One quote adapted (in the words of Kalman) from Shannon

“信息论之父”香农有一段名言:


"This duality can be pursued further and is related to a duality between past and future and the notions of control and knowledge. Thus we may have knowledge of the past but cannot control it; we may control the future but have no knowledge of it."

不过后来流传的是其缩减版:


"We know the past but cannot control it. We control the future but cannot know it."


而这段话如果用“现代控制理论之父”卡尔曼的术语来陈述的话,则应该是:


"The past is Observable but not Controllable. The future is Controllable but not Observable."


此之谓,“过去可观不可控,未来可控不可观”?
