Books (Concluded from page 62) Have You Seen These? RECENT BOOKS likely to be of especial interest to M.I.T. Alumni include: Arms Control, Disarmament, and National Security, edited by Donald G. Brennan, '55, with the sponsorship of the American Academy of Arts and Sciences (Braziller, $6). The Collected Works of Irvin Langmuir, with an Honorary Editorial Advisory Board including William D. Coolidge, '96, and Horace R. Byers, '32 (Pergamon Press, 12 volumes, $150). The Future Metropolis, edited by Professor Lloyd Rodwin of M.I.T., with contributions by Professors Gyorgy Kepes, Kevin A. Lynch, '47, Martin Meyerson, and others (Braziller, $5). A History of Metallography, by Cyril Stanley Smith, '26, newly appointed Institute Professor at M.I.T. (University of Chicago Press, $8.50). Miniaturization, edited by H. D. Gilbert, with a concluding chapter, "There's Plenty of Room at the Bottom," by Richard P. Feynman, '39-an article that attracted great attention when published in the May, 1960, issue of The Technology Review-(Reinhold, $10). Plasmas and Controlled Fusion, by David J. Rose, '50, Professor of Nuclear Engineering, and Melville Clark, Jr., '43, Associate Professor of Nuclear Engineering (The M.I.T. Press and John Wiley & Sons, Inc., $10.75). MAN'S VIEW OF THE UNIVERSE, by R.A. Lyttleton; Atlantic-Little, Brown ($3.95). Reviewed by Martin Mann, '41, Senior Editor, Popular Science Monthly, and author of several science books for laymen. This little book is a collection of concise, encyclopedia-like chapters. You can breeze though it in an evening and collect the high points of modern knowledge of the heavenly bodies. Or you can browse for material that is new or intriguing–the chapters are independent enough to be enjoyed whether you have read the previous pages or not. The organization is logical. Lyttleton starts with the earth, describing its structure and the way it may have been created. He then duplicates this formula as he moves out from the earth to the moon, planets, sun, comets, stars, galaxies, and entire universe. The two chapters on comets may be the most interesting. Not many readers will realize that there are more of them than of any other celestial object in the universe (250,000 comets for every star). There is also plenty of "gee-whiz": the incomprehensible vastness of space (light, traveling six million million miles in a year requires four and a half years to reach us from the star nearest to the sun), and the equally incomprehensible emptiness of space (a dense cloud of interstellar gas contains 1,000 hydrogen atoms per cubic centimeter, a density of 10^-21 grams per cc.). While brevity is to be applauded–this book is a paragon of that virtue–it does have drawbacks. Detail is severely limited. The drawings are apt and useful, the photographs beautiful but routine.

[[/captions]] You'll save up to 66% in original bit costs, more than 33% in replacement costs, and get more footage, too, with "WYR-LOK" carbide-tipped core bits. Tests prove them far more efficient than conventional diamond core bits – and YOU CAN DRILL DRY. Cutting heads are replaceable without removing bit from machine. Easy to sharpen on the job. Available in standard lengths. From 2" to 6" in diameter; larger diameters on request. DRILL FASTER! COST LESS! CONDECO PORTABLE DRILLING MACHINES ONE-MAN OPERATED! FOR WET OR DRY DUSTLESS CONCRETE DRILLING! Condeco Drilling Machines are rugged, powerful units that will easily drill through any type masonry including reinforced concrete. Designed and Engineered for use with "WYR-LOK" Bits, they will save you time and money on every drilling job. Available in several models for horizontal or vertical drilling of holes from 2" to 14" diameter. Drilling is done dry using vacuum or wet. Easily portable to the job – they are one man operated.
