Perturbation Quotes & Sayings

Bifurcation occurs when the environment of a potentially chaotic system destabilizes due to stress over time, or to some inciting disturbance, explosive or catastrophic.

Elizabeth's mind was too full for conversation, but she saw and admired every remarkable spot and point of view. — Jane Austen

The vice named surrealism is the immoderate and impassioned use of the stupefacient image or rather of the uncontrolled provocation of the image for its own sake and for the element of unpredictable perturbation and of metamorphosis which it introduces into the domain of representation; for each image on each occasion forces you to revise the entire Universe. — Louis Aragon

He entered a confectioner's shop to rest, once. He was in a state of nervous excitement and perturbation; he noticed nothing and no one; and he felt a craving for solitude, to be alone with his thoughts and his emotions, and to give himself up to them passively.

It" is the idea of him or her that resides in us--inspired by the "Something" in them, as Pope has it, "That gives us back the Image of our Mind." Although the perception of It must be excited by some extraordinary perturbation in the looks and personality of the adored, the aura that It broadcasts arises not merely from the singularity of an original, as Walter Benjamin supposed, but also from the fabulous success of its reproducibility in the imaginations of many others, charmed exponentially by the number of its copies. The one-of-kind item must become a type, a replicable role-icon of itself--from "a Charles Hart" or "a Nell Gwyn" to "a Mary Pickford" or "a Douglas Fairbanks"--in order to unleash the Pygmalion effect in the hearts and minds of the fans, making the idea of him or her theirs--as much or more than anything else they might call their own. — Joseph Roach

In spite of his exceeding mental perturbation, Simpson struggled hard to detect its nature, and define it, but the ascertaining of an elusive scent, not recognized subconsciously and at once, is a very subtle operation of the mind. And he failed. It was gone before he could properly seize or name it. Approximate description, even, seems to have been difficult, for it was unlike any smell he knew. Acrid rather, not unlike the odor of a lion, he thinks, yet softer and not wholly unpleasing, with something almost sweet in it that reminded him of the scent of decaying garden leaves, earth, and the myriad, nameless perfumes that make up the odor of a big forest. Yet the 'odor of lions' is the phrase with which he usually sums it all up.
("The Wendigo") — Algernon Blackwood

A great perturbation in nature, to receive at once the benefit of sleep and do the effects of watching! — William Shakespeare

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] — Paul Davies

A feeble mind, conscious of its own feebleness, grows feeble under that very consciousness. As soon as the power of fear becomes known to it, there follows the fear of fear, and, on the first perturbation, reason abandons it. — Hector Berlioz

The wind then became calmed in some degree: when, after sun-rise, we perceived that the mountain we had seen was in the air, and that we could see light between it and the sea. I was much astonished at this: but, seeing the sailors in the utmost perturbation, and bidding farewell to one another, I said, Pray what is the matter? They said, What we supposed to be a mountain, is really a Rokh,1 and if he sees us, we shall assuredly perish, there being now between us and him a distance of ten miles only. But God, in his goodness, gave us a good wind, and we steered our course in a direction from him, so that we saw no more of him; nor had we any knowledge of the particulars of his shape. — Ibn Battuta

The danger of delusion was made worse, by the love of delusion. What's best for me and what is worst for me, the thing I most ought to do and the thing I most ought not to do, look very much alike. In my heart of hearts I may know which is which - but then a spirit of perversity makes me want to choose wrongly. Great psychic perturbation always surrounds great beauty — Mark Booth

In that moment, as they stood smiling at one another, Charlotte was conscious of several contradictory sensations, of which the chief were these: annoyance with herself for being incapable of governing her own actions, satisfaction that Sidney had won this very minor victory over her, amusement, embarrassment - an odd something between perturbation and pleasure - and above all else, a flutter of joyful spirits which made her feel she had strayed somehow into a most unfamiliar world. — Jane Austen
