Isabel and the invisible world

"There's only one gift Isabel wants for her sixth birthday: a way to see invisible things. She can hardly think of anything else! Finally, the day of her party arrives. Unwrapping a big box, Isabel finds a surprise inside--a glass prism--and a dazzling world of previously invisible color emerges, lighting up the room around her. What else could be out there, waiting for her eyes to discover? . . . Author and physicist Alan Lightman unveils the hidden world of light waves--the ones you can see and the ones you can't"--Provided by publisher.
