Waves in an Impossible Sea
Big Think's Best Science Book of 2024 A theoretical physicist takes readers on an awe-inspiring journey--found in "no other book" (Science)--to discover how the universe generates everything from nothing at all: "If you want to know what's really going on in the realms of relativity and particle physics, read this book" (Sean Carroll, author of The Biggest Ideas in the Universe). In Waves in an Impossible Sea, physicist Matt Strassler tells a startling tale of elementary particles, human experience, and empty space. He begins with a simple mystery of motion. When we drive at highway speeds with the windows down, the wind beats against our faces. Yet our planet hurtles through the cosmos at 150 miles per second, and we feel nothing of it. How can our voyage be so tranquil when, as Einstein discovered, matter warps space, and space deflects matter? The answer, Strassler reveals, is that empty space is a sea, albeit a paradoxically strange one. Much like water and air, it ripples in various ways, and we ourselves, made from its ripples, can move through space as effortlessly as waves crossing an ocean. Deftly weaving together daily experience and fundamental physics--the musical universe, the enigmatic quantum, cosmic fields, and the Higgs boson--Strassler shows us how all things, familiar and unfamiliar, emerge from what seems like nothing at all. Accessible and profound, Waves in an Impossible Sea is the ultimate guide to our place in the universe.

The Alethiology Proper
This Book is the first volume of the series "The Alethiology Proper". The Alethiology Proper is a new and independent discipline of Study (Science) which is a pure logical study of the nature of Reality and Truth. Etymologically "The Alethiology Proper" is defined as the "the Science of Truth Proper". In this study, Reality and Truth are taken as dual realities of the Same. Therefore, "The Alethiology Proper" can also be defined as "the Science of Reality Proper". This Study of Alethiology Proper has its unique methodology of study which has enabled to explore the ultimate answers of the Universe. Through this Study we can explore the Beginning and End of the Universe with absolute certainty. This Study has access even to Nothing and shows with absolute certainty what Nothing is and how Something came out of Nothing. Until now there were many unanswered questions about the Origin of Universe, Existence of God, Origin of Life etc. There are many conflicting theories, ideas, philosophies regarding the Truth of Everything due to the absence of Certainty of the Truth. This Study answers the questions of Origin of Universe, God, Life, Reality and Truth with absolute certainty. This study has bridged the two extremes (though in actuality are not) of Reality, namely Science and Religion, Physical and Spiritual, Seen and Unseen. Therefore, both realities can now be scientifically studied and confirmed with absolute certainty. This Study has independently explored the Reality and have come up with the answer that there is indeed God, a Triune Eternal Living Being. Before I say anything further, I would like to give assurance that this study is purely scientific which is purely objective in nature, therefore, all the ideas of this book could be experimentally verified with absolute certainty. This is not a mere philosophical book filled with subjective opinions or interpretations, but this is a purely objective and scientific study. If the ideas of this book are not equivalent in certainty as the Truth 2+2=4 is, then it may be considered as a fictional work.

Quantum Measurement
This book adopts a novel, physics-first approach to quantum measurement, using physical experiments as the basis to describe the underlying mathematical formalism. Topics covered include weak measurements, quantum measurement reversal, quantum trajectories and the stochastic path integral formalism. The theory of quantum measurement is also covered in detail, including discussion of how it can be tested and demonstrated in a laboratory: how to build quantum-limited amplifiers, fundamental noise limits imposed on measurement by quantum mechanics, and the design of superconducting circuits. This text is an excellent introduction for students with a basic understanding of quantum mechanics wanting to learn more about measurement theory, and the inclusion of a wide selection of end-of-chapter exercises make this book ideal for emerging courses on the topic. Key chapters introducing the foundations of quantum computing and the history of measurement theory are equally accessible to a broader, less specialised audience.
Interpreting Quantum Mechanics
This novel text directly addresses common claims and misconceptions around quantum mechanics and presents a fresh and modern understanding of this fundamental and essential physical theory. It begins with a non-mathematical introduction to some of the more controversial topics in the foundations of quantum mechanics. For those more familiar with the theoretical framework of quantum mechanics, the text moves on to a general introduction to quantum field theory, followed by a detailed discussion of cutting-edge topics in this area such as decoherence and spontaneous coherence. Several important philosophical problems in quantum mechanics are considered, and their interpretations are compared, notably the Copenhagen and many-worlds interpretations. The inclusion of frequent real-world examples, such as superconductors and superfluids, ensures the book remains grounded in modern research. This book will be a valuable resource for students and researchers in both physics and the philosophy of science interested in the foundations of quantum mechanics.
