Editorial Reviews: Review Segrè spins a rousing tale of scientific thought and adventure. And like his subjects, he makes a convincing case for approaching new problems with a sense of wonder.–Publisher’s WeeklyAn exuberant dual biography that integrates developments in quantum physics, cosmology and genetics since the 1920s with the lives of these two scientists.–Kirkus ReviewsGino Segrè’s fascinating dual biography of George Gamow and Max Delbrück, “Ordinary Geniuses.” Gamow was a theoretical physicist who made an interesting foray into the biology of protein synthesis, while Delbrück was a theoretical physicist who became a biologist and then won the Nobel Prize for his work in genetics.–Wall Street JournalIn parallel chapters Segrè has sensitively and insightfully narrated chronologically Delbrück and Gamow’s personal and professional lives. And while doing so, he has clearly presented and explained their scientific contributions; the prior works on which they were based; and their present day importance and relevance.–American ScientistSegrè convincingly shows how the pair’s maverick personalities led to their discoveries, while their restlessness often stopped them seeing their ideas to maturity.–New Scientist“Ordinary Geniuses makes me wistfully wonder if the world will ever again witness the coming together of such fun-loving intellectual brilliance.”—James D. Watson, author of The Double Helix “George Gamow and Max Delbrück were free spirits and practical jokers. They broke away from the mainstream of science in the 1930s and found new ways of thinking that opened the way to new sciences in the 1950s. George invented Big Bang cosmology, and Max invented molecular biology. This book brings them magnificently to life. It gives us a fresh view of the way new sciences are born.”—Dr. Freeman Dyson, Princeton Institute for Advanced Study “Ordinary Geniuses is no ordinary book. Gino Segrè, a masterly storyteller, takes us off the beaten path to view two revolutions in twentieth-century science from a novel perspective. By chronicling the lives of two renegade scientists, Max Delbrück and George Gamow, Segrè puts the birth of both molecular biology and modern cosmology in a whole new light. An engaging read.”—Marcia Bartusiak, author of The Day We Found the Universe “Gino Segrè is an accomplished scientist, a gifted writer, and a meticulous scholar. His talents come together in this wonderful book, the story of the intertwining careers of two quite amazing scientists. But it is more. It is a loving ode to twentieth-century science and will enthrall as it instructs.”—Kenneth W. Ford, author of 101 Quantum Questions: What You Need to Know About the World You Can’t See; former director, American Institute of Physics “A marvelous book. Segre describes vividly how Delbruck helped to establish the new science of molecular biology while Gamow went into cosmology and originated our current view of the Big Bang. They both left major impressions on science as might be expected from “ordinary geniuses.””—Alex Rich, Sedgwick Professor of Biophysics at M.I.T. About the Author Gino Segre is the author of A Matter of Degrees and Faust in Copenhagen. An internationally renowned expert in high-energy elementary particle theoretical physics, he is a professor emeritus of physics and astronomy at the University of Pennsylvania.

⭐The mathematician Mark Kac classified geniuses into two kinds. “Ordinary” geniuses were those who accomplished a lot, but who gave you the feeling that you too could be as successful if you worked hard enough. The other kind of genius was the “magician”, a person whose thought processes for all intents and purposes were hidden from you and who made you feel that you could not catch up no matter how hard you tried.Kac’s distinction does apply, but it’s also a little unfair to “ordinary” geniuses who happen to include many Nobel laureates. These ordinary geniuses may not have been Newton, Darwin or Einstein but collectively they were responsible for the underpinnings of most of modern science. In this book the physicist and author Gino Segre brings two such ordinary geniuses- George Gamow and Max Delbruck- to life. Gamow and Delbruck are not as famous in the public eye as some of their contemporaries like Einstein, Dirac or Feynman but as Segre marvelously demonstrates, they were founding fathers of two of the twentieth and twenty-first century’s most important fields- cosmology and molecular biology. Segre does a great job of explaining the two men’s discoveries, lives and working philosophies and also paints a vivid portrait of the important times which they lived in.Both started as physicists, Gamow in Russia and Delbruck in Germany. Both grew up amidst war and civil strife and ended up emigrating to the United States as refugees from communism and fascism; Gamow had to literally flee from the Soviet Union to escape Stalin’s yoke. Both were lucky to grow up during the heyday of modern physics when quantum mechanics was being created in Germany, England and Denmark. Gamow made an early name for himself by pioneering nuclear physics while Delbruck floundered as a physicist for some time before finding his niche in biology. The two met in Niels Bohr’s famous institute in Copenhagen where they discovered their common interests and struck up a lifelong friendship.One of the biggest virtues of the book is in bringing out the distinctive working style of the two scientists. This style was marked by independence of thought, an unwillingness to follow the beaten track and a relentless enthusiasm for staking out new grounds. Both men were mavericks who, in Gamow’s words, were always looking for the next “pioneering thing”. Inspired by Bohr, Delbruck turned to molecular biology when the subject did not even formally exist. Thinking of a basic experimental unit in biology akin to the hydrogen atom in physics which would shed light on key biological processes and be amenable to experiment, Delbruck picked bacteriophages- viruses which attack bacteria. Along with another emigre, the Italian Salvador Luria, he performed foundational experiments that demonstrated the fundamental role of mutations and their effect on bacterial phenotypes. With a few elegant studies Delbruck and Luria connected genetics to bacteriology. Since then microbial genetics has been the source of some of our most important insights into heredity, genetic engineering and medicine. The phages whose importance they highlighted continue to be tools of incredible utility in our search for genetic mechanisms and new medical