Hello everybody. My name is T.S. Spivet, I am ten years old and I am actually in sixth grade.Is there anyone in this room, who doesn't already at least have a PhD? So, I probablywon't be teaching you much tonight.Any one? But I like to tell you three things. First, thank you ... Thank you for not cancelling my award 'cause I was younger than you expected. Second, the wheel.As you can see they are powered by magnets.Yet as you know, they demagnetize within approximately four hundred years. On a human scale, it sounds like a lot. In geological time, it's not even a fraction of a second.On a human scale, it sounds like a lot. In geological time, it's not even a fraction of a second.So, we're actually far from having a perpetual motion. Any Questions? Yes, what is the third point?
大家好 我的名字是T.S.斯比维特 我十岁 正在读六年级 在座的各位有谁还没有博士学位么？ 有谁吗？ 今晚我可能并不能给各位传授些什么知识 但我想告诉各位三件事情 第一 谢谢你们 谢谢你们没有因为我的年纪而取消给我颁奖 第二，关于电磁轮 大家能看到里面有部分零件是磁铁 你们也一定知道四百年后磁铁将会消磁 对人类时间尺度而言，四百年似乎很长 但对地质年代而言，却只不过是沧海一粟 因此我们距离永动机还要走很长的路 有问题么？ 嗯，那么第三件事是什么？
