Half-Life

The Book of the Week is “Half-Life, The Divided Life of Bruno Pontecorvo, Physicist or Spy” by Frank Close, published in 2015. The author himself was a physicist, so he interspersed physics concepts with the evolution of the development of nuclear technology and its major players. This book was written for readers who would like to learn some nuclear physics, and/or those readers curious about the people involved in Cold War / nuclear physics mysteries.

However, Close made an error, spelling “Lise Meitner” as “Lisa Meitner.” Additionally, since the author was neither a historian nor American (he was British) he was mistaken in declaring, “For supporters of communism in the West, this [the autumn 1956 Hungarian uprising which was bloodily crushed by the Soviets] was probably the most serious crisis of conscience since the Soviet pact with the Nazis in 1939.” Actually, in early 1956, Khrushchev revealed Stalin’s horrific crimes to the world. Americans, especially those who considered themselves Social Democrats, were thrown for a loop ideologically, and became bitterly conflicted in their own minds, and with each other.

Anyway, born in Italy in August 1913, Pontecorvo was the fourth of eight children. In 1931, he transferred from the University of Pisa to that of Rome for his third year of physics studies, mentored by Enrico Fermi. Knowledge of particle physics was in its infancy. Pontecorvo and other scientists jointly filed a patent in autumn 1935 in connection with experiments with neutrons and hydrogen.

The year 1936 saw Pontecorvo flee to Paris after Mussolini cracked down on Jews’ liberty. He studied with Frederic and Irene Joliot-Curie. He was turned on to Communist ideology by his cousin. They attended meetings and rallies.

By the late 1930’s, physicists (and governments) of different nations such as Germany, France, Italy, the USSR, etc. started to realize how important nuclear processes were for creating future weapons of mass destruction– instrumental for their respective homelands’ national security. Beginning in the summer of 1940, nuclear research became secret in the United States. Scientific journals would no longer publish articles on that topic.

The USSR did not lack for brains, but for uranium in the early 1940’s. Beginning in summer 1942 in Moscow, the Soviets worked on an atomic bomb. But scientists in the United Kingdom had a head start, having begun their work the previous year. In December 1942, the United States started the Manhattan Project.

By the end of the 1940’s, having done nuclear research in Tulsa in Oklahoma, the Northwest Territories in Canada and in Harwell in England, Pontecorvo was planning to move himself, his wife and three sons to Liverpool to become a physics professor. The British intelligence service MI5 secretly pushed him in that direction. As is well known, the United States was gripped by anti-Communist hysteria, with the arrests of spies Klaus Fuchs, David Greenglass and the Rosenbergs.

The summer of 1950 saw the Pontecorvo family take a summer vacation in France, Switzerland, and the Italian countryside. There is circumstantial evidence that he met with his Communist cousin and suddenly, all bets were off.

Read the book to learn the fate of the family, the contributions made to science by the scientist, learn why he neither won the Nobel Prize nor collected royalties on the aforementioned patent, and much more.

The Last Man Who Knew Everything

The Book of the Week is “The Last Man Who Knew Everything, The Life and Times of Enrico Fermi, Father of the Atomic Age” by David N. Schwartz, published in 2017.

Born to a wealthy family in September 1901 in Italy, Fermi was mentored in science by a colleague of his father, who worked for the railroad. This, after suffering the trauma of having his older brother die unexpectedly having throat surgery in 1914.

Fermi had a photographic memory, which helped to make him a brilliant student in mathematics and physics from studying textbooks. He was required to learn German too, to keep abreast of developments in the scholarly journals.

Fermi eventually became a physics professor at the University of Rome. His teaching gig, which he was also really good at, lasted from 1926 to 1938. He married in July 1927 and several years later, he wrote, and his wife edited and translated, a high school physics textbook that became part of the standard high school curriculum in Italy.

Quantum statistical mechanics was his specialty. Athleticism was another. Fiercely competitive, he always outdid his colleagues in hiking and climbing the hills around Rome. He became well traveled, thanks to attendance at international physics conferences. Some were hosted in the United States, which had better research funding than his native country.

By the late 1920’s, Fermi had cofounded a world-class nuclear physics research institute in Rome. The first entering class consisted of three graduate students. The younger generation was reflecting on new quantum theories to which the old-school Italian physicists were resistant. Fermi was in the former group.

In spring 1929, Mussolini selected members, of which Fermi was one, for an elite scientific society. He offered them big money so that they would do Italy proud (like academic and athletic scholarships bestowed upon fiercely competitive students, dispensed by elitist schools in the United States nowadays).

In the early 1930’s, Fermi supervised scientists who traveled internationally to different labs to learn from their fellow Europeans; yet they also competed with physicists at prestigious institutions in Berlin, Paris, Berkeley in California, and Cambridge in England.

In October 1934, Fermi’s team discovered that “…slowing down neutrons enhanced the radioactivity induced by neutron bombardment.” In connection therewith, he applied for a patent in Italy and the United States. He got a new lab.

