主题:美国求学执教的见闻和感受(0) -- changshou
参照系=a physics system. in classic physics, "up to" SR, we are all basically talking about 惯性参照系vs 惯性参照系 運動/movements, where in general we don't really have 加速度 in between 惯性参照系 per concept of 惯性参照系; in SR, we have 洛伦兹变换 to handle 運動 between 惯性参照系; linear;
GR: it is about 非惯性参照系 vs 非惯性参照系運動, non-linear, and as such conventional physics not working anymore in 引力场 , 引力场量子化(kind of 动力学运动学物理机制) is still a day dream to be realized by human civilization, 引力场幾何化 is a great concept & a great app in terms of 大尺度;
