Ein Überblick. Am Anfang des Buches Ling Xian (灵 宪) über astronomische Theorien versuchte Zhang den Ursprung von Himmel und Erde sowie Fragen der Evolution zu klären. 想吸引更多的外国客户?

The first seismograph (dì dǒng yí 地动仪) of the world was invented by Zhang Heng (zhāng héng 张衡), a famous scientist in the Eastern Han Dynasty (dōng hàn 东汉, 25-220). Deutschland ist laut dem Berliner Virologen Christian Drosten zufolge nicht ausreichend auf die zukünftige Entwicklung der Pandemie vorbereitet. This they receive only when the Sun illuminates them. Doch diese sind eigentlich nicht verkaufsunwillig - nur der Preis, den die Stadt für die Ackerflächen anbietet, empört sie. Als chinesischer Leonardo da Vinci wird heute Zhang Heng, der Erfinder des ersten Seismographen, angesehen. Unter jedem Drachen steht ein Frosch, der mit offenem Maul nach oben in Richtung der Drachen schaut. [41] Zhang Heng's writing confirms the size of the imperial hunting park in the suburbs of Chang'an, as his estimate for the circumference of the park's encircling wall agrees with the historian Ban Gu's estimate of roughly 400 li (one li in Han times was equal to 415.8 m, or 1,364 ft, making the circumference of the park wall 166,320 m, or 545,600 ft). [43] Somewhat similar to the description of Sima Xiangru, Zhang described the Western Han emperors and their entourage enjoying boat outings, water plays, fishing, and displays of archery targeting birds and other animals with stringed arrows from the tops of tall towers along Chang'an's Kunming Lake. [100][107] While it was John Milne and Wang Zhenduo who argued early on that Zhang's "central pillar" was a suspended pendulum, Imamura was the first to propose an inverted model. Die Köpfe der acht Drachen stehen für die Himmelsrichtungen Osten, Westen, Norden, Süden, Nordosten, Nordwesten, Südosten und Südwesten. The excellence of his talent and the splendour of his art were one with those of the gods. When an earthquake occurred the dragon mechanism of the vessel was caused to vibrate so that a ball was vomited out of a dragon-mouth and caught by the toad underneath. Mehr als 1.200 Migranten warten auf der Insel Lampedusa darauf, wie es für sie weitergeht. The outflow clepsydra was a timekeeping device used in China as long ago as the Shang Dynasty (c. 1600–c.

Neinhauser, William H., Charles Hartman, Y.W. It was recorded in Sima Qian's Records of the Grand Historian of 91 BC that in 780 BC an earthquake had been powerful enough to divert the courses of three rivers.

Zhang meinte, dass sich die Sterne in der Nähe des Himmels langsamer und die weiter entfernt liegenden schneller bewegten.

Zhang Heng is the first person known to have applied hydraulic motive power (i.e. [97], To indicate the direction of a distant earthquake, Zhang's device dropped a bronze ball from one of eight tubed projections shaped as dragon heads; the ball fell into the mouth of a corresponding metal object shaped as a toad, each representing a direction like the points on a compass rose. [2][18] Zhang also mounted two statuettes of a Chinese immortal and a heavenly guard on the top of the inflow clepsydra, the two of which would guide the indicator rod with their left hand and point out the graduations with their right. [65] Zhang supported the "radiating influence" theory to explain solar and lunar eclipses, a theory which was opposed by Wang Chong (AD 27–97). Among the many impressive inventions of the Chinese scholar Zhang Heng (A.D. 78 - 139), there is an instrument for testing wind and earth movements. arrow) with their left hands, and indicate the graduations on it with their right hands, thus giving the time.[74]. He invented the world's first water-powered armillary sphere to assist astronomical observation;[1] improved the inflow water clock by adding another tank;[2] and invented the world's first seismoscope, which discerned the cardinal direction of an earthquake 500 km (310 mi) away. Also, the seismoscope is said to have detected a … Im antiken China vor 2000 Jahren war es nicht ungewöhnlich, dass ein Wissenschaftler zudem ein Maler und Dichter war.

Es war der erste Erdbeben-Detektor in der Geschichte der Menschheit und Zhang Heng gilt seitdem weltweit als Pionier der seismischen Forschung. Am 3.
