Avicenna designs a high-precision angular instrument

The Vikram lander touched down at high southern lunar latitudes.

The landing made India the first country to soft-land in the Moon’s high southern latitude region.

The lander brought instruments for local study; later results should be dated to their separate announcements.

The successful descent created the opportunity to deploy a small rover for lunar surface exploration.

The paper gathers evidence on his observations, instruments, longitude methods and criticism of predictive astrology.

Avicenna defended mathematical and observational study of the heavens while rejecting claims of certain prediction about human affairs.

The publication argues that standard accounts understate how his astronomical work influenced Islamic and Latin traditions.

The publication places manuscript astronomy, pharaonic timekeeping and Indigenous seasonal knowledge within a long continental history.

The authors ask who produces, validates, publishes and owns knowledge generated by African researchers.

African research may be performed locally while prestige, archives and citation systems remain concentrated outside the continent.
