26. Quantum chromodynamics is a quantum field theory which describes the strong
interaction between the quarks and gluons which make up protons and neutrons. But,
our standard method of calculating, perturbation theory, fails in this regime because
the coupling constant between particles is strong and we are not able to expand
around the non-interacting state. Therefore, we use the AdS/CFT correspondence to
map the field theory to a spacetime with gravity in one higher dimension, a system for
which we can do calculations.

28. Quarks and gluons are tiny particles which make up protons, and we can write down
the math that describes how they behave. But, we do the calculations to find out how
they behave using our normal approaches--it’s like trying to tighten a screw with a
hammer. Therefore, we use a newly developed theoretical tool which rewrites the
calculation as a problem that we know how to solve.
