Quotes & Sayings About Differential

There is a mathematical underpinning that you must first acquire, mastery of each mathematical subdiscipline leading you to the threshold of the next. In turn you must learn arithmetic, Euclidian geometry, high school algebra, differential and integral calculus, ordinary and partial differential equations, vector calculus, certain special functions of mathematical physics, matrix algebra, and group theory. For most physics students, this might occupy them from, say, third grade to early graduate school - roughly 15 years. Such a course of study does not actually involve learning any quantum mechanics, but merely establishing the mathematical framework required to approach it deeply. — Carl Sagan

I'm really good with problems. I can solve a differential equation in my head. I chew through trig angles like candy. I know this, and it just makes it worse. Because I don't know how to solve this one. — Kekla Magoon

What you need to learn how to do is analyze situations and do differential diagnoses and understand the principle and the concepts rather than learn all the details, and medical school doesn't begin to do that. — Leroy Hood

There's no doubt that scientific training helps many authors to write better science fiction. And yet, several of the very best were English majors who could not parse a differential equation to save their lives. — David Brin

[Mathematics] is security. Certainty. Truth. Beauty. Insight. Structure. Architecture. I see mathematics, the part of human knowledge that I call mathematics, as one thing-one great, glorious thing. Whether it is differential topology, or functional analysis, or homological algebra, it is all one thing ... They are intimately interconnected, they are all facets of the same thing. That interconnection, that architecture, is secure truth and is beauty. That's what mathematics is to me. — Paul Halmos

Including the differential mortgage loan approval rates between Asian Americans and whites shows that the same methods to conclude that that blacks are discriminated against in mortgage lending would also lead to the conclusion that whites are discriminated against in favor of Asian Americans, reducing this whole procedure to absurdity, since no one believes that banks are discriminating against whites ... [W]hen loan approval rates are not cited, but loan denial rates are, that creates a larger statistical disparity, since most loans are approved. Even if 98 percent of blacks had their mortgage loan applications approved, if 99 percent of whites were approved than by quoting denial rates alone it could be said that blacks were rejected twice as often as whites. — Thomas Sowell

Well, coming back to public issues and small investors, it is worth mentioning one example from ICICI bank. Towards the end of 2005 ICICI bank conducted its FPO to raise close to Rs 5,000 crores. It was announced that retail investors would be allotted shares at a rate fiver percent below the cutoff price determined by book building process. Every other section of investors were allotted shares at Rs 525 each. The same shares were offered to retail investors at Rs 498.75. A company can propose to issue shares at different prices for different categories of investors. Such a facility is known as 'differential pricing'. That would happen only if the company feels it would be difficult to get rid of the supply to a particular section of investors. Otherwise, — Chellamuthu Kuppusamy

If God has made the world a perfect mechanism, He has at least conceded so much to our imperfect intellect that in order to predict little parts of it, we need not solve innumerable differential equations, but can use dice with fair success. — Max Born

I would suggest that especially in the differential of images that arise, in the inflections that we find within the representations of women we may also recover a subjectivity for women. For this reason also I am specifically interested in bringing to light other models for women's roles, models that upset business as usual and offer a greater diversity of possibilities for the easy we can imagine women. — Loriliai Biernacki

It is well known that the central problem of the whole of modern mathematics is the study of transcendental functions defined by differential equations. — Felix Klein

I thought of computers as very low class. I thought of myself as a pure mathematician and was interested in partial differential equations and topology and things like that. — Whitfield Diffie

At the Stourbridge Fair in 1663, at age twenty, he purchased a book on astrology, "out of a curiosity to see what there was in it." He read it until he came to an illustration which he could not understand, because he was ignorant of trigonometry. So he purchased a book on trigonometry but soon found himself unable to follow the geometrical arguments. So he found a copy of Euclid's Elements of Geometry, and began to read. Two years later he invented the differential calculus. — Carl Sagan

We have the only cookbook in the world that has partial differential equations in it. — Nathan Myhrvold

To those critics who see capitalism as a system of inegalitarian, oppressive structures, its defenders have vaunted its ability to recognize and encourage what they call individual merit and asserted not only the desirability but also the inevitability of differential reward, of earned privilege, so to speak. — Immanuel Wallerstein

