Since the new beam was less intense than the original one, that came at the expense of the number of recorded events—just 20, compared with a whopping 16, 000 in the earlier analysis.

由于新中微子束的强度弱于原来的粒子束，因而记录到的事件数由原来实验中高达1万6千次减低到只有20次。

Because the beam was powerful enough to drill holes in razor blades, physicists measured its power in gillettes, or the number of blades penetrated.

由于激光光束的能量强大到足以在刀片上钻洞，物理学家使用穿透刀片的数量作为激光能量的计量单位。

So this gives you a little bit of an idea of just how many individual photons there are in a laser beam of light. This is a huge number of photons.

这个给你们一点思路关于,一个激光束有多少独立的光子,这是一个巨大的光子数目。

His thesis was based on algorithms that describe how a large number of independent devices could beam data to one another, an approach called mesh networking.
