Theoretical and experimental physicists are now studying nothing at all-the vacuum. But that nothingness contains all of being.
[T]he shaman treats all realities as subjective, much like some modern theoretical physicists are beginning to do. In such a viewpoint the question of whether an experience is real or not makes no sense, because the answer is yes and no, depending on your point of view.
Although I am even now still a layman in the area of mathematics, and although I lack theoretical knowledge, the mathematicians, and in particular the crystallographers, have had considerable influence on my work of the last twenty years. The laws of the phenomena around us--order, regularity, cyclical repetition, and renewals--have assumed greater and greater importance for me. The awareness of their presence gives me peace and provides me with support. I try in my prints to testify that we live in a beautiful and orderly world, and not in a formless chaos, as it sometimes seems.
Thus not only the mental and the material, but the theoretical and the practical in the mathematical world, are brought into more intimate and effective connection with each other.
A theoretical system does not merely state facts which have been observed and that logically deducible relations to other facts which have also been observed.
Is it needy? It's not. We don't need each other. We just really, really enjoy each other. And we're good together. We're good people together. And I have the funniest feeling. I can really, truly touch this all, this happiness and the sadness too, I can trace all of it with my fingers. It isn't theoretical or distant. This feels like me. This is me. I love him, and, for the first time in a relationship, I also like me. Every time he says "I love you," I answer, "I believe you.
I doubt if there is a single field of study so theoretical, so remote from what is laughingly called everyday life, that it may not one day produce something that will shake the world.
I should emphasize this, to keep well-meaning but misguided multiculturalists at bay: the theoretical entities in which these tribal people frankly believe — the gods and other spirits — don't exist. These people are mistaken, and you know it as well as I do. It is possible for highly intelligent people to have a very useful but mistaken theory, and we don't have to pretend otherwise in order to show respect for these people and their ways.
Special emphasis should be laid on this intimate interrelation of general statements about empirical fact with the logical elements and structure of theoretical systems.
There is not some glorious theoretical synthesis of capitalism that you can write down in a book and follow. You have to grope your way
Zen has no theory. It is a non-theoretical approach into reality. It has no doctrine and no dogma - hence it has no church, no priest, no pope.
The theoretical postulate of all diplomatic discussion between nations is the assumed willingness of every nation to do justice.
The theoretical fruits of deliberate oversimplification through idealization are not to be denied... Reality in all its messy particularity is too complicated to theorize about, taken straight. The issue is, rather (since every idealization is a strategic choice), which idealizations might really shed some light... which will just land us... diverting fairy tales.
The longing to behold this pre-established harmony [of phenomena and theoretical principles] is the source of the inexhaustible patience and perseverance with which Planck has devoted himself ... The state of mind which enables a man to do work of this kind is akin to that of the religious worshiper or the lover; the daily effort comes from no deliberate intention or program, but straight from the heart.
I know a few women younger than me who have careers and children, and so the burgeoning career and family happen at the same time. A few have said something like, "During dating, he was all about feminism. But now I have to ask him to help with the children, I have to ask him to do the dishes, and every time he does, it's like a favor. Where's the feminist I married?" That's theoretical feminism, not practical feminism. I don't think we're all where we need to be. I don't know if we will be in my lifetime. Life is imperfect. But interesting.
Who is writing these screenwriting books? Not actually writing for the studios in Hollywood. These are people that have one or a half of a credit on maybe one movie, or none. So they're all theoretical.
The raging monster upon the land is population growth. In its presence, sustainability is but a fragile theoretical construct. To say, as many do, that the difficulties of nations are not due to people, but to poor ideology and land-use management is sophistic.
I'm a pluralist about perspectives on literature. There seem to me to be all sorts of illuminating ways of responding to major literary works, some of them paying considerable attention to context, others applying various theoretical ideas, yet others focusing on details of language, or linking the work to the author's life, or connecting it with other works.
We commit not only theoretical error but also moral wrong in objectifying ourselves or other rational beings, ignoring their capacities for free action and communicative interaction with us.
As a constellation, theoretical thought circles the concept it would like to unseal, hoping that it may fly open like the lock of a well-guarded safe-deposit box: in response, not to a single key or a single number, but to a combination of numbers
The panorama-city is a 'theoretical' (that is, visual) simulacrum, in short a picture, whose condition of possibility is an oblivion and a misunderstanding of practices.
Your remarks upon chemical notation with the variety of systems which have arisen, &c., &c., had almost stirred me up to regret publicly that such hindrances to the progress of science should exist. I cannot help thinking it a most unfortunate thing that men who as experimentalists & philosophers are the most fitted to advance the general cause of science & knowledge should by promulgation of their own theoretical views under the form of nomenclature, notation, or scale, actually retard its progress.
If the highest things are unknowable, then the highest capacity or virtue of man cannot be theoretical wisdom.
Business schools make a fortune forcing their students to take in a HUGE amount of information. The majority of it is theoretical. The majority of that is useless.
The work is what it is and hopefully it's seen as feminist work, or feminist-advised work, but I'm not going to go around espousing theoretical bullshit about feminist stuff.
We do have tendency, now in biology especially to make up stories, to make theoretical biology a kind of game, in fact we have game theory in biology which is meant to use the theory of games to make predictions or explain things.
In some ways I'm a frustrated scientist or mathematician. The amount of times I've thought I'd go back to university and do theoretical physics because I like the big questions, but really I know now that that's not quite me. What's me is to do it in novels.
