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 ...

Richard Feynman's famous diagrams embody a deep shift in thinking about how the universe is put together. Richard Feynman looked tired when he wandered into my office. It was the end of a long, ...

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 ...

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, ...

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 ...

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 suggesting ...