By 1936, Mussolini was finding that invading Ethiopia was an expensive proposition. He began to depend on financial aid from Nazi Germany. By summer 1938, Hitler had control over ruining careers of Jews in licensed professions, civil servants, and white collar jobs in Italy.

In late 1938, after much red tape and worrisome scheming, Fermi and his wife (who had been deemed Jewish) escaped Italy first for the Nobel Prize ceremony in Stockholm, at which he took his trophy and money, and then for the United States. He ended up working at Columbia University.

At a Washington, D.C. conference in January 1939, physicists announced they had figured out how to produce fission, the process required to detonate an atomic bomb. Some were concerned that if Hitler’s scientists got hold of such knowledge, he would order mass destruction of his enemies before they could stop him. Fermi felt there was a low probability that Germany could build such a device. But Fermi was persuaded to share the thereafter-secret formula with the United States Navy. This would show his loyalty to America at a time when Italy was not exactly America’s ally.

Read the book to learn the parties involved with, locations of, trials and tribulations regarding, and Fermi’s role in the Manhattan Project; what Fermi did thereafter; and the Edward Teller/J. Robert Oppenheimer dispute, plus other physics-related occurrences up until Fermi’s death.

Von Braun

The Book of the Week is “Von Braun, Dreamer of Space, Engineer of War” by Michael J. Neufeld, published in 2007.

Born in Prussia in March 1912, Wernher von Braun grew up in a wealthy, cultured, intellectual family who encouraged his interest in science. He played the cello and piano. At thirteen years old, he was sent to boarding school. Although he failed math and physics, he learned these subjects to the extent he needed to in pursuing his passion for rocketry and astronomy.

In 1932, von Braun’s father snagged a plum civil service position. As a result, the German army funded von Braun’s research into rocket-based weaponry. In summer 1933, he took flying lessons. He later completed his PhD at one of the most prestigious universities in Germany.

After Hitler’s purge of political dissidents in spring 1934, the German army and air force had a duopoly on top-secret ballistic missile research directed and supervised by von Braun.

In November 1937, von Braun was compelled to join the Nazi party, or be fired. Although ample evidence has emerged that he was aware of the evil purposes to which his projects were applied, he appeared to suppress his moral revulsion in connection therewith. His first love and loyalty was working toward his goal of creating vehicles that could explore outer space. But he was ordered to make weaponry first.

“After 1938, corporate and university researchers were also integrated in increasing numbers, further propelling funding in breakthroughs in liquid fuel propulsion, supersonic aerodynamics, and guidance control.” In spring 1940, von Braun was compelled to join the SS or be fired. He reluctantly did so.

Von Braun’s was a serious moral dilemma. It is unclear what the consequences would have been had he refused to willingly participate in operations involving slave labor (Resistance fighters, Communists, criminals, concentration camp internees) subjected to inhumane conditions (disease, torture, starvation) in making the instruments of war, and to willingly participate in the making itself.

The first successful ballistic missile (launched via a rocket), occurred in October 1942, after various trial-and-error failures (balls-of-fire explosions). This kind of experimentation at that time was, and still is, agonizingly slow and astronomically expensive. At the start of WWII, the weapons program had about twelve hundred employees. Wartime meant von Braun’s experimental resources of nitric acid, diesel oil and aluminum alloys were diverted to Hitler’s actual military usage, causing serious production problems.

In spring 1945, von Braun and his immediate boss were able to carry out their plan at war’s end of turning themselves over to the Americans, with whom they would share their rocketry expertise.

According to the author, in June 1945, the Americans liberating Germany persuaded about 350 skilled rocket-workers, and their relatives, numbering a few thousand, to emigrate to Alabama and New Mexico in the United States. The Soviets grabbed a few “brains” who traveled to East Germany, and then the Soviet Union. The author didn’t explicitly state which superpower acquired more talent.

In the 1950’s in the United States, von Braun published his writings, lectured, and literally broadcasted his opinion that the United States should engage in space exploration for the purpose of launching a satellite that would indicate weapons installations of surveilled regions on earth, among other purposes.

Read the book to learn of the political power struggles and trials and tribulations that von Braun and the German and U.S. governments underwent in aerospace research as matters of national pride and security; of why some historians might describe von Braun as an overrated attention whore; and how times have changed (hint– in the 1960’s, “…only nation-states had the resources to finance and direct huge guided-missile and space programs.”).

The Pioneering Odyssey of Freeman Dyson

The Book of the Week is “The Pioneering Odyssey of Freeman Dyson, Maverick Genius” by Phillip F. Schewe, published in 2013. This is a biography of the multi-disciplinary mathematician / scientist, theorist, professor, author and lecturer.

The author named nearly all of the most famous twentieth-century nuclear physicists (and provided historical backdrop that led to scientific advances in physics, war and astronomy), and briefly described their contributions– even a few of whom Dyson hardly knew; that is, except for two scientists, who happened to be female:  Marie Cure and Lise Meitner. This oversight might be due to the fact that the author encountered little or no literature on them (due to their gender) when researching this book. Ironically, the author did admit, however, that Dyson’s marital troubles were due to his sexist hypocrisy.

