A lecture by the pioneer of Effective Field Theories (EFTs), Nobel Laureate Steven Weinberg, has been published. This introduces the concept of EFTs, their historical development and their application ...

Quantum field theory says true nothingness doesn’t exist; even a vacuum teems with energy fields that help create matter and ...

An old puzzle in particle physics has been solved: How can quantum field theories be best formulated on a lattice to optimally simulate them on a computer? The answer comes from AI. A hundred years ...

Starting with her title, Field Theories, Samiya Bashir challenges the vocabulary of science, finding inflections and echoes within that vocabulary of the long and brutal history of race and racially ...

Geometric field theories in higher dimensions encompass a broad class of frameworks that extend the familiar four-dimensional description of spacetime to manifolds of greater dimensionality, often ...

Over the past century, a wide variety of models have emerged to explain the complex behaviours which unfold within atomic nuclei at low energies. However, these theories bring up deep philosophical ...

Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical ...

What is a quantum field and how does it interact with matter? originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better understand the ...

A new study just added an interesting twist to the complicated history of the physics theory.

The fundamental particles of the universe that physicists have identified—electrons, neutrinos, quarks, and so on—are the "letters" of all matter. Just like their linguistic counterparts, they appear ...