therapies. Along with Alfred Hershey, Delbruck and Luria were awarded the Nobel Prize for their work in 1969.While Delbruck was tinkering with viruses, Gamow turned to nuclear and astrophysics when the fields were not too popular. He was the first to explain the so-called bizarre “tunnel effect” in alpha decay, a quintessentially quantum mechanical phenomenon which allows particles to surmount energy barriers which are classically unsurmountable. The tunnel effect underlies many important processes in physics and chemistry, from nuclear decay to the workings of enzymes. But Gamow’s main contribution was in formulating the Big Bang Theory which is at the foundation of modern cosmology. He thought longer and harder about the origin of the universe than most of his contemporaries and he did this long before the physicists Arno Penzias and Robert Wilson discovered the cosmic microwave background radiation emanating from the Big Bang, which Gamow had actually predicted. It is a pity that Gamow did not share the Nobel Prize with them.Later in life, Gamow became a world-renowned popularizer of science. His popular physics books inspired many children to study science and his “Mr. Tompkins” series brought the bizarre mysteries of quantum mechanics to the masses. I myself remember being greatly inspired as a child by the wit and insight in these volumes. As if these contributions were not enough, Gamow later turned to molecular biology and collaborated with the founders of molecular biology including James Watson and Francis Crick. He supplied some of the early thinking about the genetic code and even though the details of his ideas were not correct, he stimulated others to think in the right direction. Delbruck himself was inspired by Gamow’s ideas. In his later life he became a mentor to a whole generation of biologists, mostly at Caltech and at Cold Spring Harbor Laboratory, who founded the study of genomics. Delbruck contributed as much through his mentorship as through his research.In addition as the book showcases, the two were eminently interesting characters. Delbruck was a man who spoke his mind, not afraid to poke, probe and question until he got to the truth. Gamow’s colorful personality has become the stuff of legend. He was a practical joker who used to constantly play pranks on his colleagues and insert jokes even in technical scientific papers. Just one anecdote will suffice; in a bar, some of Gamow’s friends once bribed a waitress to startle him by asking him if he was the British physicist Fred Hoyle, the Big Bang Theory’s staunchest opponent. Without missing a beat Gamow replied, “Now now, don’t throw Hoyle over troubled waters.”Gamow and Delbruck showed us not just how to do great science but how to have fun doing it.Max Delbruck’s and George Gamow’s ideas essentially underlie some of today’s most important questions in biology and cosmology. For all of Kac’s categorization of geniuses, there is no doubt that the two were extraordinary scientists. We will all continue to stand on their shoulders.

⭐”Ordinary Geniuses” by Gino Segrè”Ordinary Geniuses” pleasantly relates the historical intertwining of Physics and Biology from the 1930’s to the 1960’s through the lives of George Gamow and Max Delbrück.George Gamow (1904 – 1968) discovered radioactive decay in which an atomic nucleus emits an alpha particle and worked on star formation, “Big Bang” cosmology, creation of chemical elements from hydrogen, cosmic microwave background, and genetics. Max Delbrück (1906 – 1981) studied astrophysics moving to biology studying genetics, bacteria and their viruses or `phage’, and won the Nobel Prize in Physiology or Medicine in 1969 for the replication mechanism and genetic structure of viruses.This dual focus allows a comparison of the development of the new fields of `Big Bang’ cosmology and molecular biology. Yet there are two quibbles.Is the “Ordinary” qualification to “Geniuses” necessary or deserved? These days, the term “genius” seems to be well defined in James Gleick’s book on Richard Feynman titled “Genius”. (“There are two kinds of geniuses, the `ordinary’ and the `magicians’. An ordinary genius is a person that you and I would be just as good as, if we were only many times better. There is no mystery about how their mind works. Once we understand what they have done, we feel certain that we, too, could have done it. It is different with the magicians … where … the working of their minds is for all intents and purposes incomprehensible. Even after we understand what they have done, the process by which they have done it is completely dark.”) But is the stratification of “Genius” v’s “Ordinary Genius” warranted in this book? Not really.Secondly, the lives of these two scientists did intertwine to an extent and there were common traits such as their maverick approach breaking away from the mainstream. Yet does the switching from Physics to Biology and back burden the story, particularly when combined with the necessary personal and historical context plus associated anecdotes? [Incidentally, a good anecdote is that about Wolfgang Pauli “… you never had to worry about asking him a stupid question because he regarded all questions as stupid”. And of course the famous ‘alpha/beta/gamma’ paper where Hans Bethe was added as second author to a paper by Ralph Alpher and George Gamow simply for effect; and even an attempt to get Bob Herman to change his name to Delter to get the foursome ‘alpha/beta/gamma/delta’.]These quibbles aside, the story of both maverick scientists George Gamow and Max Delbrück gives rare insights into two major revolutions of twentieth century science from an historical viewpoint and the personal view of grasping the power of intellectual freedom. Both scientists founded entirely new areas of the highest intellectual achievement. Achievement only restrained by the false assumptions that the origin of the universe and the origin of life on earth were beyond the bounds of science [e.g. “… scientists in the 1950’s felt `uncomfortable’ talking about anything as remote as the universes first minutes” so they did not look for the microwave background radiation, delaying its discovery for a decade; and similar delays to appreciate that DNA is the carrier of genetic information].Perhaps the next step is to search for further reading of these two geniuses, either together as presented by Gino Segrè or just the reader’s favorite. After all, thanks in a large part to them, today we understand the ramifications of the Big Bang and have mapped the human genome.Malcolm Cameron13 September 2011
