Academics From Germany

"When a mixture of 1,3-butadiene and ethene is heated in the gas phase, a remarkable reaction takes place in which cyclohexene is formed by the simultaneous generation of two new carbon – carbon bonds. This is the simplest example of the Diels-Alder reaction, in which a conjugated diene adds to an alkene to yield cyclohexene derivatives. The Diels-Alder reaction is in turn a special case of the more general class of cycloaddition reactions between psystems, the products of which are called cycloadducts."

"It will rightly be asked: What is the synthetic principle on which this obviously highly important product of y-methylcyclopentenophenanthrene is built up in nature, and why is it that this particular type which, as founda tion of many substances indispensable to life and of extreme physiological and biological importance, plays such a vital role in the vegetable and animal kingdoms? However, the time has not yet come when we can give an answer to questions so fundamental and so important to an understanding of the workings of Nature. But I am firmly convinced that this problem - like all others - will eventually be solved."

"A tenor is not a man but a disease."

"Your tone sounds like roast-beef gravy running through a sewer."

"The editor of this selection from Chopin’s Pianoforte Studies has, however, no such intention; on the contrary. he wishes to make some of them, which owing to their difficulty have hitherto remained unpopularised, more accessible, particularly to the amateur, by pointing out the way to their correct study. And thus, on the basis of the technical facility to be acquired through these pieces, to enable even the non-professional to enjoy a more intimate acquaintance with those works of the classical romanticist, which, though representing the best and most undying side of his genius, have found till now but a small, though daily increasing circle of admirers; for the “Ladies’-Chopin”, which for forty years has blossomed in the pale and sickly rays of dilettantism; the “talented, languishing, Polish youth” to whom the most modest place on the Parnassus of musical literature was denied by the amateurish criticism of German professors, is as little the genuine entire Chopin, as is the Beethoven of “Adelaide” and the “Moonlight Sonata”, the god of Symphony. Truly a span of time must yet elapse before the matured and manly Chopin, the author of the two Sonatas, the 3rd and 4th Scherzos, the 4th Ballade, the Polonaise in F# minor, the later Mazurkas and Nocturnes etc., will be completely and generally appreciated at his full worth. At the same time much may be done by preparing and clearing the way; and one of the best means towards this end is sifting the material, and replacing favourite and unimportant works, by those less known though more important."

"Here Chopin has the conviction that he has lost his power of expression. With the determination to discover whether his brain can still originate ideas, he strikes his head with a hammer (here the sixteenths and thirty-seconds are to be carried out in exact time, indicating a double stroke of the hammer). In the third and fourth measures on can hear the blood trickle (trills in the left hand). He is desperate at finding no inspiration (fifth measure); he strikes again with the hammer and with greater force (thirty-second notes twice in succession during the crescendo). In the key of A flat he finds his powers again. Appeased, he seeks his former key and closes contentedly."

"In the intellectual market the quantity of the demand rises in proportion to that of the supply, but its quality does not keep pace with this increase. For example, the Old Testament of pianoforte players, Bach’s “Das wohltemperierte Klavier” is perhaps in almost as many hands as the New Testament, Beethoven’s Pianoforte Sonatas, but in few more heads than it was in former years, when it could only be had for six times the present price. Doubtless, its leaves are somewhat oftener turned over, but now, as then, about the sixth part, likely enough just the first sixth, is all that is studied in the real meaning of the word. Here truly is little more gained than a merely superficial acquaintance with the great father of German music."

"I am not a vegetarian."

"In the beginning was rhythm."

"Always conduct with the score in your head, not your head in the score."

"It was von Bülow more than anybody else who by the force of personality, skill, perseverance and rasplike intelligence established the supremacy of the German school for several decades. He was the archetype of the German Tonkünstler: demanding, dictatorial, testy, chauvinistic, convinced of his superiority, possessed of a fine musical culture plus executive ability and leadership, and also of virulent, pathological anti-Semitism..."

"Through his life he cut a wide swath through Europe and American, terrifying and amazing people with his intellect, his temper, his sarcasm (Brahms once said, "Hans von Bülow's praise smarts like salt in the eyes so that tears run") and his undisputed musicianship. His temper was legendary. As a teacher he was a holy terror. Often he would take over Liszt's classes and attempt to weed them out. He told one of Liszt's young ladies that she should be swept out of the class "not with a broom but a broomstick. Go home!" To a girl who played Liszt's Mazeppa, the Étude that describes the galloping of a horse, von Bülow's compliment was that her only qualification for her playing the work was that she had the soul of a horse."

