Classical field theory is a research area in theoretical physics that studies continuous fields, such as electromagnetic, gravitational, and scalar fields, within a pre-quantum, typically relativistic ...

Susskind and Friedman follow their collaboration on Quantum Mechanics by probing the mathematical nitty-gritty of field theory and Einstein’s theory of special relativity in the third installment of ...

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 ...

Quantum algorithms for simulating electronic ground states are slower than popular classical mean-field algorithms such as Hartree–Fock and density functional theory but offer higher accuracy.

Since 2007, physicist Leonard Susskind has regularly delivered a lecture series called the Theoretical Minimum, on the foundations needed to study different areas of ...

Physicists speak of the world as being made of particles and force fields, but it is not at all clear what particles and force fields actually are in the quantum realm. The world may instead consist ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you wanted to answer the question of what's truly fundamental in ...

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 ...
