In this all-encompassing work, one of the most famous science fiction as well as nonfiction writers of our time explores the subject of light and shows how it has shaped every aspect of our existence.From the creation of life to the exploration of the heavens and the stars, from the origins of the earth to the possibility of life on distant planets, BenBova unveils the beauty and science behind the phenomenon of light. Dr. Bova masterfully explains how light affects us every day of our lives, from our religions to our sex drives, as well as how we use light in art, science, industry, entertainment, cosmetics, jewelry, and much more.Why do people kiss with their eyes closed?What exactly is quantum physics?Why is it difficult to swat a mosquito?How to lasers work?What do we "see" when we dream?Praise for The Story of Light:"The enlightenment of discoveries and the brilliance of Ben Bova combine to enable our minds to glimpse the majesty of the infinite worlds of light in the universe."—Buzz Aldrin"Superbly written — a banquet of topics served by a master literary chef!"—Bill Pogue, astronaut_"The Story of Light is a lighthearted, enlightened romp through many facets of human experience, reflected and refracted through Bova's bright, polychromatic mind."—David Grinspoon, Principle Scientist, Southwest Research Institute and author of Venus Revealed About the AuthorBen Bova is the author of nearly 125 futuristic novels and nonfiction books about science and high technology. In his various writings, Dr. Bova has predicted the Space Race of the 1960s, solar power satellites, the discovery of organic chemicals in interstellar space, virtual reality, human cloning, the Strategic Defense Initiative (Star Wars), the advent of international peacekeeping forces, the discovery of ice on the Moon, electronic book publishing and zero-gravity sex. Dr. Bova received the Lifetime Achievement Award of the Arthur C. Clarke Foundation in 2005, "for fueling mankind's imagination regarding the wonders of outer space." His 2006 novel TITAN received the John W. Campbell Memorial Award for best novel of the year, and he received the 2008 Robert A. Heinlein Award "for his outstanding body of work in the field of literature." Dr. Bova has been involved in science and high technology since the very beginnings of the space age. President Emeritus of the National Space Society and a past president of Science Fiction Writers of America, Inc., Dr. Bova was elected a Fellow of the American Association for the Advancement of Science and has been a member of the Arizona Astronomy Board. He is a columnist for the Naples Daily News and a widely-popular lecturer. Earlier in his career, he was an award-winning editor and an executive in the aerospace industry. He has worked with film makers and television producers such as Woody Allen, George Lucas, and Gene Roddenberry. His "Grand Tour" novels, including his award-winning TITAN, show how the human race will expand through the solar system, opening a new era of wealth and opportunity -- and conflict. His nonfiction books, such as IMMORTALITY and FAINT ECHOES, DISTANT STARS have been honored by organizations such as the American Librarians' Association and the American Association for the Advancement of Science. He has won six Science Fiction Achievement Awards (Hugos) and many other awards for writing. Read more

In a world where scientific principles are often regarded as immutable truths, the time has come to revisit the foundational theories that have shaped our understanding of the universe. As a filmmaker, my lens has captured the wonders and mysteries of the physical world, but it is through the lens of critical inquiry that I now examine the claims of modern physics.This book is not just a critique; it is an invitation to question, to probe, and to rethink what we have long accepted as truth. For over a century, Einstein's theory of relativity has been celebrated as one of the cornerstones of modern science. Yet, as with all theories, it is not immune to scrutiny. The elegant equations and profound implications of Relativity have, in many ways, defined the scientific narrative of the 20th and 21st centuries. But what if that narrative is incomplete? What if the very framework that underpins our understanding of space, time, and gravity contains inherent contradictions or overlooked limitations?As you turn these pages, you will embark on a journey that challenges the established dogmas of physics. We will explore not only the potential failings of relativity but also the broader issues plaguing contemporary scientific thought. From quantum mechanics to cosmology, the theories that govern our understanding of reality will be laid bare, and their inconsistencies brought to light.This book is not an attack on science, but a call to elevate it. To push the boundaries of knowledge, we must first recognize where they lie. It is my hope that this work will inspire a new generation of thinkers—scientists, philosophers, and curious minds alike—to approach the mysteries of the universe with fresh eyes and an open mind.Chapter by chapter this book provides a general outline for each topic followed by an analysis of their limitations and weaknesses, often providing alternative scenarios for these phenomena.Join me as we delve into the complexities and controversies that have long been ignored or dismissed. The truth, after all, is not found in the comfort of consensus but in the courage to challenge it. Read more

La dottrina segreta è una delle opere fondamentali di HPB che, insieme a Iside Svelata, costituisce la “summa” del pensiero teosofico che, tra l’altro, contribuì a far nascere e consolidarsi.Commentando le numerose stanze di Dzyzan, un antichissimo manoscritto tibetano da lei rinvenuto, tradotto e commentato, il testo parla dell’evoluzione occulta dell’universo e dell’uomo con l’obiettivo, come ben descritto nell’introduzioone, di: «[...] dimostrare che la Natura non è "una fortuita combinazione di atomi", ed assegnare all'uomo il suo giusto posto nello schema dell'Universo;risollevare dalla degradazione le verità arcaiche che sono alla base di ogni Religione per mettere in rilievo, fino ad un certo punto, l'Unità fondamentale dalla quale esse tutte derivano;ed infine dimostrare che il lato occulto della Natura non è mai stato studiato dalla scienza della civiltà moderna.»Primo di due volume, Cosmogenesi è l’esplosione della immensa cultura di HPB, con numerose ed importantissime connessioni alle culture orientali, induiste, greche, romane dimostrando, citando solo una delle conclusioni a cui arriva il testo, che l'Universo si evolve secondo il suo Piano ideale, che sussiste dall'Eternità nell'Incoscienza del «Parabrahman».Un testo importante, utile per tutti coloro che sono alla ricerca dell’origine del nostro mondo e dell’umanità in esso contenuta.

In 1900 Max Planck provided the first step by introducing quantization in the processes of absorption and emission of energy by matter. Five years later, Einstein went one step further, demonstrating that quantization is also present in the propagation of an electromagnetic field, so it is an intrinsic component of an electromagnetic field. In other words, he introduced the concept of "photon".Marcello Colozzo, a graduate in Physics, has been involved in online teaching of Mathematics and Physics since 2008 through the Extra Byte website where "simulations" are performed in the Mathematica computing environment. In recent years he has published various articles on mathematical physics and collaborates with the Electronic Open Source magazine. An avid reader of cyberpunk fiction, he has attempted to transition into "cyber writer" status by publishing various anthologies of short stories. Read more
