House Md if Theres Any Chance That I Can Walk Again

The great extension of our experience in contempo years has brought light to the insufficiency of our simple mechanical conceptions and, as a consequence, has shaken the foundation on which the customary interpretation of ascertainment was based.

Niels Henrik David Bohr (7 Oct 1885 – 18 November 1962) was a Danish physicist. He received the Nobel Prize for Physics in 1922 for his contributions which were essential to modern understandings of diminutive structure and quantum mechanics.

Quotes [edit]

The word "reality" is too a discussion, a word which we must learn to apply correctly.

Nosotros are all agreed that your theory is crazy. The question that divides us is whether it is crazy enough to have a chance of being right.

Physics is to be regarded non and then much as the study of something a priori given, but rather as the evolution of methods of ordering and surveying human feel.

It is wrong to think that the task of physics is to discover out how nature is. Physics concerns what we can say about nature...

Information technology is a groovy compassion that human beings cannot find all of their satisfaction in scientific contemplativeness.

Some subjects are so serious that one can only joke about them.

• The grand discoveries which scientific experiment yielded at and virtually the plough of the century, in which investigators in many countries took an eminent role and which were destined all unexpectedly to give united states a fresh insight into the construction of atoms, were due in the first instance, as all are aware, to the work of the great investigators of the English language schoolhouse, Sir Joseph Thomson and Sir Ernest Rutherford, who have inscribed their names on the tablets of the history of scientific research as distinguished witnesses to the truth that imagination and acumen are capable of penetrating the crowded mass of registered experience and of revealing Nature's simplicity to our gaze.

[edit]

The fact that religions through the ages have spoken in images, parables, and paradoxes means simply that at that place are no other ways of grasping the reality to which they refer. Only that does not mean that it is not a genuine reality.

Nowadays, the individual seems to exist able to choose the spiritual framework of his thoughts and actions quite freely, and this freedom reflects the fact that the boundaries betwixt the various cultures and societies are beginning to become more fluid. Simply even when an individual tries to attain the greatest possible degree of independence, he will still be swayed by the existing spiritual structures — consciously or unconsciously.

Statements of Bohr after the Solvay Conference of 1927, as quoted in Physics and Beyond (1971) past Werner Heisenberg

• I feel very much like Dirac: the thought of a personal God is foreign to me. Just we ought to remember that faith uses linguistic communication in quite a different fashion from scientific discipline. The language of organized religion is more closely related to the language of poetry than to the language of science. True, we are inclined to think that science deals with data about objective facts, and poetry with subjective feelings. Hence we conclude that if organized religion does indeed deal with objective truths, information technology ought to adopt the aforementioned criteria of truth every bit scientific discipline. Simply I myself find the division of the world into an objective and a subjective side much too arbitrary. The fact that religions through the ages have spoken in images, parables, and paradoxes means but that at that place are no other ways of grasping the reality to which they refer. But that does not mean that it is not a genuine reality. And splitting this reality into an objective and a subjective side won't get us very far.

• I consider those developments in physics during the last decades which have shown how problematical such concepts every bit "objective" and "subjective" are, a dandy liberation of thought. The whole affair started with the theory of relativity. In the by, the statement that 2 events are simultaneous was considered an objective assertion, one that could exist communicated quite but and that was open up to verification past any observer. Today we know that 'simultaneity' contains a subjective element, inasmuch as two events that appear simultaneous to an observer at rest are non necessarily simultaneous to an observer in motion. However, the relativistic description is also objective inasmuch as every observer tin can deduce by calculation what the other observer volition perceive or has perceived. For all that, we have come a long manner from the classical platonic of objective descriptions.
  In quantum mechanics the departure from this ideal has been even more than radical. We can nevertheless use the objectifying linguistic communication of classical physics to brand statements near appreciable facts. For instance, we tin say that a photographic plate has been blackened, or that cloud droplets take formed. But we can say cypher about the atoms themselves. And what predictions we base on such findings depend on the way nosotros pose our experimental question, and hither the observer has freedom of choice. Naturally, information technology still makes no divergence whether the observer is a homo, an animal, or a piece of appliance, just it is no longer possible to make predictions without reference to the observer or the means of observation. To that extent, every physical process may be said to take objective and subjective features. The objective globe of nineteenth-century science was, as we know today, an ideal, limiting case, but non the whole reality. Admittedly, fifty-fifty in our futurity encounters with reality we shall have to distinguish betwixt the objective and the subjective side, to make a division between the two. But the location of the separation may depend on the mode things are looked at; to a sure extent information technology can exist called at will. Hence I tin can quite understand why we cannot speak about the content of religion in an objectifying language. The fact that unlike religions endeavor to express this content in quite singled-out spiritual forms is no real objection. Perhaps we ought to look upon these different forms as complementary descriptions which, though they exclude ane another, are needed to convey the rich possibilities flowing from human'south relationship with the central order.

