"The Universal One" by Walter Russell is an ambitious and comprehensive work that endeavors to blend the realms of science, philosophy, and spirituality into a singular, cohesive theory of the universe.Published in 1926, Russell's book presents a visionary perspective on the nature of matter, energy, and consciousness, proposing a universe governed by laws of balance and rhythmic cycles. Through intricate diagrams and detailed explanations, Russell challenges the conventional scientific paradigms of his time, advocating for a deeper, more unified understanding of the cosmos. His ideas, though not widely embraced by the scientific community, have inspired a dedicated following and continue to spark interest for their bold attempt to reconcile the physical with the metaphysical, offering a unique lens through which to view the mysteries of existence.

How is faster-than-light related to back-in-time?Albert Einstein knew already in the early 1900s, when he first published his famous paper about the constancy of the speed of light, that not only did this constancy imply that mass contains energy (E = m c squared), but that faster-than-light motion could lead to paradoxes -- some that seemed to involve backwards time travel.What are these paradoxes? Why is light and its speed relevant? This book will lead you through an obstacle course of conundrums and oddities, building up your understanding of how light's speed creates simple but mind-expanding paradoxes -- one conceptual riddle at a time.This is not your average popular science book. This is also not a textbook. This book takes one theme -- the universally constant speed of light -- and shows how it may appear compromised on scales from the quantum mechanics of the very small to the cosmology of the very large, and the resulting surprising implications can result.

Better Eyesight Without Glasses is not only the definitive source for the classic Bates Method, it is in itself a remarkable phenomenon. Dr. William H. Bates’s revolutionary and entirely commonsensical theory of self-taught improved eyesight has helped hundreds of thousands of people to triumph over normal defects of vision without the mechanical aid of eyeglasses. If you think that your eyesight could be made better by natural methods, you are right.After years of experimentation, Dr. Bates came to the conclusion that many people who wore glasses did not need them. He gradually and carefully developed a simple group of exercises for improving the ability of the eyes themselves to see, eliminating the tension caused by poor visual habits that are the major cause of bad eyesight. These exercises are based on the firm belief that it is the natural function of the eyes to see clearly and that anyone, child or adult, can learn to see better without glasses. Featuring an eye chart for improving your vision at home, The Bates Method for Better Eyesight Without Glasses will give you all the guidance you need for relaxed and improved vision. Read more

Feynman’s bestselling introduction to the mind-blowing physics of QED—presented with humor, not mathematicsCelebrated for his brilliantly quirky insights into the physical world, Nobel laureate Richard Feynman also possessed an extraordinary talent for explaining difficult concepts to the public. In this extraordinary book, Feynman provides a lively and accessible introduction to QED, or quantum electrodynamics, an area of quantum field theory that describes the interactions of light with charged particles. Using everyday language, spatial concepts, visualizations, and his renowned Feynman diagrams instead of advanced mathematics, Feynman clearly and humorously communicates the substance and spirit of QED to the nonscientist.With an incisive introduction by A. Zee that places Feynman’s contribution to QED in historical context and highlights Feynman’s uniquely appealing and illuminating style, this Princeton Science Library edition of QED makes Feynman’s legendary talks on quantum electrodynamics available to a new generation of readers.

The most important things in life are our health and happiness. Yet most of us are neither healthy nor happy. We have been led to believe that if we think ahead and make the right choices, we can manifest our dreams. Yet despite our best efforts, we still have more disease and discontent than ever before. Is it possible that our essential ideas about life are flawed? We are all aware of the impact of sunlight on a plant's growth and development. But few of us realize that a plant actually "sees" where light is emanating from and positions itself to be in optimal alignment with it. This phenomenon, however, is not just occurring in the plant kingdom - humans are also fundamentally directed by light. In Luminous Life, Dr. Jacob Israel Liberman integrates scientific research, clinical practice, and direct experience to demonstrate how the luminous intelligence we call light effortlessly guides us toward health, contentment, and a life filled with purpose.

Light enables us to see the world around us. Our sense of sight provides us with direct information about space and time, the physical arrangement of the world, and how it changes. This almost universal shared sensation of vision has led to a fascination with the nature and properties of light across the ages. But the light we see is just a small part of the whole spectrum of electromagnetic radiation, ranging from radio waves to gamma rays.In this Very Short Introduction Ian Walmsley discusses early attempts to explain light, and the development of apparently opposing particulate and wave theories by scientists such as Isaac Newton and Christiaan Huygens. He shows how light was recognized as an electromagnetic wave in the 19th century, and the development of the quantum mechanics view of wave-particle duality in the 20th century. He also describes the many applications of light, domestic and scientific, such as microwaves, DVDs, and lasers. We now use the whole range of electromagnetic radiation to peer both into the human body and deep into space. Turning to the future of optics, Walmsley concludes by looking at some of the most exciting new developments using quantum light sources in communications and computing.ABOUT THE SERIES:The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable. Read more

The author challenges the conventional wisdom that light is just another physical entity. He outlines a new role of light in the formation of the three main components of the universe - God, still light; the dual light waves emanated from God and the material world both organic and inorganic which is made of light bent into various spiral forms. Reading this book "is an important step toward understanding both the intellectual and spiritual balances that exist in the universe." Read more

