“What counts, I found, is not what you cover, but what you uncover. Covering subjects in a class can be a boring exercise, and students feel it. Uncovering the laws of physics and making them see through the equations, on the other hand, demonstrates the process of discovery, with all its newness and excitement, and students love being part of it.”
“why on earth should you generate current in that coil? It wasn’t clear at first what the importance of this discovery was. Soon afterward, the story goes, a dubious politician asked Faraday if his discovery had any practical value, and Faraday is supposed to have responded,”
“My purpose in the classroom, and the main reason I’ve written this book, is to translate the truly astounding, groundbreaking, sometimes even revolutionary discoveries of my fellow physicists into concepts and language intelligent, curious laypeople can really get hold of—to make a bridge between the world of professional scientists and your world. Too many of us seem to prefer talking only to our peers and make it awfully difficult for most people—even those who really want to understand science—to enter our world.”
“of glass and put a magnet underneath, get ready for some remarkable results—a lot more interesting”
“The characteristic sounds of a trumpet, oboe, banjo, piano, or violin are due to the distinct cocktail of harmonic frequencies that each instrument produces. I love the image of an invisible cosmic bartender, expert in creating hundreds of different harmonic cocktails, who can serve up a banjo to this customer, a kettledrum to the next, and an erhu or a trombone to the one after that”
“How do I love thee? Let me count the ways.
I love thee to the depth and breadth and height
My soul can reach, when feeling out of sight
For the ends of being and ideal grace.
I love thee to the level of every day's
Most quiet need, by sun and candle-light.
I love thee freely, as men strive for right.
I love thee purely, as they turn from praise.
I love thee with the passion put to use
In my old griefs, and with my childhood's faith.
I love thee with a love I seemed to lose
With my lost saints. I love thee with the breath,
Smiles, tears, of all my life; and, if God choose,
I shall but love thee better after death.”
“It's not what you project... it's what you don't show.”
“I realize that even through the hard times I’m sure we’ll face, I’ll never be able to walk away from her. -Micha”
“I’m not saying it couldn’t eventually lead to more, but right now I feel pretty broken and I’m not really sure there are enough pieces lying around to put me back together.”
“He turned to her. “Didn’t you see the lightning strike the steeple?”
She recovered with a sip of tea, then smiled sweetly. “I was listening too devotedly to the sermon.”
“Claptrap last week,” Lady D announced. “I think the priest is getting old.”
Gareth opened his mouth, but before he could say a word, his grandmother’s cane swung around in a remarkably steady horizontal arc. “Don’t,” she warned, “make a comment beginning with the words, ‘Coming from you…’”
“I wouldn’t dream of it,” he demurred.
“Of course you would,” she stated. “You wouldn’t be my grandson if you wouldn’t.” She turned to Hyacinth. “Don’t you agree?”
To her credit, Hyacinth folded her hands in her lap and said, “Surely there is no right answer to that question.”
“Smart girl,” Lady D said approvingly.
“I learn from the master.”
Lady Danbury beamed.”
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.
