Feynman Diagrams. The equations of quantum field theory allow us to calculate the behaviour of subatomic particles by expressing them as vibrations in quantum fields.

Feynman diagrams are incredibly useful, but they're a perturbative (i.e., approximate) approach to calculating, and quantum field theory often yields fascinating, unique results when you take a ...

So, yeah, quantum field theory is a type of madness. An again, we've been down that rabbit hole. In particular, we've looked a bit at Feynman diagrams, which are our best tool for dealing with the ...

We all love Richard Feynman, but his diagrams may have to go. We all love Richard Feynman, ... Arkani-Hamed and Trnka hope to gain a deeper understanding of the nature of quantum field theory.

/ FromQuarkstoQuasars / Amplituhedron / Feynman Diagrams / Quantum Mechanics. ... This was an expression computers of the time could handle, and quantum field theory got a little more manageable.

Indeed, the most accurate physical theory yet devised is quantum electrodynamics, the quantum field theory account of electricity, magnetism, and light, and it owes its great success to weak coupling.

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

This theory merges classical field theory, quantum mechanics, and special relativity. ... Feynman diagrams and the corresponding momentum-space rules for unified gravity in the SI units.

Quantum Entanglement is the biggest mystery of science that could upend life as we know it, and explaining it is an unlikely but fascinating theory writes Satyen K. Bordoloi. It is the stuff of ...
