Here is a test done during spring break 2013 with importing graphs of functions to Google earth.
You see the function f(x,y) = 1/|zeta(x+i y)| which has the poles at the zeros of the zeta function. The graph is
placed in front of the Science Center. Click on a thumbnail to see 2000 x 1200 pictures.
The color at a point (x,y) is the argument of zeta(z) and the chosen
rectangle is -8≤ Re(z)≤ 8 and -90≤ Im(z) ≤ 90 or
in which there are 50 roots of the zeta function on the critical line Im(z)=1/2. A second shot took
the parameters -8≤ Re(z)≤ 8 and -150≤ Im(z) ≤ 150.
The video shows some flight simulator shots with a slalom around the roots of the zeta function. (Higher quality Quicktime or low resolution Webm,Ogg) Music "Fading like a flower" by Roxette 1991. |

And here is an other take with 106 nontrivial roots of the zeta function on the critical line re(z)=1/2.
The rectangle is [-8,8] x [-150.1,150.1] in the complex plane. It contains the following 106 zeros
(where each one appears plus or minus 1:
14.1347, 21.022, 25.0109, 30.4249, 32.9351, 37.5862, 40.9187,

Google Sketchup Test 2006After some attempts to use Google sketchup, I had in December 2006 a few free hours to try it out on a MacBook. I chose the Widner Library as a first object. Google 3DWare house. |
