一个身材并不高大的老人站在一座喷泉前、仔细观察着落下的水幕,他神情专注,歪着头,从水幕的一边瞧到另一边,我走近些,看到他正摊开右手,以极快的速度在眼前上下摆动。 那是许多年前的事了。当时我还只是7年级学生,那天我们去普林斯顿大学参观,那个站在喷泉前的老人就是大名鼎鼎的阿尔伯特·爱因期坦。几分钟过去了,他仍在默默地舞动着他的手指。然后,突然转过身来问我:“你能做到吗?你能看到那些单个水珠吗?” 我模仿着他,也摊开手指在眼睛前面上下摆动, An elderly man who was not tall stood in front of a fountain and carefully observed the falling water curtain. He looked with concentration, leaned his head, and went from one side of the water curtain to the other. I approached and saw him spreading out. The right hand swings up and down in front of the eyes at an extremely fast speed. It was many years ago. At that time I was only a 7th grade student. We visited Princeton University that day. The old man standing in front of the fountain was the famous Albert Einstein. A few minutes later, he still silently danced his fingers. Then suddenly turned to me and asked, “Can you do that? Can you see those single drops of water?” I imitated him and spread my fingers up and down in front of my eyes.