Light Quanta
Many may wonder about the title of this book. But one thing to note is that in 1951, Einstein told his friend Basso that, All these fifty years of conscious brooding have brought me no nearer to the answer to the question "What are light quanta?" Nowadays every Tom, Dick, and Harry thinks he knows it, but he is mistaken.This phrase has been mentioned by many people in their lectures, research papers and books. I think they know the exact meaning. Einstein doubted that there would be nothing like the postulated light quanta. But people are cheering for light quanta now. He was probably worried that something else would turn up later, showing that the light quanta were a trick used for the photoelectric effect. Because light is a wave and the energy in the wave cannot converge to a certain point, which he called light quanta. Secondly, he could not say what brings that energy together. What exactly that energy is, and why it depends on the frequency of the light wave, he could not tell. He was worried that it was just a trick used to solve the photoelectric effect.Read for where the classical theory went wrong in solving the photoelectric effect and how Einstein was wrong.Light is an electromagnetic wave. It contains asymmetric electric field which is responsible to produce the photoelectric effect. Any charged particle follows a curved path in asymmetric electric fields. Magnetic field is the effect of asymmetric electric field. Therefore, magnetic force increases with increase in frequency of the electromagnetic wave which is responsible to produce the photoelectric effect. Also, there is a phase difference of 90 degrees in electric field and magnetic field in electromagnetic. Both can be experimentally proved. See 'Photoelectric effect: the key point'.One can estimate total length of single light wave emitted by an atom using Air-wedge method. Sodium atom emits light wave having near abut 600 crests and troughs. So that electron producing it must vibrate 600 times at one place in the atom. So, if it is moving in orbit, how can produce such long light wave? See "The total length of single light wave emitted by sodium atom'.If you ask an uneducated person if all the electrons in an atom move around the nucleus, can a solid with constant shape be formed? So, he will say no but gas may be formed from such atoms. Electrons in an atom do not move in orbits. They can hold spin motion, which will cause to increase the magnetic repulsion between the paired electrons, and remain stationary. See 'Spin atomic model'.As the effect of asymmetric electric field is magnetic field, it is not as we understand magnetic field. A bar magnet has two electric field cones. Read 'What is Magnetic Field?'. This explains why magnetic monopoles are absent in the universe.Electric field in a light ray applies force on electric field of electron. Force is mutual. The electric field of the electron also exerts a force on the electric field of the light, causing the light beam to deviate. Read the 'Deflection of light rays in electric fields'.Relative speed of light and ether, particle and fields are discussed in different way.A must-read for science enthusiasts and those intrigued by the mysteries of the universe.
Back-of-the-Envelope Quantum Mechanics
Dimensional and order-of-magnitude estimates are practiced by almost everybody but taught almost nowhere. When physics students engage in their first theoretical research project, they soon learn that exactly solvable problems belong only to textbooks, that numerical models are long and resource consuming, and that 'something else' is needed to quickly gain insight into the system they are going to study. Qualitative methods are this 'something else', but typically, students have never heard of them before.The aim of this book is to teach the craft of qualitative analysis using a set of problems, some with solutions and some without, in advanced undergraduate and beginning graduate Quantum Mechanics. Examples include a dimensional analysis solution for the spectrum of a quartic oscillator, simple WKB formulas for the matrix elements of a coordinate in a gravitational well, and a three-line-long estimate for the ionization energy of atoms uniformly valid across the whole periodic table. The pi癡ce de r矇sistance in the collection is a series of dimensional analysis questions in Integrable Nonlinear Partial Differential Equations with no dimensions existing a priori. Solved problems include the relationship between the size and the speed of solitons of the Korteweg-de Vries equation and an expression for the oscillation period of a Nonlinear Schr繹dinger breather as a function of its width.A new theme that appears in the second edition are the rare and exotic methods in elementary quantum mechanics. The new chapter covers quantum-mechanical supersymmetry, power index method, scale invariance, self-similarity, and circle inversion.
