然而，杜胜望相信爱因斯坦是正确的，他决心测量单个光子的极限速度，通过这一前无古人的实验来结束这场争论。

Du, however, believed Einstein was right and determined to end the debate by measuring the ultimate speed of a single photon, which had not been done before.

为了方便测量，格罗斯教授和他的团队通过一个特殊的盒子——谐振器——来捕获光子。

To facilitate the measurements, Professor Gross and his team captured the photon in a special box, a resonator.

光子如何降落完全描述了粒子的位置，但是通过撞击，测量已经改变了粒子的向量。

How the photon lands completely describes the particle's position, but by hitting it, the measurement changes the particle's momentum.

Well, if I go through that, the wavelength of such a photon is going to be so big that I am back to measuring the dimension of the human hair with the yardstick.

好的，如果我做完了这个，那个一光子的的波长将成为,我将回头测量的,用一个尺度测量出人头发的尺寸。
