Quantum Electrodynamics (QED) and Quantum Electroweak Force (QEF) are two terms that most people have heard of, but many do not understand the difference between the two. Both theories are critical components of modern physics, but they represent different aspects of the same system. In essence, QED deals exclusively with the interactions between electrically charged particles, whereas QEF tackles the more fundamental interactions between all forms of fundamental matter; yet, both play vital roles in our understanding of the world.
Some scientists argue that QEF is the more comprehensive theory, as it encompasses all of the fundamental forces. Meanwhile, QED is more limited to interactions between charged particles and their associated fields. Additionally, QEF helps to explain some of the most fundamental questions about the universe, such as why particles have mass and why certain particles are more massive than others. In summary, while QED and QEF may seem similar at first glance, they are two fundamentally different theories that operate on separate scales and with separate scopes.

Origins and Definitions of QED and QEF
Quantum Electrodynamics (QED) and Quantum Electrochemistry (QEF) are two branches of physics that deal with the interaction between particles and electromagnetic fields. While they share some similarities, QED and QEF are fundamentally different in their origins and definitions.
QED is a fundamental theory that describes the interaction between electrically charged particles and electromagnetic fields. It emerged in the 1940s and 1950s as a culmination of the efforts of many physicists, including Richard Feynman, Julian Schwinger, and Sin-Itiro Tomonaga. QED is considered one of the most successful scientific theories ever developed, as it accurately predicts the behavior of particles to the highest degree of precision achievable by experiment.
On the other hand, QEF is a branch of electrochemistry that deals with the study of electron transfer reactions in solutions. QEF emerged in the late 20th century, when scientists became interested in understanding the fundamental processes that occur in redox reactions. Unlike QED, QEF is largely an empirical field, relying on experimental observations and measurements rather than theoretical predictions.

Mathematics Concepts Related to QED and QEF
In mathematical terms, QED stands for “Quantized Electrodynamics” and QEF stands for “Quantized Electron-Field Theory”. Both of these terms are used to describe the interactions between subatomic particles and electromagnetic fields.
- Quantized Electrodynamics (QED) – QED is a quantum field theory that describes the interactions between electrically charged particles, such as electrons and photons. It is based on the principle of gauge invariance, which requires that the theory is invariant under certain transformations.
- Quantized Electron-Field Theory (QEF) – QEF is a quantum field theory that describes the interactions between electrons and an electromagnetic field. It is based on the principle of electromagnetic gauge invariance, which requires that the theory is invariant under certain transformations.
Both QED and QEF are used to describe the behavior of subatomic particles, such as electrons and positrons, in the presence of an electromagnetic field. They are both very complex mathematical models that require a lot of computational power to solve. The differences between QED and QEF lie in their mathematical structures and the types of particles they describe.
QED predicts the existence of photons, the particles that make up electromagnetic radiation, and describes how they interact with other particles. It also predicts how particles can emit and absorb photons, which is the basis for phenomena like the photoelectric effect. QEF, on the other hand, does not predict the existence of photons, but instead focuses on the interactions between electrons and an electromagnetic field.
| Quantized Electrodynamics (QED) | Quantized Electron-Field Theory (QEF) |
