Download or read book Beyond Light Detection written by Khadija and published by Tredition Gmbh. This book was released on 2024-07-09 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The retina, often thought of as a simple light detector, is in fact a marvel of biological engineering. While it does initiate the process of vision by capturing light, its true magic lies beyond. Rods and cones, the retina's light-sensitive cells, translate light into electrical signals, but the story doesn't end there. These signals are then processed within the retina itself, allowing for functions like night vision, color perception, and depth perception. This intricate processing power shapes how we experience the world - from appreciating a vibrant sunset to navigating a busy street. Understanding the retina's complexities opens the door to not only appreciating the miracle of sight, but also to developing solutions for vision problems, ensuring a clear window to our world.

Download or read book The Light written by J. Powers and published by iUniverse. This book was released on 2007 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a cosmos where the physical constants of nature are fine tuned to unimaginable precision to permit the existence of life, the giant US/Chinese radio telescope on the far side of the moon detects no technological civilizations. Why? Fantasies of space travel to the stars and cheap limitless energy have, by the mid-21st century, proven to be just that. Fantasies. Upon this stage appears an American Indian woman in the grip of a delusion that her son is Quetzalcoatl, an ancient Meso-American God whom she has pursued in devotion across the centuries. A teacher at the shabby Apache Indian reservation elementary school recognizes the boy as probably the greatest mathematical genius in human history. A shaman senses in the man the reality of myth and fulfillment of ancient prophecy. None comprehend the staggering dimensions of his true destiny. The Light is a psychedelic adventure of a genius who must choose between surrender to delusion, or freedom from superstition and madness to fall in love and live his own life as the greatest particle physicist of his age. In so doing he unleashes forces that give substance to ancient myths and challenge the limits of human imagination.
Download or read book Supernova written by Or Graur and published by MIT Press. This book was released on 2022-02-08 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: A concise illustrated introduction to the history and physics of supernovae, the brilliant explosions of stars; with striking color illustrations. Supernovae are the explosions of stars. They are some of the most energetic phenomena in the Universe, rivaling the combined light of billions of stars. Supernovae have been studied for centuries, and they have also made appearances in popular culture: a glimpse of a supernova in a painting provides Sherlock Holmes with a crucial clue, for example. In this volume in the MIT Press Essential Knowledge series, astrophysicist Or Graur offers a concise and accessible introduction to these awe-inspiring astronomical phenomena. Graur explains that a deep observational understanding of supernovae—why and how they shine and how their brightness changes over time—allows us to use them as tools for experiments in astrophysics and physics. A certain type of supernova, for example, brightens and fades in such a predictable manner that we can measure the distances to their host galaxies. We owe our existence to supernovae—they give us iron for our blood and calcium for our bones. But supernovae may also have caused a mass extinction event on Earth 2.6 million years ago. Graur shows how observations of supernovae played a role in the transformation of astronomy from astrology to astrophysics; surveys the tools used to study supernovae today; and describes the lives and deaths of stars and the supernova remnants, neutron stars, and black holes they leave behind. Illustrations in both color and black and white, many from Graur’s own Hubble Space Telescope data, make this account of supernovae particularly vivid.
Download or read book Beyond Uranus written by Stewart Bruce and published by Stewart Bruce. This book was released on 2013-07-08 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beyond Uranus is the first of a trilogy of four or more books telling the ripping space yarns and illuminating times of an always late to work teacher and heroic on-line gamer. The wrong kind of life, in the wrong kind of job, leads Roy to emotionally subsist on lager, pizza and on-line gaming. A fantastical opportunity presents him with a chance to boldly go, where others have trod before. Joining the crew of a mysterious Earth Station, Roy becomes a space pilot working for the galactic ‘UN’ shielding the Earth from an inappropriate first contact. With a group of friends and an extraordinary personal computer he explores forbidden areas of the Station and excessively discovers that an alcohol ban doesn’t cover the whole of it. Meanwhile, rogue pilot Dr. John D’Eath has iniquitous plans to kill Roy but is thrown off the station when his plot to frame him for an attack backfires. And Roy finds the love of his life when he meets a beautiful red-head and loves the tinge of ginge in her. One day Roy attempts to shunt a mysterious freighter away from Earth and his indestructible ship is promptly destroyed, with himself being captured. Rescue comes from the person he least expects, which leads to him discover some shocking, hidden truths. Some 85,000 words help tell this humorous tale, peppered with bar-room philosophy and sprinkled with adult language.

Download or read book Silicon Nanophotonics written by Leonid Khriachtchev and published by CRC Press. This book was released on 2016-10-26 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photonics is a key technology of this century. The combination of photonics and silicon technology is of great importance because of the potentiality of coupling electronics and optical functions on a single chip. Many experimental and theoretical studies have been performed to understand and design the photonic properties of silicon nanocrystals. Generation of light in silicon is a challenging perspective in the field; however, the issue of light-emitting devices does not limit the activity in the field. Research is also focused on light modulators, optical waveguides and interconnectors, optical amplifiers, detectors, memory elements, photonic crystals, etc. A particularly important task of silicon nanostructures is to generate electrical energy from solar light. Understanding the optical properties of silicon-based materials is central in designing photonic components. It is not possible to control the optical properties of nanoparticles without fundamental information on their microscopic structure, which explains a large number of theoretical works on this subject. Many fundamental and practical problems should be solved in order to develop this technology. In addition to open fundamental questions, it is even more difficult to develop the known experimental results towards practical realization. However, the world market for silicon photonics is expected to be huge; thus, more research activity in the field of silicon nanophotonics is expected in the future. This book describes different aspects of silicon nanophotonics, from fundamental issues to practical devices. The second edition is essentially different from the book published in 2008. Eight chapters of the first edition are not included in the new book, because the recent progress on those topics has not been large enough. Instead, seven new chapters appear. The other eight chapters are essentially modified to describe recent achievements in the field.
