“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.”

“Robin didn't like that idea very much-Jules spending time with Adam? "I get jealousy too, you know. You used to be in love with him."
Jules turned his head to look at him. "That was before I knew what love really was". He smiled. "When I met you, Robin, God.... I had to redefine everything. You know, there was this country song my mother really liked. It used to annoy me, I was in my technopop phase, but lately I just... I find myself thinking about the lyrics all the time. That was a river, this is the ocean.... I thought I loved Adam, and I did, but... it wasn't even close to this incredible ocean that I feel for you".”

“Not my manner of thinking but the manner of thinking of others has been the source of my unhappiness.”

“And if he had lived, he would have been tall and strong, weak and wise. He would have needed me, and he would have pushed me away.”
― Anne Frasier, quote from Hush
“What would have happened had he not been killed? He would certainly have had a rocky road to the nomination. The power of the Johnson administration and much of the party establishment was behind Humphrey. Still, the dynamism was behind Kennedy, and he might well have swept the convention. If nominated, he would most probably have beaten the Republican candidate, Richard M. Nixon. Individuals do make a difference to history. A Robert Kennedy presidency would have brought a quick end to American involvement in the Vietnam War. Those thousands of Americans—and many thousands more Vietnamese and Cambodians—who were killed from 1969 to 1973 would have been at home with their families. A Robert Kennedy presidency would have consolidated and extended the achievements of John Kennedy’s New Frontier and Lyndon Johnson’s Great Society. The liberal tide of the 1960s was still running strong enough in 1969 to affect Nixon’s domestic policies. The Environmental Protection Act, the Occupational Safety and Health Act, the Comprehensive Employment and Training Act with its CETA employment program were all enacted under Nixon. If that still fast-flowing tide so influenced a conservative administration, what signal opportunities it would have given a reform president! The confidence that both black and white working-class Americans had in Robert Kennedy would have created the possibility of progress toward racial reconciliation. His appeal to the young might have mitigated some of the under-thirty excesses of the time. And of course the election of Robert Kennedy would have delivered the republic from Watergate, with its attendant subversion of the Constitution and destruction of faith in government. RRK”
― Arthur M. Schlesinger Jr., quote from Robert Kennedy and His Times
“There is no less holiness at this time- as you are reading this- than there was on the day the Red Sea parted, or that day in the 30th year, in the 4th month, on the 5th day of the month as Ezekiel was a captive by the river Cheban, when the heavens opened and he saw visions of god. There is no whit less enlightenment under the tree at the end of your street than there was under Buddha’s bo tree…. In any instant the sacred may wipe you with its finger. In any instant the bush may flare, your feet may rise, or you may see a bunch of souls in trees.”

Mr. Sammler's PlanetBookQuoters 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.