Quantum Optics
This revised new edition gives a unique and broad coverage of basic laser-related phenomena that allow graduate students, scientists and engineers to carry out research in quantum optics and laser physics. It covers quantization of the electromagnetic field, quantum theory of coherence, atom-field interaction models, resonance fluorescence, quantum theory of damping, laser theory using both the master equation and the Langevin theory, the correlated emission laser, input-output theory with applications to non-linear optics, quantum trajectories, quantum non-demolition measurements and generation of non-classical vibrational states of ions in a Paul trap. This fourth edition provides a new chapter on weak measurement, as well as a new chapter on complementarity. There is also new material included for atom optics and new problems have been added. Each topic is presented in a unified and didactic manner, and is accompanied by specific problems and hints to solutions to deepen the knowledge.
Dimension Six
Dimension Six is about physics, but it's about more than physics. It is a captivating exploration that transcends the boundaries of traditional physics and offers a fresh perspective on the enigmatic relationship between the physical world and consciousness.Modern physics, with its awe-inspiring revelations, beckons us to question the very fabric of reality. Why does space impose a cosmic speed limit, confining objects to move slower than light? How does mass transform and time warp under extreme velocities? The elusive nature of particles and the peculiarities of acceleration versus velocity in our daily experiences only deepen the intrigue. These phenomena, well-charted yet perpetually dazzling, happen at extreme dimensions - the very fast, the very small, the very massive, and the very distant. But the crux of these mysteries lies in the connection to the observer, to consciousness itself. In the absence of an observer, the existence of a material object becomes a perplexing quandary.Dimension Six beckons us to revisit our understanding of dimensions and their relationship with consciousness. Once perceived as fixed structures of an external world, dimensions are now revealed as fluid, bending, and merging realms at their extremes, courtesy of relativity theory and quantum mechanics. Is a dimension an intrinsic element of the material universe, or is it a cornerstone of consciousness itself?This book is written for those with some exposure to physical science - from basic physics courses to advanced Ph.D. studies. But most importantly, it is an invitation to those willing to venture beyond conventional thinking. Dimension Six sparks a paradigm shift by challenging the fundamental assumptions underpinning our comprehension of consciousness and physical reality.If you seek an insightful exploration of the perplexities in modern physics and a revelation of why we perceive the world as external and material, then this book promises not only intrigue but also enlightenment.

Magnetic Alchemy
Magnetic alchemy delves into the mesmerizing science behind iron's inherent attraction to magnets, uncovering the intricate chemistry orchestrating this magnetic symphony. At its core, this captivating phenomenon stems from the elemental composition and atomic structure of iron, intertwining with the laws of magnetism.Iron, a versatile metal abundant in the Earth's crust, possesses a unique atomic arrangement that endows it with magnetic properties. Its atomic structure allows for unpaired electrons, lending itself to ferromagnetism-the ability to become magnetized when exposed to a magnetic field. Within this atomic dance, the alignment of these unpaired electrons contributes to the magnetic personality of iron.The magnetic journey of iron converges with the principles of magnetism, where each magnetic field acts as a conductor orchestrating the alignment of iron's atomic magnets. When a magnetic field embraces a piece of iron, it nudges these atomic magnets into alignment, generating a magnetic force within the material. This alignment persists even after the external magnet is removed, creating a magnetic field in the iron itself-a state known as induced magnetism.However, the magic doesn't stop there. Heat plays a role in this magnetic ballet. At a specific temperature called the Curie point, iron loses its magnetic properties. The intense thermal energy disrupts the alignment of the atomic magnets, causing them to jostle and lose their magnetic coherence.The interplay of heat, atomic structure, and magnetic fields reveals the alchemical secrets behind iron's magnetic allure. This captivating chemistry doesn't solely fascinate scientists but also forms the bedrock of numerous technological advancements, from electromagnets powering machinery to the magnetic storage in our everyday devices.Understanding the magnetic enchantment of iron not only unravels the mysteries of fundamental physics and chemistry but also opens pathways to innovate and engineer magnetic materials, revolutionizing industries and amplifying our technological prowess. Magnetic alchemy, where the dance of atoms and fields converges, continues to illuminate the fascinating interplay of elements that underpin the captivating attraction of iron to magnets.

