Capo 3 C C F A quark is a fundamental constituent of matter G F C Observed in 1968 through deep electric scatter C F We found that protons were more complex than we thought G F C We thought they were solid particles but they are not C F Protons in fact are made up of three separate pieces G F C It just gets more confusing as our knowledge increases C F And that is what a quark is; it’s a piece of a proton G F C And they also make up other things including the neutron C F Up down strange charm top bottom G F C If you don’t know what a quark is it doesn’t matter, you still got em C F And with leptons and bosons unless something’s amiss G F C They make up everything that we can see and that we know exists C C F Things made up of quarks including protons and neutrons G F C Are composite particles that physicist call hadrons C F Many times those hadrons are theoretically described G F C But most exist for only very brief amounts of time C C F Quarks have electric charge, colour charge, mass and spin G F C And having colour charge means they exist solely in side C F Other kinds of particles that cannot exist alone G F C Which is why quarks have never been studied on their own C F Up down strange charm top bottom G F C If you don’t know what a quark is it doesn’t matter, you still got em C F And with leptons and bosons unless something’s amiss G F C They make up everything that we can see and that we know exists C C F These tiny bits of matter are part of almost everything G F C There is no unified theory to make it less confusing C C F But the fact that we’ve identified that they exist at all G F C Is so remarkable that I am constantly in awe C F Up down strange charm top bottom G F C If you don’t know what a quark is it doesn’t matter, you still got em C F And with leptons and bosons unless something’s amiss G F C They make up everything that we can see and that we know exists
