Little Masterpieces of Science: Invention and Discovery But Helmholtz, and Thomson, are household words, and you well know that in them and their disciples the race of Pioneers maintains its ancient glory. Pioneers of Science The hypothesis of Laplace fits in remarkably well with the theory put forward in later times by Helmholtz, that the heat of the sun is kept up by the continual contraction of its mass. Astronomy of To-day A Popular Introduction in Non-Technical Language This difficulty Helmholtz gets over by suggesting that in such an ear two adjacent fibres are affected, but one more than the other.

The Will to Believe : and Other Essays in Popular Philosophy This is a scientific victory which dwarfs the work of Helmholtz, Avogadro, or Mendelejeff. The Crack of Doom The calculations of Helmholtz showed that a contraction of about 100 feet a year from the surface towards the centre would suffice for the purpose. Astronomy of To-day A Popular Introduction in Non-Technical Language Helmholtz has shown that in the act of seeing, various details remain unnoticed because they are immaterial in the concerns of life; and there are many other like instances.

Colleges in America Such is the teaching of the great principle of the Conservation of Energy as enunciated by Mayer and Helmholtz. Aether and Gravitation In the autumn of 1872 Helmholtz told me that his fever was quite cured, and that in the meantime two other patients had, by his advice, tried this method, and with the same success. Fragments of science, V. 1-2 He seems to have initiated the theory of color blindness that was later developed by Helmholtz. A Budget of Paradoxes, Volume I Helmholtz tells me all that he knows about the physics and physiology of the process, both beyond and within my brain. Mind and Motion and Monism And Helmholtz says: "Darwin's theory shows how conformity to the end in the formation of organisms can also originate without any intermingling of an intelligence by the blind administration of a law of nature." The Theories of Darwin and Their Relation to Philosophy, Religion, and Morality A remarkable feature about this hypothesis lies in the fact, that it is the very hypothesis that Von Helmholtz suggested as the explanation of the term. Aether and Gravitation The physical character of the agent which produces putrefaction was further revealed by Helmholtz in 1843. Fragments of science, V. 1-2 But it was not true because it came to Helmholtz in this way, but because it was subsequently verified and proved. Philosophy and Religion Six Lectures Delivered at Cambridge Until the publication of Helmholtz's work vocal theorists had known practically nothing of acoustics. The Psychology of Singing A Rational Method of Voice Culture Based on a Scientific Analysis of All Systems, Ancient and Modern Professors who, like Virchow, Helmholtz, and Mommsen, have a world-wide reputation, draw many to their classes; but there are other equally learned specialists with a more circumscribed reputation and influence. In and Around Berlin In view of the theory of the Aether presented in this work, however, both Clerk Maxwell's and Von Helmholtz's statements find their literal and perfect fulfilment. Aether and Gravitation These words of Helmholtz are, in my opinion, wiser and more applicable to the condition of Germany at the present moment than those which express the fears of Professor Virchow. Fragments of science, V. 1-2 Some great man of Science—I think, Helmholtz—said of a brilliant discovery of his, 'It was given to me.' Philosophy and Religion Six Lectures Delivered at Cambridge In this work Prof. Scripture overthrows several of the conclusions of Helmholtz which had hitherto furnished the basis of all the accepted theories of vocal acoustics. The Psychology of Singing A Rational Method of Voice Culture Based on a Scientific Analysis of All Systems, Ancient and Modern Confined in the house by typhoid fever, Helmholtz, with a little money which he had saved by great economy, bought a microscope which led him into the field of science where he became so famous. Architects of Fate or, Steps to Success and Power The properties of vortex motion were first mathematically calculated by Helmholtz, but it was left to Sir Wm. Aether and Gravitation A glance at the less technical writings of its leaders — of its Helmholtz, its Huxley, and its Du Bois-Reymond — would show what breadth of literary culture they command. Fragments of science, V. 1-2 Helmholtz was the first to demonstrate that the quality of all