essay "the science of music: hermann von helmholtz and the psychophysics of perception" by brook stowe This essay on the work of 19th-Century German physician, physicist and philosopher Hermann von Helmholtz is the culmination of a compressed yet nevertheless wide-ranging exploration of the man and his work which began as a search for understanding of Helmholtzian thermodynamics and evolved instead into an analysis of the scientist's work in acoustical research, and his early forays into the psychophysics of human perception. The intent of this essay is two-fold: to both trace the trajectory of Helmholtz's life and the scientific pursuits which lead him into early psychophysical sensory research, and to demonstrate an at least basic, passing knowledge of the physical theorems and processes that formed the basis of his work. It should be noted that, while Helmholtz did psychophysical experimentation in both vision and sound, the analysis here will be confined to an examination of the latter for reasons of clarity and space. Comprising the basis of this examination are the four texts of this month's reading, anchored by the hernia-inducing

The Academy Education Fund The Ophthalmoscope and Hermann von Helmholtz Hermann von Helmholtz was born in 1821 in Pottsdam, Germany. He was one of the great scientific minds of the 19th century whose accomplishments were in both medicine and science. In 1850 Helmholtz prepared an experiment for his physiology students to demonstrate the law of conservation of energy. For the experiment Helmholtz constructed a crude instrument made of cardboard, glue and microscope glass plates. This device was the predecessor of the ophthalmoscope used today. Helmholtz had many great accomplishments other than the ophthalmoscope, including his mastery and definition of physiological optics, theory of heat and energy, theories of hearing and the phenomenon of color and accommodation. Helmholtz earned many significant awards for his work, including being awarded the addition of the suffix "von" to his name. This honor, which he received from Kaiser Wilhem I, is similar to that of being knighted and one that can be inherited by descendants. Special thanks for this exhibit go to Spencer E. Sherman, MD.

MORE INFO AND CHOICES Email: Description About the Editor DESCRIPTION (back to top) Hermann von Helmholtz (1821-1894) was a polymath of dazzling intellectual range and energy. Renowned for his co-discovery of the second law of thermodynamics and his invention of the ophthalmoscope, Helmholtz also made many other contributions to physiology, physical theory, philosophy of science and mathematics, and aesthetic thought. During the late nineteenth century, Helmholtz was revered as a scientist-sagemuch like Albert Einstein in this century. David Cahan has assembled an outstanding group of European and North American historians of science and philosophy for this intellectual biography of Helmholtz, the first ever to critically assess both his published and unpublished writings. It represents a significant contribution not only to Helmholtz scholarship but also to the history of nineteenth-century science and philosophy in general.

Publié pour la première fois en français. Sciences et techniques Hermann von Helmholtz Biographie en résumé Physiologiste et physicien allemand. L'une des figures marquantes de la science allemande du milieu du XIXe siècle, Hermann-Ludwig-Ferdinand von Helmholtz s'illustra principalement dans les domaines de la médecine et de la psychologie. Son Traité d'optique physiologique transforma la compréhension du phénomène de la vision grâce l'intégration de l'étude des dimensions physiques et psychologiques de celle-ci. Il mit de l'avant l'idée d'un rôle important de la connaissance dans la perception. Helmholtz fournit également une explication du mécanisme de l'"accommodation" de l'oeil, inventa l'ophthalmoscope et le téléstéréoscope et réactualisa la théorie des trois couleurs exposée par Thomas Young en 1801. Il fut une source d'inspiration pour bien des savants allemands, parmi lesquels Heinrich Hertz, le découvreur des ondes radio, qui fut son étudiant.

54. On The Conservation Of Force, By Hermann Von Helmholtz On the Conservation of Force, by hermann von helmholtz. http://my.execpc.com/~berrestr/hel-con.html

Home Etext > Helmholtz, On the Conservation of Force On the Conservation of Force by Hermann von Helmholtz Introduction to a series of lectures delivered at Carlsruhe in the Winter of 1862-1863 On this exact conformity with law depends also the certainty with which we know how to tame the impetuous force of steam, and to make it the obedient servant of our wants. On this conformity depends, moreover, the intellectual fascination which chains the physicist to his subjects. It is an interest of quite a different kind to that which mental and moral sciences afford. In the latter it is man in the various phases of his intellectual activity who chains us. Every great deed of which history tells us, every mighty passion which art can represent, every picture of manners, of civic arrangements, of the culture of peoples of distant lands or of remote times, seizes and interests us, even if there is no exact scientific connection among them. We continually find points of contact and comparison in our conceptions and feelings; we get to know the hidden capacities and desires of the mind, which in the ordinary peaceful course of civilised life remain unawakened. The last decades of scientific development have led us to the recognition of a new universal law of all natural phenomena, which, from its extraordinarily extended range, and from the connection which it constitutes between natural phenomena of all kinds, even of the remotest times and the most distant places, is especially fitted to give us an idea of what I have described as the character of the natural sciences, which I have chosen as the subject of this lecture.
