The focus of Unique Physics of Light and Astronomy, a brand new title from Professor Kadakia, is on the processes responsible for the creation of light and its interaction with matter. After several years of extensive research in light wave physics, the author realized that several past physicists had left unexplained gaps in their theories characterizing the behavior of radiation entities in general, and light waves in particular. Though Einstein had postulated a dual nature of of light and radiation, namely a particle and a wave, which travelled at a constant speed c in space, he did not describe the physical phenomenon for the origination of radiant energy. In this text book, we reveal the unique events surrounding the creation of light and radiation waves. They are germinated from a quantum phenomenon, electrons dissipate energy during orbital transitions, inherently due to a quantized change in their energy states while performing oscillations within electrostatic charge field of protons. Thus, the frequencies and the speed of all radiation is set by the reverberation of the charge field that is independent of the motion of atoms and objects. Moreover, various types of radiation is thus considered as manifestations of oscillations of the charge field at different frequencies and, therefore, are not electromagnetic in nature. The readers of this text will be amazed by the several stunning breakthrough ideas presented here. For instance, we developed a novel concept for the probability of finding a radiation quantum in Richard Feynman's QED that is determined from the wave function of a particle electron that creates the radiation. Another remarkable fact that is postulated by us is that "Black Holes" do not possess a singularity, as was made popular by Stephen Hawking, inasmuch as they are quark stars in reality. Finally, we proudly announce that we have revised the most celebrated mass-energy equivalence expression, as postulated by Albert Einstein, for translation of matter into energy E = mc2 to new a relationship to wit: E = Ʃmneutrinoc2 + Ʃhfradiation.

This book is the first of its kind to devote itself at this level to the key role played by light and electromagnetic radiation in the universe. Readers are introduced to philosophical hypotheses such as the economy, symmetry, and universality of natural laws, and are then guided to practical consequences such as the rules of geometrical optics and even Einstein's well-known but mysterious relationship, E = mc2. Most chapters feature a pen picture of the life and character of a relevant scientific figure. These “Historical Interludes” include, among others, Galileo's conflicts with the Inquisition, Fourier's taunting of the guillotine, Neils Bohr and World War II, and the unique character of Richard Feynman. Going one step beyond the popular level, this easy-to-read book gives an overall view to undergraduate and postgraduate physics students that is often missing when trying to assimilate the technical details of their courses. Through its original treatment of topics and enjoyable style of writing, it will also stimulate keen interest in general readers who are interested in science and have a basic mathematics background as well as teachers looking for basic and accurate background information.Contents: Light, the Central Actor; Geometrical Optics — Reflection; Geometrical Optics — Refraction; Light from Afar — Astronomy; Light from the Past — Astrophysics; Introducing Waves; Sound Waves; Light as a Wave; Making Images; There Was Electricity, and Then There Was Light; 'Atoms of Light' — The Birth of Quantum Theory; The Development of Quantum Mechanics; Atoms of Light Acting as Particles; Atoms of Light Behaving as Waves; Special Relativity — How It Began; Special Relativity — Verifiable Predictions; Epilogue.

This textbook provides an introduction to gravitational lensing, which has become an invaluable tool in modern astrophysics, with applications that range from finding planets orbiting distant stars to understanding how dark matter and dark energy conspired to form the cosmic structures we see today. Principles of Gravitational Lensing begins with Einstein’s prediction that gravity bends light, and shows how that fundamental idea has spawned a rich field of study over the past century. The gravitational deflection of light was first detected by Eddington during a solar eclipse in May 1919, launching Einstein and his theory of relativity into public view. Yet the possibility of using the phenomenon to unlock mysteries of the Universe seemed remote, given the technology of the day. Theoretical work was carried out sporadically over the next six decades, but only with the discovery of the system Q0957+561 in 1979 was gravitational lensing transformed from a curiosity of general relativity into a practical observational tool. This book describes how the three subfields known as strong lensing, weak lensing, and microlensing have grown independently but become increasingly intertwined. Drawing on their research experience, Congdon and Keeton begin with the basic physics of light bending, then present the mathematical foundations of gravitational lensing, building up to current research topics in a clear and systematic way. Relevant background material from physics and mathematics is included, making the book self-contained. The derivations and explanations are supplemented by exercises designed to help students master the theoretical concepts as well as the methods that drive current research. An extensive bibliography guides those wishing to delve more deeply into particular areas of interest. Principles of Gravitational Lensing is ideal for advanced students and seasoned researchers looking to penetrate this thriving subject and even contribute research of their own.

