What should you know about science? Because science is so central to life in the 21st century, science educators believe that it is essential that everyone understand the basic foundations of the most vital and far-reaching disciplines. "Science 101" does exactly that - it provides readers of all abilities with an accessible summary of the ideas, people, and impact of major fields of scientific research. The volumes in the series provide readers - whether students new to the science or just interested members of the lay public - with the essentials of a science using a minimum of jargon and mathematics. In each volume, more complicated ideas build on simpler ones, and concepts are discussed in short, concise segments that make them more easily understood.
