    Extractions: The leading German physicist of his day and an early advocate of the idea of panspermia . In a public lecture delivered in 1871 he said: Who can say whether the comets and meteors . . . may not scatter germs of life wherever a new world has reached the stage in which it is a suitable dwelling place for organic beings? We might, perhaps, consider such life to be allied to ours, at least in germ, however different the form it might assume in adapting to its new dwelling place. Criticizing this hypothesis, which was put forward independently in the same year by William Thomson (Lord Kelvin), Frederick Zöllner argued that meteorites reach such high temperature on falling through the Earth's atmosphere that any organisms contained within them would be incinerated. In reply, Helmholtz pointed out that the interior of a meteorite would remain cool during its passage through the air and, in any case, organisms on the surface might be thrown free before the temperature became intolerable.

Even German readers have often to rely on the microform version of Koenigsberger which is part of the Landmark of Science collection. A book reprint will be much more useful. And since there is no biographical account of Helmholtz up until today, Koenigsberger remains the most important source….’ – Dr. Henning Schmidgen, Max Planck Institute for the History of Science, Berlin Hermann Ludwig Ferdinand von Helmholtz (1821–94) had a huge influence on German science during the mid nineteenth century, bringing it to the forefront of world attention. He was a physicist and psychologist who made seminal contributions in both fields. His Treatise on Physiological Optics (reprinted last year by Thoemmes Press) transformed the study of vision by integrating its physical and psychological dimensions. Helmholtz explained the mechanism of ‘accommodation’, invented the ophthalmoscope, and revived the three-colour theory of vision first proposed in 1801 by Thomas Young. He also invented the telestereoscope, produced some novel visual illusions, and argued for the involvement of knowledge in perception. Helmholtz was an inspiration to many others – notably his student Heinrich Hertz, the discoverer of radio waves. Leo Koenigsberger’s three-volume

26. On The Conservation Of Force, By Hermann Von Helmholtz

    Extractions: 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.

    Extractions: Hermann von Helmholtz (1821 - 1894) Helmholtz was the eldest of four children and because of his delicate health was confined to home for his first seven years. His father taught him the classical languages, as well as French, English, and Italian. He also introduced him to the philosophy of Immanuel Kant and Johann Gottlieb Fichte and to the approach to nature that flowed from their philosophical insights. This "Nature philosophy," in the hands of early 19th-century investigators, became a speculative science in which it was felt that scientific conclusions could be deduced from philosophical ideas, rather than from empirical data gathered from observations of the natural world. ( photo courtesy Much of Helmholtz' later work was devoted to refuting this point of view. His empiricism, however, was always deeply influenced by the aesthetic sensitivity passed on to him by his father, and music and painting played a large part in his science. reference Other biographies: Ampère Arrhenius Avogadro Bacon ...

    Extractions: Print friendly Tell a friend Find subscription deals Hermann Helmholtz was one of the few scientists to master two disciplines: medicine and physics. He conducted breakthrough research on the nervous system, as well as the functions of the eye and ear. In physics, he is recognized (along with two other scientists) as the author of the concept of conservation of energy. Helmholtz was born into a poor but scholarly family; his father was an instructor of philosophy and literature at a gymnasium in his hometown of Potsdam, Germany. At home, his father taught him Latin, Greek, French, Italian, Hebrew, and Arabic, as well as the philosophical ideas of Immanuel Kant and J. G. Fichte (who was a friend of the family). With this background, Helmholtz entered school with a wide scope of knowledge. Though he expressed an interest in the sciences, his father could not afford to send him to a university; instead, he was persuaded to study medicine, an area that would provide him with government aid. In return, Helmholtz was expected to use his medical skills for the good of the government-particularly in army hospitals. Helmholtz entered the Friedrich Wilhelm Institute in Berlin in 1898, receiving his M.D. four years later. Upon graduation he was immediately assigned to military duty, practicing as a surgeon for the Prussian army. After several years of active duty he was discharged, free to pursue a career in academia. In 1848 he secured a position as lecturer at the Berlin Academy of Arts. Just a year later he was offered a professorship at the University of Konigsberg, teaching physiology. Over the next 22 years he moved to the universities at Bonn and Heidelberg, and it was during this time that he conducted his major works in the field of medicine.

    Extractions: Helmholtz, Hermann Ludwig Ferdinand von German physiologist, physicist, and inventor of the ophthalmoscope for examining the inside of the eye. He was the first to explain how the cochlea of the inner ear works, and the first to measure the speed of nerve impulses. In physics he formulated the law of conservation of energy, and worked in thermodynamics. Helmholtz's scientific work in many fields was intended to prove that living things possess no innate vital force, and that their life processes are driven by the same forces and obey the same principles as nonliving systems. He arrived at the principle of conservation of energy 1847, observing that the energy of life processes is derived entirely from oxidation of food, and that animal heat and muscle action are generated by chemical changes in the muscles.

Sciences et techniques Hermann von Helmholtz Biographie en résumé 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. Source: Thoemmes Press Portrait Gallery (reproduction autorisée) Vie et oeuvre Il a été de 1843 à 1848 médecin militaire à Potsdam, puis s'est voué à l'enseignement et a successivement occupé les chaires de physiologie des universités de Koenigsberg (1849), de Bonn (1855), de Heidelberg (1858) et celle de physique de l'université de Berlin (1871). L'Académie des sciences de cette dernière ville lui a ouvert ses portes dès 1857; la Société royale de Londres lui a décerné en 1873 la médaille Copley et l'Académie des sciences de Paris, qui l'avait élu correspondant en 1870, lui a attribué en 1892 la place d'associé étranger devenue vacante par le décès de dom Pedro. L'empereur d'Allemagne l'a anobli en 1885.

    Extractions: Paper $19.00tx 0-226-32659-4 Spring 1995 Hermann von Helmholtz was a leading figure of nineteenth-century European intellectual life, remarkable even among the many scientists of the period for the range and depth of his interests. A pioneer of physiology and physics, he was also deeply concerned with the implications of science for philosophy and culture. From the 1850s to the 1890s, Helmholtz delivered more than two dozen popular lectures, seeking to educate the public and to enlighten the leaders of European society and governments about the potential benefits of science and technology to a developing modern society. David Cahan has selected fifteen of these lectures, which reflect the wide range of topics of crucial importance to Helmholtz and his audiences. Among the subjects discussed are the origins of the planetary system, the relation of natural science to science in general, the aims and progress of the physical sciences, the problems of perception, and academic freedom in German universities. This collection also includes Helmholtz's fascinating lectures on the relation of optics to painting and the physiological causes of harmony in music, which provide insight into the relations between science and aesthetics.
