Episode 57 - Yavanesvara - The Lord of the Greeks

The Silk Road carried spices, gemstones, ideas... and, occasionally, trigonometry.

In this episode of The Mathematicians Podcast, we follow the mysterious figure known as Yavanesvara, the "Lord of the Greeks," whose translation of Greek astronomical and astrological knowledge into Sanskrit helped spark a mathematical transformation in ancient India.

Along the way, we explore merchant trade across the Indian Ocean, the origins of sine tables, spherical astronomy, navigation, observational error, and the surprisingly rich mathematics hidden inside astrology. We also take a brief detour through gem shops, Roman trade deficits, and the everyday mathematics of merchants using techniques such as double false position and casting out nines.

History remembers Yavanesvara only dimly, but the mathematical journey he represents would help bridge the gap between the early Indian traditions and the age of Aryabhata.

Because sometimes the most important travellers don't carry goods; they carry ideas.
