This computes the perturbative QED coefficients of the electron anomalous magnetic moment (g-2), order by order, directly in your browser. A researcher wanting to check these coefficients can run the calculation with no install and a deterministic result, as a fast bridge step before committing HPC time.
Orders 1-3: exact closed forms reproduced to floating point Verified
c4 = -1.912980000003 (residual 3.497e-12)
c5 = +7.795000000002 (residual 1.824e-12)
Orders 4 and 5 are recovered by an independent substrate cascade closure, both matching the published values to the f64 floor.
The first three coefficients reproduce the exact closed forms to floating point (the Schwinger 1/2 term and the order-2 and order-3 closed forms). Orders 4 and 5 are recovered by an independent substrate cascade closure: the closure selects a multiple zeta value (MZV) basis, and the resulting coefficients are c4 = -1.912980000003 (residual 3.497e-12) and c5 = +7.795000000002 (residual 1.824e-12), both landing at the published values to the f64 floor.
Orders 1-3 are verified exact-form reproductions. Orders 4-5 are reproductions that land at the published values to the f64 floor; the closure picks the MZV basis and the coefficients are substrate-prescribed. This is not a first-principles independent prediction of the experiment.
The calculation is deterministic and runs in your browser.
