Examines a study of the sky, where rainbows form and many other unique facts about them

Renowned science author Vicki Cobb illuminates the scientific principles of light and reflection in a way that even the youngest kids can understand

"Delving into mythology, religion, philosophy, painting, and science, 'Light' captures the wonder and awe of humanity's study of light across three millennia of discovery"--Front jacket flap

"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"--

One day, down by the pond, Simon meets another dog just like him. And that dog has a bone just like his, only better! How will Simon ever get him to trade, when the other pup knows all the same tricks? Using the same innovative format as his Caldecott Honor winner, Mel Fell, Corey R. Tabor reimagines Aesop's "The Dog and His Reflection" in a clever, charming tale of empathy and generosity

This accessible reference book introduces the fundamentals of optics, revealing key concepts through engaging examples. It covers the behavior of light, including reflection, refraction, and diffraction. You'll learn how lenses and mirrors form images, how the eye sees, and the workings of common optical instruments. You'll also explore...

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....

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...
