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: and 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 c and the wavepacket is restricted…
