THE RIDDLE OF TIME

The authors! explanation of this difficult scientific and philosophical concept is smoothly written, and appears to be unusually thorough. But, there is too much tangential information presented, which- while it adds to the conversational flow- often ends in disorganized rambling, causing ornate obscurity to reign in place of plain clarity. Although two comparatively untouched topics- geological time and biological time- are covered, this study does not serve as a replacement for either Tannenbaum's Understanding Time (1958, p.608, J-194) or Zarchy's Wheel of Time (1957, p.776, J-286), two fine studies of this subject for young scientists.
