Abstraction automatically gives rise to optimized solutions within the universal set of all possible solutions, as has been shown in this book. It is these optimized solutions that make up and drive the non-abstract parts of the world, while the non-optimized solutions remain ‘hidden’ from the material world, inside the abstract world. Starting from a basis of no postulation, we build our theory. As we go on piling up possibilities, we come to a similar basis for understanding the four non-contact forces of nature known till date. The difference in ranges of these forces is explained from this basis in this book. Zero postulation or abstraction as the basis of theory synthesis allows us to explore even imaginary and chaotic non-favoured solutions as possibilities. With no postulation as the fundamental basis, we are thus able to pile up postulated results or favoured results, but not the other way round. We keep describing such implications of abstraction in this book. We deal with the abstraction of observable parameters involved in a given system

Academics place much more importance on rigorous logic. There is also admiration in the profession for subtle reasoning. And mastery of the craft shows itself in the elegance of the intellectual super-structure…. The practitioner, on the other hand, uses economic theory only to the extent that he finds it useful in comprehending the problem at hand, so that practical courses of action will emerge which can be evaluated not merely in narrow economic cost-benefit terms, but by taking into account a wider range of considerations…. A practitioner is not judged by the rigour of his logic or by the elegance of his presentation. He is judged by results.

Admit only your victories until you have hooked their interest, then you draw them closer and admit the sort of failings that reflect well on a fellow, sentimental failings: that was the theory of courtship the young master had formulated...

… Fourier's great mathematical poem ... {Referring to Joseph Fourier's mathematical theory of the conduction of heat, one of the precursors to thermodynamics.}

His Theory of the Universe seems to have been, that it consisted solely of a multitude of objects which could be weighed, numbered, and measured; and the vocation to which he considered himself called was, to weigh, number and measure as many of those objects as his allotted three-score years and ten would permit. This conviction biased all his doings, alike his great scientific enterprises, and the petty details of his daily life.

Alas, the historical name is ‘actor-network-theory’, a name that is so awkward, so confusing, so meaningless that it deserves to be kept.

All scientific theories, even those in the physical sciences, are developed in a particular cultural context. Although the context may help to explain the persistence of a theory in the face of apparently falsifying evidence, the fact that a theory arises from a particular context is not sufficient to condemn it. Theories and paradigms must be accepted, modified or rejected on the basis of evidence.

An enthusiastic philosopher, of whose name we are not informed, had constructed a very satisfactory theory on some subject or other, and was not a little proud of it. "But the facts, my dear fellow," said his friend, "the facts do not agree with your theory."—"Don't they?" replied the philosopher, shrugging his shoulders, "then, tant pis pour les faits;"—so much the worse for the facts!

All things remarkable are surprisingly simple; albeit difficult to find.

And when were theories useless? I was a thinker, not a fighter, and the world was always in need of thoughts.

As the saying goes, ‘he who has a hammer sees everything as a nail’. If you approach a problem from a particular theoretical point of view, you will end up asking only certain questions and answering them in particular ways. You might be lucky, and the problem you are facing might be a ‘nail’ for which your ‘hammer’ is the most appropriate tool. But, more often than not, you will need to have an array of tools available to you. You are bound to have your favourite theory. There is nothing wrong with using one or two more than others — we all do. But please don’t be a man (or a woman) with a hammer — still less someone unaware that there are other tools available. To extend the analogy, use a Swiss army knife instead, with different tools for different tasks.­

Animals in pens have lots of time to develop theories", said the Cow, "I've heard more than one clever creature draw a connection between the rise of tiktokism and the erosion of traditional Animal labour. We weren't beasts of burden, but we were good reliable labourers. If we were made redundant in the workforce, it was only a matter of time before we'd be socially redundant too.