Artist, technologist, and philosopher James Bridle’s Ways of Being is a brilliant, searching exploration of different kinds of intelligence―plant, animal, human, artificial―and how they transform our understanding of humans’ place in the cosmos.What does it mean to be intelligent? Is it something unique to humans or shared with other beings―beings of flesh, wood, stone, and silicon? The last few years have seen rapid advances in “artificial” intelligence. But rather than a friend or companion, AI increasingly appears to be something stranger than we ever imagined, an alien invention that threatens to decenter and supplant us.At the same time, we’re only just becoming aware of the other intelligences that have been with us all along, even if we’ve failed to recognize or acknowledge them. These others―the animals, plants, and natural systems that surround us―are slowly revealing their complexity, agency, and knowledge, just as the technologies we’ve built to sustain ourselves are threatening to cause their extinction and ours. What can we learn from them, and how can we change ourselves, our technologies, our societies, and our politics to live better and more equitably with one another and the nonhuman world?The artist and maverick thinker James Bridle draws on biology and physics, computation, literature, art, and philosophy to answer these unsettling questions. Startling and bold, Ways of Being explores the fascinating, strange, and multitudinous forms of knowing, doing, and being that make up the world, and that are essential for our survival.Includes illustrations Read more

One of Smithsonian's Favorite Books of 2018One of Forbes's 2018 Best Books About Astronomy, Physics and MathematicsOne of Kirkus's Best Books of 2018 The intellectual adventure story of the "double-slit" experiment, showing how a sunbeam split into two paths first challenged our understanding of light and then the nature of reality itself--and continues to almost 200 years later.Many of science's greatest minds have grappled with the simple yet elusive "double-slit" experiment. Thomas Young devised it in the early 1800s to show that light behaves like a wave, and in doing so opposed Isaac Newton. Nearly a century later, Albert Einstein showed that light comes in quanta, or particles, and the experiment became key to a fierce debate between Einstein and Niels Bohr over the nature of reality. Richard Feynman held that the double slit embodies the central mystery of the quantum world. Decade after decade, hypothesis after hypothesis, scientists have returned to this ingenious experiment to help them answer deeper and deeper questions about the fabric of the universe.How can a single particle behave both like a particle and a wave? Does a particle exist before we look at it, or does the very act of looking create reality? Are there hidden aspects to reality missing from the orthodox view of quantum physics? Is there a place where the quantum world ends and the familiar classical world of our daily lives begins, and if so, can we find it? And if there's no such place, then does the universe split into two each time a particle goes through the double slit?With his extraordinarily gifted eloquence, Anil Ananthaswamy travels around the world and through history, down to the smallest scales of physical reality we have yet fathomed. Through Two Doors at Once is the most fantastic voyage you can take. Read more

This incisive text provides a basic undergraduate-level course in modern optics for students in physics, technology and engineering. The first half of the book deals with classical physical optics; the second principally with the quantum nature of light. Chapters 1 and 2 treat the propagation of light waves, including the concepts of phase and group velocities, and the vectorial nature of light. Chapter 3 applies the concepts of partial coherence and coherence length to the study of interference, and Chapter 4 takes up multiple-beam interference and includes Fabry-Perot interferometry and multilayer-film theory. Diffraction and holography are the subjects of Chapter 5, and the propagation of light in material media (including crystal and nonlinear optics) are central to Chapter 6. Chapters 7 and 8 introduce the quantum theory of light and elementary optical spectra, and Chapter 9 explores the theory of light amplification and lasers. Chapter 10 briefly outlines ray optics in order to introduce students to the matrix method for treating optical systems and to apply the ray matrix to the study of laser resonators.Many applications of the laser to the study of optics are integrated throughout the text. The author assumes students have had an intermediate course in electricity and magnetism and some advanced mathematics beyond calculus. For classroom use, a list of problems is included at the end of each chapter, with selected answers at the end of the book. Read more

This comprehensive guide to colour science presents A. H. Munsell's foundational texts on colour theory and practice in a true celebration of both art and science.Albert Henry Munsell was a pioneer of colour theory. His Colour Notation established theories for categorising colour around three dimensions: hue, value (lightness), and chroma (purity). These elements were proposed to produce any particular colour or differentiate between those of the same character. First published in 1905, Munsell's innovative theory offered insights into colour harmony, relationships, and the psychological impact of colours. It spurred significant advancements in colour science, art, and design, standing as a cornerstone text alongside those published by Michel Chevreul and Ogden Rood.This new edition from Art Meets Science combines Munsell's seminal A Colour Notation with all fifteen full-colour plates from Atlas of the Munsell Color System, an introduction by Munsell, and an essay on colour by Bonnie E. Snow. An essential colour manual for those studying colour theory or with an interest in colour application, colour behaviours, and the history of colour theory. Read more

“ When we look at the world around us, on Nature, we are impressed with its beauty and grandeur. Each thing we perceive, though it may be vanishingly small, is in itself a world, that is, like the whole of the universe, matter and force governed by law,—a world, the contemplation of which fills us with feelings of wonder and irresistibly urges us to ceaseless thought and inquiry. But in all this vast world, of all objects our senses reveal to us, the most marvelous, the most appealing to our imagination, appears no doubt a highly developed organism, a thinking being. If there is anything fitted to make us admire Nature’s handiwork, it is certainly this inconceivable structure, which performs its innumerable motions of obedience to external influence. To understand its workings, to get a deeper insight into this Nature’s masterpiece, has ever been for thinkers a fascinating aim, and after many centuries of arduous research men have arrived at a fair understanding of the functions of its organs and senses...” N.
