蒙德里安的作品看似简单，但眼球追踪研究证实它们是经过精心创作的，而且简单地旋转下一件作品，就会从根本上改变我们看待它的方式。
Mondrian's works are deceptively simple, but eye-tracking studies confirm that they are meticulously composed, and that simply rotating a piece radically changes the way we view it.
研究星团的天文学家已经注意到质量一定的行星(通过追踪表面阴暗冷却斑点来测量)，其旋转速度随着其星龄呈现可预测性的变化。
Astronomers who study star clusters have noticed that the speed at which a star of a given mass spins (measured by tracking cool, dark spots on the surface) also seems to vary predictably with age.
