary you will ever hear. I urge people to read it' Stephen Fry'A remarkable story . . . you're left desperate to take nothing for granted' Radio Times __________ Peter, a brilliant scientist, is told that he will lose everything he loves. His husband. His family. His friends. His ability to travel the world. All will be gone. But Peter will not give up. He vows that this will not be the end and instead seeks a completely new beginning . . . Peter has Motor Neurone Disease, a condition universally considered by doctors to be terminal. He is told it will destroy his nerve cells and that within about two years, it will take his life too. But, face-to-face with death, he decides there is another way. Using his background in science and technology, he navigates a new path, one that will enable him not just to survive, but to thrive. This is the astonishing true story about Peter Scott-Morgan: the first person to combine his very humanity with artificial intelligence and robotics to become a full Cyborg. His discovery means that his terminal diagnosis is negotiable, something that will rewrite the future.And change the world. By embracing love, life and hope rather than fear, tragedy and despair, he will become Peter 2.0. __________'Compelling . . . Scott-Morgan is a true one-off. It is in the telling of the love story, rather than the technical details of becoming a cyborg, that this book succeeds' The Times 'What's striking is Peter's constant optimism, bravery and his ability to find radical answers to problems that have confounded Britain's brightest minds' Daily Telegraph 'A soaring love story' Financial Times 'Fascinating and extremely moving' SunPagan Paths: A Guide to Wicca, Druidry, Asatru Shamanism and Other Pagan Practices

By Jie Zheng Matthew C. Trudeau. 2023
The Textbook of Ion Channels is a set of three volumes providing a wide-ranging reference source on ion channels for…
students, instructors and researchers. Ion channels are membrane proteins that control the electrical properties of neurons and cardiac cells; mediate the detection and response to sensory stimuli like light, sound, odor, and taste; and regulate the response to physical stimuli like temperature and pressure. In non-excitable tissues, ion channels are instrumental for the regulation of basic salt balance that is critical for homeostasis. Ion channels are located at the surface membrane of cells, giving them the unique ability to communicate with the environment, as well as the membrane of intracellular organelles, allowing them to regulate internal homeostasis. Ion channels are fundamentally important for human health and diseases, and are important targets for pharmaceuticals in mental illness, heart disease, anesthesia, pain and other clinical applications. The modern methods used in their study are powerful and diverse, ranging from single ion-channel measurement techniques to models of ion channel diseases in animals, and human clinical trials for ion channel drugs.Volume I, Part 1 covers fundamental topics such as the basic principles of ion permeation and selectivity, voltage-dependent, ligand-dependent, and mechano-dependent ion channel activation mechanisms, the mechanisms for ion channel desensitization and inactivation, and basic ion channel pharmacology and inhibition. Volume I, Part 2 offers a practical guide of cardinal methods for researching ion channels, including heterologous expression and voltage-clamp and patch-clamp electrophysiology; isolation of native currents using patch clamping; modeling ion channel gating, structures, and its dynamics; crystallography and cryo-electron microscopy; fluorescence and paramagnetic resonance spectroscopy methods; and genetics approaches in model organisms.All three volumes give the reader an introduction to fundamental concepts needed to understand the mechanism of ion channels; a guide to the technical aspects of ion channel research; a modern guide to the properties of major ion channel families; and includes coverage of key examples of regulatory, physiological and disease roles for ion channels.Boltzmann's Atom: The Great Debate That Launched a Revolution in Physics
By David Lindley. 2001
In 1900 many eminent scientists did not believe atoms existed, yet within just a few years the atomic century launched…
