Frühe Fälle der "Verwendung" von Analogien in der altgriechischen Medizin

Analogy in ancient Greek medical texts may be either explicit or implicit. Greek physicians of the fifth and fourth centuries B.C. often used explicit analogy, e.g. when trying to explain unobservable processes within the body by comparing them to observable processes in common objects. Such explicit analogies served several purposes: illustration, exemplification, confirmation, or a combination thereof. - Other analogies are implicit, particularly those originating in metaphors, i. e. in language. While explicit analogies were intended to support only marginal details of medical doctrines, analogies implicit in metaphors occasionally became the nuclei of comprehensive and therapeutically important doctrines, particularly with reference to the crisis of a disease. - Explicit and implicit analogies occur already very early (Homer, eighth century B. C.) and with characteristics which make it possible to assess the specific function of analogy in Greek medical texts of the fifth and fourth centuries B.C.

Henkama, ?Daddy Heng“ – A Mediator between the Kangxi Emperor and Jesuit Missionaries during Chinese Rites Controversy in the 18th Century

The author's main concern is to turn the somewhat enigmatic person of Henkama (1645/1646–1708), known under many (also false) names, into a more tangible historical figure. For this purpose, all the available sources in European languages, Manchu, and Chinese are taken into account. Beginning with investigating the very name of this Manchu official who was responsible for the administration of the affairs of the Europeans, the author tries to obtain available and solid knowledge of Henkama's life and work, possibly year by year, which goes far beyond what is normally known about him, i.e., his role as main intermediary during the papal legation in Beijing (December 1705 – August 1706). However, this mediatory role cost him the trust of all around him, including the Kangxi Emperor, who was convinced that Henkama had been paid off by the papal legate and cardinal Charles-Thomas Maillard de Tournon (1668–1710). At the end of his life, being in ill health, he became a Catholic. Henkama died in 1708 in disfavor due to slander. In the rest of his article, the author depicts another four important contact persons between the Kangxi Emperor (state administration) and Jesuit missionaries, all of whom are to be considered as Henkama's co-workers or his successors. Among these four, there are two Chinese – Zhao Chang (1654–1729) and Wang Daohua (fl. 1706–1720) and two persons of Manchu origin – Bursai (fl. 1705–1706) and Zhang Changzhu/Carki (fl. 1707–1722).     

Robert Hooke und die frühe Geschichte der Federwaage

A large number of the so-called electronic balances, for example those using wire strain gauges, are based on the elastic deformation of solid materials, and on the electrical measurement of the resulting changes in length. Such instruments must therefore be grouped into the class of spring balances. The spring balance operates within the limits of proportionality according to the law discovered by and named after Robert Hooke. No precise information about the spring balance can be found so far in the literature about balances: it is assumed that it was invented before 1700, without knowledge of the name of the inventor. As the result of a literature research it is shown that Robert Hooke found experimentally in 1676 with „ut tensio sic vis”︁ not only the physical principles which led to the law of elasticity: he also drew practical conclusions from it, and in the treatise De potentia restitutiva, published 1678, he described the most important types of spring balances. Experiments carried out by him to demonstrate the reduction of gravity with increasing altitude by using such a balance led, however, to a negative result because of its lack of sensitivity. Further developments for more than 100 years were necessary, until the spring balance come into more general application.     

Zur Gestalt der Erde im Weltbild des frühen Buddhismus

Summary In the gths of the Miglopa-Jtaka and the Gijjha-Jtaka an old Indian narrative is handed down in two basically identical versions which, however, differ from each other, in that the first and older one ascribes a square shape to the earth while the second one conceives it in the form of a wheel. Searching for an explanation for the coexistence of these seemingly contradictory cosmographic pictures in a canonical collection of Buddhist texts, the author of this article discusses in general the archaic cosmological concept of the flat circular disk of the earth, compares relevant sources from vedic and brahmanic literature, and points to some non-Indian tales which are of special interest particularly in regard to the Jtaka versions.
