So they'll sample the planet two times per day, once in the daytime, and then once in the nighttime descending.
所以它们每天会对地球进行两次采样,一次在白天,然后一次在晚上下降的时候。

And then there's 43 times that I sampled a 1 in my sample population-- 43 times I sampled a 1, and the 1 is 1 minus 0.43 away from the mean because that is the mean, and I want to square that distance.
In signal processing, sampling is the reduction of a continuous signal to a discrete signal. A common example is the conversion of a sound wave (a continuous signal) to a sequence of samples (a discrete-time signal).
A sample is a value or set of values at a point in time and/or space.
