“We are made of the same stardust of which all things are made, and when we are immersed in suffering or when we are experiencing intense joy we are being nothing other than what we can’t help but be: a part of our world.”
Carlo Rovelli, Seven Brief Lessons on Physics
“In his youth Albert Einstein spent a year loafing aimlessly. You don't get anywhere by not 'wasting' time- something, unfortunately, that the parents of teenagers tend frequently to forget.”
Carlo Rovelli, Seven Brief Lessons on Physics
“Genius hesitates.”
Carlo Rovelli, Seven Brief Lessons on Physics
“Here, on the edge of what we know, in contact with the ocean of the unknown, shines the mystery and beauty of the world. And it’s breathtaking.”
Carlo Rovelli, Seven Brief Lessons on Physics
“We are perhaps the only species on Earth to be conscious of the inevitability of our individual mortality. I fear that soon we shall also have to become the only species that will knowingly watch the coming of its own collective demise, or at least the demise of its civilization.”
Carlo Rovelli, Seven Brief Lessons on Physics
“Ever since we discovered that Earth is round and turns like a mad spinning-top, we have understood that reality is not as it appears to us.”
Carlo Rovelli, Seven Brief Lessons on Physics
“There are frontiers where we are learning, and our desire for knowledge burns. They are in the most minute reaches of the fabric of space, at the origins of the cosmos, in the nature of time, in the phenomenon of black holes, and in the workings of our own thought processes. 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.”
Carlo Rovelli, Seven Brief Lessons on Physics
“We are made up of the same atoms and the same light signals as are exchanged between pine trees in the mountains and stars in the galaxies.”
Carlo Rovelli, Seven Brief Lessons on Physics
“Quantum mechanics and experiments with particles have taught us that the world is a continuous, restless swarming of things, a continuous coming to light and disappearance of ephemeral entities. A set of vibrations, as in the switched-on hippie world of the 1960s. A world of happenings, not of things. The”
Carlo Rovelli, Seven Brief Lessons on Physics
“Compare ‘now’ with ‘here’. ‘Here’ designates the place where a speaker is: for two different people ‘here’ points to two different places. Consequently ‘here’ is a word the meaning of which depends on where it is spoken. The technical term for this kind of utterance is ‘indexical’. ‘Now’ also points to the instant in which the word is uttered and is also classed as ‘indexical’. But no one would dream of saying that things ‘here’ exist, whereas things that are not ‘here’ do not exist. So then why do we say that things that are 'now' exist and that everything else doesn't?”
Carlo Rovelli, Seven Brief Lessons on Physics
“It is hardly surprising that there are more things in heaven and earth, dear reader, than have been dreamed of in our philosophy - or in our physics.”
Carlo Rovelli, Seven Brief Lessons on Physics
“What are we, in this boundless and glowing world?”
Carlo Rovelli, Seven Brief Lessons on Physics
“When Einstein died, his greatest rival, Bohr, found for him words of moving admiration. When a few years later Bohr in turn died, someone took a photograph of the blackboard in his study. There’s a drawing on it. A drawing of the ‘light-filled box’ in Einstein’s thought experiment. To the very last, the desire to challenge oneself and understand more. And to the very last: doubt”
Carlo Rovelli, Seven Brief Lessons on Physics
“Once again, the world seems to be less about objects than about interactive relationships.”
Carlo Rovelli, Seven Brief Lessons on Physics
“When we talk about the big bang or the fabric of space, what we are doing is not a continuation of the free and fantastic stories that humans have told nightly around campfires for hundreds of thousands of years. It is the continuation of something else: of the gaze of those same men in the first light of day looking at tracks left by antelope in the dust of the savannah - scrutinising and deducting from the details of reality in order to pursue something that we can't see directly but can follow the traces of. In the awareness that we can always be wrong, and therefore ready at any moment to change direction if a new track appears; but knowing also that if we are good enough we will get it right and will find what we are seeking. That is the nature of science.”
Carlo Rovelli, Seven Brief Lessons on Physics
“Nature is our home, and in nature we are at home. This strange, multicoloured and astonishing world which we explore – where space is granular, time does not exist, and things are nowhere – is not something that estranges us from our true selves, for this is only what our natural curiosity reveals to us about the place of our dwelling. About the stuff of which we ourselves are made.”
