In Marvels of Science, Isaac Asimov takes up a number of scientific topics of great interest and importance in our lives and brings them sharply and engagingly into focus. With his customary flair, he explains the chemical utilization of solar energy, our evolutionary kinship to the sea urchin, and the presence of radioactivity in the earth and in ourselves. He startles us with his discussions of the "unblind" workings of chance, comforts us with the abnormality of being normal, and tickles us with his spoofs of scientific reasoning. This incisive, informal, and witty sampler of some of the more intellectual aspects of science proves once again that Dr. Asimov is without equal as a medium between the seemingly inscrutable marvels of science and the inquisitive general reader.

ISAAC ASIMOV, associate professor of biochemistry at Boston University School of Medicine, has gained international distinction as both a science writer and a writer of science fiction.
