From the Preface
These lessons were written for those who know little or nothing about modern science. Together they provide a rapid overview of the most fascinating aspects of the great revolution that has occurred in physics in the twentieth and twenty-first centuries, and of the questions and mysteries that this revolution has opened up. Because science shows us how to better understand the world, but it also reveals to us just how vast is the extent of what is still not known.
The first lesson is dedicated to Albert Einstein's general theory of relativity, the "most beautiful of theories." The second to quantum mechanics, where the most baffling aspects of modern physics lurk. The third is dedicated to the cosmos: the architecture of the universe that we inhabit; the fourth to its elementary particles. The fifth deals with quantum gravity: the attempts that are under way to construct a synthesis of the major discoveries of the twentieth century. The sixth is on probability and the heat of black holes. The final section of thebook returns to ourselves and asks how it is possible to think about our existence in the light of the strange world described by physics.

A simplified introduction to physics and reality for a non-cognoscente
By Rama Rao
Theoretical physicist Carlo Rovelli has condensed physics ideas into this 78 pages book. This work is the result of a series of articles published in an Italian newspaper. Building basic concepts to comprehend the nature of reality has not been simple for theoretical physicists, but the author has spared the narratives for leaner and lucid descriptions in the hopes that these ideas stir up some interest among readers. There is no math and no heavy discussion of relativity or quantum physics. String physics is not included in this discussion. This is certainly a good way to bring modern physics for general readers. This reminds me of Nobel Laureate Richard Feynman’s “Six Easy Pieces: Essentials of Physics Explained.” This book has appeared in many versions and captured the minds of readers in theoretical physics. But Rovelli covers only seven topics that include relativity, quantum physics, particle physics and black holes.
The author is one of the inventors of loop quantum gravity which says that space is not continuous but it is made of grains, significantly smaller than an electron, and they are linked to each other forming a network. Quantum gravity essentially refers to quantum properties of space-time and not the quantum behavior of matter in spacetime. But the author has not discussed loop quantum gravity theory in any depth in this book.
The author muses on human existence and our perception of physical reality. It is a song of god in which matter (energy) behave in spacetime in a certain way, and this guided by a set of physical laws. The Newtonian physics, relativistic physics, quantum physics and thermodynamics somehow connect with each other to create the nature of reality. But we are further away in comprehending it and Carlo Rovelli understands this better than other physicists.

Brilliant and elegant homilies on physics, the nature of scientific endeavor, and being human
By John K. Gayley
This is indeed, a very brief book of very brief lessons or chapters, and it is intriguing, elusive, seductive and ultimately humbling all at once. I’ll need to read it again several times over. The easy elegance and poetry of the writing deceptively masks a whole world of things being described, and the broader, better lessons aren’t really about physics at all.
Hitherto, my last experience with physics was a 2nd semester senior class in high school when, (having been accepted to university), I temporarily lost patience for absorbing further conceptual learning. I did, however, have ample capacity for sniggering at the nerds in the class who were capable of using physics concepts, 3 paper clips and assorted other parts to construct a functioning radio.
I read about this book in the Economist. I bought this book, in part, to atone for my high school sins, and also to finally overcome my phobia of the general theory of relativity. I also wanted it as a quick way to get refreshed on key physics concepts in "bite size" bits, suitable for impressing people at parties. (Because To be impressive at parties, everyone really should have their own "elevator speech" ready on the meaning of the theory of relativity, right?)
This book gave me both more—and less—than I bargained for. I still don’t have my elevator speeches on topics such as relativity, quantum mechanics, thermodynamics or black holes; the lessons are indeed elegant but without sufficient detail to fully master the topics at hand. In fact, if anything, the simplicity and elegance of the book have made me feel even stupider than when I started…”if this Italian Physics professor can describe these things so simply and elegantly, I really must be a half-wit, because I’m still mystified.” (Memo to self: avoid elevators or parties for now.)
However, even in its brevity the book gives a good deal more. There is the enthusiasm and excitement that imbues the (even brief) descriptions of physics and related concepts. I came away with a genuine desire to go after these topics in successively greater levels of detail, in order, finally, to conquer them. At the very least I see another series of sessions with a famous Stephen Hawking book in my future.
The specific physics topics are only the most obvious level in this slim volume. It also touches both implicitly and explicitly on the nature of scientific enquiry, insights into the current bleeding edge physics theories and how they’re developed, and (lastly) how scientists think. To read about this in such effective but matter-of-fact tones was extremely enlightening.
The 7th and final lesson in the book is one which I’ve read three times already, because its so marvelous….a homily by a thoughtful soul on the complexities of the universe, the perceptions and complexities of humans inhabiting their small place in it, and a heartfelt wonder about the ongoing discoveries we have in front of us. The final chapter, “ourselves” really is lovely, and could easily stand alone, with or without the preceding 6 chapters.
I’ve given this five stars. Although it didn’t take me where I thought I wanted to go, it took me someplace else, and much better.

