[ANT10] Prime decomposition in Z[√2]
We return to our study of primes. We don't yet have a general method to find the primes of anything other than Z[i], and eventually, we'll want to know that; so let's start for now with the (relatively easy) example of Z[√2]. How can we tell when a (rational) prime splits, remains inert or
