Making precise predictions for the strong interactions of quarks and gluons has eluded physicists for many decades. However, recent gains in algorithms and computer power have made it now possible through numerical simulation to calculate some quantities to a couple percent accuracy. These calculations are now contributing to the accurate determination of some fundamental constants in nature. I will tell the story and show some recent results.
