Materials science bridges physics, chemistry, and engineering to explain why steel is strong, why glass is brittle, and why rubber stretches. Every material's macroscopic behavior emerges from its atomic structure — the arrangement of atoms in crystal lattices, the motion of dislocations under stress, and the thermodynamics of phase transformations.
These simulations let you explore material behavior interactively. Build crystal lattices atom by atom, stretch a virtual specimen until it fractures, navigate binary phase diagrams, watch heat diffuse through a solid, and observe polymer chains writhing in Brownian motion.
