his work on nineteenth-century physics.In 1847, Herman Helmholtz, arguably the most important German physicist of the nineteenth century, published his formulation of what became known as the conservation of energy--unarguably the most important single development in physics of that century, transforming what had been a conglomeration of separate topics into a coherent field unified by the concept of energy. In Helmholtz and the Conservation of Energy, Kenneth Caneva offers a detailed account of Helmholtz's work on the subject, the sources that he drew upon, the varying responses to his work from scientists of the era, and the impact on physics as a discipline.Caneva describes the set of abiding concerns that prompted Helmholtz's work, including his rejection of the idea of a work-performing vital force, and investigates Helmholtz's relationship to both an older generation of physicists and an emerging community of reformist physiologists. He analyzes Helmholtz's indebtedness to Johannes Müller and Justus Liebig and discusses Helmholtz's tense and ambivalent relationship to the work of Robert Mayer, who had earlier proposed the uncreatability, indestructibility, and transformability of "force." Caneva examines Helmholtz's continued engagement with the subject, his role in the acceptance of the conservation of energy as the central principle of physics, and the eventual incorporation of the principle in textbooks as established science.By Carl S. Helrich. 2021
This book offers a fresh perspective on some of the central experimental and theoretical works that laid the foundations for…
today's quantum mechanics: It traces the theoretical and mathematical development of the hypotheses that put forward to explain puzzling experimental results; it also examines their interconnections and how they together evolved into modern quantum theory. Particular attention is paid to J.J. Thomson's atomic modeling and experiments at the Cavendish Laboratory, Max Planck's struggle to explain the experimental results of Heinrich Rubens and Ferdinand Kurlbaum, as well as the path leading from Louis de Broglie’s ideas to the wave theory of Erwin Schrödinger. Combining his experience in teaching quantum mechanics with his interest in the historical roots of the subject, the author has created a valuable resource for understanding quantum physics through its history, and a book that is appreciated both by working physicists and historians.By Vladimir G. Romanov, Alemdar Hasanov Hasanoğlu. 2021
This book presents a systematic exposition of the main ideas and methods in treating inverse problems for PDEs arising in…
basic mathematical models, though it makes no claim to being exhaustive. Mathematical models of most physical phenomena are governed by initial and boundary value problems for PDEs, and inverse problems governed by these equations arise naturally in nearly all branches of science and engineering.The book’s content, especially in the Introduction and Part I, is self-contained and is intended to also be accessible for beginning graduate students, whose mathematical background includes only basic courses in advanced calculus, PDEs and functional analysis. Further, the book can be used as the backbone for a lecture course on inverse and ill-posed problems for partial differential equations.In turn, the second part of the book consists of six nearly-independent chapters. The choice of these chapters was motivated by the fact that the inverse coefficient and source problems considered here are based on the basic and commonly used mathematical models governed by PDEs. These chapters describe not only these inverse problems, but also main inversion methods and techniques. Since the most distinctive features of any inverse problems related to PDEs are hidden in the properties of the corresponding solutions to direct problems, special attention is paid to the investigation of these properties.For the second edition, the authors have added two new chapters focusing on real-world applications of inverse problems arising in wave and vibration phenomena. They have also revised the whole text of the first edition.By Wolfgang Demtröder. 2021

MRI tissue diagnosis is the availability of relaxometric data and simple computer program proficiency. These programs are easy to use, highly interactive and the data processing is fast and unambiguous. Laboratories (with or without sophisticated facilities) can perform computational magnetic resonance diagnosis with only T1 and T2 relaxation data. The results have motivated the use of data to produce data-driven predictions required for machine learning, artificial intelligence (AI) and deep learning for multidisciplinary and interdisciplinary research. Consequently, this book is intended to be very useful for students, scientists, engineers, the medical personnel and researchers who are interested in developing new concepts for deeper appreciation of computational magnetic resonance imaging for medical diagnosis, prognosis, therapy and management of tissue diseases.By Kit Eaton. 2021

the universe through the author's favourite 100 stars.Astronomer Florian Freistetter has chosen 100 stars that have almost nothing in common. Some are bright and famous, some shine so feebly you need a huge telescope. There are big stars, small stars, nearby stars and faraway stars. Some died a while ago, others have not even yet come into being. Collectively they tell the story of the whole world, according to Freistetter. There is Algol, for example, the Demon Star, whose strange behaviour has long caused people sleepless nights. And Gamma Draconis, from which we know that the earth rotates around its own axis. There is also the star sequence 61 Cygni, which revealed the size of the cosmos to us.Then there are certain stars used by astronomers to search for extra-terrestrial life, to explore interstellar space travel, or to explain why the dinosaurs became extinct.In 100 short, fascinating and entertaining chapters, Freistetter not only reveals the past and future of the cosmos, but also the story of the people who have tried to understand the world in which we live.By Iflscience. 2020

FROM THE BESTSELLING AUTHOR OF REBECCAAn eloquent elegy on the past of a county she loved so much - The…
Times 'There was a smell in the air of tar and rope and rusted chain, a smell of tidal water. Down harbour, around the point, was the open sea. Here was the freedom I desired, long sought-for, not yet known. Freedom to write, to walk, to wander, freedom to climb hills, to pull a boat, to be alone . . . I for this, and this for me.'Daphne du Maurier lived in Cornwall for most of her life. Its rugged coastline, wild terrain and tumultuous weather inspired her imagination, and many of her works are set there, including Rebecca, Jamaica Inn and Frenchman's Creek.In Vanishing Cornwall she celebrates the land she loved, exploring its legends, its history and its people, eloquently making a powerful plea for Cornwall's preservation.By Professor Heino Falcke, Jörg Römer. 2021
As featured in THE EDGE OF ALL WE KNOW - the new Netflix documentary about Black HolesFor readers of Stephen…
Hawking, a fascinating account of the universe from the perspective of world-leading astrophysicist Heino Falcke, who took the first ever picture of a black hole.10th April 2019: a global sensation. Heino Falcke, a man "working at the boundaries of his discipline and therefore at the limits of the universe" had used a network of telescopes spanning the entire planet to take the first picture of a black hole.Light in the Darkness examines how mankind has always looked to the skies, mapping the journey from millennia ago when we turned our gaze to the heavens, to modern astrophysics. Heino Falcke and Jorg Romer entertainingly and compellingly chart the breakthrough research of Falcke's team, an unprecedented global community of international colleagues developing a telescope complex enough to look directly into a black hole - a hole where light vanishes, and time stops.What does this development mean? Is this the beginning of a new physics? What can we learn from this about God, the world, and ourselves? For Falcke, astrophysics and metaphysics, science and faith, do not exclude one another. Black Hole is both a plea for curiosity and humility; it's interested in both what we know, and the mysteries that remain unsolved.By Alexandre Zagoskin. 2003

give you everything you need to succeed, all in one place. It covers the key areas that students are expected to be confident in, outlining the basics in clear jargon-free English, and then providing added-value features like summaries of key ideas, and even lists of questions you might be asked in your exam. The book uses a structure that is designed to make quantum physics as accessible as possible - by starting with its similarities to Newtonian physics, rather than the rather startling differences.By Werner E G M ller, Xiaohong Wang, Heinz Schr der. 2013
