The quadratic reciprocity law can be formulated in terms of the Hilbert symbol (a,b)v where a and b are any two nonzero rational numbers and v runs over all the non-trivial absolute values of the rationals (the archimedean one and the p-adic absolute values for primes p). ...

He formulated prime number theorem, which states that number of primes less than x is assimptotically ~x/logx. (error term is related to famous Riemann hypothesis which might have been recently proven); He published Disquisitiones Arithmeticae in 1801, which contained a his proof of quadratic reciprocity.

The Quadratic Reciprocity Theorem compares the quadratic character of two primes with respect to each other. The quadratic character of q with respect to p is expressed by the Legendre symbol , defined to be 1 if q is a quadratic residue (i.e., a square) modulo p, and -1 if not.
