A new hyper-realistic computer simulation of underwater bubble rings—the kind often created by scuba divers—may shed light on the mathematics and forces that govern such phenomena. ”When we make these abstractions, we still want to capture some fundamental truth about the universe,” says Peter Schröder, the Shaler Arthur Hanisch Professor of Computer Science and Applied and Computational Mathematics, whose team built the simulation. ”What drives me is finding these beautiful descriptions of something that looks terribly complicated but can be reduced to a few mathematical key concepts. Then the rest just follows from there.”
