0 · Steer the zeta path
The value of zeta along the critical line, drawn as a path in the plane. The slider is the height.
Try this. Push the height upward slowly and watch the path swing around and strike the centre. Every strike is a zero; the first comes at height 14.13, and they never stop.
Zeta is computed live in this page, by the same recipe as the repository's Python library, and the zero heights come from the same shipped table the tests re-verify.
