What is the book about?
“Seven Brief Lessons on Physics” is written by Carlo Rovelli, an Italian theoretical physicist and one of the founders of loop quantum gravity theory. Simon Carnell and Erica Segre translated this into English from the original Italian.
This book has been written for those who know little or nothing about modern physics. It provides a rapid overview of the latest happenings in physics in a concise manner.
What does this book cover?
“Seven Brief Lessons on Physics” is a short book, weighing at less than a 100 pages. But, in this short book, Carlo Rovelli introduces the following the topics to us.
- General Relativity, where we understand that space and gravity are one and the same.
- Quantum Mechanics, where nothing exists except when needed
- Astrophysics, where the architecture of the cosmos is explained
- Elementary Particles, where we learn about the Standard Model and its limitations
- Loop Quantum Gravity, which aims to solve the contradictions between General Relativity and Quantum Mechanics
- Heat and Black Holes, where we learn that the fundamental phenomenon that distinguishes the future from the past is the fact that heat passes from hot to cold objects
Each of these topics has a chapter devoted to it. The last chapter is an introspection of the self and our relationship to reality.
What did I like?
The main takeaway from this book is its clear and crisp explanation of complex topics. Carlo Rovelli and the translators have done a brilliant job in making abstruse topics, which are mind-bending, comprehensible to the general public.
In fact, I will go out on a limb and say that my understanding of topics, which I thought I knew, has become better after reading this book. For example, the fact that the passage of time is basically determined by entropy is an intuitive leap that I never quite made before.
The other aspect of this book was its coverage of the latest topics in physics. I have said before that we need to be taught the latest developments in STEM in school itself and not in college. This book does a great job of filling the gap.
The chapter on astrophysics deserves a special mention here. I have heard, read and seen various depictions of the Universe. But, nowhere, has it been explained in such a unique fashion as in this chapter. Carlo Rovelli uses images to show us how our understanding of the structure of the Universe has changed starting from 5000 BC till today. It is simple in concept but powerful in its impact.
What did I not like?
I did not want this book to end.
“Seven Brief Lessons in Physics” is a brilliant book that has surpassed its goals of bringing the latest science to the general public.
I strongly recommend this book.
