rational point

In algebraic geometry and arithmetic geometry, a *rational point* of an arithmetic scheme $S$ is a morphism $Spec(Q) \to S$ from the ring spectrum of the rational numbers.

If $S$ is the algebraic variety of solutions to some polynomial equations, then a rational point corresponds to a solution of these equations in the field of rational numbers
