Numbers in astronomy[edit]

Astronomers use math all the time. One way it is used is when we look at objects in the sky with a telescope. The camera that is attached to the telescope basically records a series of numbers - those numbers might correspond to how much light different objects in the sky are emitting, what type of light, etc. In order to be able to understand the information that these numbers contain, we need to use math and statistics to interpret them.

Just FYI but to generate numbers, a detector must first convert light into electrons to be counted, unless it uses a photomultiplier first. But, units detected are counted to generate numbers. --Marshallsumter (discusscontribs) 20:41, 4 October 2016 (UTC)