Collected Writings of Edward Leedskalnin
2024 Reprint of Two Separate Publications Published in a Single Volume. Facsimile of the original edition and not reproduced with Optical Recognition Software. The Collected Writings of Edward Leedskalnin is a compilation of two of Leedskalnin's works, A Book in Every Home and Magnetic Current. This eccentric sculptor and amateur scientist devoted most of his life to creating a large complex of megalithic stones that he quarried and carved himself.Leedskalnin purchased a modest plot in Florida and began removing and relocating enormous stones from his land, moving them into position, and carving them entirely on his own as far as we know. The pieces include sculptures and carved stone furniture, as well as a two-story tower that served as his living quarters. Due to the scale of the project, some have dubbed it "Florida's Stonehenge." While it's unclear how Leedskalnin was able to complete it, it is all the more impressive considering his small stature and questionable health.Leedskalnin also spent two years testing magnets and recording his findings. These experiments would form the basis of Magnetic Current, published in 1945. In the book, Leedskalnin argues that electricity and magnetism are not separate phenomena but are instead two aspects of the same fundamental force, which he calls "magnetic current." He also proposes a new model of atomic structure and suggests that the fundamental particles of matter are tiny magnets that are constantly in motion.Leedskalnin presents a variety of experiments throughout the book, many of which involve the manipulation of magnetic fields using simple items like various magnets, car batteries, light bulbs, and coils of wire. He believed that his discoveries could provide insights into the mysteries of the universe, including the relative positions of the celestial bodies. Both works demonstrate Leedskalnin's unique view of the world and his eccentric personality. Though certainly eccentric, the two works offer an intriguing glimpse into the mind of a self-taught philosopher and inventor who had a unique perspective on the world around him.
Background Independence in Classical and Quantum Gravity
It is often claimed that Einstein's magnum opus---his 1915 theory of General Relativity---is distinguished from other theories of space and time in virtue of its background independence. It's also often claimed that background independence is an essential feature of any quantum theory of gravity. But are these claims true? This book aspires to offer definitive answers to both of these questions, by (a) charting the space of possible definitions of background independence, and (b) applying said definitions to various classical and quantum theories of gravity. The outcome, in brief, is as follows: General Relativity is not unique by virtue of its background independence (and, indeed, fails to be background independent on some popular definitions); moreover, the situation in the case of quantum theories of gravity is delicate, because (i) there are viable such theories which (by some accounts, at least) fail to be background independent, but also (ii) theories (e.g. perturbative string theory) which have often been dismissed for (allegedly) being background dependent in fact, on many accounts, are better classified as background independent. In giving these answers in rigorous detail, this book seeks to elevate the standards and generality of future discussions of background independence in the foundations of spacetime theories.
Solitonic Neural Networks
This book delves into optics and photonic materials, describing the development of an intelligent all-optical system capable of replicating the functional building blocks of the biological brain. Starting with an analysis of biological neuronal dynamics and traversing the state of the art of neuromorphic systems developed to date, the book arrives at a description of neural networks realized through spatial soliton technology.After a brief introduction to the biology of neural networks (Chapter 1), the book delves into the description of the neuromorphic problem emphasizing the peculiarities of optical hardware developed to date. (Chapter 2). Chapter 3 is dedicated to the description of psychomemories, which represent the modeling of human learning according to the theories of modern neuro-psychology. This chapter provides the prerequisites for understanding how solitonic neural networks (SNNs) are able to learn and how they approach biological models. Chapter 4 focuses on the experimentation of solitonic optic neurons in thin layers of lithium niobate. Optical techniques for supervised and unsupervised learning are discussed. The entire chapter is accompanied by theoretical, simulative and experimental results. This chapter explains how an X-junction neuron is able to establish synapses, modify them, or erase them. The erasure of solitonic structures represents an important innovation in the field of nonlinear optics. Finally, Chapter 5 reports on the implementation of a network of neurons capable of processing information and storing it exactly as a human episodic memory does. The chapter ends with a number of insights into the lines of research that are currently being pursued on the basis of the results obtained.The book is meant for graduate students and researchers in the fields of optics, photonic applications, and biology. However, the main beneficiaries of this book are senior researchers in the fieldof nonlinear optics and artificial intelligence. To fully understand the results, it is important to have a basic knowledge of optical physics and neuron biology.
