Quotes from Just Six Numbers: The Deep Forces That Shape the Universe

“The sun has adjusted its structure so that nuclear power is generated in the core, and diffuses outward, at just the rate needed to balance the heat lost from the surface-heat that is the basis for life on Earth.”
― Martin J. Rees, quote from Just Six Numbers: The Deep Forces That Shape the Universe

“Our universe, extending immensely far beyond our present horizon, may itself be just one member of a possibly infinite ensemble. This ‘multiverse’ concept, though speculative, is a natural extension of current cosmological theories, which gain credence because they account for things that we do observe. The physical laws and geometry could be different in other universes, and this offers a new perspective on the seemingly special values that the six numbers take in ours.”
― Martin J. Rees, quote from Just Six Numbers: The Deep Forces That Shape the Universe

“[The fine structure constant] ... defines how firmly atomic nuclei bind together and how all the atoms on Earth were made. Its value controls the power from the Sun and, more sensitively, how stars transmute hydrogen into all the atoms of the periodic table.”
― Martin J. Rees, quote from Just Six Numbers: The Deep Forces That Shape the Universe

“A measure of the strength of a body's gravity is the speed with which a projectile must be fired to escape its grasp. It takes 11.2 kilometers per second to escape from the Earth. This speed is tiny compared with that of light, 300,000 kilometers per second, but it challenges rocket engineers constrained to use chemical fuel, which converts only a billionth of its so-called mass 'rest-mass energy' (Einstein's mc^2) into effective power. The escape velocity from the sun's surface is 600 kilometers per second-still only one fifth of one percent of the speed of light.”
― Martin J. Rees, quote from Just Six Numbers: The Deep Forces That Shape the Universe

“More energy is needed to rise a millimetre above a neutron star's surface than to break completely free of Earth's gravity. A pen dropped from a height of one metre would impact with the energy of a ton of TNT (although the intense gravity on a neutron star's surface would actually, of course, squash any such objects instantly). A projectile would need to attain half the speed of light to escape its gravity; conversely, anything that fell freely onto a neutron star from a great height would impact at more than half the speed of light.”
― Martin J. Rees, quote from Just Six Numbers: The Deep Forces That Shape the Universe

“The Sun contains about a thousand times more mass than Jupiter. If it were cold, gravity would squeeze it a million times denser than an ordinary solid: it would be a 'white dwarf' about the size of the Earth but 330,000 times more massive. But the Sun's core actually has a temperature of fifteen million degrees-thousands of time hotter than its glowing surface, and the pressure of this immensely hot gas 'puffs up' the Sun and holds it in equilibrium.”
― Martin J. Rees, quote from Just Six Numbers: The Deep Forces That Shape the Universe

“We are joint heirs,' I said in a sharp undertone. 'The land will always be partly mine.'
Richard smiled, a smile like midsummer skies. 'I shan't regard it.' He said sweetly. 'And you don't know the law, my clever little cousin. If they commit you to an asylum, you are disinherited at once. Did you not know that, my dear? If you go on with your seeings and your dreamings, you will lose everything.”
― Philippa Gregory, quote from The Favored Child

“The Fates themselves grant us one or two places in our lives where the thread untwists and we can follow either one strand or the other. Better to know when and where those choices will come to us instead of being taken by surprise. “
“Why only one or two?” I asked, thinking of all the moments my life had already accumulated in which I’d chosen to follow a different path than the one most people would expect of me. “Why not say that every day lets me choose my own future?”
The priest chuckled. “What a gift you have for joking, Lady Helen! You know your future. You’ll be Sparta’s queen, living a life blessed by the gods. Your only surprises will be the name of your husband and whether your babies will be sons or daughters. You don’t need to visit the Pythia. But your noble brothers will be heroes, making their own futures; heroes should know what awaits them.”
“He’s right, Helen,” Castor said. “Polydeuces and I should know our fate.”
Castor’s fate? He didn’t need an oracle to discover that; I could tell him exactly what it would be. The young priest’s glib words were better than underground fumes for giving me a vision of what lay in store for both of my brothers: They were going to have their ears filled with flattery, then be persuaded to leave a rich gift at Apollo’s shrine just to hear some poor girl babble riddles while she choked half to death on smoke. Then they’d made another offering just to have Apollo’s priests translate the Pythia’s wild words. If their gifts to the sun god were too extravagant, I could also predict what Father would have to say about it when we got home.”
― Esther M. Friesner, quote from Nobody's Princess

“What began as downsizing went on to wholesale abandonment. Schools closed, libraries and academies shut their doors, professional grammarians and teachers of rhetoric found themselves out of work. There were more important things to worry about than the fate of books.”
― Stephen Greenblatt, quote from The Swerve: How the World Became Modern

“I’m twenty-eight years old and I hate my life. I never have the time or the energy to work out how to change it. On Sundays I trail round a museum to keep warm, or lose myself in a library book, or fiddle with the wireless. But Monday’s already looming. And always I’ve got this panicky feeling inside, because I know I’m getting nowhere, just keeping myself alive. Tacked”
― Michelle Paver, quote from Dark Matter

About BookQuoters

BookQuoters is a community of passionate readers who enjoy sharing the most meaningful, memorable and interesting quotes from great books. As the world communicates more and more via texts, memes and sound bytes, short but profound quotes from books have become more relevant and important. For some of us a quote becomes a mantra, a goal or a philosophy by which we live. For all of us, quotes are a great way to remember a book and to carry with us the author’s best ideas.

We thoughtfully gather quotes from our favorite books, both classic and current, and choose the ones that are most thought-provoking. Each quote represents a book that is interesting, well written and has potential to enhance the reader’s life. We also accept submissions from our visitors and will select the quotes we feel are most appealing to the BookQuoters community.

Founded in 2023, BookQuoters has quickly become a large and vibrant community of people who share an affinity for books. Books are seen by some as a throwback to a previous world; conversely, gleaning the main ideas of a book via a quote or a quick summary is typical of the Information Age but is a habit disdained by some diehard readers. We feel that we have the best of both worlds at BookQuoters; we read books cover-to-cover but offer you some of the highlights. We hope you’ll join us.
