This text provides an overview of the history of virtual reality and explores the tools and techniques used to mimic the physical world, the fields in which virtual reality is being used, and some of the obstacles that supporters of virtual reality have had to overcome.

Some of the most significant and potentially devastating dangers to human and animal life come from sources we cannot see without the help of microscopes. Viruses, bacteria, and other microorganisms have been a troubling presence in the world probably from the time multicellular life first appeared. As part of the new Science and Technology in Focus series, Biohazards covers the history of how these extremely powerful microscopic invaders have plagued the human race and how humans have responded to these attacks. Comprehensive and up-to-date, this volume looks at the recent resurgence of...

The energy of light carries much of the world's information from one place to another.

Optics is one of the...