Theory of Electromagnetoelasticity
Theory of Electromagnetoelasticity presents a systematic and unique treatment of elastic, electric and magnetic interactions in solids including various thermal and dissipative effects such as viscoelasticity and electrical conduction. In this book, a general and nonlinear continuum theory is constructed. The fundamental building blocks of the theory -- the electromagnetic body force, couple and power -- are calculated from a multi-continuum model consisting of a lattice continuum for elastic deformation, a bound charge continuum for electric polarization, a circulating current continuum for magnetization, and a free charge fluid for electrical conduction. The multi-continuum model is simpler than the common charged particle model and reveals the underlying physics from a unique angle. The complete set of Maxwell's equations for the electromagnetic fields is included without the widely used quasistatic approximations of the electric and/or magnetic fields. The theory established can be used to describe different kinds of interactions between acoustic and optical fields or waves. Some linear problems are analyzed as examples to show some of the simplest elastic and electromagnetic couplings.
Spaces and Dimensions of Quantum Fields
What defines the essence of my technical and highly conceptual book is the fact that it renders Quantum Field Theory accessible to an as wide a circle of readers as possible without compromising the theory's physical and mathematical rigour. Not only will my book, for that matter, be of interest to research physicists and to graduate students of physics, it will also be of interest to undergraduate students of physics and to the non-academic but interested, discriminating and dedicated readers. Whereas all other published books and textbooks address either the experts, or the graduate students in Quantum Field Theory, my conceptual analysis addresses all readers: From academic professionals, especially those researchers who are active in other fields (condensed matter physics, atomic and laser physics, quantum mechanics, mathematics, chemistry, computer science, engineering, etc.), to the non-academic readers who may not be literate in mathematics and physics but have a capacity for conceptual abstraction and are willing to consistently apply it in order to understand Quantum Field Theory.
Optical Methods for Managing the Diabetic Foot
This book discusses optical technologies for Diabetic Foot management. It combines the current medical literature review with an overview of the technology and physics behind it. Thus, it is a single-source introduction to the topic. It can also be used as a reference source and practical guide for the use of technology. The particular focus is on low-cost technologies, including hyperspectral imaging, thermography, and endogenous bacterial fluorescence. Moving diagnostic modalities closer to the patient (e.g., primary care) allows the disease to be detected at an earlier stage, thus improving outcomes. However, while some optical technologies are available commercially, they have not received wide clinical adoption due to gaps in knowledge translation to mainstream medicine. This book aims to narrow this gap with practical illustrations. The book will be of interest to a broad range of healthcare professionals, clinical researchers, engineers, and decision-makers, who are dealing with complications of diabetes.Key Features: Reviews the current state of technologies Provides a practical guide with practical considerations and illustrations Supplies a 360-degree view of the combination of clinical information with a technology background and primers on physics and engineering

Optical Polymer Waveguides
Light signals in optical waveguides can be used to transmit very large amounts of data quickly and largely without interference. In the industrial and infrastructural sectors, e.g. in the automotive and aerospace industries, the demand to further exploit this potential is therefore increasing. Which technologies can be used to effectively integrate systems that transmit data by means of light into existing components? This is a central question for current research. So far, there have been some technical limitations in this regard. For example, it is difficult to couple the signal of an optical waveguide to other optical waveguides without interruption. There is also a lack of suitable fabrication technologies for three-dimensional waveguides, as well as design and simulation environments for 3D opto-MID. This book addresses these and other challenges.

Tiny Quantum, Giant Revolution
The first industrial revolution was accompanied by the emergence of the School of Engineering, the second brought about the School of Electrical Engineering, and the third digital revolution led to the School of Information. It is now obvious that the change in this quantum revolution must lead to the emergence of the School of Quantum Science and Technology. Quantum technology can develop comprehensively through the integration of science, technology, engineering, art and mathematics (STEAM). In 1925, Heisenberg developed the Matrix Mechanics, cracking the mysteries of the Quantum world. Coinciding with the 100th anniversary of Matrix Mechanics, in 2024, the General Assembly of the United Nations proclaimed 2025 the 'International Year of Quantum Science and Technology, ' along with a year-long initiative celebrating the profound impacts of quantum science on technology, culture, and our understanding of the natural world.This book outlines the importance of the 'Second Quantum Revolution, ' introduces quantum computers, quantum communications, and quantum sensors, and then provides a framework for the emergence of the quantum Internet of Things. What basic quantum literacy should modern citizens have in this era? The 'Second Quantum Revolution, ' where quantum knowledge and engineering technology are once again combined, will provide faster, more effective, and more sensitive quantum facilities to accelerate cross-field exploration, and will also make human life more comfortable and convenient than ever before.In the 'First Quantum Revolution' in the 20th century, humans learned quantum science from nature and used existing materials to make quantum components. In the 'Second Quantum Revolution' in the 21st century, humans further used quantum science to construct quantum engineering. We now make materials and components that are not found in nature and assemble new quantum machines to benefit mankind! This is the stage of a glorious quantum era, which is a hundred times more brilliant than the past classical physics era.

