The weak force gets weaker as you move further apart, it's just very, very quickly, um exponentially quickly.
So that um it it only affects tiny, tiny distances like atomic nucleus scale, or even smaller than the nucleus actually.
The weak force is so named because over the relevant scales, it's weaker than either the electromagnetic or the strong force.
At the scale of quarks, it's about it's about one ten thousandth of the strength of the electromagnetic force.
Remember that strong force at that scale is about 60 times.
So the order is strong, then electromagnetic, and then weak uh at at that uh at that scale.
Gravity, by the way, is way down.
It's it's if electromagnetic has a strength of one.
Mm-hmm.
then a weak has a strength of ten to the minus four.
Gravity has a strength of ten to the minus forty-one, uh uh estimated.
Uh so it's absurdly weak compared to the other forces.
And um that why that is is one of the open questions of well of all of physics really, as to why gravity is so different.
Okay, so that's an introduction to the three main forces that we're going to be discussing: electromagnetism, the strong nuclear force, and the weak nuclear force.
Now, we're going to try to systematize this a bit and try to bring a bit of order to all the particles we've been talking about by um discussing kind of like the periodic table of fundamental particles.
Uh it's not called that, but that's sort of what it is to help conceptualize what we're talking about.
There's a particular way of visualizing and arranging the particles to emphasize their commonalities and differences.
And and this is one way that if you like Google standard model, you often see this diagram as an illustration of what the standard model is.
is it's sort of this description, systematic description of the different particles.
So to start with, let's make a distinction between fermions and bosons.
