The world's flora...

An introduction to light and how it helps us to see profiles different kinds of light, including sunlight, firelight and electric light, and provides interactive experiments readers can perform at school or at home.

Describes how scientists investigate the physical phenomenon of light.

An introduction to the sources and characteristics of light.

Starting with Einstein's theory of relativity, Physics of light explores the true nature of light, peers inside the atom, and looks ahead to the most cutting edge theories in physics. The six-part series uses the medium of light to explore the concepts of physics from familiar theories, such as Newton's law of gravity, to the latest in scientific research, like string theory and M-theory.

Using real-world demonstrations and colorful graphics, this program teaches students the different properties of light, pertinent definitions and how light travels. Students will learn how different mediums can affect light resulting in reflection, refraction and absorption, and they will explore the color spectrum using prisms and paints.

A guide to house plants that will thrive in shady conditions.
