Traces how the human image of the world has changed throughout history, demonstrating the evolution of the idea of reality while touching on subjects ranging from the Higgs boson to quantum gravity.

In elegant and accessible prose, Rovelli takes listeners on a wondrous journey from Aristotle to Albert Einstein, from Michael Faraday to the Higgs boson, and from classical physics to his own work in quantum gravity. As he shows how the idea of reality has evolved over time, Rovelli offers listeners a deeper understanding of the theories he introduced so concisely in Seven Brief Lessons on Physics. His evocative explanations invite listeners to imagine, beyond their ever-changing idea of reality, a whole new world that has yet to be discovered.
