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...

Description
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...

Extrait : "Le milieu du dix-septième siècle fut une des périodes les plus glorieuses pour la pensée humaine. C'est alors que notre grand Descartes, réfugié en Hollande, publia son immortel Discours sur la méthode, qui forme, à proprement parler, la base de la philosophie moderne. À peu près à la même époque, un savant hollandais, nommé Swammerdam..."

A revolution is underway, and it's changing the way we illuminate the world. Light-emitting diodes (LEDs) are replacing conventional forms of lighting in everything from cars to billboards and from streetlights to desk lamps. Requiring less electricity than incandescent or fluorescent light bulbs, LEDs are the most efficient light source ever created. LEDs come in all the colors of the rainbow, but they are just about the greenest technology around....

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...

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...