• In mathematics nosotros tin can take our inner distance from the content of our statements. In the last assay mathematics is a mental game that we can play or non play every bit we choose. Faith, on the other hand, deals with ourselves, with our life and death; its promises are meant to govern our actions and thus, at least indirectly, our very existence. We cannot merely look at them impassively from the outside. Moreover, our attitude to religious questions cannot exist separated from our attitude to society. Even if organized religion arose as the spiritual structure of a particular man lodge, it is arguable whether it has remained the strongest social molding forcefulness through history, or whether lodge, in one case formed, develops new spiritual structures and adapts them to its particular level of knowledge. Nowadays, the private seems to be able to choose the spiritual framework of his thoughts and deportment quite freely, and this freedom reflects the fact that the boundaries between the various cultures and societies are commencement to become more fluid. But even when an individual tries to achieve the greatest possible degree of independence, he will still exist swayed past the existing spiritual structures — consciously or unconsciously. For he, too, must exist able to speak of life and death and the human condition to other members of the society in which he's chosen to alive; he must educate his children according to the norms of that society, fit into its life. Epistemological sophistries cannot maybe help him attain these ends. Hither, too, the relationship between critical thought nearly the spiritual content of a given religion and activeness based on the deliberate acceptance of that content is complementary. And such acceptance, if consciously arrived at, fills the private with strength of purpose, helps him to overcome doubts and, if he has to endure, provides him with the kind of solace that but a sense of being sheltered under an all-embracing roof can grant. In that sense, religion helps to make social life more harmonious; its most of import task is to remind us, in the language of pictures and parables, of the wider framework within which our life is fix.

    Once I tried to teach some breakthrough mechanics to a form of police force students, philosophers, and art historians. As an advertisement for the grade I put together the most sensational quotations I could collect from the virtually administrative practitioners of the subject. Heisenberg was a goldmine: "The concept of the objective reality of the unproblematic particles has thus evaporated..."; "the thought of an objective existent globe whose smallest parts exist objectively in the same sense as stones or trees be, independently of whether or not nosotros observe them ... is impossible ..." Feynman did his office too: "I think I can safely say that nobody understands quantum mechanics." Only I failed to turn upwardly anything comparable in the writings of Bohr. Others attributed spectacular remarks to him, but he seemed to take pains to avoid whatsoever hint of the dramatic in his own writings. You don't pack them into your classroom with "The indivisibility of quantum phenomena finds its consequent expression in the circumstance that every definable subdivision would crave a change of the experimental organization with the appearance of new individual phenomena," or "the wider frame of complementarity straight expresses our position every bit regards the account of fundamental properties of thing presupposed in classical physical description merely outside its telescopic."

    I was therefore on the lookout for nuggets when I sat downwardly to review these 3 volumes – a reissue of Bohr's collected essays on the revolutionary epistemological character of the quantum theory and on the implications of that revolution for other scientific and non-scientific areas of endeavor (the originals first appeared in 1934, 1958, and 1963.) But the near radical statement I could find in all three books was this: "...physics is to be regarded not so much as the written report of something a priori given, merely rather as the development of methods for ordering and surveying homo experience." No nuggets for the nonscientist.

Quotes about Bohr [edit]

Alphabetized by author

• Bohr seemed to call back that he had solved this question. I could not find his solution in his writings. But in that location was no dubiety that he was convinced that he had solved the problem and, in then doing, had not just contributed to atomic physics, just to epistemology, to philosophy, to humanity in general. And there are amazing passages in his writings in which he is sort of patronizing to the ancient Far Eastern philosophers, near saying that he had solved the problems that had defeated them. It's an extraordinary thing for me—the character of Bohr—absolutely puzzling. I similar to speak of two Bohrs: one is a very pragmatic swain who insists that the apparatus is classical, and the other is a very arrogant, pontificating man who makes enormous claims for what he has done.
  • John S. Bell, quoted in Jeremy Bernstein, Quantum Profiles (1991), John Stewart Bong: Quantum Engineer

• One of the favorite maxims of my father was the distinction between the two sorts of truths, profound truths recognized by the fact that the opposite is also a profound truth, in contrast to trivialities where opposites are obviously cool.
  • Hans Henrik Bohr, writing about his father in "My father" in Niels Bohr - His Life and Work As Seen Past His Friends and Colleagues (1967), Southward. Rozental, ed.

