The author of the new book "How to Build a Universe" will give a talk at the CERN Library:

What is the universe made of, and how do we know? This is the central question of my upcoming book, "How to Build a Universe (Theoretically Speaking)." In this talk, I'll discuss some of the most intriguing connections between particle physics and cosmology and the challenges of translating complex, mathematical theories to the general public.

The event will be followed by a Q&A. The book will be published in March 2027.
