The non-trivial zeros of ζ(s) — points where the Riemann zeta function vanishes on the critical line Re(s) = 1/2 — encode the deviation of the primes from their smooth expected distribution. Each zero is a frequency. Add them one by one and watch the prime jumps emerge.
x^ρ/ρ to the difference between ψ(x) and the smooth function x. Pair it with its conjugate ρ̄, and you get a real wave: 2·√x · cos(γ·ln x − φ) / |ρ|. So each zero is a frequency; γ is the frequency, log(x) is the time axis, the amplitude rolls off like √x/|ρ|. The Riemann Hypothesis — that all non-trivial zeros lie exactly on Re(s)=½ — is the statement that the prime deviation has no "louder" component: every prime ripple is √x-bounded, not x^θ-bounded for θ > ½.