For memetics to be a reasonable research programme, it should be the case that copying, and differential success in causing the multiplication of copies, overwhelmingly plays the major role in shaping all or at least most of the contents of culture. Evolved domain-specific psychological dispositions, if there are any, should be at most a relatively minor factor that could be considered part of background conditions. — Dan Sperber

The basic formulation, or bare-bones mechanics, of natural selection is a disarmingly simple argument, based on three undeniable facts (overproduction of offspring, variation, and heritability) and one syllogistic inference (natural selection, or the claim that organisms enjoying differential reproductive success will, on average, be those variants that are fortuitously better adapted to changing local environments, and that these variants will then pass their favored traits to offspring by inheritance). — Stephen Jay Gould

Rain is the last thing you want when you're chasing someone in Miami. They drive shitty enough as it is, but on top of that, snow is a foreign concept, which means they never got the crash course in traction judgment for when pavement slickness turns less than ideal. And because of the land-sea temperature differential, Florida has regular afternoon rain showers. Nothing big, over in a jiff. But minutes later, all major intersections in Miami-Dade are clogged with debris from spectacular smash-ups. In Northern states, snow teaches drivers real fast about the Newtonian physics of large moving objects. I haven't seen snow either, but I drink coffee, so the calculus of tire-grip ratio is intuitive to my body. — Tim Dorsey

But just as much as it is easy to find the differential [derivative] of a given quantity, so it is difficult to find the integral of a given differential. Moreover, sometimes we cannot say with certainty whether the integral of a given quantity can be found or not. — Johann Bernoulli

Knowing what is big and what is small is more important than being able to solve partial differential equations. — Stanislaw Ulam

Science is the Differential Calculus of the mind. Art the Integral Calculus; they may be beautiful when apart, but are greatest only when combined. — Ronald Ross

Well, not the stuff they use in robotics, which I wouldn't follow, but sociological relationships I can handle. For instance, I'm familiar with the Teramin Relationship." "The what, sir?" "Maybe you have a different name for it. The differential of inconveniences suffered with privileges granted: dee eye sub jay taken to the nth - - " "What are you talking about? — Isaac Asimov

What is the origin of the urge, the fascincation that drives physicists, mathematicians, and presumably other scientists as well? Psychoanalysis suggests that it is sexual curiosity. You start by asking where little babies come from, one thing leads to another, and you find yourself preparing nitroglycerine or solving differential equations. This explanation is somewhat irritating, and therefore probably basically correct. — David Ruelle

The chief difficulty of modern theoretical physics resides not in the fact that it expresses itself almost exclusively in mathematical symbols, but in the psychological difficulty of supposing that complete nonsense can be seriously promulgated and transmitted by persons who have sufficient intelligence of some kind to perform operations in differential and integral calculus ... — Celia Green

In matters outside the courtroom, courts have decried differential treatment between print and broadcast media. New York City mayoral candidates Mario Cuomo and Edward Koch tried to exclude selected members of the media in 1977 by limiting access to their campaign headquarters to those who had received invitations. Ruling in American Broadcasting Cos. v. Cuomo, a federal court observed, "once there is a public function, public comment, and participation by some of the media, the First Amendment requires equal access to all of the media or the rights of the First Amendment would no longer be tenable."44
In 1981, a federal court in Georgia struck down a judge's order excluding television crews from a White House press pool. The court said the order violated the press and public's First Amendment right of access to White House events. It felt television coverage "provides a comprehensive visual element and an immediacy, or simultaneous aspect, not found in print — Marjorie Cohn

I argue that even as the war is framed in certain ways to control and heighten affect in relation to the differential grievability of lives, so war has come to frame ways of thinking multiculturalism and debates on sexual freedom, issues largely considered separate from foreign affairs. — Judith Butler

The differential diagnosis of catatonia According to an old story, there are three different types of baseball umpires. The first says: "I call them lballs and strikes] as they are"; the second says: "I call them as I see them"; and the third says: "What I call them is what they become. — Max Fink

The aim of Mathematical Physics is not only to facilitate for the physicist the numerical calculation of certain constants or the integration of certain differential equations. It is besides, it is above all, to reveal to him the hidden harmony of things in making him see them in a new way. — Henri Poincare

A major triumph of mathematical imagination: the use of visual imagery to condense a large quantity of information into a single comprehensible picture ... Mathematicians are just beginning to understand these basic building blocks of change and to analyze how they combine. The methodology involved has a very different spirit from traditional modeling with differential equations: it is more like chemistry than calculus, requiring careful counterpoint between analysis and synthesis. — Ian Stewart

