Perturbation Quotes

“The significance of [the fine-structure constant] goes far beyond atomic physics, however. It is the smallness of 1/137 compared to unity that enables us to treat the coupling between the electromagnetic field and a charged particle such as an electron as a small perturbation, a fact of great computational importance. [Forces of Nature]”

“Contrary to what is generally believed, meaning and sense were never the same thing, meaning shows itself at once, direct, literal, explicit, enclosed in itself, univocal, if you like, while sense cannot stay still, it seethes with second, third and fourth senses, radiating out in different directions that divide and subdivide into branches and branchlets, until they disappear from view, the sense of every word is like a star hurling spring tides out into space, cosmic winds, magnetic perturbations, afflictions.”

“There is no safe investment. To love at all is to be vulnerable. Love anything, and your heart will certainly be wrung and possibly be broken. If you want to make sure of keeping it intact, you must give your heart to no one, not even to an animal. Wrap it carefully round with hobbies and little luxuries; avoid all entanglements; lock it up safe in the casket or coffin of your selfishness. But in that casket – safe, dark, motionless, airless – it will change. It will not be broken; it will become unbreakable, impenetrable, irredeemable. The alternative to tragedy, or at least to the risk of tragedy, is damnation. The only place outside Heaven where you can be perfectly safe from all the dangers and perturbations of love is Hell.”

“Here and there amidst the wreckage, she found advanced devices that more or less still functioned. With one exception, she’d revealed these to Johanna and then to Woodcarver, and—after it was founded—to the Executive Council. Ravna had kept her mouth shut about the surveillance suite; she and the Children were trapped on a world of medieval strangers....So at the beginning Ravna had kept some secrets. It was now years too late to reveal this one. In the Beyond, “cameras” were more than what early tech civilizations imagined. Cameras could be a coat of paint, or critters that looked like insects, or even a bacterial infection. Delivery of the information to the observer could be even stranger, a diffuse cloud of perturbations—acoustic, visual, thermal—that took enormous processing to reconstruct.”

“Trying to please everybody is what you'll soon get tired of, because as time goes on, those you're pleasing will get tired of you.”

“Be so free that nothing more than your future can distract your attention.”

“Confidence is what we get when we take fear, face it and replace it.”
