Jew of the Week: Richard Feynman

Revolutionary Physicist 

Richard Phillips Feynman (1918-1988) was born in Queens to Lithuanian Jewish immigrant parents. Before his birth, his father had decided that his son should be a scientist, and raised Feynman from an early age to question everything. Feynman did not speak his first word until he was three years old. In childhood, he loved to take things apart and even set up a lab in his home, hiring his little sister for 4 cents a week to be his assistant. (He would later inspire and encourage her to become a renowned astrophysicist in her own right.) At 15, he taught himself advanced algebra, calculus, and trigonometry. He applied to Columbia University but was rejected because the quota for Jewish students had been filled. Feynman went to MIT instead, first majoring in math, then electrical engineering, and finally physics. He published his first two papers as an undergrad, and his senior thesis (putting forth what would become the Hellmann-Feynman theorem) brought him a great deal of recognition in the scientific community. Feynman then applied to grad school at Princeton, and got an unprecedented perfect score on the physics exam. Again, he was initially brushed aside for being Jewish before the dean was convinced not to miss out on the young genius. (Feynman was admitted only on the condition that he wouldn’t get married!) At 23, he defended his Ph.D, and was already being compared to Einstein (he would win the Albert Einstein Award in 1954). Meanwhile, Feynman was working on the Manhattan Project, leading a team developing the isotron (to isolate uranium-235), then developing what’s now called the Bethe-Feynman formula for fission bomb yield. At Los Alamos, he was one of the “human computers”, and helped to develop better machinery for some of the world’s first digital computers. Towards the end, he spent time lecturing on the dangers of nuclear power, and put together a safety manual for uranium enrichment.

After the war, Feynman joined the faculty of Cornell University, and there developed his famous (and revolutionary) “Feynman diagrams” to solve and explain quantum problems more easily. After a sabbatical in Brazil, Feynman moved to Caltech, working on superconductivity, superfluidity, nuclear decay, and quantum gravity, among many other subjects. He is credited with being the first scientist to conceive of both nanotechnology and quantum computers. In the 1960s, he began writing books on physics, many of which went on to become bestsellers and university textbooks. In 1965, he won a Nobel Prize for his theory on quantum electrodynamics, and in 1979 won the National Medal of Science. Feynman became even more famous in 1986 when he lead the team that investigated the crash of the space shuttle Challenger. Feynman was voted by scientists as one of the 10 Greatest Physicists of All Time, and Bill Gates recently wrote an article (titled “The Best Teacher I Never Had”) about how it was Feynman that served as his greatest inspiration. Feynman was famous for his sense of humour and his rebellious nature. He rejected his religion (though at a later age encountered the Talmud and said it was “a wonderful book”), resisted his superiors (he was sought out by Niels Bohr because all the other physicists were too fearful to argue with the great Bohr), and even derided his Nobel Prize (saying the real prize was the scientific discovery). Feynman also loved biology and poetry, and was an avid painter and musician. Last Friday would have been his one hundredth birthday.

Words of the Week

As they set out from their place above, each soul is male and female as one. Only as they descend to this world do they part, each to its own side. And then it is the One Above who unites them again. This is His exclusive domain, for He alone knows which soul belongs to which and how they must reunite.

– Zohar (I, 85b)

Jew of the Week: Bernard Baruch

Bernard Baruch

Bernard Mannes Baruch (1870-1965) was born in South Carolina to German-Jewish immigrants. His father was a doctor specializing in hydrotherapy and appendectomies, and a key military surgeon in the Civil War. The family moved to New York City, where Baruch first worked as an office boy for $3 a week. After college, he became a stock broker and made a fortune trading sugar (though he would lose and regain his fortune several times). By 30, he was among the most successful financiers of all time, nicknamed “The Lone Wolf of Wall Street” as he worked independently and resisted joining a financial house. In 1916, Baruch left finance and became an adviser to President Woodrow Wilson. He was soon the chairman of the War Industries Board and managed America’s economic mobilization for World War I. At the end of the war, Baruch attended the Paris Peace Conference and was a central supporter of the League of Nations (the precursor of the UN). Baruch continued to advice future presidents, including Roosevelt, whom he helped to create the National Recovery Administration for fair business, industry and labour practices. After World War II, Baruch worked at the UN, particularly to stem nuclear arms proliferation. He would be sought as an adviser until the last days of his life, counselling a total of nine American presidents. He was famous for discussing global issues and politics while sitting on public benches in Central Park (in NYC) and Lafayette Park (in Washington, DC) and was thus called the “Park Bench Statesman”. Baruch was also a noted philanthropist throughout his life, contributing millions to charities and colleges. Click here to learn a few investment tips from Bernard Baruch.

There are free men with the spirit of a slave, and slaves whose spirit is full of freedom. He who is true to his inner self is a free man, while he whose entire life is merely a stage for what is good and beautiful in the eyes of others, is a slave.
Rabbi Avraham Itzhak Kook
