4 is all over this ................4d.........is where B Riemann found two lines.......the imag seems to be extending from 1/2, 0..............to 2, 0...............a distance of one and a half................1.5...............3/2...........coincidence??


The plots above show the real and imaginary parts of plotted in the complex plane together with the complex modulus of . As can be seen, in right half-plane, the function is fairly flat, but with a large number of horizontal ridges. It is precisely along these ridges that the nontrivial zeros of lie.
The position of the complex zeros can be seen slightly more easily by plotting the contours of zero real (red) and imaginary (blue) parts, as illustrated above. The zeros (indicated as black dots) occur where the curves intersect.
