Written by one of the pioneers in visual perception, Seeing provides an overview of the basics of sight, from the anatomy of the eye, to optical illusions, to the way neural systems process visual signs. To help readers better appreciate the most-used of our five senses, Tom Cornsweet describes the early physical and physiological processes that occur in human vision in relation to the forces of evolution. He also includes answers to commonly asked questions about vision-including those that many of us ask during a visit to an eye doctor-to illustrate how the study of vision can provide a better understanding of one's everyday relationship with sight.

Have you ever wondered why some objects float, why the sky is blue, or why some people are color blind? Or perhaps you want to understand the nature of light, gravity, and waves.

You are not alone. There are lots of young people just like you who wonder about these things every day and are craving answers.

Among them are Nicky and Pat, two friends who engage in an in-depth conversation as they seek to answer their questions about science. Along the way, they are helped by DeM, their omniscient guide who helps them unravel the scientific mysteries they can't figure out themselves.

Join Nicky and Pat and satisfy your own curiosity as you learn about: Vision and images Basic phenomena such as resonance, diffraction, and refraction How eye glasses work and other answers to your practical questions And much more Learn how to make guesses, test your theories, and examine the world more closely. Log on to the Internet and download free programs that will help in your quest. It all starts with asking the right questions in Why is Everything
