How much do you know about the radiation all around you? Your electronic devices swarm with it; the sun bathes you in it. It's zooming at you from cell towers, microwave ovens, CT scans, mammogram machines, nuclear power plants, deep space, even the walls of your basement. You cannot see, hear, smell or feel it, but there is never a single second when it is not flying through your body. Too much of it will kill you, but without it you wouldn't live...

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...

"Sunrises and lightning storms, rainbows and volcanoes, meteors and fireflies-these beautiful, and sometimes frightening, events that light up the sky might seem like magic. But there is a scientific explanation for each natural phenomenon. Find out the science behind the magic in this beautiful and enlightening nonfiction picture book"--

Some efforts have been made to prove negative mass behavior through some experiments performed in mechanics, and other disciplines as well as some theories in electrostatics, but I haven't found research about similar effects at the atomic level, where the most elementary mass given by the atomic nucleus is to be found.Is the second Newton's law still valid with negative mass?What could happen if we make the atom behave in a negative mass regime?Is...

Looks at the history of the study of light and optics and presents science experiments and projects that demonstrate these principles.

The following topics are presented in this book: dielectric waveguides, flat plate, and guided propagation acousto-optic and electro-optical modulators optical amplifiers optical gratings lasers

One of the first texts to offer a simple presentation of the theoretical foundations of steady-state laser spectroscopy, this volume is geared toward beginning theorists and experimentalists. It assists students in applying theoretical ideas to actual calculations in laser spectroscopy with a systematic series of examples and exercises. Starting at an elementary level, students gradually build up their practical skills with demonstrations of how simplified...

As the words holo (complete) and gram (message) connote, the hologram captures the entire message of a scene in all its visual properties, including the realism of three dimensions. It involves the simple process of photographically recording the pattern formed by two interfering sets of light waves, one of these sets being a reference wave. With the introduction of lasers to holography in 1963, real advances in the development of holography began...

This invaluable practical guide shows how to set up working models of telescopes, microscopes, photographic lenses and projecting systems, then shows how to conduct experiments for determining accuracy, resolving power, identifying aberration, and more. Only elementary mathematics required. Index. 234 diagrams.

Lasers play an increasingly important role in a variety of detection techniques, making inelastic light scattering a tool of growing value in the investigation of dynamic and structural problems in chemistry, biology, and physics. Until the initial publication of this work, however, no monograph treated the principles behind current developments in the field.This volume presents a comprehensive introduction to the principles underlying laser light...