musical tones depends entirely upon the presence or absence of their upper partials. The Recent Revolution in Organ Building Being an Account of Modern Developments Helmholtz confined his experiments and demonstrations to the mouth-pharynx cavity, and investigated in particular the influence of this cavity in producing the various vowel and consonant sounds. The Psychology of Singing A Rational Method of Voice Culture Based on a Scientific Analysis of All Systems, Ancient and Modern The names of Virchow, Helmholtz, Häckel, out of a score of others, all of the first rank, are familiar to every person of education in the present and past generation. German Culture Past and Present A second position held by Helmholtz, Lord Kelvin, and others, suggests that minute living creatures may have come to the earth from elsewhere, in the cracks of a meteorite or among cosmic dust. The Outline of Science, Vol. 1 (of 4) A Plain Story Simply Told In this paper Helmholtz contends strongly against the view that the consciousness of space is inborn; and he evidently doubts the power of the chick to pick up grains of corn without preliminary lessons. Fragments of science, V. 1-2 "These tones," says Helmholtz, "are heard whenever two musical tones of different pitches are sounded together loudly and continuously." The Recent Revolution in Organ Building Being an Account of Modern Developments The laws of vowel and consonant formation formulated by Helmholtz are often cited in proof of the efficacy of exercises of this type. The Psychology of Singing A Rational Method of Voice Culture Based on a Scientific Analysis of All Systems, Ancient and Modern Madame Seiler and her master, the physicist Helmholtz, regarded the vocal mechanism very much in the same light as they did their laboratory apparatus. Voice Production in Singing and Speaking Based on Scientific Principles (Fourth Edition, Revised and Enlarged) The36 reckonings of Helmholtz and others, based upon the supposition that the solar energy is entirely derived from its gravitational contraction, must be superseded. Woman and Womanhood A Search for Principles But, as remarked by Helmholtz, we must be content to share our celestial pedigree with the meanest of living things. Fragments of science, V. 1-2 The fundamental fact that a genuinely logical activity of the brain goes on without language of any sort, in the adult man who has the faculty of speech, was discovered by Helmholtz. The Mind of the Child, Part II The Development of the Intellect, International Education Series Edited By William T. Harris, Volume IX. The researches of Helmholtz, Koenig, Willis, Wheatstone, Appunn, Bell, and others have shown that each vowel sound has its own characteristic pitch. Resonance in Singing and Speaking Several theories have been advanced with reference to its explanation, one of the most interesting being that proposed by Helmholtz. Physiology and Hygiene for Secondary Schools I proceeded to smash materialism, rationalism, and all the philosophy of Tyndall, Helmholtz, Darwin and the rest of the 1860 people into smithereens. Gilbert Keith Chesterton Helmholtz considers that one-tenth of a second is demanded for this purpose. Fragments of science, V. 1-2 Men could not reward Shakespeare, or Darwin, or Newton, or Helmholtz for their services any more than we could pay the Lord for the use of His sunshine. The Story of the Innumerable Company, and Other Sketches Helmholtz, on pitch of vowel sounds, 20; on acoustics, 43, 49. Resonance in Singing and Speaking The following, proposed by Helmholtz, is the theory most generally accepted: The lens is held in place back of the pupil by the suspensory ligament. Physiology and Hygiene for Secondary Schools When Helmholtz says that life had no beginning, he is in the same case. The Breath of Life Mayer first, and Helmholtz and Thomson afterwards, have calculated its amount. Fragments of science, V. 1-2 Helmholtz styled it the essential basis of music. For Every Music Lover A Series of Practical Essays on Music The idealists in poetry, music, and philosophy gave place to great men of science, to figures such as those of Ludwig and Liebig, of Gauss, Riemann, and Helmholtz. Before the War Not Helmholtz or Chevreul can tell me anything new in the science of optics. Visionaries And this exactly answers to Helmholtz's contention that elementary sensations as partial tones can be detected after practice. Illusions A Psychological Study Following the method pursued by Helmholtz, I will here attempt an elementary