"Positivism, with its principle that ‘a law is a law’, has in fact rendered the German legal profession defenceless against statutes that are arbitrary and criminal. Positivism is, moreover, in and of itself wholly incapable of establishing the validity of statutes. It claims to have proved the validity of a statute simply by showing that the statute had sufficient power behind it to prevail. But while power may indeed serve as a basis for the ‘must’ of compulsion, it never serves as a basis for the ‘ought’ of obligation or for legal validity. Obligation and legal validity must be based, rather, on a value inherent in the statute."

"To be sure, one value comes with every positive-law statute without reference to its content: Any statute is always better than no statute at all, since it at least creates legal certainty. But legal certainty is not the only value that law must effectuate, nor is it the decisive value. Alongside legal certainty, there are two other values: purposiveness and justice. In ranking these values, we assign to last place the purposiveness of the law in serving the public benefit."

"Of course it is true that the public benefit, along with justice, is an objective of the law. And of course laws have value in and of themselves, even bad laws: the value, namely, of securing the law against uncertainty."

"The most conspicuous characteristic of Hitler’s personality, which became through his influence the pervading spirit of the whole of National Socialist ‘law’ as well, was a complete lack of any sense of truth or any sense of right and wrong."

"It is the professional duty of the judge to validate the law’s claim to validity, to sacrifice his own sense of the right to the authoritative command of the law, to ask only what is legal and ask not if it is also just."

"The concept of law can be defined only as the reality tending toward the idea of law."

"The validity of demonstrably wrong law cannot conceivably be justified. However, any answer to the question of the purpose of law other than by enumerating the manifold partisan views about it has proved impossible— and it is precisely on that impossibility of any natural law, and on that alone, that the validity of positive law may be founded. At this point relativism, so far only the method of our approach, enters our system as a structural element. Ordering their living together cannot be left to the legal notions of the individuals who live together, since these different human beings will possibly issue contradictory directions. Rather, it must be uniformly governed by a transindividual authority. Since, however, in the relativistic view of reason and science are unable to fulfill that task, will and power must undertake it. If no one is able to determine what is just, somebody must lay down what is to be legal."

"Philosophy is not to relieve one of decisions, but to confront him with decisions. It is to make life not easy but, on the contrary, problematical."

"As it is the essence of justice ultimately to shape those relations in the sense of equality, so it is essential to the legal precept in its meaning to be directed toward equality, to claim to be susceptible of generalization or to be general in character."

"Concepts such as legal subject and legal object, legal relation and legal wrong, and indeed the very concept of law itself, are not accidental possessions of several or all legal orders but are necessary prerequisites if any legal order is to be understood as legal."

"This view of a law and of its validity (we call it the positivistic theory) has rendered jurists and the people alike defenceless against arbitrary, cruel, or criminal laws, however extreme they might be. In the end, the positivistic theory equates law with power; there is law only where there is power."

"Because a judgement on the truth or error of the differing convictions in law is impossible, and because on the other hand a uniform law for all citizens is necessary, the law-giver faces the task of cleaving with a stroke of the sword the Gordian knot which jurisprudence cannot untangle. Since it is impossible to ascertain what is just, it must be decided what is lawful. In lieu of an act of truth (which is impossible) an act of authority is required. Relativism leads to positivism."

"Beauty is but the cloak of happiness. Where joy tarries, there also is beauty."

"Everything purposeful is meaningless, and everything meaningful is purposeless."

"Thus, the United States in 1917 went to war against Germany in sincere indignation because the newspapers had told them that Prussian "militarism" was rioting in devilish atrocities as it attempted to conquer the world. Of course, these transparent lies were published in the daily rags because the ruling lords of Mammon knew that American intervention in Europe would fatten their coffers. Thus, whereas the Americans thought that they were fighting for such high-minded slogans as “liberty" and "justice," they were actually fighting to stuff the money bags of the big bankers. These "free citizens" are, in fact, mere marionettes; their freedom is imaginary, and a brief glance at American work-methods and leisure-time entertainments is enough to prove conclusively that l’homme machine is not merely imminent: it is already the American reality."

"I have never endorsed the claim that the Nazi big-wigs belonged to a superior race. However, I must also add that I have consistently refused to accept the claim of another such race as the chosen people. The arrogance is identical in both cases, but with this important distinction: after waging war against mankind for more than three thousand years, Judaism has finally achieved total victory over all nations of the earth."

