Winter Reading 2019 A Ray of Light: A Book of Science and Wonder


If you have read A Drop of Water and wished for more books like it from Walter Wick, your wait is over. With the same painstaking care, he has created an excellent book that explains light. Everything from energy, incandescence, waves, the color spectrum...practically every topic within the study of light is discussed. 

The explanations are easy to understand and the photographs clearly illustrate the concepts. For instance, there is a full page image of a prism splitting white light into the visible spectrum, then a closeup of the spectrum is shown beneath the text. A pair of photos show color wheels at rest, and then the same wheels spinning so that all the colors blend together into a dull gray.

There are also several pages on how a lens can intensify light, or be used in telescopes and microscopes to magnify the appearance of objects. Sunlight, spectroscopic analysis of distant stars, pigments, colors in nature - Wick covers so many concepts that it is hard to believe it all fits within so few pages. And the back matter explains the experiments shown in the photos in more details, as well as how the photos were made.

This book is a must for science classrooms and school library collections.

I read an ARC provided by the publisher for review purposes.
