We've learned through special relativity and general relativity that different clocks tick at different rates.

我们了狭义相对论和广义相对论，不同的时钟以不同的速率行走。

Another one was on the theory of special relativity.

是关于 狭义相对论。

Special relativity says that space and time are inextricably linked.

狭义相对论认为空间和时间是密不可分的。

They have courses on topics from applied computer science to special relativity.

他们开设了从应用计算机科到狭义相对论等主题的课程。

Actually, what occurred to Einstein was something more like the beginning of a solution to the problem of gravity, since it had been evident to him from the outset that one thing missing from the special theory was gravity.

实际上，爱因斯坦到的更像是开始为引力问题找答案。他从开头就清楚地认到，狭义相对论里缺少样东西，那就是引力。

As every schoolboy (and journalist with access to Wikipedia) knows, this flies in the face of special relativity, a theory devised by Albert Einstein precisely to explain the observation of Michelson and Morley.

每生（以及每查了维基百科的记者）都知道这结果与狭义相对论相悖。阿尔伯特？爱因斯坦发明了狭义相对论，准确解释了迈克耳孙和莫雷的观测结果。

If you'd rather not learn about special relativity then they have tons of other courses on topics like complex algebra, calculus, computational biology, and since you're watching this on a computer, computer science.

如果你不狭义相对论，他们有大量其他的课程，比如复杂代数、微积分、计算生物，以及既然你是在电脑上看的，那么还有计算机科。

The speed of light is a cornerstone in Einstein's theory of special relativity, which is what gives us the concept of causality: causes precede effects.

光速是爱因斯坦狭义相对论的基石，为我们提供了因果关系的概念：先因后果。

We know through the physics of Einstein's special theory of relativity that you can trade motion in space for motion in time.

根据爱因斯坦的狭义相对论，我们知道，可以把空间中的运动转换为时间中的运动。

But it's not really a paradox — just an example of how special relativity can be easily misunderstood.

但这并非真正的悖论，只是狭义相对论易被误解的例子。

It's not quite as simple as a globe globe because special relativity is a little weirder than roundness.

它不像地球仪那样简单，因为狭义相对论比球形更奇怪点点。

Bose sent his ideas to Albert Einstein, a German scientist famed for the special theory of relativity.

玻色把他的法寄给了阿尔伯特·爱因斯坦，位以狭义相对论闻名的德国科家。

But from having studied special relativity, the twins know it's not that simple.

但是通过研究狭义相对论，她俩知道事情没那么简单。

Special relativity is special for a few reasons.

狭义相对论之所以特殊有几原因。

Because special relativity says that if you warp space, you have to work time.

因为狭义相对论说，如果你要扭曲空间，那你也必须扭曲时间。

Like the explorers aboard the ABC Jungle Fruit are cruisers searching for resources beyond Earth in a class on Einstein's special relativity over at brilliant.org.

就像 ABC 丛林水果号上的探险者样，他们是在 brilliant.org 网站上关于爱因斯坦狭义相对论的课程中，寻找地球以外资源的巡航员们。

Special relativity is typically relegated to just a few days squeezed into the beginning or end of other physics courses.

狭义相对论通常被压缩成几天的课程，被放在了其他物理课程的开始或最后。

That's really the lesson of special relativity.

这就是狭义相对论的教训。

I think in part, this is because special relativity is not quite a big enough subject to ever get its own full class in physics departments.

我认为部分原因是，狭义相对论的内容并没有多到可以在物理系单开门课程。

Couple other things that are really special about special relativity are that it tells you if you're moving close to the speed of light, time dilates, it gets longer.

狭义相对论的其他特别之处在于，它告诉你，如果你以光速移动，时间会膨胀，它会变长。
