Questions & Answers

Q: What led Simons to work for the NSA?

Simons joined the NSA because they had a program at Princeton where mathematicians were hired to crack secret codes. The opportunity to work on both his own mathematics and the NSA's projects, as well as the high salary, made it an irresistible opportunity for him.

Q: Why did Simons get fired from the NSA?

Simons got fired because he publicly expressed his opposition to the Vietnam War. He wrote a letter to the New York Times criticizing his superior's views on the war, which led to his dismissal.

Q: How did Simons start working with Shiing-Shen Chern?

Simons had known Chern since his graduate student days at Berkeley. He brought some mathematical ideas to Chern, who liked them, and they began collaborating on a famous paper together.

Q: What was the work that Simons and Chern did together?

Simons and Chern's work was in algebraic topology, specifically related to spheres and their properties. While Simons admits it's difficult to explain the work, he notes that it was highly influential in mathematics and also found unexpected applications in physics, such as string theory and condensed matter physics.

Q: How did Simons achieve remarkable returns with low volatility in the financial industry?

Simons attributes his success to assembling a talented team of mathematicians and scientists. They developed mathematical models and algorithms to analyze vast amounts of data, looking for anomalies and developing predictive schemes. By continuously improving and adapting their models, they were able to achieve high returns with comparatively low risk.

Q: What kind of data did Simons and his team analyze?

Simons and his team analyzed a wide range of data, including weather patterns, quarterly reports, interest rates, historical data, and more. They collected terabytes of data daily and looked for patterns and anomalies that could be exploited in their trading strategies.

Q: Are there concerns about the hedge fund industry attracting too much talent and contributing to inequality?

Simons acknowledges that the hedge fund industry has been criticized for creating wealth and attracting top talent, potentially exacerbating income inequality. However, he believes that the incorporation of science and mathematics into investing has improved the industry by reducing volatility and increasing liquidity.

Q: What philanthropic initiatives has Simons been involved in?

Simons and his wife Marilyn founded the Simons Foundation, which focuses on supporting math and science research. They also started Math for America, a foundation that invests in math teachers and aims to improve math education in the United States.

Q: What is the goal of Math for America?

Math for America aims to celebrate and support excellent math teachers by providing extra income, coaching, and recognition. The foundation believes in celebrating good teachers rather than focusing solely on poor ones. Their goal is to enhance the status and appeal of the teaching profession, particularly in math and science.

Q: What does Simons say about the origins of life and the possibility of extraterrestrial life?

Simons finds the origins of life fascinating and believes there are two key questions: the path from geology to biology and the initial material available for life. He mentions that organic molecules, potential building blocks of life, have been found in the dust surrounding forming stars. While the path to life may be tortuous and rare, there is the possibility of life on other planets.

Takeaways

Jim Simons' life and career demonstrate the power of mathematics and science. From his early days as a code-cracker to his groundbreaking work in mathematics and his success in the financial industry, Simons consistently applied mathematical principles to achieve remarkable results. His philanthropic efforts, particularly in math education and research, reflect his belief in the transformative potential of knowledge.