exposition of this law. Fragments of science, V. 1-2 He relies on Helmholtz's fundamental theory of sounds. Myth and Science An Essay Mommsen, Virchow, Curtius Helmholtz, stand side by side in defence of the rights of liberty of thought. The Schemes of the Kaiser In vain I assured him that Helmholtz has demonstrated that the deepest blue eye is after all only a turbid medium. Infelice For a fuller account of the various mechanical arrangements for producing optical illusion, I must refer the reader to the writings of Sir D. Brewster and Helmholtz. Illusions A Psychological Study I should be very glad if the above lines would induce medical men in England — the haunt of hay fever — to test the observation of Helmholtz. Fragments of science, V. 1-2 It seems to me that although Helmholtz's theory is true, that of Berg is erroneous, since he is quite unable to prove his assertion that the effect produced by music is a negative pleasure. Myth and Science An Essay I would rather have carved a wooden Mary like this"—indicating the statue by Riemenschneider—"than have been Robert Koch and Helmholtz rolled into one. Atlantis Ask the shade of the great Helmholtz why he did not patent the ophthalmoscope. Craftsmanship in Teaching The value of these means of producing illusion at the command of the painter, may be illustrated by the following fact, which I borrow from Helmholtz. Illusions A Psychological Study In my lecture on Dust and Disease in 1870, I referred to an experiment made by Helmholtz upon himself which strikingly connected hay fever with animalcular life. Fragments of science, V. 1-2 The classic experiments of Helmholtz show that each note may be regarded as a harmonic whole, owing to the complementary sounds which accompany it in its complete development. Myth and Science An Essay See also Helmholtz _On the Conservation of Force._ The Birth-Time of the World and Other Scientific Essays From Helmholtz's analysis of sounds one would get the idea that the so-called tempered scale of our pianos caused thirds and sixths to sound discordantly. Critical and Historical Essays Lectures delivered at Columbia University Helmholtz explains the phenomenon by saying that the feeling we call by the name of wetness is a compound sensation consisting of one of temperature and one of touch proper. Illusions A Psychological Study About a year ago I received from Professor Binz of Bonn a short, but important paper, embracing Helmholtz's account of his observation, to which Professor Binz has added some remarks of his own. Fragments of science, V. 1-2 In the study of the time relations of neural processes Helmholtz was the pioneer. Harvard Psychological Studies, Volume 1 Containing Sixteen Experimental Investigations from the Harvard Psychological Laboratory. Helmholtz offers the explanation that the vivid colours are the result of the brighter sunlight of the heights. The Birth-Time of the World and Other Scientific Essays We remember that Helmholtz, Hanslick, and their followers denied to music the power to suggest things in nature; but it was somewhat grudgingly admitted that music might express the emotions caused by them. Critical and Historical Essays Lectures delivered at Columbia University Helmholtz, in order to account for the heat of the contracting sun, must have the cloud relatively cold. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work In the following year, at Innsbruck, Helmholtz took up the same ground. Fragments of science, V. 1-2 It is, perhaps, the formula proposed by Helmholtz which best accounts for all these peculiarities. The New Physics and Its Evolution We know that Newton who completes Galileo, Maxwell who follows Laplace, Helmholtz who uses the results of Joule, can have no conflicting jealousies. The Unity of Civilization According to Helmholtz, the sun's heat was maintained by the contraction of his mass, at the rate of about 220 feet a year. Scientific American Supplement No. 819, September 12, 1891 Helmholtz says of rotation, "the existence of which must be assumed." Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work Helmholtz refers to the dominant position acquired by Germany in physiology and medicine, while other nations have kept abreast of her in the investigation of inorganic nature. Fragments of science, V. 1-2 Poincaré, and, after him, Helmholtz, have both proposed electromagnetic theories of dispersion. The New Physics and Its Evolution Helmholtz had just published his works on the perception of colours and sounds by means of waves. The French Impressionists (1860-1900) Dr. Mott first gave a very elaborate and still at the same time condensed statement of the current theory of sound as propounded by such men as Helmholtz, Tyndall, Lord Rayleigh, Mayer, Rood, Sir Wm. Scientific American Supplement, No. 470, January 3, 1885 Many electricians, unacquainted with Helmholtz's law, have been in the habit of accounting for this by saying that there is a lag in the iron of the electromagnet cores. Scientific American Supplement, No. 787, January 31, 1891 In close connection with these utterances of Helmholtz, I place another utterance not less noble, which I trust was understood and appreciated by those to whom it was addressed. Fragments of science, V. 1-2 Von Helmholtz long since showed that electricity exercises an influence on the condensation of the vapour of water, and Mr C.T.R. The New Physics and Its Evolution M. Charles Henry, an original and remarkable spirit, occupied himself in his turn with these delicate problems by applying them directly to aesthetics, which Helmholtz and Chevreul had not thought of doing. The French Impressionists (1860-1900) Helmholtz has revealed the cause of the green produced by a mixture of blue and yellow pigments. Six Lectures on Light Delivered In The United States In 1872-1873 But Germany has furnished great individual workers, such as Fechner, Helmholtz, and Wundt. Cobwebs of Thought Hence, when Helmholtz, in 1851, affirmed, as the result of experiment, nervous transmission to be a comparatively sluggish process, very few believed him. Fragments of science, V. 1-2 The efforts of Helmholtz, Clausius, and Lord Kelvin to introduce the principle of the conservation of energy into mechanics, were far from useless. The New Physics and Its Evolution His work is a magnificent verification of the optical discoveries made by Helmholtz and Chevreul. The French Impressionists (1860-1900) On our way, then, we remove the fallacy, first exposed by Wünsch, and afterwards independently by Helmholtz, that the mixture of blue and yellow lights produces green. Six Lectures on Light Delivered In The United States In 1872-1873 As Helmholtz has said, "Apprehension by the senses supplies directly or indirectly, the material of all human knowledge, or at least the stimulus necessary to develop every inborn faculty of the mind." A Series of Lessons in Raja Yoga The subject waits for some one to correlate its various physiological, psychological and physical aspects in the same way that Helmholtz did for sound. Studies in the Psychology of Sex, Volume 4 Sexual Selection In Man Another consequence of the laws of Faraday, to which, as early as 1881, Helmholtz drew attention, may be considered as the starting-point of certain new doctrines we shall come across later. The New Physics and Its Evolution I look eventually to see woman physicists as eminent as Helmholtz and Kelvin, woman painters as great as Raphael and Velasquez, woman musicians as able as Bach and Beethoven. A Librarian's Open Shelf It is quite true, as Helmholtz says, that Young was in advance of his age; but something is to be added which illustrates the responsibility of our public writers. Six Lectures on Light Delivered In The United States In 1872-1873 Claude Monet has been thus far the most successful practitioner of impressionism; this by reason of his extraordinary analytical power of vision and native genius rather than the researches of Helmholtz, Chevreul, and Rood. Promenades of an Impressionist Helmholtz goes so far as to state that the expression of sexual longing in music is identical with that of religious longing. Studies in the Psychology of Sex, Volume 4 Sexual Selection In Man Helmholtz endeavoured to construct a mechanics based on the idea of energy and its conservation, but he had to invoke a second law, the principle of least action. The New Physics and Its Evolution Helmholtz and a number of distinguished German physicists and physiologists have analysed the vowel sounds in the whispering voice and obtained very different results. The Brain and the Voice in Speech and Song London milk makes an approximation to the same colour, through the operation of the same cause: and Helmholtz has irreverently disclosed the fact that a blue eye is simply a turbid medium. Six Lectures on Light Delivered In The United States In 1872-1873 The sub-minor seventh, expressed by the ratio 4:7 though included among the dissonances, forms, according to Helmholtz, a more perfect consonance with the tonic than does the minor sixth. The