The history of the compass should distinguish magnetic direction-finding from its use in sea navigation.
Documented context#
The Smithsonian’s navigation timeline cautiously suggests that maritime compass use may have begun in China after 1000 CE. Its wording expresses uncertainty rather than one confirmed invention day or sole inventor.
Evaluating an account#
Ask which application a date refers to. A magnetic device, a written description and evidence of use aboard a ship answer different questions. Retain qualifiers such as “may” when summarizing a cautious historical source.
Scope#
The reading questions are editorial suggestions. This brief introduction does not claim an exhaustive history or a quantified modern impact.
