The passage around this formula

What zitterbewegung adds to the atlas is a fourth, sharper illustration of the same structural point as the Pryce trade-off: x^\hat{\mathbf x} and XNW\mathbf X_{\mathrm{NW}} disagree not by a fixed offset but by a time-dependent, oscillating quantity, largest exactly where a wavepacket carries significant negative-energy content, a regime the nonrelativistic limit removes entirely. As v ≪\ll c and the wavepacket is restricted to the positive-energy…
