    我:拉格朗日点

    我就在这个点周围做布朗运动。
     
     
    一面是火热的充满理想光辉的太阳,另一面是大多数人的脚拼命踩来踩去的坚实的大地。
     
     
    我不是一个理想主义者,也不是一个完美主义者,从来都不是。所以我必然会摆脱太阳,坠向实际的地面。
     
     
    我不想摔得太疼,也不想无奈地看着这个过程的发生,所以我会一直面向我的太阳,即使我已经站在地上。
     
     
    如果我在途中碰到了向太阳奔去的你,朋友。我想我会和你握握手,然后用力地在你屁股上来那么一脚。
     
     
    这样你就能越过拉格朗日点吧。

    拉格朗日点

    一个小物体在两个大物体的引力作用下在空间中的一点,在该点处,小物体相对于两大物体基本保持静止。这些点的存在由法国数学家拉格朗日于1772年推导证明的。在每个由两大天体构成的系统中,按推论有5个拉格朗日点,但只有两个是稳定的,即小物体在该点处即使受外界引力的摄扰,仍然有保持在原来位置处的倾向。每个稳定点同两大物体所在的点构成一个等边三角形。