A philosopher's main task is to compulsively filibuster

A third reason scientists are reluctant to examine paranormal phenomena is that they appear to contradict known physical laws. What is the point of studying the impossible? Only a fool would waste his time. The problem of data in conflict with existing theory cannot be overstated. Arthur Eddington once said you should never believe any experiment until it has been confirmed by theory, but this humorous view has a reality that cannot be discounted.

A theory is like medicine (or government): often useless, sometimes necessary, always self-serving, and on occasion lethal. So it needs to be used with care, moderation and close adult supervision.

A theory is nothing but a tool to know the reality. If a theory contradicts reality, it must be discarded at the earliest.

Before yesterday I just thought on "IF", from there I build the theory "Everything is about IF", if you look deep enough you will find sense.

All good intellects have repeated, since Bacon’s time, that there can be no real knowledge but that which is based on observed facts. This is incontestable, in our present advanced stage; but, if we look back to the primitive stage of human knowledge, we shall see that it must have been otherwise then. If it is true that every theory must be based upon observed facts, it is equally true that facts cannot be observed without the guidance of some theory. Without such guidance, our facts would be desultory and fruitless; we could not retain them: for the most part we could not even perceive them.

Before an experiment can be performed, it must be planned—the question to nature must be formulated before being posed. Before the result of a measurement can be used, it must be interpreted—nature's answer must be understood properly. These two tasks are those of the theorist, who finds himself always more and more dependent on the tools of abstract mathematics. Of course, this does not mean that the experimenter does not also engage in theoretical deliberations. The foremost classical example of a major achievement produced by such a division of labor is the creation of spectrum analysis by the joint efforts of Robert Bunsen, the experimenter, and Gustav Kirchhoff, the theorist. Since then, spectrum analysis has been continually developing and bearing ever richer fruit.

Comics ... are sometimes four-legged and sometimes two-legged and sometimes fly and sometimes don't ... to employ a metaphor as mixed as the medium itself, defining comics entails cutting a Gordian-knotted enigma wrapped in a mystery ...

Chomsky's writings are 'classics' in Mark Twain's sense: something that everybody wants to have read and nobody wants to read.

Crime brings together honest men and concentrates them.

[Concerning Lyotard's ideology:]... Theory ought to be recognized as part of the problem, not as a potential solution.

Control Master Theory suggests that our psychological problems come about in much the same way: our decision to make ourselves unhappy because one or both of our parents were unhappy is just as altruistic as our friend's decision to run through flames to save his daughter.

...definitely believe that, there's got to be a spark to a place...to make it feel like a home...

Estoy más y más convencido de que los verdaderos revolucionarios deben percibir la revolución, debido a su naturaleza creativa y liberadora, como un acto de amor. Para mí, la revolución, que no era posible sin una teoría de la revolución -y, por ende, una ciencia- no es irreconciliable con el amor. Al contrario: la revolución es llevada a cabo por seres humanos, para alcanzar esta humanización. ¿Qué es, en efecto, el motivo más profundo que mueve a los individuos a convertirse en revolucionarios, si no es la deshumanización de la gente? La distorsión impuesta en la palabra "amor" por el mundo capitalista no puede prevenir que la revolución sea esencialmente amante en su carácter, ni puede prevenir que los revolucionarios afirmen su amor por la vida. Guevara (mientras que admitió que había "un riesgo de parecer ridículo") no tenía miedo de afirmarlo. "Déjenme decir, con el riesgo de parecer ridículo, que el verdadero revolucionario está guiado por un fuerte sentimiento de amor. Es imposible pensar una auténtica revolución sin esta cualidad.

Energetically speaking, antimatter is the mirror image of matter, so the two instantly cancel each other out if they come in contact. Keeping antimatter isolated from matter is a challenge, of course, because everything on earth is made of matter. The samples have to be stored without ever touching anything at all—even air.

Die Kunst des Rezensierens besteht nicht zuletzt darin, selbst über langweilige Bücher fesselnd zu schreiben.

