Sonoluminescence is a paradigm of transdisciplinary physics. Low amplitude sound energy entering a fluid spontaneously focuses by 12 orders of magnitude to create a flash of light and a new phase of matter. The degree to which the energy density of a continuous system can concentrate in off-equilibrium motion has not been determined by theory. Additional examples processes that concentrate energy density include: tribo-electrification where the power applied to peel tape is efficiently transduced into a flux of x-ray photons that can expose an image in a few seconds, and ferroelectricity where heating a crystal by 40C generates nuclear fusion in a deuterated environment. The talk concludes with pot-shots at the reductionist approach to physics.
