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

可有两个事件发生两个不同人身上、他们从两个不同参照系来察它。

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，如果你坐在那颗橄榄上，你就是一个非惯性参照系并会… … 你没事吧？

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他是如何认为该框是理解大脑关键之一。

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

与其他物体不同，无论察者参考系如何，光速始是恒定。

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.

移动飞船上史黛拉时间变慢了，唯一能觉察到这一点人是在惯性或非加速参考系察者，譬如在地球上特拉。

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

但当史黛拉改变方向返程时，她输入参考系与开始时参考系不同。

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

嘿，我没有超速——在我惯性参考系。

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

地球参考系而言，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.

如果两个察者处于同一参考框，那么所描述球运动就会发生， 因为这些球质量相同， 并且是相同力抛出。

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.

- 因为当一个钟摆摆动时，它为悬挂在其下方钟摆提供了附着点，因此钟摆在摆动时处于这个移动参考系。

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，当然，你皮肤每一部分都必须有一个相对于它所接触物体参考框。

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

但是当斯特拉改变她返程方向时，她进入了一个与她开始时不同参照系。

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.

从相互运动各个参照系来看，事件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”、“参照框” ， 就为自己突然就好了。

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

你不能真像我们刚才那样为光子定义一个参考框。

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

在这个参考系，这个物块在没有净外力情况下加速。

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念之上：这些柱状结构拥有参考框，我们正在学习这些模型， 而网格细胞则构建了这些参考框。

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，无论是移动列车还是其他共同运动物体集合， 定律保持不变。

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

这个移动参考系时间似乎等于参考系时间乘伽马。
