“A thrown-stone trajectory is a good metaphor for so many phenomena: the curve of an event, any event; the curve of a life, any life; the curve of a hypothesis; the curve experienced in the manufacture of a work of art; the curve of interest experienced in the manufacture of a catalogue.”

“Yes it was 1949. How I came to that. That's like how one gets to know a human being. It so happens that I've always had a preference – as everyone has prejudices and preferences – for the square as a shape in preference to the circle as a shape. And I have known for a long time that a circle always fools me by not telling me whether it's standing still or not. And if a circle circulates you don't see it. The outer curve looks the same whether it moves or does not move. So the square is much more honest and tells me that it is sitting on one line of the four, usually a horizontal one, as a basis. And I have also come to the conclusion that the square is a human invention, which makes it sympathetic to me. Because you don't see it in nature. As we do not see squares in nature, I thought that it is man-made. But I have corrected myself. Because squares exist in salt crystals, our daily salt. We know this because we can see it in the microscope. On the other hand, we believe we see circles in nature. But rarely precise ones. Mature, it seems, is not a mathematician. Probably there are no straight lines either. Particularly not since Einstein says in his theory of relativity that there is no straight line, rod knows whether there are or not, I don't. I still like to believe that the square is a human invention. And that tickles me. So when I have a preference for it then I can only say excuse me.”

“I could give here several other ways of tracing and conceiving a series of curved lines, each curve more complex than any preceding one, but I think the best way to group together all such curves and them classify them in order, is by recognizing the fact that all points of those curves which we may call "geometric," that is, those which admit of precise and exact measurement, must bear a definite relation to all points of a straight line, and that this relation must be expressed by a single equation. If this equation contains no term of higher degree than the rectangle of two unknown quantities, or the square of one, the curve belongs to the first and simplest class, which contains only the circle, the parabola, the hyperbola, and the ellipse; but when the equation contains one or more terms of the third or fourth degree in one or both of the two unknown quantities (for it requires two unknown quantities to express the relation between two points) the curve belongs to the second class; and if the equation contains a term of the fifth or sixth degree in either or both of the unknown quantities the curve belongs to the third class, and so on indefinitely.”

“Finally anger took possession of him. It was his turn to ask the question already raised by so many others: We, down there, the ones who join up, we're giving everything we have to give, maybe our arms and our two legs. He looked up at the high grills, the curving driveways, the sumptuous facades, and completed his thought: Are these people giving all they have to give?”

“While then for a long time everyone was at a loss, Hippocrates of Chios was the first to observe that, if between two straight lines of which the greater is double of the less it were discovered how to find two mean proportionals in continued proportion, the cube would be doubled; and thus he turned the difficulty in the original problem into another difficulty no less than the former. Afterwards, they say, some Delians attempting, in accordance with an oracle, to double one of the altars fell into the same difficulty. And they sent and begged the geometers who were with Plato in the Academy to find for them the required solution. And while they set themselves energetically to work and sought to find two means between two given straight lines, Archytas of Tarentum is said to have discovered them by means of half-cylinders, and Eudoxus by means of the so-called curved lines. It is, however, characteristic of them all that they indeed gave demonstrations, but were unable to make the actual construction or to reach the point of practical application, except to a small extent Menaechmus and that with difficulty.”

“There was no way, without full understanding, that one could have confidence that conditions the next time might not produce erosion three times more severe than the time before. Nevertheless, officials fooled themselves into thinking they had such understanding and confidence, in spite of the peculiar variations from case to case. A mathematical model was made to calculate erosion. This was a model based not on physical understanding but on empirical curve fitting.”

“In Professor Pigou's study the argument that free enterprise lead to excessive investments in industry having relatively upward-sloping cost curves is developed with the aid of concrete example, the case of two roads; Suppose that between two points there are two highways, one of which is broad enough to accommodate without crowding all the traffic which may care to use it, but is poorly graded and surfaced; while the other is a much better road, but narrow and quite limited in capacity. If a large number of trucks operate between the two termini and are free to choose either of the two routes, they will tend to distribute themselves between the roads in such proportions that the cost per unit of transportation, or effective returns per unit of investment, will be the same for every truck on both routes. As more trucks use the narrower and better road, congestion develops, until at a certain point it becomes equally profitable to use the broader but poorer highway.”

