自然界系统的当前状态显然是前一时刻的结果，如果我们设想一个智能体在某一瞬间理解了宇宙中所有实体的关系，它就能陈述这些实体在过去或未来的任何时间的各自位置、运动和一般效应。
The present state of the system of nature is evidently a consequence of what it was in the preceding moment, and if we conceive of an intelligence which at a given instant comprehends all the relations of the entities of this universe, it could state the respective positions, motions, and general effects of all these entities at any time in the past or future.
以往的事过去了便不再重提，现在的事做一件有一件的功劳，未来的事情省一件便省去许多麻烦。
There’s a choice that we have to make as people, as individuals. If you want to be great at something, there’s a choice you have to make. We all can be masters at our craft, but you have to make a choice. What I mean by that is, there are inherent sacrifices that come along with that. Family time, hanging out with friends, being a great friend, being a great son, nephew, whatever the case may be. There are sacrifices that come along with making that decision.
