He talks about columnar reference frames and how he thinks that's one of the keys to understanding the brain.

他谈到了柱状架以及他是如何认为该架是理解大脑的关键之一。

Unlike other objects, the speed of light is always constant regardless of an observer's reference frame.

与其他物体不同，无论观察者的系如何，速始终是恒的。

But when Stella changed her direction for the return journey, she entered a different reference frame from the one she'd started in.

但当史黛拉改变方向返程时，她输入的系与开始时的系不同。

Excuse me. If you were riding on the olive, you'd be in a non - inertial reference frame and would...Are you okay?

抱歉，如果你在那颗橄榄上，你就是一个非惯性照系并会… … 你没事吧？

Hey, I wasn't speeding—in my inertial reference frame.

嘿，我没有超速——在我的惯性系中。

'Down' is an illusion of your reference frame.

“下”是你的系产生的幻觉。

To  earth's reference frame, gravity just pulls in.

以地球的系而言，重力只是向下拉。

And you can't really define a reference frame for photons as we just did.

你不能真的像我们刚才那样为义一个架。

In this reference frame this  block accelerates without a net, external force.

在这个系中，这个物块在没有净外力的情况下加速。

And where does reference frames fit in?

系又扮演什么角色呢？

So again, a reference frame, I mentioned earlier about the model of a house.

再次提到，架，我之前提到过关于房的模型。

Well, what  Einstein showed with special relativity is that they're both correct…  in their own  reference frames.

嗯，爱因斯坦通过狭义相对论证明，这两种说法在各自的系中都是正确的。

Do not just start regurgitating frame of reference, frame of reference, and assume that you're suddenly healed.

不要只是开始机械地重复“照架”、“照架” ， 就以为自己突然就好了。

The first says that the laws of physics are the same in all inertial reference frames.

第一个说物理律在所有惯性系中都是相同的。

We do this by using units and frames of reference, which are also called reference frames.

我们通过使用单位和系（也称为系）来做到这一点。

From different reference frames moving relative to one another, there can  never be agreement on the simultaneity of events.

从相互运动的各个照系来看，事件的同时性永远无法达成一致。

Well, we state the reference frame we're using.

好吧，我们声明我们正在使用的系。

This reference frame is not an inertial reference frame.

这个系不是惯性系。

You know, you can have two events that happen and two different people looking at it from two different what we call reference frames.

可以有两个事件发生两个不同的人身上、他们从两个不同的照系来观察它。

Again, this is not an inertial reference frame, therefore, Newton's First Law does not hold true in this reference frame.

再者， 这不是一个惯性系，因此， 牛顿第一律在这个系中不成立。
