Counting Primes Functionally

After all this playing with the \zeta-function it is time to return to the overall objective of this whole exercise: counting prime numbers. The idea behind analytic number theory is that primes are unpredictable on the small scale, but actually surprising regular on the large scale. This is why we'll look at certain functions that behave pretty erratically when we look at every single value, but become smooth and "easy" to calculate once we "zoom out" and consider the global properties, the so-called asymptotic.
