“Truth is eternal. Knowledge is changeable. It is disastrous to confuse them.”
― Madeleine L'Engle, quote from An Acceptable Time
“My dear, I'm seldom sure of anything. Life at best is a precarious business, and we aren't told that difficult or painful things won't happen, just that it matters. It matters not just to us but to the entire universe.”
― Madeleine L'Engle, quote from An Acceptable Time
“But if I knew everything, there would be no wonder, because what I believe in is far more than I know.”

“My dear, I'm seldom sure of anything. Life at best is a precarious business...”

“That was the big cure-all with these people, wasn’t it? Girl got you down? Get laid. No money? Get laid. Armageddon ensuing? Get laid a lot.”
― Cherrie Lynn, quote from Rock Me
“Newton had invented the calculus, which was expressed in the language of "differential equations," which describe how objects smoothly undergo infinitesimal changes in space and time. The motion of ocean waves, fluids, gases, and cannon balls could all be expressed in the language of differential equations. Maxwell set out with a clear goal, to express the revolutionary findings of Faraday and his force fields through precise differential equations.
Maxwell began with Faraday's discovery that electric fields could turn into magnetic fields and vice versa. He took Faraday's depictions of force fields and rewrote them in the precise language of differential equations, producing one of the most important series of equations in modern science. They are a series of eight fierce-looking differential equations. Every physicist and engineer in the world has to sweat over them when mastering electromagnetism in graduate school.
Next, Maxwell asked himself the fateful question: if magnetic fields can turn into electric fields and vice versa, what happens if they are constantly turning into each other in a never-ending pattern? Maxwell found that these electric-magnetic fields would create a wave, much like an ocean wave. To his astonishment, he calculated the speed of these waves and found it to be the speed of light! In 1864, upon discovering this fact, he wrote prophetically: "This velocity is so nearly that of light that it seems we have strong reason to conclude that light itself...is an electromagnetic disturbance.”

“That’s when you become old, when you stop being fascinated by things, when you stop wanting to learn and explore.”

“You never have perfect knowledge in combat, gentlemen. It’s what we call the fog of war. You can either sit around worrying what’s real and what’s not, or you can realize the enemy hasn’t got a clue either and fire off a few rounds of psychology. A truly great army is one that only has to rattle its saber to win a war.”

Fading AwayBookQuoters 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.
