Chronicles the intellectual and technical discoveries that constitute the developments of refracting, reflecting, and radio telescopes, and related instruments, the personalities involved, and the astronomical knowledge gained by each advance

More of Isaac Asimov's weekly science columns for the Los Angeles Times and those his wife, Janet, wrote during his illness and after his death in April 1992. The Asimovs discuss how close we are to producing life in a lab, the latest revelations about dinosaur extinction, recent startling sightings of planets and stars, if we can establish colonies on Mars, if computer intelligence can ever surpass human intelligence, and the gravest dangers to our environment.

Frontiers probes the furthest boundaries of prehistory, science, earth space and the universe. It is a collection of short, topical and intriguing essays through which Isaac Asimov, the incomparable writer of science fiction, proposes brand new answers to classic scientific conundrums.

LIFE AND ENERGY is a brilliant introduction to the chemistry of life. In this highly lucid guide to the dynamics of modern biology, Isaac Asimov deftly explores the most recent discoveries in this constantly surprising field of inquiry. In the first part, he explains the mechanics of the inanimate world, the significance of energy, work, motion, heat, and chemical reaction. He then uses these concepts in the second half to analyze and explain the latest advances in the study of enzymes, amino acids, proteins and the very processes which constitute life itself. In short, Dr. Asimov's keen examination of biology's current desire to isolate and control the very basis of life--the significance of which promises to revolutionize life itself--becomes a fascinating as well as informative excursion. Illustrated with drawings, charts and diagrams.