into history with an astonishing string of breakthroughs in physics that began with Albert Einstein and continues to this day. Before this explosive growth into the modern age took place, an all-but-forgotten genius strove for forty years to win acceptance for the atomic theory of matter and an altogether new way of doing physics. Ludwig Boltz-mann battled with philosophers, the scientific establishment, and his own potent demons. His victory led the way to the greatest scientific achievements of the twentieth century.Now acclaimed science writer David Lindley portrays the dramatic story of Boltzmann and his embrace of the atom, while providing a window on the civilized world that gave birth to our scientific era. Boltzmann emerges as an endearingly quixotic character, passionately inspired by Beethoven, who muddled through the practical matters of life in a European gilded age.Boltzmann's story reaches from fin de siècle Vienna, across Germany and Britain, to America. As the Habsburg Empire was crumbling, Germany's intellectual might was growing; Edinburgh in Scotland was one of the most intellectually fertile places on earth; and, in America, brilliant independent minds were beginning to draw on the best ideas of the bureaucratized old world.Boltzmann's nemesis in the field of theoretical physics at home in Austria was Ernst Mach, noted today in the term Mach I, the speed of sound. Mach believed physics should address only that which could be directly observed. How could we know that frisky atoms jiggling about corresponded to heat if we couldn't see them? Why should we bother with theories that only told us what would probably happen, rather than making an absolute prediction? Mach and Boltzmann both believed in the power of science, but their approaches to physics could not have been more opposed. Boltzmann sought to explain the real world, and cast aside any philosophical criteria. Mach, along with many nineteenth-century scientists, wanted to construct an empirical edifice of absolute truths that obeyed strict philosophical rules. Boltzmann did not get on well with authority in any form, and he did his best work at arm's length from it. When at the end of his career he engaged with the philosophical authorities in the Viennese academy, the results were personally disastrous and tragic. Yet Boltzmann's enduring legacy lives on in the new physics and technology of our wired world.Lindley's elegant telling of this tale combines the detailed breadth of the best history, the beauty of theoretical physics, and the psychological insight belonging to the finest of novels.Dieses Buch macht die überraschende Vielfalt der Personen und Tätigkeiten in der Radioaktivitätsforschung sichtbar. Dabei wird der Begriff der wissenschaftlichen…
Arbeit neu konzeptualisiert. Neben die Forschungsarbeit im Labor treten scheinbare Rand-, Neben- und Routinetätigkeiten, die für die Radioaktivitätsforschung als Disziplin von zentraler Bedeutung waren.Badeärzte, Industriechemiker und Bergbaubeamte waren an der Erforschung der neuen Substanzen und Strahlen ebenso beteiligt wie eine vergleichsweise hohe Zahl von Frauen. Die erste umfassende Studie zur deutschsprachigen Radioaktivitätsforschung im vorderen Teil des Buches offenbart die Ausnahmestellung der Hauptstädte Berlin und Wien für die Forschung ebenso wie fruchtbares akademisches Leben in der Provinz; sie zeigt, wie das neue Gebiet an den Hochschulen in die Lehre einzog und welchen Beitrag Professoren, Privatdozenten und Promovierende zur Forschung leisteten. Erstmals wird auch die Bedeutung der Wasseruntersuchungen aufgezeigt, die durch die Hoffnung auf radioaktive Heilquellen angetrieben wurden.Im zweiten Teil werden in internationaler Perspektive unsichtbare und in der Geschichtsschreibung oft wenig beachtete Facetten der „Arbeit mit dem Radium“ untersucht. So mussten Instrumente und radioaktive Präparate überhaupt erst hergestellt und in Umlauf gebracht werden. Auch die Etablierung von Nachweismethoden für Radioaktivität erforderte viel Arbeit, von der niemand sprach. Dienstleistungen wie die Entwicklung therapeutisch nutzbarer Präparate, Gutachtertätigkeiten, die Herausgabe einer Zeitschrift oder die Organisation eines Kongresses werden als integraler Bestandteil der wissenschaftlichen Arbeit in ihrer Bedeutung dargestellt. Eine Reflexion zur Arbeitsorganisation und zum disziplinären Status bündelt die Ergebnisse in einer neuen Gesamtsicht auf die frühe Radioaktivitätsforschung.Computational Methods and Mathematical Modeling in Cyberphysics and Engineering Applications 1
By Dmitri Koroliouk, Sergiy Lyashko, Nikolaos Limnios. 2024
Mathematical methods in engineering are characterized by a wide range of techniques for approaching various problems. Moreover, completely different analysis…
techniques can be applied to the same problem, which is justified by the difference in specific applications. Therefore, the study of the analyses and solutions of specific problems leads the researcher to generate their own techniques for the analysis of similar problems continuously arising in the process of technical development. Computational Methods and Mathematical Modeling in Cyberphysics and Engineering Applications contains solutions to specific problems in current areas of computational engineering and cyberphysics.Breaking the Time Barrier: The Race to Build the First Time Machine
