Christian Manahl (Ames High), Distribution of primes in quadratic number fields
Midwest Undergraduate Math Symposium 2013, Indianola, IA

In extensions to the rational integers, such as Z[sqrt(2)] or Z[i], there are similarly prime numbers that are only divisible by themselves and one down to units. The question, in this case, is whether or not the primes in Z[sqrt(2)] are uniformly distributed.