“The first notion of constructing a free goal-seeking mechanism goes back a wartime talk with the psychologist, Kenneth Craik, whose untimely death was one of the greatest losses Cambridge has suffered in years. When he was engaged on a warjob for the Government, he came to get the help of an automatic analyzer with some very complicated curves he had obtained, curves relating to the aiming errors of air gunners. Goal-seeking missiles were literally much in the air in those days; so, in our minds, were scanning mechanisms. Long before the home study was turned into a workshop, the two ideas, goal-seeking and scanning, had combined as the essential mechanical conception of a working model that would behave like a very simple animal.”

“Whenever like mates with like (genetically), the statistical distribution curve, which describes the frequency of the purely fortuitous combinations of genes, is flattened out, its mode is depressed, and its extremes are increased. The reduces the number of the mediocre produced and increases the numbers both of the sub-normal and the talented groups. It is possible that, without this increase in the number of extreme variants, no nation, race or group could produce enough superior individuals to maintain a complex culture. Certainly not enough to operate or advance a civilization. …Any number of social customs have stood, and still stand, in the way of an optimum amount of selective matings. In a feudal society, opportunities are denied to many able men who, consequently, never develop to the high level of their biological potential and thus they remain among the undistinguished. Such able men (and women) might also be diffused throughout an "ideal" classless society and, lacking the means to separate themselves from the generality, or to develop their peculiar talents, would be effectively swamped. In such a society they could hardly segregate in groups. In fact, only a few of the able males might ever meet an able female who appealed to them erotically. Obviously an open society—one in which the able may rise and the dim-wits sick, and where like intelligences have a greater chance of meeting and mating—has advantages that other societies do not have. Our own society today—incidentally and without design—is providing more and more opportunities for intelligent matrimonial discrimination. It is possible that our co-educational colleges, where highly-selected males and females meet when young, are as important in their function of bringing together the parents of our future superior individuals as they are in educating the present crop.”

“Alfie was an organizer. He would telephone the other kids a week before that first practice session (which he euphemistically called spring training), and he would knock on their doors the morning of, and they would look out the windows and say, "Hey, it's snowing," and he would say, "It's not snowing all that hard. See you in a half-hour." So we would gather our tired, cold bodies together, throw on our baseball clothes—old shirts, old pants, sneakers, old baseball gloves—and grab a couple of bats and scuffed-up balls, and we would pile onto the subway and ride to Van Cortland Park. We would run to make sure we'd be first to claim a ball field. Of course we were first. Nobody else was that crazy. My brother would direct practice for a couple of hours, batting practice, catching fungoes, fielding, practicing our curves and drops on the sidelines, fingers aching from contact with batted or thrown baseballs. We threw ourselves across that hard bone of a field so we would be ready when the spring suns finally thawed the ground at our feet. If the still-awake dreams of hunting lions in Africa were the peak moments of my night life, those frozen ball fields of February were the highlights of my days.”

“Of the contemporaries of Newton one of the most prominent was John Wallis. …Wallis was a voluminous writer, and not only are his writings erudite, but they show a genius in mathematics… He was one of the first to recognize the significance of the generalization of exponents to include negative and fractional as well as positive and integral numbers. He recognized also the importance of Cavalieri's method of indivisibles, and employed it in the quadrature of such curves as y=xn, y=x1/n, and y=x0 + x1 + x2 +… He failed in his attempts at the approximate quadrature of the circle by means of series because he was not in possession of the general form of the binomial theorem. He reached the result, however, by another method. He also obtained the equivalent of ds = \! dx \sqrt{1+(\frac{dy}{dx})^2} for the length of an element of a curve, thus connecting the problem of rectification with that of quadrature.”

“I remained there [in The Netherlands, 1914-18] for the duration of the war, continuing my work of abstraction in a series of church. facades, trees, houses, etc. But I felt that I still worked as an Impressionist and was continuing to express particular feelings, not pure reality. Although I was thoroughly conscious that we can never be absolutely 'objective', I felt that one can become less and less subjective, until the subjective no longer predominates in one's work. More and more I excluded from my painting all curved lines, until finally my compositions consisted only of vertical and horizontal lines which formed crosses, each separate and detached from the other. Observing sea, sky and stars, I sought to indicate their plastic function through a multiplicity crossing verticals and horizontals.”