Beautiful Necessity Seven Essays on Theosophy and Architecture It was the illustrious Helmholtz, then in his best years, with great achievements behind him and before. The Last Leaf Observations, during Seventy-Five Years, of Men and Events in America and Europe Helmholtz, in a justly celebrated theory, endeavoured to fit the principle of Carnot into the principle of least action; but the difficulties regarding the mechanical interpretation of the irreversibility of physical phenomena remain entire. The New Physics and Its Evolution I have already said that Helmholtz showed that each vowel sound has its particular overtones, and the quality or "timbre" of the voice depends upon the proportional strength of these overtones. The Brain and the Voice in Speech and Song The paper of Helmholtz on the mixture of colours, translated by myself, is published in the Philosophical Magazine for 1852. Six Lectures on Light Delivered In The United States In 1872-1873 Ellis was at that time president of the London Philological Society, and had translated Helmholtz's The Sensation of Tone into English. Masters of Space Morse, Thompson, Bell, Marconi, Carty Helmholtz, a well-born youth, began his career as a surgeon in the Prussian army, and his service there, no doubt, contributed to the manly carriage for which he was conspicuous. The Last Leaf Observations, during Seventy-Five Years, of Men and Events in America and Europe Helmholtz has shown that the reduction of the Sun's radius at the rate of 45 meters per year would generate as much heat within the Sun as is now radiated. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 Helmholtz was able by means of resonators to find out what were the overtones for each vowel sound when a particular note was sung. The Brain and the Voice in Speech and Song Siemens would quickly, in German, explain the point, but Helmholtz could not see it, although he understood English, which Siemens could speak. Edison, His Life and Inventions Helmholtz had performed this experiment simply to demonstrate the physical basis of sound, and seems to have had no idea of its possible use in telephony. Masters of Space Morse, Thompson, Bell, Marconi, Carty Helmholtz had a lecture-room and laboratory apart, in a structure modern and graceful, but modest in its appeal. The Last Leaf Observations, during Seventy-Five Years, of Men and Events in America and Europe This principle was in part reannounced by Laplace a half century later, and likewise investigated by Helmholtz in 1854, before Kant's work was recognized. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 So it happened that when Bell ran to Ellis as a young enthusiast and told his experiments, Ellis informed him that Helmholtz had done the same things several years before and done them more completely. The History of the Telephone Siemens was very fond of these stories and would laugh immensely at them, and could see the points and the humor, by his imagination; but Helmholtz could not see one of them. Edison, His Life and Inventions The classic work of Helmholtz on ``Sensations of Tone'' is a highly musical composition on physics and physiology. The Project Gutenberg Encyclopedia Volume 1 of 28 Each Helmholtz of the future will give rise to a thousand Edisons. The Call of the Twentieth Century An Address to Young Men The principle of the ophthalmoscope, that wonderful instrument for inspecting the interior of the eye, was expounded by Helmholtz in 1851. Outline of Universal History Now, Helmholtz had not been trying to invent a telephone, nor any sort of message-carrier. The History of the Telephone This did not altogether complete the European trip of 1889, for Edison wished to see Helmholtz. Edison, His Life and Inventions Kelvin and Helmholtz have shown that the E.M.F. of a voltaic cell oan be calculated from the energy developed by the chemical action. The Project Gutenberg Encyclopedia Volume 1 of 28 Note how these figures agree with the age of the earth according to the Helmholtz contraction theory. The Evolution of Man Scientifically Disproved In 50 Arguments Helmholtz has defined the minimum angle measurable with the naked eye as being one minute of arc. History of Astronomy Compare this king with Helmholtz, who towers an intellectual Colossus above the crowned mediocrity. Lectures of Col. R. G. Ingersoll, Volume I Including His Answers to the Clergy, His Oration at His Brother's Grave, Etc., Etc. A musical instrument operating one of Helmholtz's artificial larynxes. Edison, His Life and