A study of interactions between women and obstetricians offers an explanation. It described three levels of increasing power imbalance: In the first, you fight and lose; in the second you don't fight because you know you can't win. However, in the highest level of power differential, your preferences are so manipulated that you act against your own interests, but you are content. Elective [meaning requested for no medical reason, not to be confused with needed surgery planned in advance] repeat cesarean exemplifies that highest level. — Henci Goer

The cross-section of a helicopter blade, according to Sarah, is more or less the same as the wing of an aeroplane. Its shape creates a pressure differential in the air passing over its upper and lower surfaces, producing a consequent lift. It differs from an aeroplane wing, however, in that when a helicopter moves forward, air starts passing over the blade that's coming forward faster than it passes over the blade that's going backwards. This produces unequal lift on the two sides of the helicopter, and the faster it goes, the more unequal the lift becomes. Eventually the 'retreating' blade stops producing any lift at all, and the helicopter flips on to its back and drops out of the sky. This, according to Sarah, was a negative aspect. — Hugh Laurie

We were all involved in the death of John Kennedy. We tolerated hate; we tolerated the sick stimulation of violence in all walks of life; and we tolerated the differential application of law, which said that a man's life was sacred only if we agreed with his views. This may explain the cascading grief that flooded the country in late November. We mourned a man who had become the pride of the nation, but we grieved as well for ourselves because we knew we were sick. — Martin Luther King Jr.

As Dalla Costa put it, women's unpaid
labor in the home has been the pillar upon which the exploitation of the waged workers, "wage slavery," has been built, and the secret of ies productivity (1972:31). Thus, the power differential between women and men in capitalist societry cannot be attributed to the irrelevance of housework for capitalist accumulation - an irrelevance belied by the strict rules that have governed women's lives - nor CO the survival of timeless cultural schemes. Rather, it should be interpreted as the effect of a social system of production that does not recognize the production and reproduction of the worker as a social-economic activity. and a source of capital accumulation, but mystifies it instead as a natural resource or a personal service, willie profiting from the wageless conclition of the labor involved. — Silvia Federici

How many black holes have we been up close and personal with?" Kosta countered. "All sorts of odd things happen near the event horizon, from huge tidal forces to variations in time. Personally, I'm voting on it having to do with gravity, either a polarization of the fields themselves or else something related to the time differential."
I didn't know physics had become a democracy," Hanan murmered. — Timothy Zahn

Until now the theory of infinite series in general has been very badly grounded. One applies all the operations to infinite series as if they were finite; but is that permissible? I think not. Where is it demonstrated that one obtains the differential of an infinite series by taking the differential of each term? Nothing is easier than to give instances where this is not so. — Niels Henrik Abel

Every one who understands the subject will agree that even the basis on which the scientific explanation of nature rests is intelligible only to those who have learned at least the elements of the differential and integral calculus, as well as analytical geometry. — Felix Klein

"Do you know," the Devil confided, "not even the best mathematicians on other planets - all far ahead of yours - have solved it? Why, there is a chap on Saturn - he looks something like a mushroom on stilts - who solves partial differential equations mentally; and even he's given up." — Arthur Porges

The illegitimate use of a state by economic interests for their own ends is based upon a preexisting illegitimate power of the state to enrich some persons at the expense of others. Eliminate that illegitimate power of giving differential economic benefits and you eliminate or drastically restrict the motive for wanting political influence. — Robert Nozick

Among all of the mathematical disciplines the theory of differential equations is the most important ... It furnishes the explanation of all those elementary manifestations of nature which involve time. — Sophus Lie

The differential element of non-Euclidean spaces is Euclidean. This fact, however, is analogous to the relations between a straight line and a curve, and cannot lead to an epistemological priority of Euclidean geometry, in contrast to the views of certain authors. — Hans Reichenbach

Only by taking infinitesimally small units for observation (the differential of history, that is, the individual tendencies of men) and attaining to the art of integrating them (that is, finding the sum of these infinitesimals) can we hope to arrive at the laws of history. — Leo Tolstoy

