You can say that QCD is the opposite of QED. I don't know how much you know of Renormalization group, but QCD has an asymptotic freedom, that mean that when you go to higher energies, you can use ...

You have to put net force to zero. I think that the problem is that you use the same volume for the two formulas. In one you have the entire volume, in the other only the volume in the water.

Calculating the magnetic field due to a rotating ring using Biot–Savart law
Accepted answer

I think that the problem is that you are considering an electric current at distance $r=0$ with the Biot-Savart formula. It's like when you have a wire with a current and you want to find magnetic ...

Well the problem is your concept of infinitesimal. You see the picture with a macroscopic $dA$, it isn't a real situation, it's to make you understand. You have to do $dA \rightarrow 0$, in this limit ...

We need to have: $$P_{fusion}>P_{loss}$$ To do so, we begin by defining a new quantity $\tau$ , called the confinement time, which measures the rate at which a system loses energy to its ...

CP-violation in standard model is due to CKM complex phase of the quarks sector. You can see the parametrization of CKM matrix, like Wolfenstein parametrization, and see that there is only a phase in ...

Sorry, but I don't understand what you mean when you say that quarks have a structure. What we know is that quarks are point-like particle, like was confirmed from SLAC years ago. Quarks aren't so ...

Why does virtual negative W boson decay mainly into antiup and down quarks during weak decays of lambda, Xi, omega and other baryons

I think that you are looking for the helicity suppression, this is simpler to understand for the decay of a $\pi$. In leptonic decays you can separate the hadronic part and the leptonic one. You will ...

What are the six quark mass values when extrapolated to Planck energy?

I think that your idea of mass is a little wrong. The quark mass is given in a renormalization scheme, if you change it you would have different masses for quarks. But for example the pair production ...
