“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”
“Early anthropology was not at all seen as art for art’s sake; it was intended to facilitate the colonizer’s work.”
“The girl I was before this trip is dead. I’m worried who will take her place. It frightens me. I’m afraid my bitterness is bigger and will never be contained. I’m not sure I want to meet the new me.”
“If Capitalism improves the economic position all round, it is of secondary importance that it does not raise all to the same level. A social order is not bad simply because it helps one more than the other.”
“A tent was set up as a make shift changing room for the models to do their preparation. Hair and make-up were done within this 12' x 12' fabric enclosure which sprouted electrical cords for hair dryers and electric rollers, necessities for “bouffant” hairdos. I was mesmerized while watching different colored eye shadows, face powders and lipsticks painted onto the females. Seeing glamorous pictures in a glossy magazine was one thing but witnessing first-hand how it was applied was quite another. The hours of preparation that went into preparation for each model included in a photograph stunned me.”
“The Doctor puffed out some air and looked down to the sea. 'A very charming man. I should be more careful of very charming men... At least I don't have that problem with you, Rory.'
'Oi,' said Rory.”
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.
