我的过去不能定义我。

The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.

即使在抽象中，数学也具有深远的现实应用。

我们感知世界的方式是由我们的期望塑造的，通常，我们看到的就是我们期望看到的。

Technology should serve the land, not dominate it.

我总是在寻找改进的方法。
