Let There Be Light The Story Of Light From Atoms To Galaxies

This book is the first of its kind devoted 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 the 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 OCyHistorical InterludesOCO 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.The second edition has been revised and made more accessible to the general reader. Whenever possible, the mathematical material of the first edition has been replaced by appropriate text to give a verbal account of the mystery of the phenomenon of light and how its understanding has developed from pre-historic to present times. The emphasis is on reading for interest and enjoyment; formulae or equations which underpin and reinforce the argument are presented in a form which does not interfere with the flow of the text.The book will be of interest to students and teachers, as well as general readers interested in physics.

Topics are, nevertheless, treated with a good degree of rigour … This may be the book that affords the struggling student a glimpse of the beauty that makes the serious study of physics so worthwhile.” (see full review) Professor Frank Imbusch National University of Ireland “Compared to the first edition, the mathematics demands have been reduced, and the last chapter has been expanded to include the potential detection of the Higgs boson in 2012. Historical interludes continue to be distinct from the main development, and the illustrations provide charming entertainment. The revisions make the main text, already instructive and well developed, more accessible and engaging to general audiences.”CHOICE

In Let There Be Light, Howard Smith, a research astrophysicist and traditionally observant Jew, explores how modern scientific understandings of the cosmos complement Judaism's ancient mystical theology, the Kabbalah. He argues that science and religion are not only compatible, but that a healthy, productive dialogue between the two sheds light on ethics, free will, and the nature of life, while at the same time rejecting fundamentalist misinterpretation and the pseudoscience of creationism. Written for a general audience, yet supported by the most current and accurate scientific research, the book discusses topics such as modern quantum mechanics and mystical notions of awareness; how Kabbalah's ten sefirot mirror the developing phases of an inflationary universe; and the surprising parallels that exist between the Big Bang theory and Kabbalah's origin theory. Smith delves into complex ideas without resorting to jargon or mathematical equations, creating an intelligent, authoritative work accessible to all readers.

This book is one of a kind. It traces the history of human awareness of God and belief back to its earliest roots, long before the Bible, the Koran, the Upanishads and other writings. It shows how the foundation for belief in God was contained within the instant of creation itself. Scientists call this the big bang. It shows that as the universe developed there came a point in human development where we had the capability to begin to be aware of an afterlife. These ideas were primitive by our standards today but they served to create a solid foundation for increasing complex and more thorough understandings of who God is and our relationship with Him. This book covers the well known axial age where there was a watershed or flood of prophets and holy men who advanced understandings of both philosophy and theology and science in the hundreds of years before the coming of Jesus Christ. In a real sense they prepared the way for God’s son and His gospel. It is these men who changed the course of human understanding of God with new revolutionary ideas that advanced the self revelation of God to humankind. The last part of the book looks at religion today and how we got here and ends with God’s view of humanity as we constantly strive toward God on our individual spiritual journeys.

Light begins at Stonehenge, where crowds cheer a solstice sunrise. After sampling myths explaining First Light, the story moves on to early philosophers' queries, then through the centuries, from Buddhist temples to Biblical scripture, when light was the soul of the divine. Battling darkness and despair, Gothic architects crafted radiant cathedrals while Dante dreamed a "heaven of pure light." Later, following Leonardo's advice, Renaissance artists learned to capture light on canvas. During the Scientific Revolution, Galileo gathered light in his telescope, Descartes measured the rainbow, and Newton used prisms to solidify the science of optics. But even after Newton, light was an enigma. Particle or wave? Did it flow through an invisible "ether"? Through the age of Edison and into the age of lasers, Light reveals how light sparked new wonders--relativity, quantum electrodynamics, fiber optics, and more. Although lasers now perform everyday miracles, light retains its eternal allure. "For the rest of my life," Einstein said, "I will reflect on what light is." Light explores and celebrates such curiosity.