An essential pedagogic step here is to relegate the teaching of mathematical methods in economics to mathematics departments. Any mathematical training in economics, if it occurs at all, should come after students have at the very least completed course work in basic calculus, algebra and differential equations (the last being one about which most economists are woefully ignorant). This simultaneously explains why neoclassical economists obsess too much about proofs and why non-neoclassical economists, like those in the Circuit School, experience such difficulties in translating excellent verbal ideas about credit creation into coherent dynamic models of a monetary production economy. — Steve Keen

But the point is that a story is exciting because it has in it so strong an element of will, of what theology calls free-will. You cannot finish a sum how you like. But you can finish a story how you like. When somebody discovered the Differential Calculus there was only one Differential Calculus he could discover. But when Shakespeare killed Romeo he might have married him to Juliet's old nurse if he had felt inclined. And Christendom has excelled in the narrative romance exactly because it has insisted on the theological free-will. — G.K. Chesterton

But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes. — Antonin Artaud

In such a view, time is not emergent. It is, in fact, the only aspect of reality that cannot emerge from a more fundamental background. We register its reality, always and everywhere, by recognizing the differential character of change: some things change relative to other things. However, the kinds of things that there are also change, and so do the ways in which they change. That is what time is: the transformation of transformation. — Roberto Mangabeira Unger

Given the historical power differential between blacks and whites, blacks are required to be attentive to the way their white counterparts see themselves in relation to people of color if they want to survive and even thrive. — James A. Forbes

Around the turn of the century Amazon was caught up in a controversy about "differential pricing." Essentially this means that an online site might charge you more for given items than it charges other people, like your neighbors.2 Amazon stated at the time that it was not really discrimination, but experimentation. It was offering different prices to different people to see what they would pay. There is nothing special about Amazon in this regard. Another example is the travel site Orbitz, which was found to be directing users of more expensive computers to more expensive travel options.3 Who could be surprised? It is natural for a business to take — Jaron Lanier

The physical structure of the Internet presents a suggestive story about the concentration of power - it contains "backbones" and "hubs" - but power on the Internet is not spatial but informational; power inheres in protocol. The techno-libertarian utopianism associated with the Internet, in the gee-whiz articulations of the Wired crowd, is grounded in an assumption that the novelty of governance by computer protocols precludes control by corporation or state. But those entities merely needed to understand the residence of power in protocol and to craft political and technical strategies to exert it. In 2006, U.S. telecommunications providers sought to impose differential pricing on the provision of Internet services. The coalition of diverse political interests that formed in opposition - to preserve "Net Neutrality" - demonstrated a widespread awareness that control over the Net's architecture is control of its politics. — Samir Chopra

Baseball players or cricketers do not need to be able to solve explicitly the non-linear differential equations which govern the flight of the ball. They just catch it. — Paul Ormerod

Differential equations won't help you much in the design of aeroplanes - not yet, anyhow. — Nevil Shute

This is what income inequality means in America, and why the gap between the very rich and everyone else is growing wider. According to a recent study, CEO pay is now 295 times more than the pay of a typical worker. In 1965, the differential was 20 times. We must create an economy that works for all, not just the top 1%. — Bernie Sanders

Expected outcomes contribute to motivation independently of self-efficacy beliefs when outcomes are not completely controlled by quality of performance. This occurs when extraneous factors also affect outcomes, or outcomes are socially tied to a minimum level of performance so that some variations in quality of performance above and below the standard do not produce differential outcomes — Albert Bandura

Hydrodynamics procreated complex analysis, partial differential equations, Lie groups and algebra theory, cohomology theory and scientific computing. — Vladimir Arnold

Messages from the unseen that the great Alan Turing left behind at his death: Science is a differential equation. Religion is a boundary condition. — Jim Holt

You were outside?" I said.
"Making reindeer tracks."
I lifted my brows.
"Did you hear the kids earlier, talking about reindeer?"
Kate had been concerned that the chalet roof was too steep for the reindeer to touch down on, and Logan insisted they didn't really fly.
[ ... ]
"So you made reindeer tracks?" I said.
"I did. Not on the roof, of course. That wouldn't work. But they landed in the middle of the yard, then walked over to the house. I figured that should do the trick. I considered adding deer droppings, but Logan would figure out the size differential, so I settled for tracks. Plus a few tufts of deer hair caught in the bushes."
"And you gave our kids flying reindeer."
"I did."
I put my arms around his neck, and wrapped my hands in his damp hair and kissed him.
"God, I love you. — Kelley Armstrong

