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 ...

It should perhaps then be justified why this should be treated as such a significant advancement in scattering amplitudes, when Feynman diagrams have proven reliability outside of a toy theory.

Now then, in string theory, Feynman diagrams are replaced by surfaces, and wordlines turn into world-sheets.

Richard Feynman's famous diagrams embody a deep shift in thinking about how the universe is put together.

Not long after the Fourth String Theory Revolution, the Institute of Higher Dimensions made plans to house the exponentially-growing collection of string theory papers in a new library.

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 ...

Using Feynman diagrams Often, they will just rebound But now and then they go another way A quantum Loooooop Infinities will make you cry Unless you can renormalize your model Of baryons, fermions ...
