This book will serve a useful purpose for the science-minded reader interested in bringing his information on contemporary developments up to date. The author -- well known as science editor of the New York Herald-Tribune and Pulitzer Prize winner for science journalism, has done a sound job of selection in timely (and occasionally still unsolved) problems in the biological fields of zoology, anthropology, genetics, physiology, psychology, and in the physical science areas of meteorology, geology, mathematics, engineering, astronomy, and chemistry. Important developments of the last ten years are viewed in each field. Both format and style will attract the general reader, but the actual text content demands a sound science background. One assumes that adequate cross indexing will make this a useful reference book for the scientific reader. A pleasant journalistic style combined with scientific accuracy make it recommended for reading interest and value.