Do not be afraid of the word 'theory'. Yes, it can sound dauntingly abstract at times, and in the hands of some writers can appear to have precious little to do with the actual, visual world around us. Good theory however, is an awesome thing. [...] But unless we actually use it, it borders on the metaphysical and might as well not be used at all.

—Então o senhor tem uma teoria? —Um detetive, M. Martin, sempre tem uma teoria. É o que se espera dele. Pessoalmente, não chamo de teoria. Digo que é uma ideiazinha. Essa é a primeira fase. —E a segunda? —Se a ideiazinha for acertada, então eu sei! É bastante simples, como se vê. —Gostaria que me dissesse qual é a sua teoria... ou ideiazinha.

Everything turns in circles and spirals with the cosmic heart until infinity. Everything has a vibration that spirals inward or outward — and everything turns together in the same direction at the same time. This vibration keeps going: it becomes born and expands or closes and destructs — only to repeat the cycle again in opposite current. Like a lotus, it opens or closes, dies and is born again. Such is also the story of the sun and moon, of me and you. Nothing truly dies. All energy simply transforms.

Every person should embrace those [dogmas] that he, being the best judge of himself, feels will do most to strengthen in him love of justice.

Every test of a theory, whether resulting in its corroboration or falsification, must stop at some basic statement or other which we decide to accept. If we do not come to any decision, and do not accept some basic statement or other, then the test will have led nowhere. But considered from a logical point of view, the situation is never such that it compels us to stop at this particular basic statement rather than at that, or else give up the test altogether. For any basic statement can again in its turn be subjected to tests, using as a touchstone any of the basic statements which can be deduced from it with the help of some theory, either the one under test, or another. This procedure has no natural end.

For starters, that’s a rather simple principle of Time Travel right there – and according to the pioneers of time travel, it’s one of the foundation stones of the Theory behind it. It’s something of a paradox – a mind-boggling annotation in the ever-puzzling and ever growing Anals of History. (Some readers may still be thinking that should be ‘Annals’ – however, the author of this work cannot be blamed for what you may think.)

Fine. You don't like my theory. Got it." "I like it. But it's kind of boring." "Well. So are you." "Probably why I like your theory.

[F]or a social theorist ignorance is more excusable than vagueness. Other investigators can easily show I am wrong if I am sufficiently precise. They will have much more difficulty showing by investigation what, precisely, I mean if I am vague. I hope not to be forced to weasel out with 'But I didn’t really mean that.' Social theorists should prefer to be wrong rather than misunderstood. Being misunderstood shows sloppy theoretical work.

Gut?” “General Unified Theory.” Kohler quipped. “The theory of everything.

From the dawn of civilization, human beings have tried to find out order in the chaotic world surrounding them. It has however never been easy to find a solution to explain a given system while being a part of that system. The best bet is to find out the most fundamental components within the system and building a theory round these. In other words, a theory that is able to describe the world in totality has to keep the number of basic postulates it depends upon to zero or near zero.

G. Stanley Hall, a creature of his times, believed strongly that adolescence was determined – a fixed feature of human development that could be explained and accounted for in scientific fashion. To make his case, he relied on Haeckel's faulty recapitulation idea, Lombroso's faulty phrenology-inspired theories of crime, a plethora of anecdotes and one-sided interpretations of data. Given the issues, theories, standards and data-handling methods of his day, he did a superb job. But when you take away the shoddy theories, put the anecdotes in their place, and look for alternate explanations of the data, the bronze statue tumbles hard. I have no doubt that many of the street teens of Hall's time were suffering or insufferable, but it's a serious mistake to develop a timeless, universal theory of human nature around the peculiarities of the people of one's own time and place.

Human potential is the ability of a person or humanity to put their theoretical abilities into practice

His entire presence was like gravity, impossible to forget, possible to believe in, a theory merged into a law.

