第2段
1 .<-MALE PROFESSOR:-> Let's take an everyday example-an ordinary round plat like you'd find in a kitchen.
我们从日常生活中举个例子吧，比如说一个普通的圆盘子，就是你能在厨房找到的那种。
2 .If you hold the plate directly in front of your face and look at it, what shape do you see?
如果你直接把这个盘子放在脸前面并看着它，那么你看到的是什么形状呢？
3 .A perfect circle, right?
一个完美的圆，对吗？
4 .Suppose you tilt the plate to a different angle, to a horizontal position, like you are planning to put food on it.
假设你把盘子倾斜至另一个角度，一个水平位置，就像你打算把食物放上去一样，
5 .Still a perfect circle?
这时你看到的还是一个完美的圆吗？
6 .No, the circle is now stretched out, flattened into an oval.
不是！这个圆现在已经展开变平，成了一个椭圆了。
7 .Do you conclude the plate has actually changed shape, or that it is a different object, not the same plate?
那么，你能说这个盘子实际上已经变形了吗？或者这是另外一个东西，不是同一个盘子了？
8 .Of course not, it looks different, but we perceive it as still being the same.
当然不能！它虽然看起来不一样，但是我们知道这还是同一个盘子。
9 .Here is a different example.
再举一个不同的例子。
10 .This classroom we are in, it is fairly large, right?
我们现在所在的教室很大，对吧？
11 .Now, from up close, from the front row, I appear to be relatively big, bigger than if you were in the last row, right?
对坐在前排的同学来说，我看起来比较大，比坐在最后一排的同学看见的我要大一些，是不是？
12 .But let's say you are sitting in a front row today, but tomorrow you are sitting in the back row.
我们假设今天你坐在前排，但是明天你坐在后排。
13 .From back there I am going to look smaller, but you don't think I've actually gotten smaller.
从后面的位置看起来我比较小，但是你不会觉得我真的变小了。
14 .You don't think you are seeing a different professor, a guy who looks like me except he is smaller.
你不会觉得你看见的是另一个教授，一个长得和我很像只是比我小一些的教授。
15 .No matter where you are, up close or for away, you understand without evening thinking about it that I am the same size, the same person.
无论坐在哪个位置，前面或者最后，你不用想都知道我的身材还是一样，我还是那个我。
