Today E=mc^2 is Einstein's most famous equation but another thoery he published the same year is more important and more controversial ,
今天E=mc^2是爱因斯坦最著名的方程式,但另一个他同年出版的理论更重要而且更有争议,
the special theory of relativity.
那就是特殊相对论。
When Einstein was a teenager he enjoyed imagining what it would be like to ride a beam of light.
当爱因斯坦还是一名青年的时候，他喜欢想象，就像驾驭着一束光一样。
Now he returns to this daydream and changes his life.
现在他返回到这个白日梦而那改变了他的生活。
In the spring of 1905 Einstein was writing on a bus and he looked back at the famous clock tower that dominates Bern Switzerland .
在1905年春天爱因斯坦在一辆公共汽车上写作时他回头看到著名的钟塔占瑞士伯尔尼的主导地位。
And he imagine what happens if that bus racing at the speed of light.
而他想象如果那辆公共汽车以光的速度行驶会发生什么。
In his imagination Einstein looks back at the clock tower and what he sees is astonishing.
在他的想象里爱因斯坦回头看着钟楼而且他所看到的令人震惊。
As he reaches the speed of light the ends of the clock appear frozen in time .
他达到了光速,时钟的两端开始将时间凝固住。
Einstein later writes the storm broken in my mind.
爱因斯坦后来写道暴风雨在我心中激荡。
All of sudden all of sudden everything everything can gush in forward.
突然间所有的一切一切滔滔不绝突然向前。
Einstein knows that back to the clock tower time is passing normally.
爱因斯坦知道回到钟楼的时间是正常通过。
But on Einstein's light speed bus as he reaches the speed of light,
但对于爱因斯坦而言，光速公交车使他达到光速,
the light from the clock can no longe catch up to him .
从时钟而来的光已经无法赶上他。
The faster he races through the space the slower he moves through time.
他穿越空间的越快,他通过的时间就越慢。
This special insights sparks the birth of Einstein special theory of relativity which says that space and time are deeply connected.
这种特殊的见解点亮了爱因斯坦的相对论说法,时间和空间都是紧密联系的。
In fact they are one in the same,
实际上它们是相同的,
a flexible fabric called space time.
一个被称为空间时间的柔性织物。
