'X' Stands for Unknown – Isaac Asimov - 3 stars

[Linda C]

The 17 essays in this collection were originally printed in The Magazine of Fantasy and Science Fiction. They cover topics in physics, chemistry, astronomy and mathematics. The ending essays deal with the state of science in education and religion. For the most part they covered the major developments and discoveries in these fields from their beginnings to the early 80s and are the basis for technology today. Interesting and informative.