“So I had carved one face with hollows curving in-out, in-out, very simple really. I set the timber upright and Frank Stella came in and came over and looked at the chiseling and said it looked good. He turned around to the back of the piece which was uncut – the backside of the timber – and he said, you know that's sculpture too. I supposed what he meant to say was, that cutting was a good idea and the idea of not cutting was good too. But you know, I thought to myself, yes the uncut side is really much better than the cut side. The form of the timber was by no way improved by my cutting into it. From that time, I began to think that the next timbers I get I'm not going to cut. I'm going to combine the timbers; I'm going to use them as cuts in space. I began to look for what I call 'particles”

“The range of H 1255 is only four tenths of a magnitude, and on account of its brightness it is difficult to observe on all plates except those taken with the 1-inch Cooke lens. It seemed necessary, therefore, to take unusual precautions in order to secure accurate observations, and to give each one its full weight. Accordingly, one hundred and thirty six photographs were selected, including nearly all of those taken with the Cooke lens, and also those taken with the 8 inch Bache Telescope on which the variable was certainly faint. Four independent estimates of brightness were made on each plate, and means were taken, thus reducing the probable error one half. The phase was computed for each observation, thus covering all parts of the light curve. …H 1255 and H 1303 differ from the other variables in a marked degree as in each case the duration of the phase of minimum is very long in proportion to the length of the period. This fact led to considerable difficulty in determining their periods as they were apparently at their minimum brightness for some time before and after the actual minima occurred. In H 1255, the change in brightness is obviously continuous throughout the period, although it is much more rapid near minimum than near maximum. This is clearly seen in Plate IV, Figs. 5 and 6.”

“The great Cartesian invention had its roots in those famous problems of antiquity which originated in the days of Plato. In endeavoring to solve the problems of the trisection of an angle, of the duplication of the cube and of the squaring of the circle, the ruler and compass having failed them, the Greek geometers sought new curves. They stumbled on the conic sections…There we find the nucleus of the method which Descartes later erected into a principle. Thus Apollonius referred the parabola to its axis and principal tangent, and showed that the semichord was the mean propotional between the latus rectum and the height of the segment. Today we express this relation by x2 = Ly, calling the height the ordinate (y) and the semichord the abscissa (x); the latus rectum being… L. …the Greeks named these curves and many others… loci… Thus the ellipse was the locus of a point the sum of the distances of which from two fixed points was constant. Such a description was a rhetorical equation of the curve…”

“Behold, the atheists' nightmare. Now if you study a well-made banana, you'll find, on the far side, there are three ridges. On the close side, two ridges. If you get your hand ready to grip a banana, you'll find on the far side there are three grooves, on the close side, two grooves. The banana and the hand are perfectly made, one for the other. You'll find the maker of the banana, Almighty God, has made it with a non-slip surface. It has outward indicators of inward contents — green: too early; yellow: just right; black: too late. Now if you go to the top of the banana, you'll find, as with the soda can makers have placed a tab at the top, so God has placed a tab at the top. When you pull the tab, the contents don't squirt in your face. You'll find a wrapper which is biodegradable, has perforations. Notice how gracefully it sits over the human hand. Notice it has a point at the top for ease of entry. It's just the right shape for the human mouth. It's chewy, easy to digest and its even curved toward the face to make the whole process so much easier. Seriously, Kirk, the whole of creation testifies to the genius of God's creation.”

“The melodic curves of speech are an expression of the complete organism and of all phases of its spiritual activities. They demonstrate whether a man is stupid or intelligent, sleepy or awake, tired or alert. They tell us whether he is a child or an old man, whether it is morning or evening, light or darkness, heat or frost, and disclose whether a person is alone or in company.

