Measured scores
Axes not listed were not scored for this book — coverage is uneven by design. All axes run 1–5, where 1 is the secular/pluralist/open pole. See the method.
Evidence recorded 3
Three kinds, deliberately styled apart. A quotation is verbatim wording and is only ever taken from English-medium text. An observation describes structure or theme — the only kind permitted for Urdu and Sindhi material, which this project never quotes. An absence is a negative result: a probe was run and returned nothing, which is the weakest claim made anywhere on this site.
observation religion lens A1 = 1 English OCR #e01
quotation history lens A3 = 3 English OCR #e02
absence gender lens A7 = 4 English OCR #e03
A negative result. It records that a probe was run and found nothing — not that the thing is not in the book. Where this rests on Urdu material the correct reading is not established, never absent, because degraded Nastaliq OCR cannot tell those apart.
Every passage recorded for this book is shown above — nothing is withheld or truncated. Each item has a permanent anchor, so a single piece of evidence can be linked and disputed on its own.
Findings that cite this book 2
Genderhigh confidence
Across eleven matriculation science volumes and roughly 530,000 words, a woman scientist is named four times, in three books, by two of the four boards. KP's Physics 10 names Marie Curie with her dates and credits Lise Meitner with the theoretical explanation of nuclear fission, printing her portrait. KP's Chemistry 9 names Madam Curie. Punjab's Physics 10 names Marie Curie once. Sindh and Balochistan name no woman scientist in any science volume, and none of the four boards names one below class 9.
Counter-evidence, at equal prominence: KP is simultaneously the worst board in the corpus on aggregate gender conservatism (A7 4.44). The board that scores worst on women's presence and agency is the only one that credits a woman with a major discovery in her own right. Aggregate ratios cannot see this; the per-book tables can.
Inquiryhigh confidence
Balochistan carries the highest evaluation-verb density in the corpus — History 8 alone sets 32 — and almost no open-opinion demand. The verbs are attached to conclusions the pupil must reach, including propositions that are historically contested and one the book's own narrative treats as a grievance.
Counter-evidence, at equal prominence: The identical template is legitimate elsewhere in the same board's books: its Physics 9 sets “Justify that distance, speed, time, mass, energy and temperature are scalar quantities”, where the proposition is demonstrable. Its Geography 7 and 8 set genuinely open tasks. The form is only ideologically loaded when the proposition is contestable.
A finding states and cites; it does not argue. The argument is in the studies. Where a finding has counter-evidence it is printed above, in the same block, because a finding that hides its counter-evidence is a worse finding rather than a stronger one.

The checksum is of the exact file these findings were computed from, so anyone can prove they hold the same bytes. The retrieval date is when this copy was fetched to the project's own disk, not a formal web-archive capture. Boards and mirrors reprint and reorganise continuously, so a source link may not resolve, and may not serve the same edition if it does. The bibliographic record above — board, class, subject, medium, curriculum, edition, approval reference and page count — is what identifies the book; the link is a convenience. This project does not republish the PDF itself, for the copyright reasons set out in about.
Identifiers and permanent link

| Permanent link | /books/btbb-physics-9-en/ |
| This record as data | /books/btbb-physics-9-en.json · whole dataset |
The record ID is an accession number that happens to be readable. It never changes, even if the metadata encoded in it turns out to be wrong — if this book's board, class, subject or medium is corrected, the correction appears in the fields above and the ID stays as it is. That is the only way a link made today still resolves in ten years. The full rule is in the standards.

If the edition is misidentified, a score does not survive its evidence, the source link is wrong, or a passage is unfairly characterised, that is worth reporting and will be acted on whether or not the correction suits the argument. Corrections are published in the corrections log, never quietly patched. This applies fully to the board that publishes this book: any reply will appear beside the finding it concerns, under the right of reply.
