The recap
The theoretical physicist Carlo Rovelli set out to explain the biggest ideas in modern physics in a handful of short essays, and the result is a book you can finish in an afternoon. The lessons travel from Einstein's general relativity, which Rovelli calls the most beautiful of theories, to the strange rules of quantum mechanics, the architecture of the cosmos, the zoo of elementary particles, the unfinished search for a theory that unites gravity with the quantum world, and the deep puzzle of heat and time. A final chapter turns the lens back on us, asking what it means for human beings, with all our curiosity and feeling, to be part of the world physics describes. Rovelli writes like a lyrical essayist rather than a textbook author, reaching for images and wonder instead of equations. It is a perfect first step for readers who have always wanted to know what physicists are talking about but felt shut out by the maths.
Why read it
For curious readers who want a short, beautiful way into Einstein, quantum theory and the nature of time without any equations.
Fun facts
- 01
The book grew out of articles Rovelli wrote for the Sunday supplement of the Italian newspaper Il Sole 24 Ore, which the physicist Giuseppe Trautteur then proposed to the publisher Adelphi.
- 02
Adelphi published it in October 2014 and it sold more than 300,000 copies in Italy within about 14 months; the English translation by Simon Carnell and Erica Segre followed in 2015.
- 03
Rovelli is one of the founders of loop quantum gravity, an approach to reconciling general relativity with quantum mechanics.
- 04
He explores the same themes at greater length in Reality Is Not What It Seems and The Order of Time (2018).
