Art Friday by Michael: Eigenstate
Continuing Michael’s interest in scientific visualisation, this piece represents branching states of a quantum-physical system. It begins with a single element in the centre of the piece, which spawns several child elements—the superposition of several possible states of the system. Every half-second or thereabouts, a child element itself spawns children, and the process iterates, building up a “cloud” of superposed possibilities. On click (or after fifty generations, in this version) a random youngest-child element is selected, and the system collapses to show just the single path that leads from the child to the original—the reified, observed eigenstate. The system then rebuilds after a short pause, evolving into a new complex state.Sounds pretentious? It is, a bit. A fullscreen version of this piece —which collapses the waveform on movement detected by a camera—was an entry in the Macquarie University World Year of Physics Art Prize.