Anyway, born in Great Britain in 1923, Dyson grew up in a wealthy family in the London suburb of Winchester. His mother was already 43 at his birth. Pursuant to family tradition, he was sent to boarding school at eight years old. Due to WWII, in two years rather than four, he earned a degree in mathematics at Cambridge University.

Dyson was then tapped to use his newly acquired knowledge as a tactical aviation consultant of sorts for the war effort, staying stateside. Postwar, as a graduate, he resumed his education, studying physics at Cambridge and Cornell universities. He never did finish his PhD.

Nevertheless, of all his lifetime’s workplaces, the Institute for Advanced Study at Princeton was where he spent the longest total time. In the late 1940’s, he was supervised by J. Robert Oppenheimer. He explained the missing link between Richard Feynman’s, Julian Schwinger’s and Shin’ichiro Tomonaga’s ideas about field theory in nuclear physics; more specifically, quantum electrodynamics.

Yes, Dyson did rocket science, too, at the dawn of the 1960’s. However, it was all theoretical. He actually wanted to go on a mission to Mars or Saturn or Jupiter. Dyson’s fluency in Russian allowed him to understand the Soviet mentality on the space and arms races.

Paradoxically, during the Cold War, an adverse consequence of the testing of nuclear weapons included cancer deaths due to radiation exposure; about a thousand of them annually. This was an acceptable sacrifice (in the name of saving the world)– as highway deaths numbered about fifty thousand annually. That changed of course, with nuclear accidents and seat belts in later decades.

In 1976, Dyson supervised a graduate student who wrote a term paper that generated much controversy.  “From non-classified government documents, freely available to anyone, Phillips [the student] proceeded to gather a primer of frightening specificity showing step by step how to build a nuclear bomb.” The student got an “A.”

Read the book to learn of Dyson’s views on extraterrestrials and extrasensory perception, on how religion and science can coexist; his fantasies about what humans could do in outer space in the future; his participation in a think tank named Jason, his take on global warming, the reversal of his beliefs on nuclear matters, and much more.

In Search of Memory – BONUS POST

The Bonus Book of the Week is “In Search of Memory” by Eric R. Kandel, published in 2006. This book was mostly about neurology and psychoanalysis. The autobiographical parts included descriptions of how and why the author’s family fled Austria for the United States in 1939, and his role in reconciling psychology and biology.

Kandel identified himself as Jewish. He explained that “racial anti-Semitism” is the idea perpetrated by the Catholic Church that the Jews killed Christ and therefore, they are members of “… a race so innately lacking in humanity that they must be genetically different, subhuman.” Such idea was used to justify genocide during the Spanish Inquisition and of course, the Holocaust. Gentiles in Germany, Poland and Austria especially, took up the cudgel of racial anti-Semitism during the Holocaust.

However, what is interesting is, that while the Catholic Church calls the Jews a “race” as a putdown, the Jews think of it as a point of pride.

When American Jews use the term”born Jewish” ironically, most are unaware of the belief that Jews as a group are thought by anti-Semites to have genes in common that bring out their stereotyped, negative traits. By born Jewish, they mean to say, they, like religious Jews, believe that Jews are automatically Jews regardless of their beliefs or observances, because their mothers were Jewish. Not in a derogatory way.

But wait. If people can convert to or from Judaism, it’s not genetic. Hindu people could actually call themselves a “race” because they allow no conversions. That’s the difference. The Hindus were a group of people who did all share the same genes up until the time they started marrying non-Hindus and having children.

By the way, read the book to learn about the progression of the fields of neurology and psychology in the twentieth century.

Extreme Measures

The Book of the Week is “Extreme Measures” by Martin Brookes. This is a biography of Francis Galton.

Galton was born in Birmingham in 1822, the youngest of seven children of a wealthy, prominent family in the Victorian Era. During his third year at Cambridge University, Galton had a mental breakdown. Ironically, he wrote, “…life seemed a game, played for the benefit of a select few, and from which he had been excluded…”

Galton had two major passions in his life:  a) exploring Africa, specifically Namibia– where he reported on navigation, land formations, climate, flora, fauna and its tribes– at the time, territory uncharted by Europeans; and b) collecting data on humans and what made them tick. He coined the expression “nature” or “nurture” to describe the roles played by genetics or the environment on people’s behavior and circumstances. He also labeled the statistical concepts of “regression” and “correlation.”

“Eugenics, his socio-scientific philosophy of the future would be built, according to Galton, on a solid foundation of knowledge, and exercised through a ruthless system of competitive examinations.”

Through the decades, other science projects of Galton’s included but were not limited to tea brewing, and a fingerprints database for law enforcement. Read the book to learn of the contents of the resulting publications, and how Galton seized upon the intellectual ideas of his generation, in a way that allowed him to achieve a minor footnote in the history books.
