Extractions: [published in: Oriental Numismatic Society Newsletter 179 (Spring 2004), p. 5-9] After a centuries of mere curiosity on Oriental coins appearing in collections from the time of the renaissance, Islamic numismatics started as an offspring of theology in the eighteenth century. In 1724, the orientalist Georg Jacob Kehr (1692 - 1740) from Leipzig wrote the first monograph on Islamic numismatics which described a hoard of Islamic coins found near Gdansk. Richard Ettinghausen regarded this monograph as marking the beginning of Islamic archaeology (Ettinghausen, R.: Islamic Art and Archeology. In: T. Cuyler Young (ed.): Near Eastern Culture and Society , Princeton 1951, 17-47, esp. 21). By the end of the 18th century, in the period of the theology of the Enlightenment, a scientific discourse had come into being in Germany conducted by Protestant theologians who were both interested in historical matters and able to read Arabic. Their interest was often initially aroused by Islamic coins found in their native regions, usually around the Baltic Sea. These dated mainly from the tenth century, a period when the Vikings had established trade contacts with the core lands of the Islamic empire and then with Central Asia. The first specialised collections were also formed in the time of the theology of the Enlightenment. In 1794, the theologian and orientalist Oluf Gerhard Tychsen (1734 - 1815) of Rostock published his

Extractions: At the Homann Cartographic Bureau, Mayer drew up some 30 maps of Germany. These established exacting new standards for using geographical data in conjunction with astronomical details to determine latitudes and longitudes on Earth. To obtain some of the astronomical details, he observed lunar oscillations and eclipses using a telescope of his own design.

Among Mayer's observations is a series of meridian transit times of the Sun which were observed across a 5-wire fiducial grid in the focalplane of the telescope (at about 30-fold magnification) and were timed using a precision pendulum clock designed by Franz Kampe. Although these observations have been analyzed several times before (Mayer, 1762 [published 1767]; Wittmann, 1980; Toulmonde, 1995) they still merit revisiting with regard to possible long-term variations of the solar diameter. From a recent analysis, using improved reduction techniques and as many as possible of Mayer's observations, the author has obtained the following results (where R is the angular solar semidiameter at 1 au): 1. The absolute time of meridian passage (transit of disk centre) was measured with an accuracy of typically ± 0.7 or 11" (note that in case of the Sun this must be inferred from the transit time of opposite

Extractions: The direct occasion for the interesting earthquake theory by the German astronomer TOBIAS MAYER JACOBI was writing his treatise on earthquakes on occasion of the Lisbon earthquake, the earth shocks could be noticed. Both scientists reported the dizziness they felt during the earthquake. But the theoretical explanation of these phenomena was totally different. While TOBIAS MAYER tried to explain this dizziness by a change of gravity with the ground of the earth not moving at all, JACOBI attributed them to real movements of the ground that could be noticed in the houses in Hannover. In the first place this explanation was also used by TOBIAS MAYER, since he only had two explanations of this natural phenomenon with all its destructive consequences: "It either happens due to a real vibration of the ground or not" So far the simplest explanation was that parts of the surface of the earth are tossed to and fro out of their natural position. According to this position it would be easy to understand why buildings and other objects that lie on the moving ground are brought out of balance and collapse. But more precise quantitative observations show that the inclination of the ground would have to be so high for houses to collapse, that enormous elevations or subsidence that nobody observes would have to arise. Assuming that a piece of the earth of about one mile (about 1,5 km) inclines for about 5 degrees, which still would not suffice to bring buidlings out of balance, one end of this piece would have to sink for about 1000 feet in relation to the immovable ground, while the other end would have to raise by this distance.

Extractions: If you have read this far, you may feel impatience with the many complications involved with subtractive color mixing. Isn't there some way to make color mixing simple? Yes, there is. For the past 400 years, the drug of choice to combat those headachy symptoms of color complexity and substance uncertainty has been the "primary" color no! Many artists have developed a dogmatic attachment to the concept of "primary" colors and the whole framework of color wheel mixing that goes with it. This page examines the history of this idea, from ancient color theories to modern colorimetry, to demonstrate that "primary" colors are only useful fictions That is, so called "primary" colors are either imaginary sensations you cannot see can't see actual lights or paints that cannot mix all colors , which means they are just one paint choice among many. I once received an email from a "color theorist" who insisted that the subtractive (CMY) "primaries" were "the primary colors of the universe." This section is somewhat technical. You may find the historical trivia useful to stun your art colleagues at gallery cocktail parties.
