Nine domains of science, transformed by the ability to compute. Follow how the Metropolis algorithm — invented to simulate hydrogen bomb cores — propagated into molecular dynamics, protein folding, and climate models. Or how aperture synthesis, first computed on Cambridge's EDSAC 2 in 1960, led to the first image of a black hole in 2019. Or how WWII codebreaking at Bletchley Park became NSA supercomputing, DES, RSA, and finally post-quantum cryptography. Hover any node for details; cross-column edges show where methods jumped between fields.
