Capo 3 C5 C5 F5 A quark is a fundamental constituent of matter G5 F5 C5 Observed in 1968 through deep electric scatter C5 F5 We found that protons were more complex than we thought G5 F5 C5 We thought they were solid particles but they are not C5 F5 Protons in fact are made up of three separate pieces G5 F5 C5 It just gets more confusing as our knowledge increases C5 F5 And that is what a quark is; it?s a piece of a proton G5 F5 C5 And they also make up other things including the neutron C5 F5 Up down strange charm top bottom G5 F5 C5 If you don?t know what a quark is it doesn?t matter, you still got em C5 F5 And with leptons and bosons unless something?s amiss G5 F5 C5 They make up everything that we can see and that we know exists C5 C5 F5 Things made up of quarks including protons and neutrons G5 F5 C5 Are composite particles that physicist call hadrons C5 F5 Many times those hadrons are theoretically described G5 F5 C5 But most exist for only very brief amounts of time C5 C5 F5 Quarks have electric charge, colour charge, mass and spin G5 F5 C5 And having colour charge means they exist solely in side C5 F5 Other kinds of particles that cannot exist alone G5 F5 C5 Which is why quarks have never been studied on their own C5 F5 Up down strange charm top bottom G5 F5 C5 If you don?t know what a quark is it doesn?t matter, you still got em C5 F5 And with leptons and bosons unless something?s amiss G5 F5 C5 They make up everything that we can see and that we know exists C5 C5 F5 These tiny bits of matter are part of almost everything G5 F5 C5 There is no unified theory to make it less confusing C5 C5 F5 But the fact that we?ve identified that they exist at all G5 F5 C5 Is so remarkable that I am constantly in awe C5 F5 Up down strange charm top bottom G5 F5 C5 If you don?t know what a quark is it doesn?t matter, you still got em C5 F5 And with leptons and bosons unless something?s amiss G5 F5 C5 They make up everything that we can see and that we know exists
