Query: Great book

This is a really good book. Lewis explores the physics and chemistry of the worlds in our solar system, and then using the principles of physics and chemistry learned there to explore the possibilities of other worlds, and life on them.He presents several mind-bending -- yet scientifically feasible -- worlds for our consideration. "Earthissimo," for example, made me put the book down, lean back in my chair, and SAVOR the elegance of the science for several minutes. Wonderful!BUT, like Lewis's otherwise excellent _Mining the Sky_, he doesn't include any graphs, table or illustrations. (He has a few artistic rendering in the middle, which are different.)A few graphs or tables would have clarified his arguments and saved pages of dense, descriptive text.Good book, mind-twisting science, poor presentation: 4 stars.
