The Blackbirch Encyclopedia of Science & Invention Volume 4.

Acclaimed science writers Bryan Bunch and Jenny Tesar have created a wonderful 4-volume set that places every entry within the context of history. The lives and achievements of everyone from Aristotle to Vladimir Zworykin (inventor of the television camera and tube) are explained here, along with detailed entries on inventions and developments that changed the course of human history. Thematic discussions of broad topics -- such as airplanes, heat, and motion -- are presented in a format that clearly shows the development of each idea, and its connection to the work that came before and after.

This set includes:

• Highly cross-referenced entries for easy research
• Full-color icons indicate field of science for each entry
• "Connections timeline" element shows -- at a glance -- the progression of ideas that led to the development of each invention
• Special features-- such as Famous Firsts, How It Works, Nobel Prize profiles, and Yearbook -- add fun and interest