Inventions Helmholtz dates his start in science to an attack of illness. The Pleasures of Life The solar radiation can be accounted for on the hypothesis first proposed by Helmholtz, that the sun is shrinking slowly but continually. The Evolution of Man Scientifically Disproved In 50 Arguments The best word to denote what music can express is that used by Helmholtz—Gemüthstimmung—untranslatable into English, but for which we may use the term "emotional mood" as denoting something similar. Wagner's "Tristan und Isolde"; an essay on the Wagnerian drama Still later, Helmholtz created there a new physics. The History of Education; educational practice and progress considered as a phase of the development and spread of western civilization Now Mr. Upton was a very able mathematician, who, after he finished his studies at Princeton, went to Germany and got his final gloss under that great master, Helmholtz. Edison, His Life and Inventions Let me also quote Helmholtz, one of the profoundest exponents of modern science. The Pleasures of Life Helmholtz separated a putrefying or a fermenting liquid from one which was simply putrescible or fermentable by a membrane which allowed the fluids to pass through and become intermixed, but stopped the passage of solids. Discourses Biological and Geological Essays He had an interesting dinner there with some of the literary men and savants—Mommsen, Leppius, Helmholtz, Curtius, etc., most of them his colleagues, as he was a member of the Berlin Academy. My First Years as a Frenchwoman, 1876-1879 This hypothesis found many supporters, among others the distinguished German physicist, Helmholtz. The Evolution of Man — Volume 2 The intellectual race that has produced Kant, Goethe and Helmholtz, Bismarck, Moltke, Mommsen, and Richard Wagner in a century, swallows Homeric draughts of beer at breakfast, dinner and supper. Greifenstein That identity of partial tones is not a sufficient explanation of consonance—as Helmholtz thought it to be—is proved by the fact that simple tones, which have no partials, may still be consonant. The Principles of Aesthetics Helmholtz further showed that the particular series of overtones into which a tone can be resolved is responsible for the colour of that tone as a whole. Man or Matter These questions have already been treated in detail and with unsurpassable lucidity by Helmholtz and Poincaré, whereas I can only touch on them briefly here. Relativity : the Special and General Theory Prof. Helmholtz of Konigsberg, to whom we owe the most complete investigation on visible colour, has given the true explanation of this phenomenon. Five of Maxwell's Papers When, a moment after, he glanced at her, she seemed to be reading Helmholtz. In the Year of Jubilee That of Helmholtz has held the field so long that, although weighty objections have been raised to it, it must still be treated with respect. The Psychology of Beauty Mayer's spiritual kin are not to be found among the heat-theorists of his time, such as Helmholtz and others, but among thinkers of the stamp of Goethe, Howard and Ruskin. Man or Matter In connection with this statement, it is interesting to refer to the experiments of Helmholtz on the rapidity of transmission of the nervous actions. Medical Essays, 1842-1882 A theory, which Sir W. Thomson has founded on Helmholtz's splendid hydrodynamical theorems, seeks for the properties of molecules in the ring vortices of a uniform, frictionless, incompressible fluid. Five of Maxwell's Papers With respect to sounds, Helmholtz has explained to a certain extent on physiological principles, why harmonies and certain cadences are agreeable. The Descent of Man It has done so because, in the words of Helmholtz, it contained "an essentially new creative thought," that of the continuity of life, the absence of breaks. Darwin and Modern Science But Helmholtz readily demonstrated the contrary, showing that the nerve cord is a relatively sluggish message-bearer. A History of Science — Volume 4 In accordance with the theory of Helmholtz, the chief supply of solar energy is held to be contraction of the solar mass itself; and plainly this must have its limits. A History of Science — Volume 3 We are now brought to one of the profoundest speculations of modern times, the vortex-atom theory of Helmholtz and Thomson, in which the evolution of ordinary matter from ether is plainly indicated. The Unseen World and Other Essays Helmholtz has explained on physiological principles why concords are agreeable, and discords disagreeable to