Tools can change not only how theorists calculate but also what they calculate about. But two decades ago, Ursula Klein, a scholar from the Max Planck Institute for the History of Science in Berlin, ...

As one of the most famous physicists of the 20th century, Richard Feynman was known for a lot. Early in his career, he contributed to the development of the first atomic bomb as a group leader of the ...

geralt Physicist Richard P. Feinman received the Nobel Prize in Physics for contributing significantly to the development of quantum electrodynamics (QED). One of the achievements of Feynman Feynman ...

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 performance ...

Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings physicists use to represent particle interactions. The new method has already ...

I have always been surprised that Feynman diagrams were as usefull as they are. They seem so limited in what they can handle, but I guess for the "simple" problems needed to make nuclear powerplants, ...

The next time you get a letter, its stamp might have printed on it examples of one the greatest conceptual tools of modern physics. The tool is a kind of line drawing, and a bunch of those drawings ...

Before the explosion in 'infographics' describing everything from cocktail mixology to US health-care spending, there was Edward Tufte. Tufte, a statistician, is perhaps the world's most celebrated ...

One of the physics blogs I read regularly is ZapperZ's Physics and Physicists, where last week he posted an interesting observation about the difference between subjects when it comes to modes of ...