Thinking

“Suppose then I want to give myself a little training in the art of reasoning; suppose I want to get out of the region of conjecture and probability, free myself from the difficult task of weighing evidence, and putting instances together to arrive at general propositions, and simply desire to know how to deal with my general propositions when I get them, and how to deduce right inferences from them; it is clear that I shall obtain this sort of discipline best in those departments of thought in which the first principles are unquestionably true. For in all 59 our thinking, if we come to erroneous conclusions, we come to them either by accepting false premises to start with—in which case our reasoning, however good, will not save us from error; or by reasoning badly, in which case the data we start from may be perfectly sound, and yet our conclusions may be false. But in the mathematical or pure sciences,—geometry, arithmetic, algebra, trigonometry, the calculus of variations or of curves,—we know at least that there is not, and cannot be, error in our first principles, and we may therefore fasten our whole attention upon the processes. As mere exercises in logic, therefore, these sciences, based as they all are on primary truths relating to space and number, have always been supposed to furnish the most exact discipline. When Plato wrote over the portal of his school. “Let no one ignorant of geometry enter here,” he did not mean that questions relating to lines and surfaces would be discussed by his disciples. On the contrary, the topics to which he directed their attention were some of the deepest problems,—social, political, moral,—on which the mind could exercise itself. Plato and his followers tried to think out together conclusions respecting the being, the duty, and the destiny of man, and the relation in which he stood to the gods and to the unseen world. What had geometry to do with these things? Simply this: That a man whose mind has not undergone a rigorous training in systematic thinking, and in the art of drawing legitimate inferences from premises, was unfitted to enter on the discussion of these high topics; and that the sort of logical discipline which he needed was most likely to be obtained from geometry—the only mathematical science which in Plato’s time had been formulated and reduced to a system. And we in this country [England] have long acted on the same principle. Our future lawyers, clergy, and statesmen are expected at the University to learn a good deal about curves, and angles, and numbers and proportions; not because these subjects have the smallest relation to the needs of their lives, but because in the very act of learning them they are likely to acquire that habit of steadfast and accurate thinking, which is indispensable to success in all the pursuits of life.”

“In the third period, which lasted from the middle of the eighteenth century until late in the nineteenth century, attention was turned to critical investigations of the true nature of the number π itself, considered independently of mere analytical representations. The number was first studied in respect of its rationality or irrationality, and it was shown to be really irrational. When the discovery was made of the fundamental distinction between algebraic and transcendental numbers, i. e. between those numbers which can be, and those numbers which cannot be, roots of an algebraical equation with rational coefficients, the question arose to which of these categories the number π belongs. It was finally established by a method which involved the use of some of the most modern of analytical investigation that the number π was transcendental. When this result was combined with the results of a critical investigation of the possibilities of a Euclidean determination, the inferences could be made that the number π, being transcendental, does not admit of a construction either by a Euclidean determination, or even by a determination in which the use of other algebraic curves besides the straight line and the circle are permitted. The answer to the original question thus obtained is of a conclusive negative character; but it is one in which a clear account is given of the fundamental reasons upon which that negative answer rests.”

For it is a leap, it is a break in the smooth evolutionary curve, and a break is a wound, a pain. But the wound is necessary: most of mankind suffers from hereditary sleeping sickness, and victims of this sickness (entropy) must not be allowed to sleep, or it will be their final sleep, death.
The same disease often afflicts artists and writers: they sink into satiated slumber in forms once invented and twice perfected. And they lack the strength to wound themselves, to cease loving what they once loved, to leave their old, familiar apartments filled with the scent of laurel leaves and walk away into the open field, to start anew.
Of course, to wound oneself is difficult, even dangerous. But for those who are alive, living today as yesterday and yesterday as today is still more difficult.

“Our course of advance … is neither a straight line nor a curve. It is a series of dots and dashes.”

Benjamin N. Cardozo (1870–1938) United States federal judge

Other writings, The Paradoxes of Legal Science (1928)
Context: Our course of advance... is neither a straight line nor a curve. It is a series of dots and dashes. Progress comes per saltum, by successive compromises between extremes, compromises often … between "positivism and idealism". The notion that a jurist can dispense with any consideration as to what the law ought to be arises from the fiction that the law is a complete and closed system, and that judges and jurists are mere automata to record its will or phonographs to pronounce its provisions.

“The abstractions of Einstein's curved space and time gave rise to analogies and pictures that played a new explanatory role.”

John D. Barrow (1952–2020) British scientist

Cosmic Imagery: Key Images in the History of Science (2008)
Context: The abstractions of Einstein's curved space and time gave rise to analogies and pictures that played a new explanatory role. Space and time gave way to space-time, visible light was augmented by images across the rest of the electromagnetic spectrum, and we realised that we could see back towards the apparent beginnings of time.<!--part. 1, p. 8

“Mirror symmetry is concerned with counting the number of holomorphic curves on Calabi-Yau manifolds, i.e. compact Kähler manifolds X with trivial canonical bundle KX.”

