229 pages; Near Fine/No Jacket. Tee-niny bit of shelf rub at spine tip and bottom corner tips. Boards are straight, tips are pointed, spine is square and pages are clean. An excellent gift! I have written this book in response to numerous suggestions and much encouragement from my friends. It was only after I had made various promises to them that I discovered how easy it was to write about science for specialists and how difficult it is to explain its findings to others, even to scientists outside one's own discipline. Several photos of our planets, and pictures from Voyager 2.