Our relationships as experimentalists with theoretical physicists should be like those with a beautiful woman - we should accept with gratitude any favours she offers, but we should not expect too much nor believe all that is said.
If the experimental physicist has already done a great deal of work in this field, nevertheless the theoretical physicist has still hardly begun to evaluate the experimental material which may lead him to conclusions about the structure of the atom.
Any philosophical and theoretical assurance that laughter is unique to the human being becomes somewhat unsure when one turns to the anthropological literature.
If we analyse the supernova data by assuming the Copernican principle is correct and get out something unphysical, I think we should start questioning the Copernican principle…. Whatever our theoretical predilections, they will in the end have to give way to the observational evidence.
It is natural that a man should consider the work of his hands or his brain to be useful and important. Therefore nobody will object to an ardent experimentalist boasting of his measurements and rather looking down on the 'paper and ink' physics of his theoretical friend, who on his part is proud of his lofty ideas and despises the dirty fingers of the other. Experiment and Theory in Physics
The ultimate arbiter of truth is experiment, not the comfort one derives from one's a priori beliefs, nor the beauty or elegance one ascribes to one's theoretical models.
Science has been effective at furthering our understanding of nature because the scientific ethos is based on three key principles: (1) follow the evidence wherever it leads; (2) if one has a theory, one needs to be willing to try to prove it wrong as much as one tries to prove that it is right; (3) the ultimate arbiter of truth is experiment, not the comfort one derives from one's a priori beliefs, nor the beauty or elegance one ascribes to one's theoretical models.
If philosophy is practice, a demand to know the manner in which its history is to be studied is entailed: a theoretical attitude toward it becomes real only in the living appropriation of its contents from the texts.
The pace of science forces the pace of technique. Theoretical physics forces atomic energy on us; the successful production of the fission bomb forces upon us the manufacture of the hydrogen bomb. We do not choose our problems, we do not choose our products; we are pushed, we are forced -- by what? By a system which has no purpose and goal transcending it, and which makes man its appendix.
[Gauss calculated the elements of the planet Ceres] and his analysis proved him to be the first of theoretical astronomers no less than the greatest of 'arithmeticians.'
Responsible Development is the style of development I aspire to now. It can be summarized by answering the question, How would I develop if it were my money? I'm amazed how many theoretical arguments evaporate when faced with this question.
The fact that Science walks forward on two feet, namely theory and experiment, is nowhere better illustrated than in the two fields for slight contributions to which you have done me the great honour of awarding the the Nobel Prize in Physics for the year 1923. Sometimes it is one foot that is put forward first, sometimes the other, but continuous progress is only made by the use of both-by theorizing and then testing, or by finding new relations in the process of experimenting and then bringing the theoretical foot up and pushing it on beyond, and so on in unending alterations.
Theoretically, you can make, obviously, a powerful argument that centuries of slavery, Jim Crow, discrimination are the primary cause for all those gaps. That those were wrongs done to the black community as a whole, and black families specifically, and that in order to close that gap, a society has a moral obligation to make a large, aggressive investment, even if it's not in the form of individual reparations checks, but in the form of a Marshall Plan, in order to close those gaps. It is easy to make that theoretical argument.
To avert the danger [posed by theory] to life, Nietzsche could choose one of two ways: he could insist on the strictly esoteric character of the theoretical analysis of life - that is, restore the Platonic notion of the noble delusion - or else he could deny the possibility of theory proper and so conceive of thought as essentially subservient to, or dependent on, life or fate... If not Nietzsche himself, at any rate his successors [Heidegger] adopted the second alternative.
So much of what we said sounded crazy, yet none of it was false... as if two theoretical physicists stood on stage to say that when we travel near lightspeed, we get younger than nontravellers; that a mile of space next to the sun is differnt than a mile of space next to the earth because the sun-mile space is curved more than the the earth-mile. Silly ideas, worth the admission price in smiles, but they're true. Is high-energy physics interesting because it's true or because it's crazy?
The only purpose of education is to teach a student how to live his life-by developing his mind and equipping him to deal with reality. The training he needs is theoretical, i.e., conceptual. He has to be taught to think, to understand, to integrate, to prove. He has to be taught the essentials of the knowledge discovered in the past-and he has to be equipped to acquire further knowledge by his own effort.
Faith may always be acquired. Whoso is devoid of faith, and desires to have it, may acquire it by living for a few days (sometimes for a few hours only) as though he already possessed it. It is by practical, not theoretical, religion, that men transform their lives.
One important idea is that science is a means whereby learning is achieved, not by mere theoretical speculation on the one hand, nor by the undirected accumulation of practical facts on the other, but rather by a motivated iteration between theory and practice.
He was bookish, she was not; he was theoretical, she political. She called a rose a rose. He called it an accumulation of cultural and biological constructions circulating around the mutually attracting binary poles of nature/artifice.
The career of a young theoretical physicist consists of treating the harmonic oscillator in ever-increasing levels of abstraction.
At present, when the prevailing forms of society have become hindrances to the free expression of human powers, it is precisely the abstract branches of science, mathematics and theoretical physics, which ... offer a less distorted form of knowledge than other branches of science which are interwoven with the pattern of daily life, and the practicality of which seemingly testifies to their realistic character.
That's all very well as an abstract moral principle, Avril, a coffee-table theoretical construct, but there's no denying the sheer gratuitous pleasure to be derived from seeing members of the ruling class in pain and torment.
