THE IMPOSSIBLE MAN

One of the greatest physicists and mathematicians of the past century receives his first biography.

Science journalist Barss, author of Flow Spin Flow: Looking for Patterns in Nature, does a fine job with a difficult subject. Penrose, now 93, did not win his Nobel Prize until 2020. Few deny his genius, but explanations of his groundbreaking discoveries are, like Stephen Hawking’s, likely to baffle a lay audience and were no snap for his colleagues. His Ph.D. advisors, world-class mathematicians, acclaimed his thesis but found it “by no means light reading.” Einstein’s relativity, which illuminated space, time, and gravity, is easier to explain. Penrose discovered the limitations of relativity but also simplified many of its complex equations. Ironically for a mathematician, Penrose disliked equations, preferring to view the cosmos visually. This fascination with geometry has made his name best known for a few dazzling optical illusions such as the Penrose triangle and Penrose staircase. Penrose’s genius was no secret. He was showered with honors, lectured, traveled the world, and enjoyed collaboration and quarrels with fellow scientists. His personal life was less satisfactory, although Barss has a much easier time explaining it. His brilliant but distant father encouraged a fascination with science and puzzles but seems to have left his son emotionally challenged. A popular speaker, Penrose had no trouble dealing with fellow scientists but seemed unable to handle intimate relationships. Intensely attracted to energetic, accomplished women, often fellow mathematicians, he married two but carried on long relationships with others whom he openly referred to as his “muses,” preferring to pepper them with his papers and solicit feedback, behavior they found both flattering and creepy. Readers may incline toward creepy.

Superb insights into a flawed genius.
