  "note": "Nine chapters, of which two are Punjab-only: Magnetism, which neither Sindh nor KP teaches at grade 9, and chapter 9, \"Nature of Science\", whose learning outcomes require pupils to distinguish classical, quantum and relativistic mechanics and to \"Explain, with examples in Physics, falsifiability as the idea that a theory is scientific only if it makes assertions that can be disproven\" (p.181). Explicit Popperian falsifiability instruction appears nowhere else in the corpus, and the same chapter is where nanotechnology and artificial intelligence enter (pp.192-193). Punjab uniquely drops Gravitation. A1 is 1: the translated bismillah on PAGE 1 and nothing else, chapter 1 opening on measurement - a clean contrast with KP Physics 9, which opens with a page of Quranic verses and an \"Islamic World Contribution to Physics\" panel. The only named Pakistani scientist here is Abdus Salam (p.56), in a secular frame. A7 5 on absence: twelve female-marked tokens, mostly he/she generics.",
