Now then, in string theory, Feynman diagrams are replaced by surfaces, and wordlines turn into world-sheets. This is because the strings oscillate in space and time, ...

Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings ...

Through the work of Feynman, Dyson, Julian Schwinger and Sin-Itiro Tomonaga, a new and improved theory of quantum electrodynamics was born. Feynman’s lines and squiggles, which became known as Feynman ...

But the type of geometric space that characterizes most Feynman diagrams is warped in a way that resists many cohomology calculations. In 2017, Mizera was struggling to analyze how objects in string ...

Richard Feynman looked tired when he wandered into my office. It was the end of a long, exhausting day in Santa Barbara, sometime around 1982. Events had included a seminar that was also a ...

This short story is taken from Riffing on Strings (Scriblerus, 2008) and is reproduced with kind permission of the publishers. Not long after the Fourth String Theory Revolution, the Institute of ...

Generations of physicists have spent much of their lives using Richard Feynman's famous diagrams to calculate how particles interact. New mathematical tools are simplifying the results and ...

Tufte is a Yale professor, statistician and artist who has written four books on analytical design. In his search for the effective data visualizations, Tufte was inspired by Feynman's book QED: The ...