Man's destiny is to know, if only because societies with knowledge culturally dominate societies that lack it. Luddites and anti-intellectuals do not master the differential equations of thermodynamics or the biochemical cures of illness. They stay in thatched huts and die young. — E. O. Wilson

How did Biot arrive at the partial differential equation? [the heat conduction equation] ... Perhaps Laplace gave Biot the equation and left him to sink or swim for a few years in trying to derive it. That would have been merely an instance of the way great mathematicians since the very beginnings of mathematical research have effortlessly maintained their superiority over ordinary mortals. — Clifford A. Truesdell

The difficulty involved in the proper and adequate means of describing changes in continuous deformable bodies is the method of differential equations ... They express mathematically the physical concept of contiguous action.
Einstein's Theory of Relativity — Max Born

Leaders create an environment in which everyone has the opportunity to do work which matches his potential capability and for which an equitable differential reward is provided. — Elliott Jaques

Wherever I'm going, I'll be there to apply the formula. I'll keep the secret intact.
It's simple arithmetic.
It's a story problem.
If a new car built by my company leaves Chicago traveling west at 60 miles per hour, and the rear differential locks up, and the car crashes and burns with everyone trapped inside, does my company initiate a recall?
You take the population of vehicles in the field (A) and multiple it by the probable rate of failure (B), then multiply the result by the average cost of an out-of-court settlement (C).
A times B times C equals X. This is what it will cost if we don't initiate a recall.
If X is greater than the cost of a recall, we recall the cars and no one gets hurt.
If X is less than the cost of a recall, then we don't recall. — Chuck Palahniuk

Training in rapid acoustic discrimination can apparently induce the left prefrontal cortex, which is normally attuned to fast-changing acoustic stimuli but is disrupted in dyslexics, to do its job. The region, even in adults, remains "plastic enough...to develop such differential sensitivity after intensive training," the scientists concluded. — Jeffrey M. Schwartz

Basically, we try to buy value expressed in the differential between its price and what we think its worth. — Walter Schloss

Millions of statements are made about the president every day on every subject and from every standpoint; threats of violence are not an integral feature of any one subject or viewpoint as distinct from others. Differential treatment of threats against the president, then, selects nothing but special risks, not special messages. — David Souter

By June 1949 people had begun to realize that it was not so easy to get a program right as had at one time appeared. I well remember when this realization first came on me with full force. The EDSAC was on the top floor of the building and the tape-punching and editing equipment one floor below on a gallery that ran round the room in which the differential analyzer was installed. I was trying to get working my first non-trivial program, which was one for the numerical integration of Airy's differential equation. It was on one of my journeys between the EDSAC room and the punching equipment that "hesitating at the angles of stairs" the realization came over me with full force that a good part of the remainder of my life was going to be spent in finding errors in my own programs. — Martin Campbell-Kelly

I know this may sound like an excuse," he said. "But tensor functions in higher differential topology, as exemplified by application of the Gauss-Bonnett Theorem to Todd Polynomials, indicate that cohometric axial rotation in nonadiabatic thermal upwelling can, by random inference derived from translational equilibrium aggregates, array in obverse transitional order the thermodynamic characteristics of a transactional plasma undergoing negative entropy conversions."
"Why don't you just shut up," said Hardesty. — Mark Helprin

I do believe that everyone growing up faces differential opportunities. With me, it was books and travel and some good teachers. — James A. Michener

The asymmetry of power that cuteness revolves around is another compelling reminder of how aesthetic categories register social conflict. There can be no experience of any person or object as cute that does not somehow call up the subject's sense of power over those who are less powerful. But, as Lori Merish underscores, the fact that the cute object seems capable of making an affective demand on the subject - a demand for care that the subject is culturally as well as biologically compelled to fulfill - is already a sign that "cute" does not just denote a static power differential, but rather a dynamic and complex power struggle. — Sianne Ngai

The education of the senses has, as its aim, the refinement of the differential perception of stimuli by means of repeated exercises. — Maria Montessori

The education situation which most effectively promotes significant learning is one in which (1) threat to the self of the learner is reduced to a minimum and (2) differential perception of the field of experience is facilitated — Carl Rogers

(I)f you try to treat the medical problem you *think* you see without fully exploring the differential diagnosis -- call(ed) "speculation on a foundation of assumption" -- you can kill your patient. — Judy Melinek

Newton, of course, was the inventor of differential calculus so his place in the tale is quite special. — Kit Williams