the human ear; but we are little concerned with these, as music in harmony is a late invention. The Descent of Man Interesting in another way were two men eminent in physical science—Helmholtz and Hoffmann. Autobiography of Andrew Dickson White — Volume 1 This phenomenon is well-known, as are Helmholtz's and Plateau's explanations of it. Criminal Psychology; a manual for judges, practitioners, and students The mathematical calculations were largely the work of Hermann von Helmholtz, who, about the year 1858, had undertaken to solve some unique problems in vortex motions. A History of Science — Volume 3 Apart from such questions it is every way probable that the primary assumption of Helmholtz and Thomson is only an approximation to the truth. The Unseen World and Other Essays We are more concerned with melody, and here again, according to Helmholtz, it is intelligible why the notes of our musical scale are used. The Descent of Man Helmholtz and Hoffmann; a Scotch experience of the latter. Autobiography of Andrew Dickson White — Volume 1 Helmholtz has made this most clear: ``Our visions and representations are effects; objects seen and represented have worked on our nervous system and on our consciousness. Criminal Psychology; a manual for judges, practitioners, and students Helmholtz found that a vortex whirl, once established in a frictionless medium, must go on, theoretically, unchanged forever. A History of Science — Volume 3 One of the commonest sounds is a deep Oh; and this would naturally follow, as explained by Helmholtz, from the mouth being moderately opened and the lips protruded. The Expression of the Emotions in Man and Animals Helmholtz, on pleasure derived from harmonies; on the human eye; on the vibration of the auditory hairs of crustacea; the physiology of harmony. The Descent of Man Helmholtz's recent discoveries in acoustics inspired him to make research in that direction. A Biography of Sidney Lanier Even if Helmholtz is right, it is important for the lawyer to recognize the distinction between the witness who has the gymnasium behind him and the educated man who has helped himself without that institution. Criminal Psychology; a manual for judges, practitioners, and students Only the frictionless medium was lacking to fulfil all the conditions of Helmholtz's indestructible vortices. A History of Science — Volume 3 Helmholtz has also fully discussed in this profound work the relation of the form of the cavity of the mouth to the production of vowel-sounds. The Expression of the Emotions in Man and Animals Helmholtz adds that weakly objective images disappear like a wet spot on warm tin, at the moment a single point is fixed, as does e. g., a landscape seen at night. Criminal Psychology; a manual for judges, practitioners, and students According to Helmholtz the power of the full moon is not more than that of a candle twelve feet away. Criminal Psychology; a manual for judges, practitioners, and students Helmholtz tells how, as child, he asked his mother to get him the little dolls from the gallery of a very high tower. Criminal Psychology; a manual for judges, practitioners, and students The names of these three Germans are Mohr, Mayer, and Helmholtz. A History of Science — Volume 3 According to Helmholtz, it is senseless to ask whether cinnabar is red as we see it or is only so as an optical illusion. Criminal Psychology; a manual for judges, practitioners, and students Helmholtz made 1850 measurements which proved that the nervous current moves 90 feet a second. Criminal Psychology; a manual for judges, practitioners, and students Helmholtz has not said that the university improves the situation only in a very small degree, but it may be understood from his words. Criminal Psychology; a manual for judges, practitioners, and students This has been studied by Helmholtz and others, and he has shown how difficult it is to keep a point within the field of vision for only ten or twenty minutes. Criminal Psychology; a manual for judges, practitioners, and students Helmholtz's first point would, for legal purposes, require very broad interpretation of the term, ``universally valid laws,'' extending it also to laws in the judicial sense of the word. Criminal Psychology; a manual for judges, practitioners, and students According to Helmholtz: ``The effect of the blind spot is very significant. Criminal Psychology; a manual for judges, practitioners, and students Helmholtz suggests looking at a man walking in the distance, through the large end of a telescope.
