Physical interpretation of Feynman path integral

In summary, the conversation discusses the nature of quarks, which are particles that make up atomic nuclei. When probed with high energy electrons, quarks appear to be hard bodies, but this is due to the relativistic relationship between the electrons and the quarks. From the Standard Model, quarks are considered to be concentrations of field strength. The conversation also touches on the topic of Feynman path integrals and how it relates to the study of quarks.

so I herd that atpms are actuall blob like particles insted of hard crystal orb like things but are quarks the same way? are quarks like blobs too?

When atomic nuclei are probed with high energy electrons, the quarks seem like hard bodies ("partons") that bounce the electrons back elastically, but this is at least partly due to the relativistic relationship between the fast moving electrons and the slow moving quarks.

When calculated from the Standard Model, quarks are standard quantum field theory "particles", that is, concentrations of field strength, strong in the midddle and tailing off outside.

Could you elaborate a little inorder to "visualize" (if possible) how this relativistic relationship produces elastic collisions.

Hope this isn't too off topic.

Thanks

did quarks or any kind of particle ever have a beginning to it?

I split off these last few posts from the main Feynman path integrals discussion because they were OT for that subject.

As to an explanation of partons, I think http://www.pparc.ac.uk/frontiers/pdf/6F2.pdf gives a good account at the popular level.

Can i say what is the relation between this subject and Feynman path integrals?
 

1. What is Feynman path integral?

Feynman path integral is a mathematical formulation in quantum mechanics that describes the evolution of a quantum system over time. It is based on the principle of superposition, which states that a particle can exist in multiple states simultaneously, and the path integral takes into account all possible paths that the particle could take from one state to another.

2. How is Feynman path integral used in physics?

Feynman path integral is used to calculate the probability amplitude for a particle to transition from one state to another. This can be used to make predictions about the behavior of particles in various physical systems, such as the movement of electrons in a magnetic field or the behavior of subatomic particles in particle accelerators.

3. What is the physical interpretation of Feynman path integral?

The physical interpretation of Feynman path integral is that it represents the sum of all possible paths that a particle can take between two points in space and time. This includes both classical paths and quantum paths, and the contribution from each path is weighted by its probability amplitude.

4. How does Feynman path integral relate to the Heisenberg uncertainty principle?

Feynman path integral is closely related to the Heisenberg uncertainty principle, which states that the position and momentum of a particle cannot be precisely known at the same time. The path integral takes into account all possible paths, including those that violate the classical laws of motion, which allows for a better understanding of the uncertainty inherent in quantum systems.

5. What are some applications of Feynman path integral in modern physics?

Feynman path integral is used in many areas of modern physics, including quantum field theory, condensed matter physics, and statistical mechanics. It has been used to successfully predict the behavior of subatomic particles, as well as to study the properties of materials at the atomic level. It is also a key tool in the development of quantum computing and quantum information theory.
