Jefferson Lab–NVIDIA Collaboration Uses Titan to Boost Subatomic Particle Research

Scientists are only beginning to understand the laws that govern the atomic world. Before the 1950s the electrons, neutrons, and protons comprising atoms were the smallest confirmed units of matter. With advancements in experimental and theoretical techniques in recent decades, though, researchers now try to understand even smaller particles at…
