In this paper the use of analogies in physics and in technology is analysed. First the important role philosophically deep rooted analogies played in romantic physics is discussed. The work of Schelling and Ritter is treated in particular. Second the mechanical analogue models in the kinetic theory of gases and in electrodynamics are examined, as well as the severe philosophical criticism which they received. A sketch of the theory of the electron gas is presented as an example for the success and the shortcomings of analogue models. Finally mechanical and electric analogue models in technology are considered; moreover biological analogies in engineering research, and the principle of similitude as applied to model experiments in shipbuilding are discussed. The analysis of the historical examples shows that in the 19th and 20th century the word “analogy” is no longer a vague notion. It represents a scientific method, which, however, inevitably leads to both an extension of the original theoretical models and to special theories of mapping.  相似文献

In Auseinandersetzung mit einigen neueren Beiträgen (Andreae, Görler) sucht der Verf. die Schwierigkeiten im Abschnitt über die Laokoongruppe aufzuzeigen und zu lösen. Er behandelt dabei u.a. den logischen Zusammenhang, den Sinn von nec plures pariter nuncupari possunt, die Beziehung von sicut in Laocoonte zum Ganzen und nicht zuletzt die Bedeutung der Apposition opus omnibus ... praeferendum. Das Ergebnis der Analyse bestätigt wichtige Elemente der traditionellen Deutung.  相似文献

In the late 19th century at the “Technische Hochschulen” the understanding of “Wissenschaft” and “Bildung” changed considerably. During the 19th century the “Polytechnische Schulen” and “Technische Hochschulen” adopted the neo-humanistic standards of “Bildung”, established by the universities and the “Humanistische Gymnasium”. At the end of the century they joined the “realistische Schulbewegung” which emphasized the value of mathematics and natural sciences, taking issue with the classical languages. At the same time, systematic experimentation was added to mathematics, natural sciences and technical experience to constitute the specific methodology of engineering sciences. Attempts to define specific technical elements of “Allgemein-bildung” did not succeed as a result of the rapidly increasing differentiation and specialization of engineering sciences.  相似文献

As far as the law of preservation of matter and the existence of ether are concerned, Kant, Lomonossow and Lavoisier had very similar views. Nevertheless, according to historical evidence they worked out their theories never taking each other's results for granted. Whereas it is well known that Lavoisier did not base his experiments on the former ones by Lomonossow, it has been argued that Kant based his philosophy of nature on Lavoisier's experiments. I try to show here, that Kant had his philosophy of nature done, prior to Lavoisier's Elements of Chemistry. Further that the only one to have been able to influence Kant was not Lavoisier but Lomonossow. But Kant never mentioned Lomonossow. There is strong evidence that the similarity of views in Kant, Lomonossow and Lavoisier is not due to any kind of interaction between them. This also holds of the (same) mistakes, which Kant and Lomonossow made. The only substantial difference is that Kant thought, that some laws of nature may be logically inferred without experiments.  相似文献

The scientific interrelationships between Italy and Germany in the 18th and 19th centuries — a hitherto neglected area of research — are discussed in an overview according to the following ten dimensions: language knowledge and translations; reviews and bibliographies; library content; personal contents and correspondance; travel reports and travel guides; diaries and autobiographies; university studies and research sojourns; membership in academies and scientific societies; practical and theoretical resonance; comparisons to other countries. This approach, which has to be concretized in future studies, promises at the same time general insights into the logic of science and its progress.  相似文献

Since the late 17th century, two physical concepts of space exist. Isaac Newton's theory of an immovable ‘absolute space’ made it possible to explain motion and force by the quality of material elements. Less influential was Gottfried Wilhelm Leibniz's concept of space as an ‘order of coexistence’, which focuses, contrary to Newton, on the relationship between material bodies. The author argues that both concepts not only concern physical notions, but also include general models to explain cause, effect and relation. In an analogy to Newton's ‘absolute space’, theories of natural law employ the state of nature to explain society according to the anthropological quality of human beings. Leibniz's concept, in contrast, is used to elaborate theories of complex dynamic interactions and relationships. This essay attempts to illustrate the application of Leibniz's concept with examples of 18th century natural history, demography, economic theory and Charles Bonnet's natural law.  相似文献

The historical shift in the function of the hospital from an asylum for the care of the indigent sick to a medical‐therapeutic institution is intimately associated with the exploitation of the hospital as a clinical facility. Thus, over the course of the 19th century the space of the hospital and its disciplinary structure was permeated and reorganized by clinical practices. Drawing on the example of the Charite hospital in Berlin, it can be shown how the historical shift in the hospital's outward social function went hand in hand with the creation of a differentiated internal clinical space. In this compartmentalized clinical space the discipline of the hospital was replaced with methods of clinical examination, techniques of observation, and procedures of documentation, all of which helped to transform the hospital into a knowledge‐space.  相似文献
