Protons and neutrons have spin 1/2 and are known to be the building blocks of matter. They are the bound states of quarks and gluons, whose dynamics is best described by Quantum Chromodynamics (QCD). I will briefly review how to express the proton spin in terms of the degrees of freedom of quarks and gluons. It is a challenge to directly measure individual contribution of quarks and gluons to the proton spin. I will show that high energy collisions with measured polarization offer many new opportunities to probe QCD dynamics that could not be reached by spin-averaged collisions. A successful spin program could shed the light on how QCD encompasses both protons and neutrons and the quark and gluon degrees of freedom that make them up.
