Preface to the Special Collection in Honor of Freeman Dyson.

This document is a preface to a special collection in honor of Freeman Dyson, a renowned mathematician and theoretical physicist. Dyson made significant contributions to various fields, including quantum electrodynamics, statistical mechanics, many-body quantum mechanics, stability of matter, quantum entropy, trace inequalities, and random matrix theory. The collection includes papers related to these topics, written by collaborators and former colleagues of Dyson. Dyson received numerous prestigious prizes and awards throughout his career. The preface also mentions a paper in the collection that applies mathematics to neuroscience, which Dyson would have appreciated. [Extracted from the article]
