Nobel Prize in Physics

*The Science of Light*

*From Galileo’s Telescope to Quantum Physics*

Light has fascinated mankind since the dawn of time. Elucidating its properties over the centuries has been an adventure intimately linked with the birth and development of modern science; it has led, after many surprising twists, to the theories of relativity and quantum physics which have profoundly changed our view of the world at the microscopic and cosmic scales alike. Placing his own career in a rich lineage of scientific discovery, Nobel Prize–winning physicist Serge Haroche offers a literally enlightening account of what we know about light today, how we learned it, and how that knowledge has led to countless inventions that have revolutionized daily life.

From Galileo and Newton to Einstein and Feynman, from early measurements of the speed of light to cutting-edge work on quantum entanglement, Haroche takes a detailed and personal look at light’s role in how we see and understand the universe. *The Science of Light* is at once a colorful history of scientific inquiry and a passionate defense of “blue sky research”—investigations conducted not in pursuit of a particular goal, but out of curiosity and faith that today’s abstract discoveries may well power tomorrow’s most incredible possibilities.

**A uniquely captivating book about the thrill of discovery.**