The great paradox of the civil rights revolution is that instead of enforcing and expanding equality before the law, the revolution created differential rights based on race, gender and, any day now, sexual orientation. The great liberal revolution, centuries in the making, that brought forth equality in law has been overthrown. In its place we see rising a new feudal legal order of status-based rights. — Paul Craig Roberts

Once sufficient concentration and merging have taken place, the winners hope to be free to establish a more orderly form of competition between themselves, one where they create differential advantages for their stores, so that 'their shoppers' no longer see one store as substitutable for any other. — Greg Thain

We urgently need to find ways to push scientific and technological progress in directions that are likely to bring us good, and away from those directions that spell doom. This cannot be done if we stick to the erroneous view that all such progress is good for us. The first thing we need is to be able to distinguish those advances whose potential is most in the direction of prosperity and human flourishing from those whose potential is more in the direction of destruction and doom, and we need to find safe ways to handle those technologies that come with elements of both. Our ability to do so today is very limited, my ambition with this book is to draw attention to the problem, so that we can work together to improve, and avoid running blindfolded at full speed into a dangerous future. — Olle Haggstrom

Nothing has afforded me so convincing a proof of the unity of the Deity as these purely mental conceptions of numerical and mathematical science which have been by slow degrees vouchsafed to man, and are still granted in these latter times by the Differential Calculus, now superseded by the Higher Algebra, all of which must have existed in that sublimely omniscient Mind from eternity. — Mary Somerville

Natural selection based on the differential multiplication of variant types cannot exist before there is material capable of replicating itself and its own variations, that is, before the origination of specifically genetic material or gene-material. — Hermann Joseph Muller

Only by assuming an infinitesimally small unit for observation - a differential of history (that is, the common tendencies of men) - and arriving at the art of integration (finding the sum of the infinitesimals) can we hope to discover the laws of history. — Leo Tolstoy

The arts and humanities are not mere entertainment, to be turned to for relaxation after a busy day spent solving differential equations; they are our templates for living, for governing ourselves and our societies. Nor can science offer any help with the knottier problems besetting the human race. It can remedy bad smells, bad pains, and bad roads, but not bad behavior, bad government, or bad ideas. — John Derbyshire

In order to solve this differential equation you look at it till a solution occurs to you. — George Polya

Tom and I didn't have a problem with the height differential but Paramount did, so we tried to hide it. — Kelly McGillis

While researching this answer, I managed to lock up my copy of Mathematica several times on balloon-related differential equations, and subsequently got my IP address banned from Wolfram|Alpha for making too many requests. The ban-appeal form asked me to explain what task I was performing that necessitated so many queries. I wrote, "Calculating how many rental helium tanks you'd have to carry with you in order to inflate a balloon large enough to act as a parachute and slow your fall from a jet aircraft." Sorry, Wolfram. — Randall Munroe

The development of methods to monitor protein dynamics in cells together with the discovery of specific and general lysosomal inhibitors have resulted in the identification of different classes of cellular proteins, long- and short-lived, and the findings of the differential effects of the inhibitors on these groups. — Aaron Ciechanover

As I was working I noticed that the way I designed the differential gearing actually created a spare drive that sat directly below the emperor's feet, or where they would be if he were to sit in the chariot. — Kit Williams

Now, I like to think that I'm of reasonable intelligence, but ordinary differential equations and myself...we don't really hang in the same comprehension circles. So, try as I might to follow my teacher's logic in how he got 3f"(x) + 5xf(x) to equal eleven, I never quite understood. His answer in no way, shape, or form resembled mine, and this misalignment -this complete confusion of how point A got to point B- is kind of where I'm at right now. "Dreaming?" I repeat dubiously. — E.J. Mellow

Objectivity means being accountablefor marks on bodies, that is, specific materializations in their differential mattering. We are responsible for the cuts that we help enact not because we do the choosing (neither do we escape responsibility because "we" are "chosen" by them), but because we are an agential part of the material becoming of the universe. — Karen Barad

