That is my spot. In an ever-changing world it is a simple point of consistency. If my life were expressed as a function in a four-dimensional Cartesian coordinate system, that spot, at the moment I first sat on it, would be 0000.

那是我的专座。在这个不断变化的世界里，这是不变的一点。 假设我的生命用一个建立在四维直角坐标系里的方程来表示的话， 这个座位从我坐上那一刻开始就成为了(0,0,0,0)。
