“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.”

“Every man who is not helping to bring about a better state of affairs for the future is helping to perpetuate the present misery, and is therefore the enemy of his own children. There is no such thing as being neutral: we must either help or hinder.”
― Robert Tressell, quote from The Ragged Trousered Philanthropists
“...the sounds next door served as a kind of trip wire: I seemed to stumble and fall on my face, skinning and bruising myself here and there and scattering my emotional and intellectual possessions. There was no point in pretending that I had not fallen, for when we are stretched out in the dirt we must pick ourselves up and brush off our clothes. This then, in a sense, is what I did, reviewing my considered opinions on marriage, constancy, man's nature, and the importance of love. When I had picked up my possessions and repaired my appearance, I fell asleep.”
― John Cheever, quote from The Stories of John Cheever
“We have loyalty, fidelity, honor--
All three are overrated. The only chance you have to demonstrate any of them is to deny yourself something or someone you desire.”
― Kresley Cole, quote from Kiss of a Demon King
“All opinions are not equal. Some are a very great deal more robust, sophisticated and well supported in logic and argument than others.”
― Douglas Adams, quote from The Salmon of Doubt
“You know how to steer a yacht?" Mr. McIntyre asked Ian worriedly.
"I was born knowing how to steer a yacht," Ian said. Then a stricken look came over his face. "But–do you suppose Jonah prepaid the full amount for renting this? Once my dad hears what Natalie and I did, he'll cancel our credit cards."
"You mean we're...we're poor now?" Natalie gasped.
"Penniless," Ian said grimly.
"Actually," Mr. McIntyre said, "I should have mentioned this before the others left. Grace had an addendum to her will regarding everyone who made it through the gauntlet. There were eight of you–you will all receive double the amount you turned down to get the first clue."
"It was a million dollars originally," Ian said. "So Natalie and I each get two million dollars? I suppose we could live on that."
Natalie beamed.
"That is such a relief!" she said. "Being poor wasn't quite as bad as I thought it would be, but still–"
"You were only poor for about two seconds!" Dan protested, rolling his eyes.”

The Schopenhauer Cur...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.
