A quark is a fundamental constituent of matter
Observed in 1968 through deep electric scatter
We found that protons were more complex than we thought
We thought they were solid particles but they are not
Protons in fact are made up of three separate pieces
It just gets more confusing as our knowledge increases
And that is what a quark is; it?s a piece of a proton
And they also make up other things including the neutron
Up down strange charm top bottom
If you don?t know what a quark is it doesn?t matter, you still got em
And with leptons and bosons unless something?s amiss
They make up everything that we can see and that we know exists
Things made up of quarks including protons and neutrons
Are composite particles that physicist call hadrons
Many times those hadrons are theoretically described
But most exist for only very brief amounts of time
Quarks have electric charge, colour charge, mass and spin
And having colour charge means they exist solely in side
Other kinds of particles that cannot exist alone
Which is why quarks have never been studied on their own
Up down strange charm top bottom
If you don?t know what a quark is it doesn?t matter, you still got em
And with leptons and bosons unless something?s amiss
They make up everything that we can see and that we know exists
These tiny bits of matter are part of almost everything
There is no unified theory to make it less confusing
But the fact that we?ve identified that they exist at all
Is so remarkable that I am constantly in awe
Up down strange charm top bottom
If you don?t know what a quark is it doesn?t matter, you still got em
And with leptons and bosons unless something?s amiss
They make up everything that we can see and that we know exists
