Summing up: RECOMMENDED. Upper division undergraduates through professionals; technical program students." U. Greife, Colorado School of Mines, USA "I found the biographical accounts of the various stalwarts of Physics inspirational. Most of them, if not all, had to overcome economic hardships or p[ersonal tragedies or had to do their groundbreaking work in the face of tyranny and war. The biographies also highlighted the high standards of moral convictions that the scientists had as they realized the grave implications of some of their work and the potential threats to humanity. This ought to inspire and motivate young men and women aspiring to be physicists. Even people who have been in the field for a while should find your book re-energizing. It certainly had that effect on me." -- Dr. Ramkumar Venkataraman, Canberra Industries, Inc., Meriden, CT, USA Winner of an Honorable Mention in the 2017 PROSE Awards in the category of Chemistry and Physics (https://proseawards.com/winners/2017-award-winners/ )
