The Nyquist theorem, in very simple terms, describes the minimum measurements you need to take to capture all the information in a signal. It turns out, if you have special information about what signal you expect to see, you can still figure it out using fewer measurements.

Generally speaking, it tells you how many measurements you need to take to capture the whole signal.

Or in terms of practical applications, it explains why CDs are "good enough" and audiophile stuff is very often bullshit.