"The great masses, who have never been, in the history of mankind, more subject to hypnotic suggestion than they are right now, have become the puppets of the “public opinion” that is engineered by the newspapers in the service, it need hardly be emphasized, of the reigning powers of finance. What is printed in the morning editions of the big city newspapers is the opinion of nine out of ten readers by nightfall. The United States of America, whose more rapid “progress” enables us to predict the future on a daily basis, has pulled far ahead of the pack when it comes to standardizing thought, work, entertainment, etc."

"Christianity is the war against sleep and dream."

"The profundity of truth varies with the seeing power of the spirit which seeks it."

"Many first possess wealth, and are then possessed by it."

"A man who cannot climb a tree will boast of never having fallen out of one."

"The lukewarm baths at 25 to 27° serve to arouse the slumbering sensibility of fibre in the apparent dead (frozen, drowned, suffocated) which benumbed the sensation of the nerves. Though only palliative, still they often prove themselves sufficiently active, especially when given in conjunction with coffee and rubbing with the hands. They may give homœopathic aid in cases where the irritability is very unevenly distributed and accumulated too unevenly in some organs as is the case in certain hysteric spasms and infantile convulsions. In the same way, cold baths 10 to 6° in persons cured medically of chronic diseases and with deficiency of vital heat, act as an homœopathic aid. By instantaneous and later with repeated immersions they act as a palliative restorative of the tone of the exhausted fibre. For this purpose, such baths are to be used for more than momentary duration, rather for minutes and of gradually lowered temperature, they are a palliative, which, since it acts only physically has no connection with the disadvantage of a reverse action to be feared afterwards, as takes place with dynamic medicinal palliatives."

"If the physician clearly perceives what is to be cured in diseases, that is to say, in every individual case of disease (knowledge of disease, indication), if he clearly perceives what is curative in medicines, that is to say, in each individual medicine (knowledge of medical powers), and if he knows how to adapt, according to clearly defined principles, what is curative in medicines to what he has discovered to be undoubtedly morbid in the patient, so that the recovery must ensue - to adapt it, as well in respect to the suitability of the medicine most appropriate according to its mode of action to the case before him (choice of the remedy, the medicine indicated), as also in respect to the exact mode of preparation and quantity of it required (proper dose), and the proper period for repeating the dose; - if, finally, he knows the obstacles to recovery in each case and is aware how to remove them, so that the restoration may be permanent, then he understands how to treat judiciously and rationally, and he is a true practitioner of the healing art ."

"In 1908 the famous mathematician Minkowski made a remarkable discovery concerning the Lorentz formulae. He showed that, although each observer has his own private space and private time, a public concept which is the same for all observers can be formed by combining space and time as a kind of 'distance' by multiplying it by the velocity of light, c; in other words, with any time interval we can associate a definite spatial interval, namely the distance which light can travel in empty space in that period. If, according to a particular observer, the difference in time between any two events is T, this associated spatial interval is cT. Then, if R is the space-distance between these two events, Minkowski showed that the difference of the squares of cT and R has the same value for all observers in uniform relative motion. The square root of this quantity is called the space-time interval between two events. Hence, although time and three-dimensional space depend on the observer, this new concept of space-time is the same for all observers."

"According to the special theory there is a finite limit to the speed of causal chains, whereas classical causality allowed arbitrarily fast signals. Foundational studies... soon revealed that this departure from classical causality in the special theory is intimately related to its most dramatic consequences: the relativity of simultaneity, time dilation, and length contraction. By now it had become clear that these kinematical effects are best seen as consequences of Minkowski space-time, which in turn incorporates a nonclassical theory of causal structure. However, it has not widely been recognized that the converse of this proposition is also true: the causal structure of Minkowski space-time contains within itself the entire geometry (topoligical and metrical structure) of Minkowski space-time. ...The problem of the independence of topological and metrical structures of space-time was clearly recognized by early writers on relativity such as Russell (1954) and, of course, Eddington..."

"Minkowski calls a spatial point existing at a temporal point a world point. These coordinates are now called 'space-time coordinates'. The collection of all imaginable value systems or the set of space-time coordinates Minkowski called the world. This is now called the manifold. The manifold is four-dimensional and each of its space-time points represents an event."

"Minkowski, building on Einstein's work, had now discovered that the Universe is made of a four-dimensional "spacetime" fabric that is absolute, not relative."

