- One thing that is true even in Newtonian ways of thinking about space and time or in Einsteinian ways of thinking about space and time is that these fundamental laws, as Laplace's demon shows us, work forward and backward in time. Knowing everything about the universe at one moment predicts the past as well as the future. That's because what we think of as the fundamental laws of physics do not have a directionality to time. They treat the past and future the same. But there's clearly a direction to time in the world. I remember what I was doing yesterday. I might guess what I'm going to do tomorrow, but I don't remember it in the same way. I have no photographs or memory books of the future. I was younger.
即使按照牛頓的時空思維方式或愛因斯坦的時空思維方式，有一點也是正確的，那就是這些基本定律，正如拉普拉斯定律向我們展示的那樣，在時間上向前和向後都起作用。在某一時刻了解宇宙的一切，就能預測過去和未來。這是因為我們所認為的基本物理定律並不具有時間方向性。它們對過去和未來一視同仁。但在這個世界上，時間顯然是有方向的。我記得我昨天在做什麼。我可能會猜測我明天要做什麼，但我不會以同樣的方式記住它。我沒有關於未來的照片或回憶錄。我年輕的時候

- We know the directionality, but what we don't, what we have to understand is that cardiac muscle really has to have a contraction just like skeletal muscle has to have a contraction for it to work.
我們知道方向性，但我們不知道的是，我們必須瞭解的是，心肌確實必須收縮，就像骨骼肌必須收縮才能工作一樣。

- And ions are nice in that we can control the ion energy and the directionality by using the geometry of the system and by having, by judicial use of RF power.
離子的好處在於，我們可以通過使用系統的幾何形狀和射頻功率來控制離子的能量和方向性。
- Ion energy and directionality are key to anisotropic etching.
離子能量和方向性是各向異性蝕刻的關鍵。

- And so they accelerate towards the surface, and they gain both energy and directionality.
於是，它們加速衝向地表，同時獲得能量和方向性。
- So lower pressure, less collisions, more directionality, more ion energy.
是以，壓力越低，碰撞越少，方向性越強，離子能量越大。

- Someone recently said a term I kind of like he said, the non stupid suspension of disbelief. And so what we have to do in the early days of our project, it's very hard to get at it. But I think it's like you need rigor and directionality to it or it's just random. But you need to have it be so that the play is guided to cause efficiency, not so much that it turns back into a grim grinding of the gears because you're not going to get radical innovation out of that.
最近有人說過一個詞，我有點喜歡他說的 "非愚蠢的懸念"。所以我們在項目初期要做的事，很難做到。但我認為，這就像你需要嚴謹性和方向性，否則就只是隨機的。但你需要有這樣的指導，以提高戲劇的效率，而不是讓它變成嚴峻的齒輪磨合，因為你不會從中獲得根本性的創新。

- Sometimes I can actually feel myself perceiving the speed and crisscrossing directionality of all the people in front of me.
有時，我真的能感覺到自己在感知前方所有人的速度和縱橫交錯的方向。
- But the retina is also sensing directionality.
但視網膜也能感知方向性。
