A prediction of how many asteroids there areD. A pattern in the spacing of planets2.Why does the professor explain Bodes Law t

5、o the class?A. To describe the size of the asteroidsB. To explain how the asteroid belt was discoveredC. To explain how gravitational forces influence the planetsD. To describe the impact of telescopes on astronomy3.What does the professor imply about the asteroid belt?A. It is farther from the Sun

6、than UranusB. Bodes believed it was made up of small stars.C. It is located where people expected to find a planetD. Ceres is the only one of the asteroids that can be seen without a telescopeProfessorOK. Lets get going. Today Im going to talk about how the asteroid belt was discovered. And.Im going

7、 to start by writing some numbers on the board. Here they are: Well start with zero, then 3,.6,.12. Uh, tell me what Im doing.首段開門見山Female studentMultiplying by 2?ProfessorRight. Im doubling the numbers, so 2 times 12 is 24, and the next one Im going to write after 24 would be.Female student48.Profe

8、ssor48. Then 96. Well stop there for now. Uh, now Ill write another row of numbers under that. Tell me what Im doing. 4,7,10.How am I getting this second row?Male studentAdding 4 to the numbers in the first row.ProfessorIm adding 4 to each number in the first row to give you a second row. So the las

9、t two will be52,100, and now tell me what Im doing.Female studentPutting a decimal?ProfessorYes. I divided all those numbers by 10 by putting in a decimal point. Now Im going to write the names of the planets under the numbers. Mercury. Venus. Earth. Mars. So, what do the numbers mean? Do you rememb

10、er from the reading?Male studentIs it the distance of the planets from the Sun?ProfessorRight. In astronomical units-not perfect, but tantalizingly close. The value for Mars is off by.6 or 7 percent or so. Its.but its within 10 percent of the average distance to Mars from the Sun. But I kind of have

11、 to skip the one after Mars for now. Then Jupiters right there at 5-point something, and then Saturn is about 10 astronomical units from the Sun. Um,well, this pattern is known as Bodes Law. 定義處 Um, it isnt really a scientific law, not in the sense of predicting gravitation mathematically or somethi

12、ng, but its attempting a pattern in the spacing of the planets, and it was noticed by Bode hundreds of years ago. Well, you can imagine that these was some interest in why the 2.8 spot in the pattern was skipped, and um.but there wasnt anything obvious there, in the early telescopes. Then what happe

13、ned in the late 1700s? The discovery of.?轉(zhuǎn)折對比處Female studentAnother planet?ProfessorThe next planet out, Uranus-after Saturn.And look, Uranus fits in the next spot in the pattern pretty nicely, um, not perfectly, but close. And so then people got really excited about the validity of this thing and f

14、inding the missing object between Mars and Jupiter. And telescopes, remember, were getting better. So people went to work on finding objects that would be at that missing distance from the Sun, and then in 1801, the object Ceres was discovered.強(qiáng)調(diào)處And Ceres was in the right place-the missing spot. Uh

15、, but it was way too faint to be a planet. It looked like a little star. Uh, and because of its starlike appearance, um, it was called an asteroid. OK? Aster is Greek for star, as in astronomy. Um, and so, Ceres was the first and is the largest of what became many objects discovered at that same dis

16、tance. Not just one thing, but all the objects found at that distance from the asteroid belt. So the asteroid belt is the most famous success of his Bodes Law. Thats how the asteroid belt was discovered.轉(zhuǎn)折對比定義處總結(jié)性信息1.Whats Bodes Law?A. A law of gravitationB. An estimate of the distance between Mars