Light and light based technologies have played an important role in transforming our lives via scientific contributions spanned over thousands of years. In this book we present a vast collection of articles on various aspects of light and its applications in the contemporary world at a popular or semi-popular level. These articles are written by the world authorities in their respective fields. This is therefore a rare volume where the world experts have come together to present the developments in this most important field of science in an almost pedagogical manner. This volume covers five aspects related to light. The first presents two articles, one on the history of the nature of light, and the other on the scientific achievements of Ibn-Haitham (Alhazen), who is broadly considered the father of modern optics. These are then followed by an article on ultrafast phenomena and the invisible world. The third part includes papers on specific sources of light, the discoveries of which have revolutionized optical technologies in our lifetime. They discuss the nature and the characteristics of lasers, Solid-state lighting based on the Light Emitting Diode (LED) technology, and finally modern electron optics and its relationship to the Muslim golden age in science. The book’s fourth part discusses various applications of optics and light in today's world, including biophotonics, art, optical communication, nanotechnology, the eye as an optical instrument, remote sensing, and optics in medicine. In turn, the last part focuses on quantum optics, a modern field that grew out of the interaction of light and matter. Topics addressed include atom optics, slow, stored and stationary light, optical tests of the foundation of physics, quantum mechanical properties of light fields carrying orbital angular momentum, quantum communication, and Wave-Particle dualism in action.

From the big bang to black holes, this fast-paced illustrated tour of time and space for the astro-curious unlocks the science of the stars to reveal fascinating theories, surprising discoveries, and ongoing mysteries in modern astronomy and astrophysics. Before the big bang, time, space, and matter didn't exist. In the 14 billion years since, scientists have pointed their telescopes upward, peering outward in space and backward in time, developing and refining theories to explain the weird and wonderful phenomena they observed. Through these observations, we now understand concepts like the size of the universe (still expanding), the distance to the next-nearest star from earth (Alpha Centauri, 26 trillion miles) and what drives the formation of elements (nuclear fusion), planets and galaxies (gravity), and black holes (gravitational collapse). But are these cosmological questions definitively answered or is there more to discover? Oxford University astrophysicist and popular YouTube personality Dr. Becky Smethurst presents everything you need to know about the universe in ten accessible and engagingly illustrated lessons. In Space at the Speed of Light: The History of 14 Billion Years for People Short on Time, she guides you through fundamental questions, both answered and unanswered, posed by space scientists. Why does gravity matter? How do we know the big bang happened? What is dark matter? Do aliens exist? Why is the sky dark at night? If you have ever looked up at night and wondered how it all works, you will find answers--and many more questions--in this pocket-sized tour of the universe!

Light and Life in the Universe: Selected Lectures in Physics, Biology and the Origin of Life is a collection of lectures given at the 1964 Nuclear Research Foundation Summer Science School for High School Students, held at the University of Sydney, Australia, on January 6-17, 1964. The papers explore various aspects of life, both on earth and in the universe generally. Emphasis is placed on the ""units"" of living matter, how life may have started on earth, and the possibility of life on other planets. This book is comprised of 15 chapters and begins with a brief description of some of the properties of atoms and how they join up to form molecules, as well as some of the properties of the central core of each atom. The discussion then turns to electromagnetic radiation, highlighting the difficulties originally encountered by Ernest Rutherford's picture of the atom. Subsequent chapters focus on the influence of gravitational fields; the origin of the solar system; the evolution of life on earth; and link between the primordial atmosphere and the origin of life. The functions of proteins, the practical effects of biology on humans, and the replication of living molecules are also considered. This monograph is written specifically for fourth-year high school students interested in astronomy, physics, chemistry, and biology.