Can people of color be racist?" I reply, "The answer depends on your definition of racism." If one defines racism as racial prejudice, the answer is yes. People of color can and do have racial prejudices. However, if one defines racism as a system of advantage based on race, the answer is no. People of color are not racist because they do not systematically benefit from racism. And equally important, there is no systematic cultural and institutional support or sanction for the racial bigotry of people of color. In my view, reserving the term racist only for behaviors committed by whites in the context of a white-dominated society is a way of acknowledging the ever-present power differential afforded whites by the culture and institutions that make up the system of advantage and continue to reinforce notions of white superiority. (Using the same logic, I reserve the word sexist for men. Though women can and do have gender-based prejudices, only men systematically benefit from sexism.) — Paula S. Rothenberg

The ultimate goal of a meteorologist is to set up differential equations of the movements of the air and to obtain, as their integral, the general atmospheric circulation, and as particular integrals the cyclones, anticyclones, tornados, and thunderstorms. — Andrija Maurovic

2:40AM - 2:41AM (erotic_performance.exe): The curtain opened to reveal a Gateway 2000 computer and monitor running a Fenestra 98 operating system. The display booted up and opened a program on its desktop. The computer then began to rapidly recite a multitude of differential equations as well as their respective 3D graphical representations for 20 seconds. At the end of the program, the monitor displayed the word "INSERT" in the form of a screensaver. D-6744 and D-3432 both inserted $5 into its floppy drive. The curtain then closed at the end of the show. — Anonymous

As Darwin himself was at pains to point out, natural selection is all about differential survival within species, not between them. — Richard Dawkins

Anyone with special abilities earns a differential return on that flair, which we economists call a rent. Those few with extraordinary P.Q. (Performance Quotient) will not give away such rent to the Ford Foundation or the local bank trust department. They have too high an I.Q. for that. — Paul Samuelson

All life evolves by the differential survival of replicating entities — Richard Dawkins

Consider paint a film of light reflecting/absorbing material, and a colored paint a material which gives a particular, characteristic transmission of light via differential absorption and reflection. Call this reflected quality 'luminance' and measure it in millilamberts. This measure is as real and present as height, breadth, depth; and I find the phenomenon equally sumptuous and convincing ... Painted light, not color, not form, not perspective, or line, not image, or words, or equations, is painting. I make paintings which do not represent light, they are light. — Jo Baer

I was brought up in southwestern Ontario where we were taught that Canadian patriotism should not withstand anything more than a five-dollar-a-month wage differential. Anything more than that and you went to Detroit. — John Kenneth Galbraith

I'm very good at integral and differential calculus, I know the scientific names of beings animalculous; In short, in matters vegetable, animal, and mineral, I am the very model of a modern Major-General. — W.S. Gilbert

Therefore, I have attacted [the problem of the catenary] which I had hitherto not attempted, and with my key [the differential calculus] happily opened its secret.
Acta eruditorum — Gottfried Leibniz

Profits are not made by differential cleverness, but by differential stupidity. — David Ricardo

It is a curious historical fact that modern quantum mechanics began with two quite different mathematical formulations: the differential equation of Schroedinger and the matrix algebra of Heisenberg. The two apparently dissimilar approaches were proved to be mathematically equivalent. — Richard P. Feynman

Stalin was the most audible and powerful spokesman in the campaign against what he contemptuously called uravnilovka (leveling). His hostility - voiced in sarcastic and dismissive terms - was so deep and so clearly enunciated that it rapidly became state policy and social doctrine. He believed in productive results, not through spontaneity or persuasion, but through force, hierarchy, reward, punishment, and above all differential wages. He applied this view to the whole of society. Stalin's anti-egalitarianism was not born of the five-year plan era. He was offended by the very notion and used contemptuous terms such as "fashionable leftists", "blockheads", "petty bourgeois nonsense" and "silly chatter," thus reducing the discussion to a sweeping dismissal of childish, unrealistic, and unserious promoters of equality. The toughness of the delivery evoked laughter of approval from his audience. — Richard Stites

Natural selection is all about the differential success of rival DNA in getting itself transmitted vertically in the species archives. — Richard Dawkins

There was a three hour differential in performances because the sponsor insisted it be done live for California. You would go on at 8 pm in New York but you would also have to go on at 8 p.m. in California. That meant coming back in to do the show at 11 p.m. — Dick York

Democracy turns upon and devours itself. Universal suffrage, in theory the palladium of our liberties, becomes the assurance of our slavery. And that slavery will grow more and more abject and ignoble as the differential birth rate, the deliberate encouragement of mendicancy and the failure of popular education produce a larger and larger mass of prehensile half-wits, and so make the demagogues more and more secure. — H.L. Mencken
