Books with author P. Andrew Karam Ph.d.

The universe contains just two things: matter and energy. Matter makes up almost everything imaginable: furniture, food, houses, rocks, living organism, and the whole Earth. Energy is not as easy to see, but it powers race cars, makes living things move, and travels distances ranging from the confines of an atom to the ends of the universe. In Matter and Energy, readers will learn about the many forms of energy, the wide variety of particles in nature, and Albert Einstein's world-changing realization of how matter can be changed into pure energy. The book also examines the recent discoveries of dark matter and dark energy and the future of the universe.

Our world is largely defined by what we see and hear, but our uses for light and sound go far beyond simply seeing a photo or hearing a song. Lasers, concentrated beams of light, are powerful tools used in industry, research, and medicine, as well as in everyday electronics like DVD and CD players. Ultrasound, sound emitted at a high frequency, helps create images of a developing baby, cleans teeth, and much more. Light and Sound teaches how light and sound work, how they are used in our day-to-day lives, and how they can be used to learn about the universe at large.
