C0 C1 F2 0a quark is a fundamental constituent of matter G3 F4 C5 1Observed in 1968 through deep elastic scatter. C6 C7 F8 2We found that protons aren't as simple as we thought. G9 F10 C11 3We thought they were solid particles but they are not. 4 5 C12 C13 F14 6Protons in fact are made up of three separate pieces. G15 F16 C17 7It just gets more confusing as our knowledge increases. C18 C19 F20 8But that is what a quark is; It's a piece of a proton, G21 F22 C23 9And they also make up other things including the neutron. 10 11 C24 C25 F26 12Oh, up, down, strange, charm, top, bottom G27 F28 C29 13If you don't know what a quark is, it don't matter you still got 'em. C30 C31 F32 14And with leptons and bosons, unless something's amiss, G33 F34 C35 15They make up everything that we can see and that we know exists. 16 17 C36 C37 F38 18Things made up of quarks including protons and neutrons G39 F40 C41 19Are composite particles that physicists call hadrons. C42 C43 F44 20Many types of hadrons are theoretically described, G45 F46 C47 21But most exist for only very brief amounts of time. 22 23 C48 C49 F50 24Quarks have electric charge, color charge, mass and spin, G51 F52 C53 25And having color charge means they exist solely inside of C54 C55 F56 26Other kinds of particles and cannot exist alone. G57 F58 C59 27Which is why quarks have never been studied on their own. 28 29 C60 C61 F62 30Up, down, strange, charm, top, bottom G63 F64 C65 31If you don't know what a quark is, it don't matter you still got 'em. C66 C67 F68 32And with leptons and bosons, unless something's amiss, G69 F70 C71 33They make up everything that we can see and that we know exists. 34 35 C72 C73 F74 36Quarks can join together in two different ways, G75 F76 C77 37Baryons and Mesons, but most instantly decay. C78 C79 F80 38If a particle has three quarks, then it's a baryon, G81 F82 C83 39If there's one quark and and anti-quark, then it is a meson. C84 C85 F86 40These tiny bits of matter are a part of almost everything G87 F88 C89 41And there is no unified theory to make it less confusing. C90 C91 F92 42But the fact that we've identified that they exist at all G93 F94 C95 43Is so god damn remarkable that I just sit in awe. 44 45 C96 C97 F98 46Oh, up, down, strange, charm, top, bottom G99 F100 C101 47If you don't know what a quark is, it don't matter you still got 'em. C102 C103 F104 48And with leptons and bosons, unless something's amiss, G105 F106 C107 49They make up everything that we can see and that we know exists.
