Down on the plane, the circles bunch up around two points, minus one and one, and the longitudes become arcs swinging between them.", +"Shrink the ball to half its size, and slide it over by one half. The poles land on zero and one. And the equator, the circle halfway between the poles, now casts the straight line through one half.", +"That is zeta's grid. Lay the real thing on top and it fits, bent a little by the other primes. So the zeta picture is the ordinary stereographic picture: tipped a quarter turn, halved, and shifted by one half." +]