By Jenny Randles. 2005
IT WAS ONLY A MATTER OF TIME.... Once widely considered an impossibility--the stuff of science fiction novels--time travel may finally…
be achieved in the twenty-first century. In Breaking the Time Barrier, bestselling author Jenny Randles reveals the nature of recent, breakthrough experiments that are turning this fantasy into reality. The race to build the first time machine is a fascinating saga that began about a century ago, when scientists such as Marconi and Edison and Einstein carried out research aimed at producing a working time machine. Today, physicists are conducting remarkable experiments that involve slowing the passage of information, freezing light, and breaking the speed of light--and thus the time barrier. In the 1960s we had the "space race." Today, there is a "time race" involving an underground community of working scientists who are increasingly convinced that a time machine of some sort is finally possible. Here, Randles explores the often riveting motives of the people involved in this quest (including a host of sincere, if sometimes misguided amateurs), the consequences for society should time travel become a part of everyday life, and what evidence might indicate that it has already become reality. For, if time travel is going to happen--and some Russian scientists already claim to have achieved it in a lab--then its effects may already be apparent.Physik für Dummies: Das Lehrbuch (Für Dummies)

By Rosaly M. C. Lopes, Katherine De Kleer, James Tuttle Keane. 2023
Written by expert researchers, this book covers all the major aspects of research in Jupiter's moon Io, from the interior…
to its space environment. Io is one of the Solar System’s most exotic satellites. The book discusses Io's interior, geology, atmosphere, and, in particular, its active volcanism, which was discovered from observations by the Voyager 1 spacecraft in 1979, confirming a possibility suggested from theoretical studies based on Io’s orbit. Our knowledge of Io’s volcanism, composition, and space environment was significantly increased as a result of observations by other spacecrafts, including Galileo.More than a decade after the 1st edition, “Io After Galileo”, this 2nd edition of the book now includes results obtained by the New Horizons mission and, more recently, Juno. It also presents observational results from ground-based telescopes using adaptive optics having provided resolutions that rival those of spacecraft.The book provides a review of the current status of Io research and gives an outlook to planned future observations. It thus serves as reference for researchers in the field and an introduction for PhD students and newcomers planning to study this exotic Solar System moon.The Everything Love Spells Book: Potions and Incantations to Spice Up Your Love Life (The Everything Books)

By Walter Lewin, Warren Goldstein. 2011
“YOU HAVE CHANGED MY LIFE” is a common refrain in the emails Walter Lewin receives daily from fans who have…
been enthralled by his world-famous video lectures about the wonders of physics. “I walk with a new spring in my step and I look at life through physics-colored eyes,” wrote one such fan. When Lewin’s lectures were made available online, he became an instant YouTube celebrity, and The New York Times declared, “Walter Lewin delivers his lectures with the panache of Julia Child bringing French cooking to amateurs and the zany theatricality of YouTube’s greatest hits.” For more than thirty years as a beloved professor at the Massachusetts Institute of Technology, Lewin honed his singular craft of making physics not only accessible but truly fun, whether putting his head in the path of a wrecking ball, supercharging himself with three hundred thousand volts of electricity, or demonstrating why the sky is blue and why clouds are white. Now, as Carl Sagan did for astronomy and Brian Green did for cosmology, Lewin takes readers on a marvelous journey in For the Love of Physics, opening our eyes as never before to the amazing beauty and power with which physics can reveal the hidden workings of the world all around us. “I introduce people to their own world,” writes Lewin, “the world they live in and are familiar with but don’t approach like a physicist—yet.” Could it be true that we are shorter standing up than lying down? Why can we snorkel no deeper than about one foot below the surface? Why are the colors of a rainbow always in the same order, and would it be possible to put our hand out and touch one? Whether introducing why the air smells so fresh after a lightning storm, why we briefly lose (and gain) weight when we ride in an elevator, or what the big bang would have sounded like had anyone existed to hear it, Lewin never ceases to surprise and