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 ...

A diagram of the double-slit experiment according ... of atomic and subatomic particles at normal speeds, while quantum field theory is the study of those same particles at relativistic speeds.

Feynman diagrams capture only the minimal ripples of a quantum field and nothing more. So the full picture—what physicists call a “nonperturbative” theory—might be beyond the reach of the ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum ...

A bold new quantum theory of gravity may finally bridge the long-standing rift between Einstein’s general relativity and quantum field theory. This potential "Theory of Everything" could answer some o ...

Bringing gravity into the fold has been the goal of generations of physicists, who have struggled to reconcile the incompatibility of two cornerstones of modern physics: quantum field theory and ...

One of the most profound open questions in modern physics is: "Is gravity quantum?" The other fundamental ...

Mathematicians call these line diagrams graphs. Now, in our theory, we throw away the drawings of polyhedra and just keep the graphs. The mathematics that describes the quantum states of volume ...

Space-time diagram of Prof. Yin's experiment ... Niels Bohr, one of the prime developers of quantum theory, once said that those who are not shocked when they first encounter quantum theory ...
