Guzheng a Chinese Zither The guzheng (a kind of Chinese zither) was the most popular instrument in China in ancient and medieval times. For this they design global and national control networks, using space and terrestrial techniques while relying on datums and coordinate systems.įrom the beginning, when the company was founded on Ap( Heinrich Wild, Workshop for Precision Mechanics and Optics) geodesy was the most improtand devision. Vintage small drawing pen instrument think this as come for a set very nice for anyones collection of instrument for dawing. Among the many traditional musical instruments of China, the most popular 10 instruments were the guzheng, erhu, dizi, pipa, guqin, hulusi, suona, xiao, Chinese drum, and bianzhong. Geodesists also study geodynamical phenomena such as crustal motion, tides, and polar motion. The design of the WILD Compasses affords quicker and more accurate settings because, as the opening of the compass. Geodesy, also named geodetics, a branch of applied mathematics and earth sciences, is the scientific discipline that deals with the measurement and representation of the Earth, including its gravitational field, in a three-dimensional time-varying space. The instruments always retain their beauty. These points are usually on the surface of the Earth, and they are often used to establish land maps and boundaries for ownership, locations (building corners, surface location of subsurface features) or other governmentally required or civil law purposes (property sales).

The handles are aluminum anodized, and can therefore resist tropical climates. They are finished to such a high degree of precision that very fine or heavy lines can be drawn at will without any scratching or cutting, with a perfectly even flow of the ink. The mathematics collections document the stories of several of these objects individually, including pens and pencils, dividers and compasses, squares and triangles, protractors, parallel rules, sectors.
The WILD drawing pens are hardened by a special process. Drawing instruments have been essential to mathematics, architecture, surveying, navigation, engineering design, and other technical endeavors from antiquity through the 20th century, although recently computer-aided drawing has largely superseded the use of instruments for drawing by hand. The design of the WILD Compasses affords quicker and more accurate settings because, as the opening of the compass is set, thanks to the careful adjustment of the leg articulation, there is no lateral play or backlash. The instruments always retain their beauty. Even perspiration and eraser particles, which so quickly turn any other metal drab, cannot discolor chromium steel.
Stainless steel is five times more resistant than Brass or German Silver. They are made out chromium containing stainless steel. The instruments are in very nice condition but the set is missing 3 pieces (top left 4th row down -2 pieces and the round "washer").From their website:"Wild Heerbrugg produced Precision Drawing Sets of Stainless Steel sets between 19.Wild Compasses are not merely chromium plated. The box has a locking mechanism in the lower right corner which works great.