delight with the extraordinary ability of physics to answer even the most elusive questions. Recounting his own exciting discoveries as a pioneer in the field of X-ray astronomy—arriving at MIT right at the start of an astonishing revolution in astronomy—he also brings to life the power of physics to reach into the vastness of space and unveil exotic uncharted territories, from the marvels of a supernova explosion in the Large Magellanic Cloud to the unseeable depths of black holes. “For me,” Lewin writes, “physics is a way of seeing—the spectacular and the mundane, the immense and the minute—as a beautiful, thrillingly interwoven whole.” His wonderfully inventive and vivid ways of introducing us to the revelations of physics impart to us a new appreciation of the remarkable beauty and intricate harmonies of the forces that govern our lives.Semiconductor Optics 2: Dynamics, High-Excitation Effects, and Basics of Applications (Graduate Texts in Physics)
By Heinz Kalt, Claus F. Klingshirn. 2024
This book provides an introduction to and an overview of the multifaceted area of dynamics and nonlinearities related to optical…
excitations in semiconductors. It is a revised and significantly extended edition of the well-established book by C. Klingshirn split into two volumes and restructured to make it more concise. Inserts on important experimental techniques, reference to topical research and novel materials, as well as consideration of photonic applications support research-oriented teaching and learning. This book reviews nonlinear optical properties and many-body phenomena evoked by high densities of quasi-particles in semiconductors. Coherent dynamics and relaxation of optical excitations (carriers, excitons, electron–hole plasmas, etc.) as well as condensation phenomena are elucidated in these materials. A broad overview is provided of seminal research results augmented by detailed descriptions of the relevant experimental techniques, e.g., ultrafastspectroscopy, four-wave mixing, and the Hanbury-Brown and Twiss experiment. Offering a comprehensive introduction to hot topics in current research — polariton condensates, valley coherence, and single photons, to name a few, it also discusses applications of the described physical concepts in topical areas, such as quantum information, photonics, spintronics, and optoelectronics.Covering subjects ranging from physics to materials science and optoelectronics, the book provides a lively and comprehensive introduction to semiconductor optics beyond the linear regime.With many problems, chapter introductions, schematic depictions of physical phenomena, as well as boxed inserts and a detailed index, it is suitable for use in graduate courses in physics and neighboring sciences like material science and optical communication. It is also a valuable reference resource for doctoral and advanced researchers.Second-Order Photogalvanic Photocurrents in 2D Materials (SpringerBriefs in Applied Sciences and Technology)
By Mustafa Eginligil, Ting Yu. 2024
This book highlights the photogalvanic effects at low dimensions, surfaces, and interfaces, more specifically 2D materials, such as graphene and…
monolayer transition metal dichalcogenides. Although the phenomenology of the photogalvanic effects, which can be simply seen as photoresponse nonlinear-in-electric field, have been well-established, the microscopic understanding in each material system may vary. This book is a quick reference and a detailed roadmap starting from phenomenology and continuing with the ultimate low dimensional materials, in which the photogalvanic effects can offer a rich platform at the second-order response to an electric field. A general phenomenology of photogalvanic effect is provided in the first chapter, together with the photon drag effect which also generates a photocurrent like the photogalvanic effect, but with some distinct features, as well as somewhat puzzling similarities. Next two chapters explain these effects in graphene, starting with a necessary related background on graphene, then a particular focus on its specific phenomenology, microscopic theory, and experimental results. In a similar fashion, in chapters four and five, a necessary background for the photogalvanic effects in monolayer transition metal dichalcogenides, with symmetry analysis, microscopic theory, and experimental results is presented, along with the Berry curvature dependent photocurrent, which can also play an important role in 2D semiconductors. The second-order photogalvanic effects that have been covered so far in graphene and monolayer transition metal chalcogenides have already excited the 2D semiconductor optoelectronic research community by several means. It seems that the interests on the photogalvanic effects will continue to escalate in near future.
