Formula Corrections

Formula corrections record changes to equations, assumptions, normalization choices, signs, factors, and formula-card metadata. They are high-priority because readers use formulas for calculations.

No public formula correction entries have been recorded yet for the current draft build.

What Belongs Here

Record a formula correction when a change affects:

a sign,
a factor of $2$ , $\pi$ , $2\pi$ , $\hbar$ , $c$ , or volume,
a matrix entry,
a normalization convention,
a boundary condition,
a domain or assumption,
a dimensional factor,
a displayed formula in a formula-card page,
an equation used by a worked example or benchmark.

Minor prose around a formula belongs in site errata only if the formula itself was correct.

Correction Entry

Use this format:

Field	Meaning
ID	stable correction identifier
page	affected page
formula label or section	where the formula appears
issue type	sign, factor, unit, convention, domain, notation, or typo
old form	short description, not a long quote
corrected form	corrected statement or formula
source checked	canonical page, textbook, paper, or derivation
status	confirmed, fixed, superseded, or wontfix
date fixed	date

Formula Review Checklist

Before marking a formula correction fixed, check:

dimensions,
limiting cases,
sign conventions,
normalization conventions,
consistency with the canonical derivation,
internal links to formula and derivation pages,
KaTeX rendering,
references.

Common Formula Error Types

A missing $\hbar$ after moving between natural and SI units.
A Fourier transform sign copied from a different convention.
A scattering amplitude formula quoted with a mismatched normalization.
A density-matrix trace formula with transposed subsystem ordering.
A Pauli or spin matrix with an incorrect sign.
