Why this formula appears here
An exact analytic evaluation, not a simulation, fixes the scale this actually requires. Take three clocks stacked vertically at heights -h , 0 , and +h near Earth’s surface, giving two edges y1 = ϕ(0)-ϕ(−h) and y2 = ϕ(h)-ϕ(0) . Their difference is an exact finite-difference identity up to a Taylor remainder of order h4 :
