AI Thread Summary

The discussion centers on the Strong Interaction in particle physics, specifically highlighting the Yang-Mills Lagrangian as the governing equation. The Lagrangian is expressed as L = phibar(i*Dslash)phi - 1/4 * (F^i_uv)^2 - m*phibar*phi, where 'phi' represents the fermion (quark) field, 'F^i_uv' denotes the gluon field tensors, 'm' is the fermion mass, and 'D' is the covariant derivative associated with the SU(3) gauge group. This formulation underscores the fundamental aspects of the Strong Interaction and its role in quantum chromodynamics (QCD).

Is there a general equation for the Strong Interaction?

Yes -- the Langrangian is the Yang-Mills Lagrangian with the gauge group SU(3). ie

L= phibar(i*Dslash)phi - 1/4 * (F^i_uv)^2 -m*phibar*phi

where phi is the fermion (quark) field, F^i_uv is the gluon field tensor(s), m is the fermion mass, and D is the covariant derivative for SU(3).

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks

i want to just test a linear generator with galvanometer , the magnet is N28 and the wire (Cu) is of 0.6mm thikness and 10m long , but galvanometer dont show anthing , The core is PLA material (3d printed) The magnet size if 28mm * 10mm * 5mm

Thread 'Fundamental Probability'

If the universe is fundamentally probabilistic, and all possible outcomes are realized in some branch of the multiverse, does that invalidate the concept of scientific inquiry? If knowledge is merely a description of one particular branch of reality, does it have any inherent value?
