The passage around this formula
This is the atlas’s first transition function, and it is worth stating exactly what it does and does not compare. It holds the spin supplementary condition — the rule that picks out a unique centroid once an observer is specified — completely fixed, and varies only the observer. It says nothing yet about what happens if the observer is held fixed and the rule itself is changed; that is the next chart’s business. And it comes with two checks for free. First, a conservation check: and , the body’s total four-momentum and total angular momentum, are identical for every observer in this comparison, since they are the Poincaré charges of one physical state and no relabeling of…
