The Lightness of Being: Mass, Ether, and the Unification of Forces

Frank Wilczek

Physics

Wilczek explains how modern physics reconceives empty space as a dynamic medium—a 'Grid'—from which mass and matter emerge as patterns of disturbance. He explores the origin of mass, the role of quantum fields, and the prospects for a unified theory of nature's forces. The book presents these ideas for a general audience while drawing on the author's own work in quantum chromodynamics.