Carlo Rovelli, Seven Brief Lessons on Physics
“we are all born from the same celestial seed; all of us have the same father, from which the earth, the mother who feeds us, receives clear drops of rain, producing from them bright wheat and lush trees, and the human race, and the species of beasts, offering up the foods with which all bodies are nourished, to lead a sweet life and generate offspring”
Carlo Rovelli, Seven Brief Lessons on Physics
“To trust immediate intuitions rather than collective examination that is rational, careful, and intelligent is not wisdom: it is the presumption of an old man who refuses to believe that the great world outside his village is any different from the one that he has always known. As”
Carlo Rovelli, Seven Brief Lessons on Physics
“Life on Earth gives only a small taste of what can happen in the universe.”
Carlo Rovelli, Seven Brief Lessons on Physics
“Le equazioni della meccanica quantistica e le loro conseguenze vengono usate quotidianamente da fisici, ingegneri, chimici e biologi, nei campi più svariati. Sono utilissime per tutta la tecnologia contemporanea. Non ci sarebbero i transistor senza la meccanica quantistica. Eppure restano misteriose: non descrivono cosa succede a un sistema fisico, ma solo come un sistema fisico viene percepito da un altro sistema fisico. Che significa? Significa che la realtà essenziale di un sistema è indescrivibile? Significa solo che manca un pezzo alla storia? O significa, come a me sembra, che dobbiamo accettare l’idea che la realtà sia solo interazione?”
Carlo Rovelli, Sette brevi lezioni di fisica
“Here, in the vanguard, beyond the borders of knowledge, science becomes even more beautiful—incandescent in the forge of nascent ideas, of intuitions, of attempts. Of roads taken and then abandoned, of enthusiasms. In the effort to imagine what has not yet been imagined. Twenty”
Carlo Rovelli, Seven Brief Lessons on Physics
“We are made of the same stardust of which all things are made, and when we are immersed in suffering or when we are experiencing intense joy, we are being nothing other than what we can’t help but be: a part of our world.”
Carlo Rovelli, Seven Brief Lessons on Physics
“All things are continually interacting with each other, and in doing so each bears the traces of that with which it has interacted: and in this sense all things continuously exchange information about each other.”
Carlo Rovelli, Seven Brief Lessons on Physics
“When we talk about the big bang or the fabric of space, what we are doing is not a continuation of the free and fantastic stories that humans have told nightly around campfires for hundreds of thousands of years. It is the continuation of something else: of the gaze of those same men in the first light of day looking at tracks left by antelope in the dust of the savannah—scrutinizing and deducting from the details of reality in order to pursue something that we can’t see directly but can follow the traces of. In the awareness that we can always be wrong, and therefore ready at any moment to change direction if a new track appears; but knowing also that if we are good enough we will get it right and will find what we are seeking. This is the nature of science.

The confusion between these two diverse human activities—inventing stories and following traces in order to find something—is the origin of the incomprehension and distrust of science shown by a significant part of our contemporary culture. The separation is a subtle one: the antelope hunted at dawn is not far removed from the antelope deity in that night’s storytelling.

The border is porous. Myths nourish science, and science nourishes myth. But the value of knowledge remains. If we find the antelope, we can eat.”
Carlo Rovelli, Seven Brief Lessons on Physics
“che significa che siamo liberi di prendere delle decisioni, se il nostro comportamento non fa che seguire le leggi della natura?”
Carlo Rovelli, Sette brevi lezioni di fisica
“To the very last, the desire to challenge oneself and understand more. And to the very last: doubt.”
Carlo Rovelli, Seven Brief Lessons on Physics
“A university student attending lectures on general relativity i the morning and others on quantum mechanics in the afternoon might be forgiven for thinking that his professors are fools, or have neglected to communicate with each other for at least a century.”
Carlo Rovelli, Seven Brief Lessons on Physics
“We not only learn, but we also learn to gradually change our conceptual framework and to adapt it to what we learn.”
Carlo Rovelli, Seven Brief Lessons on Physics
“Life is precious to us because it is ephemeral.”
Carlo Rovelli, Seven Brief Lessons on Physics
“In quantum mechanics no object has a definite position, except when colliding headlong with something else.”
Carlo Rovelli, Seven Brief Lessons on Physics
