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, ...

Unlock the secrets of Feynman Diagrams. Part 5 in our Quantum Field Theory series. Unlock the secrets of Feynman Diagrams. Part 5 in our Quantum Field Theory series.

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 ...

Max Planck researchers have used Feynman diagrams to formulate what they need to do to create a complete picture from incomplete data. In the simplest case, known as the Wiener filter, you conclude ...

Back in 1948, the journal Physical Review published a paper entitled “Space-Time Approach to Quantum Electrodynamics” by a young physicist named R.P. Feynman at Cornell University. The paper described ...

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 ...
