### What topics are studied in physics?

- classical mechanics - motion, velocity, acceleration, inertia, forces, momentum, etc. - electricity, magnetism, and light (electromagnetism) - wave mechanics - thermodynamics - quantum mechanics - quantum electrodynamics - quantum chromodynamics - superconductivity - general and special relativity - string theory and supersymmetry - cosmology (the list goes on and on)

### What are examples of field theory?

The most important quantum field theories are: *QED (quantum electrodynamics) the field theory of electromagnetic interaction, *QCD (quantum chromodynamics) the theory of the strong interaction of quarks and gluons. *The electroweak theory, which combines the so called weak interaction with QED *And of course the Standard Model of particle physics And many others...

### Who developed the theory of quantum electrodynamics?

Max Planck first proposed the idea of Quantum Theory in 1900. However, numerous physicist thought of this idea, one of the first, was Dirac in 1927 Quantum electrodynamics went beyond the work of Dirac, doing so in order to explain discrepencies between theory and experiment in hydrogen spectral line shifts. Inspired by an insight from Hans Bethe, Sin-Itiro Tomonaga, Julian Schwinger, Richard Feynman, and Freeman Dyson eventually developed a theory that resolved the discrepency. Tomonaga…

### What is QED?

Answer QED is an abbreviation for the Latin "quod erat demonstrandum" (literally, "which was to be demonstrated" or "thus it is demonstrated". It is used at the end of a proof or logical argument by the author to state that he has reached the end of his argument and proven his case. Answer Or it could be quantum electrodynamics.

### How does light reflect off of objects?

A photon is absorbed by an electron and then it is emmited to a different direction. Quantum electrodynamics can give you a better answer to your question. There is a book i have read recently called QED: The strange theory of light and matter which is a collection of Feynmann's lectures on QED that everyone can understand without knowing maths or quantum mechanics, and can explain very well how light and electrons interact.

### What is the science of matter called?

Physics. but its a huge subject and can be broken down into many fields I"E Quantum Mechanics / Quantum Physics - the study of science where the smallest discrete values, or quanta, of matter and energy become relevant Cosmology - the study of the universe as a whole, including its origins and evolution. Electromagnetism - the study of electrical and magnetic fields, which are two aspects of the same phenomenon. Molecular Physics - the study…

### What will be the theory after the quantum theory of light?

There is unlikely to be a successor to a quantum theory of light, by the definition that the quantum theory of light is that "Light is made up of discernible particles", has very strong evidence to support it, and no alternative explanation has yet been found to explain such effects as the photoelectric effect. If you mean quantum electrodynamics, the section of the standard model of particle physics that explains light, electricity and magnetism, and…
