The Secret to the Strongest Force in the Universe

Physicists are finally getting to grips with the mysterious strong force, which binds quarks into protons and neutrons and holds the nucleus together. The physicists who made the first measurements in the range of distances where the strong force becomes especially strong and difficult to calculate, and came up with theoretical predictions to match, describe their breakthrough. We at last have the ability to calculate aspects of quantum chromodynamics — the fiendishly complex theory that describes how the force works — from first principles
