Ancient China made unique contributions to many areas of science, including astronomy, calendric system, geography, mathematics, agriculture, medicine and the humanities. Records of solar and lunar eclipses are found in the inscriptions on bones or tortoise shells of the Shang Dynasty over 3,000 years ago. In the 2,100 years from the Qin Dynasty to the late Qing Dynasty (that is, from 221 B.C. to 1911), the 27 appearances of Halley's Comet were all recorded in China. Zhang Heng, of the Han Dynasty, invented a seismograph to determine the location of earthquakes, and the celestial globe that showed...
...such as compact fluorescent light bulbs, already exist, and other breakthroughs, like practical fuel cells that generate clean energy by combining hydrogen and oxygen, are being put to greater use all the time. The government has already begun to jump start the alternative-energy industry by purchasing products like solar cells in bulk...
...hard. Just moments before, the station's commander, Vasili Tsibliyev, had attempted to bring an unmanned cargo vessel in for a remote-control docking. When the ship was just a few yards from the station, it suddenly flew wide of the docking port, sideswiped one of the station's solar panels and slammed broadside into its Spektr science module. The collision punctured the Spektr's hull, releasing its atmosphere, and sent the entire station into a slow roll. For several days the lives of the crew members--as well as the future of the Russian space program--were in grave...
...Foale watched the screen, Lazutkin watched the window and Tsibliyev worked his sticks, Mir grew steadily larger on the TV. Tsibliyev picked up a stopwatch and began to click off blocks of time. Measuring the solar panels of the station as they grew larger against a grid overlying the screen and making some quick calculations with the watch, he could estimate how fast the spacecraft was closing. Judging by Tsibliyev's apparent calm, Foale reckoned things were going well...
...while the possibility of life somewhere else in the solar system seems exciting, the discovery is nothing new for Hibbittz...
