Description: Challenge of the Universe:A Joint Project of the National Science Teachers Administration(A Vistas of Science Book)MYSTERIOUS LIGHTS OVER PHOENIXBy J. Allen Hynek Paperback: 143 Pages — Publisher: McGraw-Hill (1963) From the back cover: "Challenge of the Universe is a fascinating casebook of astrophysics and celestial mechanics - of facts, theories, and speculations. In it, you will discover how astronomers determine the dimensions, masses, even the ages and physical conditions of stars. There is even a scheme for air-conditioning Venus. A dream? Yes - but progress is built of dreams. And, there is more. A chapter on relativity, complete with the elegant algebra of Einstein, shows why man is forever limited to one infinitesimal sector of the universe. At the end of the book you will find a section of projects and experiments - many of them - all challenging, fun, and inexpensive." Condition: VERY GOOD. Used - Very Good.