“You must either make a tool of the creature, or a man of him. You cannot make both. Men were not intended to work with the accuracy of tools, to be precise and perfect in all their actions. If you will have that precision out of them, and make their fingers measure degrees like cog-wheels, and their arms strike curves like compasses, you must unhumanize them. All the energy of their spirits must be given to make cogs and compasses of themselves….On the other hand, if you will make a man of the working creature, you cannot make him a tool. Let him but begin to imagine, to think, to try to do anything worth doing; and the engine-turned precision is lost at once. Out come all his roughness, all his dulness, all his incapability; shame upon shame, failure upon failure, pause after pause: but out comes the whole majesty of him also; and we know the height of it only when we see the clouds settling upon him.”

“It was a long way down. Before she had gone very far the curious dizziness she had known before came over her again, a dizziness not entirely induced by the spirals she whirled around, but a deeper, atomic unsteadiness as if not only she but also the substances around her were shifting. There was something queer about the angles of those curves. She was no scholar in geometry or aught else, but she felt intuitively that the bend and slant of the way she went were somehow outside any other angles or bends she had ever known. They led into the unknown and the dark, but it seemed to her obscurely that they led into deeper darkness and mystery than the merely physical, as if, though she could not put it clearly even into thoughts, the peculiar and exact lines of the tunnel had been carefully angled to lead through poly-dimensional space as well as through the underground—perhaps through time, too.”

And that kind of blew me away (while shooting) a close-up. That was all new storytelling for me, and I had to figure it out on a very fast learning curve.”

“Since we all breathe, all the time, it is amazing what happens when someone else directs you how and when to breathe. And how vividly someone with no imagination whatsoever can see what he’s told is right there, complete with banister and rubber runners, curving down and rightward into a darkness that recedes before you.”

“Let the letters a b c denote the three angular points of a rectilineal triangle. If the point did move continuously over the lines ab, bc, ca, that is, over the perimeter of the figure, it would be necessary for it to move at the point b in the direction ab, and also at the same point b in the direction bc. These motions being diverse, they cannot be simultaneous. There-fore, the moment of presence of the movable point at vertex b, considered as moving in the direction ab, is different from the moment of presence of the movable point at the same vertex b, considered as moving in the same direction bc. But between two moments there is time; therefore, the movable point is present at point b for some time, that is, it rests. Therefore it does not move continuously, which is contrary to the assumption. The same demonstration is valid for motion over any right lines including an assignable angle. Hence a body does not change its direction in continuous motion except by following a line no part of which is straight, that is, a curve, as Leibnitz maintained.”

“These people are buying Brazil in installments. This purchase in the past was also done by demarcating land. Brazil would only make deals overseas in exchange for forgoing its sovereignty, demarcating indigenous territories, expanding parks. It can’t go on like this. You can’t do anything in 61 percent of Brazil. In some places, if you want to produce, you can’t, because you can’t go on a straight line to export, or sell, you have to go on a huge curve to go around a quilombola community, an indigenous territory, an environmental reserve. They’re ruining the country. As long as I am president, no indigenous land will be demarcated. They own 14 percent of the national territory. Imagine the Southeast—an area larger than that is indigenous. Isn’t that enough? Yesterday, I was once again with a group of indigenous people, and they want freedom to work in their area; they don’t want to live in confinement, like prehistoric beings.”

“Besides these improvements,… there are others,… which may… be interesting to those… engaged in those departments… Among these may be ranked, in the division of mechanics, properly so called, a simple demonstration of the law of the force by which a body revolves in an ellipsis; another of the properties of cycloidal pendulums; an examination of the mechanism of animal motions; a comparison of the measures and weights of different countries; and a convenient estimate of the effect of human labour: with respect to architecture, a simple method of drawing the outline of a column: an investigation of the best forms for arches; a determination of the curve which affords the greatest space for turning; considerations on the structure of the joints employed in carpentry, and on the firmness of wedges; and an easy mode of forming a kirb roof: for the purposes of machinery of different kinds, an arrangement of bars for obtaining rectilinear motion; an inquiry into the most eligible proportions of wheels and pinions; remarks on the friction of wheel work, and of balances; a mode of finding the form of a tooth for impelling a pallet without friction; a chronometer for measuring minute portions of time; a clock escapement; a calculation of the effect of temperature on steel springs; an easy determination of the best line of draught for a carriage; an investigation of the resistance to be overcome by a wheel or roller; and an estimation of the ultimate pressure produced by a blow.”

“The exact description of any physical process must include the effects of quantum gravity. But our experience suggests that there is a separation of scales, so that under suitable conditions we get 'lab physics'; i.e., physics described to good accuracy by quantum fields on gently curved spacetime.”
