Capo 3


A quCark is a fundamental cConstituent of mFatter

GObserved in 1968 through Fdeep electric scCatter

We Cfound that protons were more coFmplex than we thought

We Gthought they were solid particles but Fthey are noCt

CProtons in fact are made up of three separateF pieces

It just gGets more confusing as our kFnowledge iCncreases

And tChat is what a quark is; it?s a piece of Fa proton

And they alGso make up other things inFcluding the neuCtron

CUp down strange charm tFop bottom

If you dGon?t know what a quark is it doesn?t matFter, you still got Cem

And with leCptons and bosons unless somethingF?s amiss

They make up eGverything that we can see and thFat we know exCists

CThings made up of quarks including prCotons and neutrFons

GAre composite particles that physicist call haFdronsC

CMany times those hadrons are theoretically descFribed

GBut most exist for only very brFief amounts oCf time

CQuarks have electric charge, colour cCharge, mass and sFpin

And haGving colour charge means they exist soFlely inC side

COther kinds of particles that cannot exist aFlone

Which is wGhy quarks have never been stFudied on their oCwn

CUp down strange charm tFop bottom

If you Gdon?t know what a quark is it doesn?t matFter, you still got Cem

And with lCeptons and bosons unless somethingF?s amiss

They make up eGverything that we can see and thFat we know exCists

These tCiny bits of matter are part of alCmost everythFing

There iGs no unified theory to maFke it less confuCsing

But the faCct that we?ve identified that thCey exist at allF

Is soG remarkable that I am consFtantly in aCwe

CUp down strange charm tFop bottom

If you doGn?t know what a quark is it doesn?t matFter, you still got Cem

And with lepCtons and bosons unless somethingF?s amiss

They make up evGerything that we can see and Fthat we know exCists
