Quotes from Relativity: The Special and the General Theory

“Dear Habicht, / Such a solemn air of silence has descended between us that I almost feel as if I am committing a sacrilege when I break it now with some inconsequential babble... / What are you up to, you frozen whale, you smoked, dried, canned piece of soul...?”
― Albert Einstein, quote from Relativity: The Special and the General Theory

“If you've never done anything wrong it's probably because you have never tried anything new.”
― Albert Einstein, quote from Relativity: The Special and the General Theory

“An observer who is sitting eccentrically on the disc K' is sensible of a force which acts outwards in a radial direction, and which would be interpreted as an effect of inertia (centrifugal force) by an observer who was at rest with respect to the original reference-body K. But the observer on the disc may regard his disc as a reference body which is “at rest”; on the basis of the general principle of relativity he is justified in doing this. The force acting on himself, and in fact on all other bodies which are at rest relative to the disc, he regards as the effect of a gravitational field.”
― Albert Einstein, quote from Relativity: The Special and the General Theory

“result: every description of events in space involves the use of a rigid body to which such events have to be referred. The resulting relationship takes for granted that the laws of Euclidean geometry hold for ‘distances’, the ‘distance’ being represented physically by means of the convention of two marks on a rigid body.”
― Albert Einstein, quote from Relativity: The Special and the General Theory

“of the actual objects of physical reality. Physical objects are not in space, but these objects are spatially extended.”
― Albert Einstein, quote from Relativity: The Special and the General Theory

“if, relative to K, K’ is a uniformly moving co-ordinate system devoid of rotation, then natural phenomena run their course with respect to K’ according to exactly the same general laws as with respect to K. This statement is called the Principle of Relativity (in the restricted sense).”
― Albert Einstein, quote from Relativity: The Special and the General Theory

“I was also built from delusional optimism and folly.”
― A.S. King, quote from Please Ignore Vera Dietz

“Иногда мне хочется совершить самый нелепый поступок. Сделать что-нибудь такое, что разобьет эту стеклянную клетку. Кинуться куда-нибудь, не знаю куда.”
― Erich Maria Remarque, quote from Heaven Has No Favorites

“They all seem infected with a vivaciousness that isn't common in our compound, and there are more smiles on their faces than I've ever seen at once. And yet as I watch them, I feel more intensely than ever the knowledge that I'm not one of them. For these moral humans, birthdays are a kind of countdown to the end, the ticking clock of a dwindling life. For me, birthdays are notches on an infinite timeline. Will I grow tired of parties one day? Will my birthday become meaningless? I imagine myself centuries from now, maybe at my three-hundredth birthday, looking all the way back to my seventeenth. How will I possibly be happy, remembering the light in my mother's eyes? The swiftness of Uncle Antonio's steps as he dances? The way my father stands on edge of the courtyard, smiling in that vague, absent way of his?

The scene shifts and blues in my imagination. As if brushed away by some invisible broom, these people whom I've known my entire life disappear. The courtyard is empty, bare, covered in decaying leaves. I imagine Little Cam deserted, with everyone dead and gone and only me left in the shadows.

Forever.”
― Jessica Khoury, quote from Origin

“Men who are certain of everything—well perhaps they're not men at all.”
― Mark Lawrence, quote from Emperor of Thorns

“But she could not think of any herb that would heal his broken heart.”
― Erin Hunter, quote from Starlight

About BookQuoters

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.