A beautiful and poignant meditation on the laws of physics and our place in the cosmos
By Ash Jogalekar
Every once in a while it's a good idea to stand back from the daily necessities of our lives and look back and marvel at what we as human beings have accomplished in our understanding of ourselves and our universe. In very few instances is this wonder more apparent than in an appreciation of the discoveries that physics has made regarding space and time.
In this short and highly readable book, Italian physicist Carlo Rovelli leads us through a tour of what he thinks are seven of the foremost ideas (or "lessons') in physics. These are ideas which have not just furthered our understanding of our material world but which have also expanded our consciousness and connected us to our origins and future. Rovelli’s writing is often poignant and beautiful, simple and without frills and from the heart, and I would be lying if I said the experience wasn't uplifting. Personally I would have included an extra eighth lesson on chaos theory and complexity since I think those are going to be key scientific issues in the 21st century. Also, there is little new per se in here which would not be familiar to physics aficionados. But as it stands Rovelli's offering is a marvelous feast which should ignite a renewed sense of inspiration regarding the reach and beauty of science even in hardened veterans.
The first lesson is about Einstein's general theory of relativity which saw yet another towering validation this year with the discovery of gravitational waves. The Russian physicist Lev Landau called it the "most beautiful theory" and I would say there would be few contenders for that title. The basic equation of the theory fits on a napkin, and the essentials of the framework are both startling and elegant. As Rovelli explains, Einstein's major breakthrough was to realize that Newton's gravitational field is not a field at all but is spacetime itself. That one insight suddenly elevated all of physics to a completely new level and it opened up previously unimaginable vistas - black holes, neutron stars, radio astronomy, the Big Bang - to deep exploration. Here's Rovelli on the essential craziness of Einstein's equation: "Within this equation there is a teeming universe. And here the magical richness of the theory opens up into a phantasmagorical succession of predictions that resemble the delirious ravings of a madman, but which have all turned out to be true."
The second lesson concerns the other big revolution of twentieth century physics - quantum mechanics. Relativity is astonishing but its basic tenets are easy to understand. In contrast, even the basic tenets of quantum theory - wave particle duality, entanglement, the uncertainty principle - have left even the theory's great founders befuddled. Quantum mechanics is unique in the history of science as a theory which is spectacularly successful in its practical applications while at the same time continuing to be virtually impenetrable in its philosophical implications. It opened up vast new areas of modern life to understanding; without it computers, chemistry, electronics and molecular biology would be inconceivable. And yet the sheer weirdness of its laws continues to defy every commonsense expectation. Rovelli zeroes in on one of the essential qualities of quantum mechanics when he says that its laws "do not describe what happens to a physical system but only how one physical system affects another". I find it interesting that the same interactions which lie at the heart of quantum theory also underlie the science of emergent complex systems like the weather, the stock market, biochemical networks and social networks.
The third chapter talks about the Big Bang theory and the architecture of the cosmos. Rovelli wrote just before the discovery of gravitational waves otherwise he would have included them in his discussion but he talks about many other wonders revealed by Einstein's theory combined with many of the tools of modern physics such as radio telescopes and particle detectors. The culmination of applying relativity to the universe must surely be the discovery of the accelerated expansion of the universe, although the presence of what we call "dark matter" leaves something to be desired.
The fourth lesson tells us how the findings of quantum mechanics led to an explosion of understanding of the building blocks of the cosmos in the postwar years. Quarks and electrons, Higgs bosons and neutrinos all make important appearances in this story. The culmination of all this progress was the Standard Model of particle physics, essentially a kind of periodic table which lists all known particles and their properties. And yet unlike general relativity the Standard Model is incomplete. Many of the particles' parameters are poorly understood, and the model itself is incompatible with general relativity. In addition there are ugly infinities arising in the theoretical treatment of all those particles which have to be tamed by artificially imposed mathematical order. These deficiencies make the Standard Model very much of a model. It is in the Standard Model that we start to glimpse the first troubling signs of how much more we have to discover in fundamental physics. But in trouble lies opportunity and glory, and in one sense the Standard Model only points to the bounty of undiscovered delights which must surely lie ahead.
The fifth lesson tackles one of the greatest scientific facing science, the marriage of general relativity with quantum mechanics; a marriage which as of now seems to end in violent, unholy divorce every time we attempt it. Interestingly there is not a word about string theory, probably because Rovelli himself works on a rival theory called loop quantum gravity. There is a capsule description of the theory which emphasizes again the fact that the framework is less about objects themselves and more about their interconnections. In this case the connections are between tiny quanta of space - which are themselves space.
The sixth lesson takes us on a journey into one of the most exciting frontiers of modern physics: the union of thermodynamics, quantum mechanics and relativity. This union is wondrous and critical because it can help us understand perhaps the deepest question we can ponder: the fact that time seems to flow only in one direction. As Rovelli explains, the arrow of time seems to be inextricably linked with the flow of heat. The second law of thermodynamics and its postulated increase of entropy tracks with the forward arrow of time, although on an individual particle level this arrow is reversible. Figuring out these conundrums of time and thermodynamics will undoubtedly take us into some very novel territory. In this context Stephen Hawking's discovery of radiation emanating from black holes is surely a promising springboard. Time, thermodynamics, quantum mechanics, relativity, statistics; it's all here, and it's all tantalizing.
The seventh lesson ties it all up together as Rovelli talks about the ultimate entity that allows us to figure all this out - the human brain. He ponders the delectable paradox that an entity which is composed of particles and fields and quanta can also decipher its own mysteries. Understanding this self-recursive extrapolation should keep us occupied for as long into the future as we can imagine, and it's also what should make us cherish our unique existence as sentient beings on this planet. And yet, as unique as we are, Rovelli reminds us in closing that our lowly origins from elemental life forms and the ordinariness of our planet, our solar system and our galaxy should not blind us to what might be the greatest lesson of all: humility and wonder.
"Here, on the edge of what we know, in contact with the ocean of the unknown, shines the mystery and the beauty of the world. And it's breathtaking".
