Transcript
English
Professor: OK, before we continue, does anybody have a question? Oh, lots of questions, I see. OK, we’ll go one at a time. Yes?
Student: Thank you. You talked about Fibonacci numbers in the lecture. Sorry, I don’t understand. Can you explain?
Professor: Of course. What do you want to know?
Student: OK … I hope this isn’t a silly question, but what does Fibonacci actually mean?
Professor: No question is ever silly – it’s always good to ask. OK, it’s the name of a person. Fibonacci was a European mathematician in the Middle Ages.
Student: Ah, OK. Thanks. So, we know he was a person, but what are the Fibonacci numbers? I don’t get it.
Professor: The Fibonacci numbers are a sequence of numbers. They go 1, 1, 2, 3, 5, 8 and so on. Do you see the sequence? Do you see how it works?
Student: I’m not sure.
Professor: OK. This is how it works. The first number is 1, then 1 again, then 2. The third number is the first number plus the second number. The fourth number is the second number plus the third number: 1 plus 2 is 3. The fifth number is the third number, 2, plus the fourth number, 3. So the fifth number in a Fibonacci sequence is 5.
Student: Ah! I think I understand now. But what about their importance? You said these were very important.
Professor: Yes, let me explain. This sequence of numbers is important because we see it in many things. Fibonacci numbers are common in geometry, they are common in nature, for example in plants. We see the sequence everywhere.
Student: Could you give us some more examples?
Professor: OK … well, we don’t have time right now but I can bring more examples in for next class, OK?

Professor: OK, before we continue, does anybody have a question? Oh, lots of questions, I see. OK, we’ll go one at a time. Yes?
教授：好的，在我们继续之前，有人有问题吗？哦，我看看，有很多问题。好的，我们一次回答一个。是的？Student: Thank you. You talked about Fibonacci numbers in the lecture. Sorry, I don’t understand. Can you explain?
学生：谢谢。您在讲座中谈到了斐波那契数列。抱歉，我不明白。你可以解释吗？Professor: Of course. What do you want to know?
教授：当然。你想知道什么？Student: OK … I hope this isn’t a silly question, but what does Fibonacci actually mean?
学生：好的……我希望这不是一个愚蠢的问题，但是斐波那契实际上意味着什么？Professor: No question is ever silly – it’s always good to ask. OK, it’s the name of a person. Fibonacci was a European mathematician in the Middle Ages.
教授：没有任何问题是愚蠢的——提出总是好的。好吧，这是一个人的名字。斐波那契是中世纪欧洲数学家。Student: Ah, OK. Thanks. So, we know he was a person, but what are the Fibonacci numbers? I don’t get it.
学生：啊，好的。谢谢。所以，我们知道他是一个人，但是斐波那契数是多少？我不明白。Professor: The Fibonacci numbers are a sequence of numbers. They go 1, 1, 2, 3, 5, 8 and so on. Do you see the sequence? Do you see how it works?
教授：斐波那契数列是一个数字序列。他们走1、1、2、3、5、8等等。你看到顺序了吗？你明白它是如何运作的吗？Student: I’m not sure.
学生：我不确定。Professor: OK. This is how it works. The first number is 1, then 1 again, then 2. The third number is the first number plus the second number. The fourth number is the second number plus the third number: 1 plus 2 is 3. The fifth number is the third number, 2, plus the fourth number, 3. So the fifth number in a Fibonacci sequence is 5.
教授：好的。这就是它的工作原理。第一个数字是 1，然后又是 1，最后是 2。第三个数字是第一个数字加上第二个数字。第四个数字是第二个数字加上第三个数字：1 加 2 等于 3。第五个数字是第三个数字 2 加上第四个数字 3。因此斐波那契数列中的第五个数字是 5。Student: Ah! I think I understand now. But what about their importance? You said these were very important.
学生：啊！我想我现在明白了。但它们的重要性又如何呢？你说这些非常重要。Professor: Yes, let me explain. This sequence of numbers is important because we see it in many things. Fibonacci numbers are common in geometry, they are common in nature, for example in plants. We see the sequence everywhere.
教授：是的，让我解释一下。这个数字序列很重要，因为我们在很多事情中都能看到它。斐波那契数在几何学中很常见，在自然界中也很常见，例如在植物中。我们随处可见这种顺序。Student: Could you give us some more examples?
学生：您能给我们举一些更多的例子吗？Professor: OK … well, we don’t have time right now but I can bring more examples in for next class, OK?
教授：好吧……好吧，我们现在没有时间，但我可以在下节课上举更多例子，好吗？