• If quantum theory has any philosophical importance at all, it lies in the fact that it demonstrates for a unmarried, sharply defined science the necessity of dual aspects and complementary considerations. Niels Bohr has discussed this question with respect to many applications in physiology, psychology, and philosophy in full general.
  • Max Built-in in Natural Philosophy of Cause and Chance (1949) ch. 10, p. 127

• Non ofttimes in life has a human being caused me such joy by his mere presence every bit you did.
  • Albert Einstein in a letter to Bohr (1920)

• It is practically impossible to describe Niels Bohr to a person who has never worked with him. Probably his most feature property was the slowness of his thinking and comprehension. When, in the late twenties and early thirties, the author of this volume was one of the "Bohr boys" working in his Institute in Copenhagen on a Carlsberg (the best beer in the world!) fellowship, he had many a adventure to find it. In the evening, when a handful of Bohr's students were "working" in the Paa Blegdamsvejen Constitute, discussing the latest issues of the quantum theory, or playing Ping-pong on the library table with coffee cups placed on it to make the game more than hard, Bohr would appear, complaining that he was very tired, and would like to "do something." To "do something" inevitably meant to get to the movies, and the only movies Bohr liked were those called The Gun Fight at the Lazy Gee Ranch or The Lone Ranger and a Sioux Girl. Merely it was hard to go with Bohr to the movies. He could not follow the plot, and was constantly asking u.s., to the great annoyance of the rest of the audience, questions like this: "Is that the sister of that cowboy who shot the Indian who tried to steal a herd of cattle belonging to her brother-in-constabulary?" The same slowness of reaction was apparent at scientific meetings. Many a fourth dimension, a visiting immature physicist (most physicists visiting Copenhagen were young) would deliver a brilliant talk well-nigh his contempo calculations on some intricate problem of the quantum theory. Everybody in the audience would empathize the argument quite conspicuously, but Bohr wouldn't. And so everybody would kickoff to explain to Bohr the uncomplicated betoken he had missed, and in the resulting turmoil everybody would stop understanding anything. Finally, after a considerable menstruation of fourth dimension, Bohr would brainstorm to understand, and information technology would turn out that what he understood nigh the trouble presented by the company was quite unlike from what the visitor meant, and was correct, while the company's estimation was wrong.
  • George Gamow on Niels Bohr in "The Peachy Physicists from Galileo to Einstein" (1961) pg. 237

• I remember discussions with Bohr which went through many hours till very late at night and ended almost in despair; and when at the end of the word I went alone for a walk in the neighbouring park I repeated to myself once more and again the question: Tin can nature possibly be and so cool as it seemed to us in these atomic experiments?
  • Werner Heisenberg in Physics and Philosophy (1958)

• The first thing Bohr said to me was that information technology would merely then be profitable to work with him if I understood that he was a dilettante. The but way I knew to react to this unexpected statement was with a polite smiling of atheism. But plainly Bohr was serious. He explained how he had to approach every new question from a starting point of full ignorance. It is perhaps better to say that Bohr's force lay in his formidable intuition and insight rather than erudition.
  • Abraham Pais, in testimony in Niels Bohr : His Life and Piece of work as Seen past His Friends and Colleagues (1967) edited by Stefan Rozental, p. 218; subsequently in his own work, Niels Bohr's Times : In Physics, Philosophy, and Polity (1991)

• When asked whether the algorism of quantum mechanics could exist considered as somehow mirroring an underlying quantum world, Bohr would answer, "There is no quantum world. There is only an abstruse quantum concrete description. Information technology is wrong to remember that the job of physics is to find out how nature is. Physics concerns what we can say virtually nature." Bohr felt that every stride in the development of physics has strengthened the view that the problem of establishing an unambiguous description of nature has only i solution. He regarded all attempts to replace our elementary concepts or to introduce a new logic to account for the peculiarities of quantum phenomena as not only unnecessary but likewise incompatible with our most fundamental weather, since we are suspended in a unique language.

    • To my neat pleasure, Victor Weisskopf was sitting in his usual place in the front row, smile approvingly up at me. (It's surprising how much such encouragement from such a source can improve the quality of a talk.) His smiles continued right up to the moment when I read the Petersen quotation. No sooner had I finished reading it than Viki was on his feet. "That's outrageous," he proclaimed. "Bohr couldn't possibly take said anything like that!" Somewhat taken aback by this sudden flip from approbation to condemnation, I feebly protested that I wasn't attributing information technology to Bohr, but to Aage Petersen's memory of Bohr.
