报告摘要：

A universal energetics hidden within Gibbs' thermodynamics is discovered; the neo-Gibbsian energetics is applicable to large statistical data set. By shifting the current paradigm in statistical physics, it 1) introduces equilibrium as a statistical concept via Legendre-Fenchel duality symmetry between empirical measurements of extensive variables and their conjugates as entropic forces; 2) identifies thermodynamic limit concisely as data ad infinitum rather than N, V → ∞; and 3) formalizes a mesoscopic energetics (k_B ≠ 0) that predates the characterization of systems with fluctuations by information entropy. Duality symmetry breaking captures nonequilibrium with an irreversible thermodynamic potential representing dissipation.

报告人简介：

Dr. Hong Qian earned his bachelor's degree in Astrophysics from Peking University, followed by a Ph.D. in Biochemistry from Washington University in St. Louis. During his doctoral studies, he combined theoretical, experimental, and data analytic approaches to investigate single molecule biophysics, specifically focusing on Fluorescence Correlation Spectroscopy (FCS) and Single-Particle Tracking (SPT). As a postdoctoral researcher, he conducted studies on the thermodynamics and kinetics of protein folding at the University of Oregon and the California Institute of Technology. After a three-year stint in the Department of Biomathematics at the UCLA School of Medicine, Dr. Qian joined the Department of Applied Mathematics at the University of Washington in Seattle in 1997, with an adjunct appointment in the Department of Bioengineering at the university’s School of Medicine. He progressed through the academic ranks as Assistant Professor, Associate Professor, and Professor, and was appointed as the Olga Jung Wan Endowed Professor. In 2010, he was elected a Fellow of the American Physical Society. Additionally, Dr. Qian has served associate editor of several journals published by the Society for Industrial and Applied Mathematics (SIAM) and has been members of the editorial committees of multiple journals in the fields of biophysical chemistry, systems biology, and quantitative biology. In 2011, he co-founded the Gordon Research Conference on Stochastic Physics in Biology with Professor Ken A. Dill. He Joined Westlake University in October, 2025, and is currently Chair Professor of Interdisciplinary Studies.