Spaces and Dimensions of Quantum Fields
The essence of this technical and highly conceptual book is inherent in its capacity to render Quantum Field Theory accessible to an as wide a circle of readers as possible without compromising the theory's physical and mathematical rigour. Not only will this book, for that matter, be of interest to research physicists and to graduate students of physics, it will also be of interest to undergraduate students of physics and to the non-academic but interested, discriminating and dedicated readers. Whereas all other technical books and textbooks address either the experts, or the graduate students in Quantum Field Theory, the conceptual analysis in this book addresses all readers: From academic professionals, especially those researchers who are active in other fields (condensed matter physics, atomic and laser physics, quantum mechanics, mathematics, chemistry, computer science, engineering, etc.), to the non-academic readers who may not be literate in mathematics and physics but have a capacity for conceptual abstraction and are willing to consistently apply it in order to understand Quantum Field Theory.
Basic Concepts of Modern Physics
"Only in the course of this investigation may we hope to uncover the true function of thinking in physics. In any case, in even the simplest parts of physical science many conceptual distinctions lie hidden, whether we speak of phenomena or effects. Who would deny that the rainbow is a single thing rather than merely the play of refraction and dispersion summed over countless drops?" -- Georg UngerBasic Concepts of Modern Physics is an essential introduction for all those who are interested in gaining a better understanding of modern physics. In this unique text, Georg Unger provides clear descriptions of the conceptual bases of twentieth-century physics, including quantum mechanics, particles, and relativity theory, as well as other aspects relating to key physical concepts to phenomena.Recognizing that quantum mechanical phenomena occur at a boundary between the experienced world and a concurrent world of "subnature" that is not perceptible to the senses, Dr. Unger provides a radical, non-reductionist concept of modern physics that is open to spiritual understanding. "We should go into a short contemplation of certain habits of thinking and ask: What expresses itself in this adherence to the nineteenth-century idea of matter? To say it radically--and thereby naturally be open to misunderstanding--it is a weakness of thinking characteristic of our times." -- Georg UngerThis book is a translation from German of Grundbegriffe der modernen Physik Quanten, Teilchen, Relativit瓣t: Vom Bilden physikalischer Begriffe - Teil III (Verlag Freies Geistesleben, 1967). An earlier English edition was published as Forming Concepts in Physics (Parker Courtney Press, 1995).

Broadcasting in Ireland
Broadcasting in Ireland (1978) outlines the historical and sociological background of Ireland to place the progress of its broadcasting service in the context of its post-independence development. It analyses the difficulties of running public service broadcasting financed by both licence fee and advertising, and competing in half its television reception area with two of the premier broadcasting systems in the world. With regular broadcasting beginning with Independence, its development was inevitably bound up with the process of building the political, economic and social framework of the new State, and this book closely examines how the Irish broadcasting system coped with the attending economic, cultural and political difficulties.

The Mathematical Radio
How a modern radio works, told through mathematics, history, and selected puzzles The modern radio is a wonder, and behind that magic is mathematics. In The Mathematical Radio, Paul Nahin explains how radios work, deploying mathematics and historical discussion, accompanied by a steady stream of intriguing puzzles for math buffs to ponder. Beginning with oscillators and circuits, then moving on to AM, FM, and single-sideband radio, Nahin focuses on the elegant mathematics underlying radio technology rather than the engineering. He explores and explains more than a century of key developments, placing them in historical and technological context. Nahin, a prolific author of books on math for the general reader, describes in fascinating detail the mathematical underpinnings of a technology we use daily. He explains and solves, for example, Maxwell's equations for the electromagnetic field. Readers need only a familarity with advanced high school-level math to follow Nahin's mathematical discussions. Writing with the nonengineer in mind, Nahin examines topics including impulses in time and frequency, spectrum shifting at the transmitter, the superheterodyne, the physics of single-sideband radio, and FM sidebands. Chapters end with "challenge problems" and an appendix offers solutions, partial answers, and hints. Readers will come away with a new appreciation for the beauty of even the most useful mathematics.
