You will hear a university lecture on the early development of the telescope. First, you have some time to look at questions thirty-one to forty. 00:01:09,580 Now listen carefully and answer questions thirty-one to forty. 00:01:17,040 Good morning. Today's lecture is about the development of the telescope up until the end of the seventeenth century. We can trace the telescope's earliest form back to the twelve hundreds. History records Roger Bacon as possibly the first to invent a magnifying glass. The principal use of his invention was for reading. This proved to be a benefit mostly for researchers who, until then, had been forced to give up working while still relatively young because of impaired vision. In sixteen oh eight, a Dutch astronomer called Lieberhay discovered that if convex and concave lenses were put together, they created a magnifying glass through which things at a distance could be seen. He created a miniature telescope. It was so small that initially people took it to the theater for a better view of the stage. Galileo found out about Lieberhay's invention in the spring of sixteen oh nine and immediately set about improving it. Galileo experimented with different lenses, combining a weak convex lens with a strong concave lens. He discovered that this intensified the strength of the instrument. Unfortunately, the lenses the opticians were making for glasses were unsatisfactory for what Galileo wanted to do, as they did not have powerful enough magnification. Galileo therefore decided that to solve his problem, he would have to start the production of his own lenses. Eventually, he achieved a magnification about nine times more than you could see with the naked eye, an enormous improvement over everything else on the market. Galileo then decided to approach the Senate of Venice to demonstrate the improved instrument. Many senators were eager to try the new telescope and climbed the highest bell towers in Venice to look through the glass at ships far out to sea. The government of Venice were impressed by his invention's obvious potential and envisioned the advantages this eyeglass could have for the army. His first major astronomical discovery with the telescope was that the moon's surface was mountainous and not a perfect sphere as it had always been assumed. During the lunar cycle of twenty-eight days, he found that the shadows seemed to vary with the light. Galileo also figured out how to estimate the altitude of the mountains on the moon by looking for bright spots in the dark areas. Galileo looked for the spots when it was a half moon, and with geometry was able to calculate the elevation of the mountains. From these calculations, he was able to draw charts of the terrain and show the altitudes of the mountains. 00:04:19,959 In sixteen ten, Galileo's next major discovery was regarding Jupiter. Using a magnification telescope twenty times the strength of his previous ones, he looked at Jupiter on successive nights. His main observation was a trio of what initially seemed to be small stars close to Jupiter. However, by the fifteenth night, he realized that they were going around the planet in a daily orbit, and that in fact, they were moons, not stars. And three days later, he saw a fourth one. This discovery showed how important a telescope was for astronomers. They would now be able to see celestial objects that could not previously be seen by the naked eye. In the later sixteen hundreds, scientists started to make a stronger telescope, revealing the galaxy. Scientists realized that when they increased the length of the telescope, the intensity of magnification improved significantly. One such telescope was created in sixteen fifty-six and magnified over one hundred times. It had the incredible length of four meters. Telescopes continued to become longer over the next few years. And in fact, the astronomer, Hevarius, built one in sixteen seventy that was forty-three meters long. However, these telescopes were soon to prove useless for accurate observation because the slightest wind caused the instrument to shift. Finally, in sixteen seventy-five, astronomers abandoned the tube telescope and instead mounted the telescope on a building. Telescopes like this were called aerial telescopes. Scientists hoped that the stability of the mount would decrease the frustration when observing stars. Well, that's about it for today, and so I- 00:06:26,860 That is the end of section four. You now have half a minute to check your answers. ## 题目与答案 ### 31. Roger Bacon (1200s) His invention assisted 31_____ with sight problems when they were reading.
