Graduate Student Seminar with Jason Bub on The Charge of Color

In fundamental physics, three of the four forces have been described by quantum theory. The last of these was the strong nuclear force, explained by Quantum ChromoDynamics (QCD). Underlining QCD is a hidden SU(3) symmetry, which gives rise to a sub-nuclear charge. To this charge, we ascribe the name: color charge. If we follow the path to the source of this convention, we can find how color itself makes an unexpected connection to quantum mechanics. And if we continue to pull on that string we investigate color through its role in human expression and application. And if we pull long and hard enough, we start to unravel effects that range from perception to interesting physics in optics and fluids.
