Understanding the incipient stages of phase change in superheated fluids - and their subsequent evolution - remains a fundamental challenge in thermal-fluids science. By coupling fluctuating hydrodynamics with rare-event techniques we bridge the gap between stochastic microscopic nucleation and deterministic macroscopic bubble dynamics, revealing previously inaccessible physics of the boiling process. This research offers a new foundation for the design of next-generation heat transfer systems and more accurate multiscale boiling models.
