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、他们从两个不同的参照系来观察它。

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，如果坐在那颗橄榄上，就是一个非惯性参照系… … 没事吧？

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

他谈到了柱状参考框架以及他是如何认为该框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，无论观察者的参考系如何，光速始是恒定的。

The only people who could notice time on the moving spaceship passing slower for Stella would be observers in an inertial, or non-accelerating, reference frame — like Terra back on Earth.

移动飞船上拉的时间变慢了，唯一能觉察到这一点的人是在惯性或非加速参考系中的观察者，譬如在地球上的特拉。

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

但拉改变方向返程时，她输入的参考系与开始时的参考系不同。

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

嘿，我没有超速——在我的惯性参考系中。

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

以地球的参考系而言，重力只是向下拉。

If both observers were in the same reference frame, the described motion of the balls would occur because the balls had the same mass and were thrown with the same force.

如果两个观察者处于同一参考框架，那么所描述的球的运动就发生， 因为这些球的质量相同， 且是以相同的力抛出的。

Because as one pendulum is swinging, it provides the attachment point for the pendulum hanging below it, and so that pendulum is in this moving reference frame as it's swinging.

- 因为一个钟摆摆动时，它为悬挂在其下方的钟摆提供了附着点，因此钟摆在摆动时处于这个移动的参考系中。

And then we realized, of course, every part of your skin has to have a reference frame relative to the things it touches.

于是我们意识到，然，皮肤的每一部分都必须有一个相对于它所接触物体的参考框架。

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

但是斯特拉改变她的返程方向时，她进入了一个与她开始时不同的参照系。

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

再者， 这不是一个惯性参考系，因此， 牛顿第一定律在这个参考系中不成立。

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

从相互运动的各个参照系来看，事件的同时性永远无法达成一致。

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“参照框架”、“参照框架” ， 就以为自己突然就好了。

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

不能真的像我们刚才那样为光子定义一个参考框架。

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

在这个参考系中，这个物块在没有净外力的情况下加速。

So it's basically the whole theory is built on the idea that these columns have reference frames, and we're learning these models, and these grid cells create these reference frames.

因此， 整个理论基本上是建立在这样的观念之上：这些柱状结构拥有参考框架，我们正在学习这些模型， 而网格细胞则构建了这些参考框架。

According to special relativity, laws remain unchanged within the reference frame, the moving train or any other set of objects moving together.

根据狭义相对论， 在参考系内，无论是移动的列车还是其他共同运动的物体集合中， 定律保持不变。

Time in that moving reference frame will seem to equal time in your reference frame, multiplied by gamma.

这个移动参考系中的时间似乎等于参考系中的时间乘以伽马。
