“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”
“Who'll hold families together, if everybody has to live? Living is a compromise, between doing what you want and doing what other people want.”
“Summer was a long hot dream.”
“I'll talk to Mortimer and see what he thinks, and then get back to you tomorrow. In the meantime, you should really get to sleep and get those shared dreams going."
Cale grimaced at the suggestion, and reminded him, "She has a splitting headache, Bricker."
"I thought that was a married woman's complaint?" Bricker responded quickly, and then laughed at his own joke as he hung up.”
“Greg was a supernice guy and a good tenant.”
“I met him only once, but he seemed pretty cool,” I said. “Of course, the neighbor across the street was convinced he was up to no good.”
“Oh, my God, that racist bitch? I swear, I wanted to rent the place out to a black Jewish gay couple just to piss her off, but then I figured it wouldn’t be fair to the black Jewish gay couple.”
“The first thing I noticed as we exited the theater was how much colder it was than when we arrived. The second thing I noticed was how slick the sidewalk was. I didn’t notice that it was snowing until I was sprawled on the pavement.
“Scout! Are you okay?” Alex’s face loomed above me.
“I think I broke my butt.”
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.