Hence there is no free admission to the process of enlightenment - it is always paid at a psycho-traumatic cost. Only such individuals as always already bring along much more injury than could be caused by mere cognitive attacks on their narcissistic system have an apparently free backstage pass to it. Such candidates, like the highly talented of a special type, obtain their degree in wound studies free of charge. For them psychical sacrifices that only affect the cognitive immunity-shield appear to be forms of relief - for which reason they move about in the region of obscure theory like fish in water.

I confess that Fermat's Theorem as an isolated proposition has very little interest for me, for a multitude of such theorems can easily be set up, which one could neither prove nor disprove. But I have been stimulated by it to bring our again several old ideas for a great extension of the theory of numbers. Of course, this theory belongs to the things where one cannot predict to what extent one will succeed in reaching obscurely hovering distant goals. A happy star must also rule, and my situation and so manifold distracting affairs of course do not permit me to pursue such meditations as in the happy years 1796-1798 when I created the principal topics of my Disquisitiones arithmeticae. But I am convinced that if good fortune should do more than I expect, and make me successful in some advances in that theory, even the Fermat theorem will appear in it only as one of the least interesting corollaries. {In reply to Olbers' attempt in 1816 to entice him to work on Fermat's Theorem. The hope Gauss expressed for his success was never realised.}

I am apt, however, to entertain a Suspicion, that the World is still too young to fix any general stable Truths in Politics, which will remain true to the latest Posterity. We have not as yet had Experience of above three thousand Years; so that not only the Art of Reasoning is still defective in this Science, as well as in all others, but we even want sufficient Materials, upon which we can reason. 'Tis not sufficiently known, what Degrees of Refinement, either in Virtue or Vice, human Nature is susceptible of; nor what may be expected of Mankind from any great Revolution in their Education, Customs, or Principles.

I am now convinced that we have recently become possessed of experimental evidence of the discrete or grained nature of matter, which the atomic hypothesis sought in vain for hundreds and thousands of years. The isolation and counting of gaseous ions, on the one hand, which have crowned with success the long and brilliant researches of J.J. Thomson, and, on the other, agreement of the Brownian movement with the requirements of the kinetic hypothesis, established by many investigators and most conclusively by J. Perrin, justify the most cautious scientist in now speaking of the experimental proof of the atomic nature of matter, The atomic hypothesis is thus raised to the position of a scientifically well-founded theory, and can claim a place in a text-book intended for use as an introduction to the present state of our knowledge of General Chemistry.

If I keep observing the uranium, which means a little more than keeping my eyes on the pot on my desk and involves something akin to surrounding it with a whole system of Geiger counters, I can freeze it in such a way that it stops emitting radiation. Although Turing first suggested the idea as a theoretical construct, it turns out that it is not just mathematical fiction. Experiments in the last decade have demonstrated the real possibility of using observation to inhibit the progress of a quantum system.

I did think about a Ph.D. in computer science, but this is a time in industry where theory and practice are coming together in amazing ways. Yes, there's money, but what really interests me is that private-sector innovation happens faster. You can get more done and on a larger scale and have more impact. With all the start-ups out there, I think this is a time like the Renaissance. Not just one person doing great work, but so many feeding off one another. If you lived then, wouldn't you go out and paint?

If my nightmare is a culture inhabited by posthumans who regard their bodies as fashion accessories rather than the ground of being, my dream is a version of the posthuman that embraces the possibilities of information technologies without being seduced by fantasies of unlimited power and disembodied immortality, that recognizes and celebrates finitude as a condition of human being, and that understands human life is embedded in a material world of great complexity, one on which we depend for our continued survival.

If you wish to learn from the theoretical physicist anything about the methods which he uses, I would give you the following piece of advice: Don't listen to his words, examine his achievements. For to the discoverer in that field, the constructions of his imagination appear so necessary and so natural that he is apt to treat them not as the creations of his thoughts but as given realities.

If there are infinite dimensions then there would be infinite alternate realities and if there are infinite alternate realities we would exist in almost all of them that would make all of us omnipresent...
