Let me warn you against a mistake that historians of science often make. They sometimes assume that people in the past use the same concepts we do. Here is a wonderful example that makes the use of history of mathematics some while ago. It concerns an ancient Mesopotamian tablet that has some calculations on it using square numbers. The calculations look an awful one like the calculations of the link of the sides of triangle. So that’s what many historians assume they were. But using square numbers to do this is a very sophisticated technique. If the Mesopotamians knew how to do it, as historians started thinking that they did. Well, they learn math with incredibly advanced. Well, it turns out the idea of Mesopotamians use square numbers to calculate the link of triangle’ s sides is probably wrong. Why? Because we discovered that Mesopotamians didn’t know how to measure angles, which is a crucial element in the whole process of triangle calculations. Apparently the Mesopotamians had a number of other uses for square numbers.
These other uses were important but they were not used with triangles. And so these tablets in all likelihood were practice sheets, if you like, for doing simpler math exercises with square numbers. In all likelihood, it was the ancient Greeks who first calculate the link of triangle’s sides using square numbers. And this was hundreds of years after the Mesopotamians.
Now listen to the following recording and answer questions 23 to 25.
23. According to the professor, what did some historians mistakenly assumed about the Mesopotamians?
24. What was on the Mesopotamian tablet mentioned in the talk?
25. What does the professor imply about the ancient Greeks?
选项
A、They did not use square numbers.
B、They used complex measuring instruments.
C、They recorded math exercises on tablets.
D、They calculated the link of triangle sides.
答案
D
解析
细节题。根据The calculations look an awful one like the calculations of the link of the sides of triangle.So that’s what many historians assume they were.可知,历史学家认为那些汁算是关于三角形边的关系的。因此,正确答案是D。
