Calculational Methods


Stephen Wolfram discusses the calculational methods that Richard Feynman developed for particle physics. Feynman was known for his remarkable ability to perform complex calculations in quantum field theory and to develop intuitive frameworks for understanding difficult concepts. Interestingly, he considered these calculations easy and often didn’t share the details, preferring to present only the simplified intuitive insights. This approach occasionally left others mystified, especially when they tried to follow his intuition without understanding the underlying calculations that supported it. Additionally, Wolfram describes instances of working with Feynman on quantum computers during 1980-81, revealing how their approaches differed, with Feynman preferring handwritten calculations and Wolfram using computer simulations, leading to disagreements and deeper explorations of concepts [1 ].

Feynman's Calculational Methods

Stephen Wolfram shares Feynman's attempt to systematize the ways of doing integrals that show up in particle physics. Feynman was good at calculating stuff but thought it was easy and invented simple intuition about how everything works.