"Minkowski's idea and the solution of the twin paradox can best be explained by means of an analogy between space and spacetime... Time as a fourth dimension rests vertically on the other three—just as in space the vertical juts out of the two-dimensional plane as a third dimension. Distances through spacetime comprise four dimensions, just as space has three. The more you go in one direction, the less is left for the others. When a rigid body is at rest and does not move in any of the three dimensions, all of its motion takes place on the time axis. It simply grows older. ...The faster he moves away from his frame of reference... and covers more distance in the three dimensions of space, the less of his motion through spacetime as a whole is left over for the dimension of time. ...Whatever goes into space is deducted from time. ...In comparison with the distances light travels, all distances in the dimensions of space, even those involving airplane travel, are so very small that we essentially move only along the time axis, and we age continually. Only if we are able to move away from our frame of reference very quickly, like the traveling twin... would the elapsed time shrink to near zero, as it approached the speed of light. Light itself... covers its entire distance through spacetime only in the three dimensions of space... Nothing remains for the additional dimension... the dimension of time... Because light particles do not move in time, but with time, it can be said that they do not age. For them "now" means the same thing as "forever." They always "live" in the moment. Since for all practical purposes we do not move in the dimensions of space, but are at rest in space, we move only along the time axis. This is precisely the reason we feel the passage of time. Time virtually attaches to us."

"When he enrolled as a student in the Polytechnic, Einstein developed a know-it-all attitude, and he paid little attention to Minkowski's lectures and skipped many. Minkowski described him as a "lazy dog," and years later, upon the publication of the theory of relativity, he commented, "I really would not have believed him capable of it.""

"The geometrical theory of numbers... first gained prominence when Hermann Minkowski (1793-1909), who served as professor of mathematics at several universities, published his Geometrie der Zahlen (1896)."

"Ever since Hermann Minkowski's now infamous comments in 1908 concerning the proper way to view space-time, the debate has raged as to whether or not the universe should be viewed as a four-dimensional, unified whole wherein the past, present, and future are regarded as equally real or whether the views espoused by the possibilists, historicists, and presentests regarding the unreality of the future (and, for presentests, the past) are more accurate. Now, a century after Minkowski's proposed block universe first sparked debate, we present a new, more conclusive argument in favor of eternalism."

"The discovery of Minkowski... is to be found... in the fact of his recognition that the four-dimensional space-time continuum of the theory of relativity, in its most essential formal properties, shows a pronounced relationship to the three-dimensional continuum of Euclidean geometrical space. In order to give due prominence to this relationship, however, we must replace the usual time co-ordinate t by an imaginary magnitude, \sqrt -1\cdot ct, proportional to it. Under these conditions, the natural laws satisfying the demands of the (special) theory of relativity assume mathematical forms, in which the time co-ordinate plays exactly the same role as the three space-coordinates. Formally, these four co-ordinates correspond exactly to the three space co-ordinates in Euclidean geometry. ...These inadequate remarks can give the reader only a vague notion of the important idea contributed by Minkowski. Without it the general theory of relativity... would perhaps have got no farther than its long clothes."

"In a Newtonian view, space and time are separate and different. Symmetries of the laws of physics are combinations of rigid motions of space and an independent shift in time. But... these transformations do not leave Maxwell's equations invariant. Pondering this, the mathematicians Henri Poincaré and Hermann Minkowski were led to a new view of the symmetries of space and time, on a purely mathematical level. If they had described these symmetries in physical terms, they would have beaten Einstein to relativity, but they avoided physical speculations. They did understand that symmetries in the laws of electromagnetism do not affect space and time independently but mix them up. The mathematical scheme describing these intertwined changes is known as the Lorentz group, after the physicist, Hendrik Lorentz."

"By laying down the relativity postulate from the outset, sufficient means have been created for deducing henceforth the complete series of Laws of Mechanics from the principle of conservation of energy (and statements concerning the form of the energy) alone."

"It would be very unsatisfactory if the new way of looking at the time-concept, which permits a Lorentz transformation, were to be confined to a single part of Physics."

"The assumption of the contraction of the electron in Lorentz's theory must be introduced at an earlier stage than Lorentz has actually done."

"[Zurich,] where the students, even the most capable among them, ... are accustomed to get everything spoon-fed."

"H. A. Lorentz has found out the Relativity theorem and has created the Relativity postulate as a hypothesis that electrons and matter suffer contractions in consequence of their motion according to a certain law. A. Einstein has brought out the point very clearly, that this postulate is not an artificial hypothesis but is rather a new way of comprehending the time-concept, which is forced upon us by observation of natural phenomena."
