And the constant, if we redo it in modern SI units, 1 would take on the value of 1.1 1*10^7m-1 times 10 to the 7th reciprocal meters.

如果我们用现代国际单位制来改写它，这个值是1,1。

And we want to divide all of that by our wavelength, and to keep our units the same we'll do meters.

我们想用波长除以所有这些，而且保持单位统一我们采用米。

So, if we kind of think about the numbers we would need, we would actually need a velocity that approached something that's about 10 to the negative 30 meters per second.

所以如果我们稍微想想，我们需要的数值是多少，我们需要一个,大约为10的负30次方米每秒的速度。

So 1.1 times 10 to the -31 meters is not, in fact, a significant number when we're comparing it, for example, to the length of a ball, or the size of the baseball field.

所以1，1乘以10的负31次方米，事实上并不是一个很重要的数字，举例来说，当它与一个球的长度，或者一块棒球场地对比时。
