Physicists Nima Arkani-Hamed and Jaroslav Trnka recently published a significant advance in the study of Scattering Amplitudes. These are formulas that physicists use to calculate everything from the ...
Illustration of a polaron in a crystal: the central bright sphere is the charge carrier, distorting the surrounding lattice. The wavy lines represent high-order Feynman diagrams for the ...
Illustration of a polaron The bright sphere is the electron, which is distorting the surrounding lattice. The wavy lines are high-order Feynman diagrams for the electron–phonon interaction. (Courtesy: ...
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 ...
Richard Feynman's famous diagrams weren’t just a way to do calculations. They represented a deep shift in thinking about how the universe is put together. Betting on the Future of Quantum Gravity New ...
I've been covering chemistry software in my last few articles, so this time, I decided to move to physics and introduce a package called JaxoDraw. In physics, there's a powerful technique for ...
Science Daily – Combining known factors in a new way, theoretical physicists Boris Svistunov and Nikolai Prokof’ev at the University of Massachusetts Amherst, with three alumni of their group, have ...
It was World War II and scientists belonging to the Manhattan Project worked on calculations for the atomic bomb. Meanwhile, in one of the buildings, future Nobel Prize winning theoretical physicist ...
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 ...
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, ...
