The Standard Model of Particle Physics is a well-established theory that describes the fundamental particles and their interactions, except for gravity. It provides a comprehensive framework for understanding the forces and constituents of matter at the most fundamental level. Developed throughout the 20th century, the Standard Model combines Quantum Electrodynamics (QED), Quantum Chromodynamics (QCD), and…

Quantum Field Theory (QFT) is a fundamental framework in theoretical physics that extends quantum mechanics to fields and incorporates special relativity. It describes how particles interact through quantum fields and is essential for understanding the behavior of fundamental particles and forces in the universe.

Electromagnetism is a branch of physics that studies the interactions between electric and magnetic fields and their effects on matter. It is one of the four fundamental forces of nature, alongside gravity, the strong nuclear force, and the weak nuclear force. Electromagnetism encompasses a wide range of phenomena and is described by Maxwell’s equations in…

Quantum Electrodynamics (QED) is the quantum field theory that describes how light and matter interact. It is a fundamental part of the Standard Model of particle physics and provides a framework for understanding electromagnetic interactions at the quantum level. Developed in the mid-20th century, QED combines the principles of quantum mechanics with the electromagnetic force…
