This book addresses a fascinating set of questions in theoretical physics which will both entertain and enlighten all students, teachers and researchers and other physics aficionados. These range from Newtonian mechanics to quantum field theory and cover several puzzling issues that do not appear in standard textbooks. Some topics cover conceptual conundrums, the solutions to which lead to surprising insights; some correct popular misconceptions in the textbook discussion of certain topics; others illustrate deep connections between apparently unconnected domains of theoretical physics; and a few provide remarkably simple derivations of results which are not often appreciated. The connoisseur of theoretical physics will enjoy a feast of pleasant surprises skilfully prepared by an internationally acclaimed theoretical physicist. Each topic is introduced with proper background discussion and special effort is taken to make the discussion self-contained, clear and comprehensible to anyone with an undergraduate education in physics.

This books aims at giving an overview over theoretical and phenomenological aspects of particle astrophysics and particle cosmology. To be of interest for both students and researchers in neighboring fields of physics, it keeps a balance between well established foundations that will not significantly change in the future and a more in-depth treatment of selected subfields in which significant new developments have been taking place recently. These include high energy particle astrophysics, such as cosmic high energy neutrinos, the interplay between detection techniques of dark matter in the laboratory and in high energy cosmic radiation, axion-like particles, and relics of the early Universe such as primordial magnetic fields and gravitational waves. It also contains exercises and thus will be suitable for both introductory and advanced courses in astroparticle physics.

This book provides a compilation of in-depth articles and reviews on key topics within gravitation, cosmology and related issues. It is a celebratory volume dedicated to Prof. Thanu Padmanabhan ("Paddy"), the renowned relativist and cosmologist from IUCAA, India, on the occasion of his 60th birthday. The authors, many of them leaders of their fields, are all colleagues, collaborators and former students of Paddy, who have worked with him over a research career spanning more than four decades. Paddy is a scientist of diverse interests, who attaches great importance to teaching. With this in mind, the aim of this compilation is to provide an accessible pedagogic introduction to, and overview of, various important topics in cosmology, gravitation and astrophysics. As such it will be an invaluable resource for scientists, graduate students and also advanced undergraduates seeking to broaden their horizons.

Planning to study science but feeling unsure about it ? We've got the perfect book for you! If you want to be an innovator , you must read about great scientists from around the world and get inspired by their work! Scientists are one of the main reasons that society has evolved to its current state. The efforts of some great scientists have contributed to the modernization of the world. Famous scientists like Isaac Newton and Galileo Galilei set an example for modern scientists. But there's a lot we don't know about it , and we're about to know all about it. So if you too are a science lover and dream of changing the world with your inventions , then read on and start creating! Scientists around the world have contributed to the development of medicine , physics , chemistry, and technology, among other important aspects of society. As a budding scientist , you can either adopt a theoretical approach or a practical approach. Both these methods are equally important in this field. In addition , research and development is necessary in all fields of scientific study , even for industrial purposes . So we understand the importance of scientists , let's take a look at some of the most brilliant minds and their contributions! Finally , you can even leave a comment to let us know how many of them you already know! Scientists of all fields are very important for the progress of the society. Some have completely changed the way the scientific community views science. So let's look at the world's famous greatest scientists.

The subject of the book is a biography of the theoretical physicist Arnold Sommerfeld (1868-1951). Although Sommerfeld is famous as a quantum theorist for the elaboration of the semi-classical atomic theory (Bohr-Sommerfeld model, Sommerfeld's fine-structure constant), his role in the history of modern physics is not confined to atoms and quanta. Sommerfeld left his mark in the history of mathematics, fluid mechanics, a number of physical subdisciplines and, in particular, as founder of a most productive "school" (Peter Debye, Wolfgang Pauli, Werner Heisenberg, Linus Pauling and Hans Bethe were his pupils, to name only the Nobel laureates among them). This biography is to a large extent based on primary source material (correspondence, diaries, unpublished manuscripts). It should be of particular interest to students who are keen to know more about the historical roots of modern science. Sommerfeld lived through turbulent times of German history (Wilhelmian Empire, Weimar Republic, Nazi period). His life, therefore, illustrates how science and scientists perform in changing social environments. From this perspective, the biography should also attract readers with a general interest in the history of science and technology.

The book ‘Science: From Peanut to Pinnacle’ is written in special interest of researchers and scientists of the world. It covers classical, traditional, as well as promising topics like historical background of science from early history to 21st century. It also reflects various types of branches of science, evolution of science, scientific research, scientific community, science and society, philosophy of science, etc. The book highlights the post-scientific revolution of science, politicization of science, antiscience, metascience, discoveries and inventions, psychology and sociology of science, scientific methods, scientometrics and so on. The topics like science communication, scientific literature, science journalism, and scientific revolution are especially written for budding researchers and project fellows, who are pursuing their masters or doctorates in the field of scientific research. The author acknowledges his colleagues and contemporaries for their valuable suggestions, timely feedbacks, and significant opinions. This book will definitely be a 24x7 guide and a handy tool for all researchers worldwide. The author feels highly indebted to ‘The Almighty Living God (The Supernatural Energy of The Third World)’, who has helped him directly or indirectly in writing this book. May all scientists of the world gain the abyssal knowledge in all the frontiers of science !

This book traces the history of Arnold Sommerfeld’s famous “nursery of theoretical physics” at the University of Munich and demonstrates the centrality of developing personal and institutional networks for the emergence of quantum theory. Sommerfeld, originally a mathematician with little interest in theoretical physics, was a somewhat unlikely choice for a chair of theoretical physics when he was appointed in 1906. However, he quickly reoriented his research focus towards physics, forstering a keen interest in experimental research. Possibly even more important for the development of quantum theory in the coming years was his exceptional talent as a charismatic teacher and prolific networker, which turned Munich into a central node in the fast-growing network of quantum physicists in the 1920s. It is no coincidence that the two most talented “child prodigies” of 1920s quantum physics, Wolfgang Pauli and Werner Heisenberg, were his students, nor that by the end of the decade about a dozen of Sommerfeld’s former disciples held chairs in theoretical physics. The book is directed at historians of science and physics, as well as all those interested in the history of science diplomacy and networking. The book is part of a series of publications on the early network of quantum physics. These works emerged from an expansive study on the quantum revolution as a major transformation of physical knowledge undertaken by the Max Planck Institute for the History of Science and the Fritz Haber Institute (2006–2012).
