So at this point I've introduced to you the fermions and the bosons.

We've talked about the three different classes of bosons, your gluons, your photons, and your WZ bosons, one one class for each of the three forces.

And then we've talked about quarks, which make up protons and neutrons in the nuclei.

We've talked about electrons, we know a lot about electrons already.

And we've talked about neutrinos, which are mostly involved in like radioactive decay.

So at this point I'm going to introduce another distinction between quarks and leptons.

So quarks, I've already talked about how they uh are involved in the strong nuclear force.

Leptons, we we've already met the leptons, that's just I'm introducing a new name for them.

Leptons are electrons and neutrinos.

They are grouped together as leptons.

Why are they grouped together?

Well, there's deeper reasons for this.

The simplest way to understand the difference is that quarks feel the strong force, whereas leptons do not.

So quarks have a color charge, which means that they experience the strong force.

Whereas leptons do not have a color charge, so they do not experience the strong force.

Pretty simple.

Okay, so that's another distinction.

Let let me review where we are at this point.

At this point, I've introduced to you four types of matter particles and three types of energy particles.

The matter particles are fermions, they have spin half.
