Put another way, blowing up an affine variety, at a point say, introduces projective geometry into it as a picture of its infinitesimal structure. For a field of size , the affine plane consists of the set of points which are ordered pairs of elements in and a set of lines which are themselves a set of points. << << In affine geometry the point X makes an infinite jump; but in projective geometry its motion, through the single point at infinity, is continuous.
