What this part means
A raised number can be a power. When it is a label or bound, it selects a case or the upper limit of a sum; the formula’s structure distinguishes these uses.
Its job in the formula
A raised mark can be a power or an index. Its position and the surrounding notation determine which.

The passage around this formula
What none of these three charts ever disputes is and , the body’s total four-momentum and total angular momentum, the two Poincaré charges no relabeling of “centroid” touches. Every version of “where” argued about above is a statement about how is split into an orbital part and a spin part; the sum is never in question. That is the single invariant this entire atlas, sharp and operational charts alike, is built on top of: physics agrees completely on what the body has, mass, momentum, energy, and spin, and only argues about which point should be credited with carrying the orbital share of the angular momentum.

An exponent tells how a base is used in multiplication. In x³, x is the base and 3 is the exponent: x³ = x × x × x.
