A pretty Quark model
I might send a comic book to Paul for Christmas
or a 4D clifford torus T-shirt .
Australians are an adaptable bunch..
"now we've got three valency quarks
which is the green the blue in the red did you see there
and then there's a whole bunch of squiggly stuff
those are our gluons just buzzing in and out
but those gluons interact to produce quarks and antiquarks
in and out of existence inside the proton
and so in essence our proton isn't a sphere with things built in .
no no it's basically those 3 valency quarks and other quarks
popping in and out of existence
and a multitude of gluons buzzing around inside there
and the only thing that is keeping them on the edge edge here
is basically the strong nuclear force that's holding them all in together
in essence the proton edge is the boundary that stops them from going any further
