Скачать или смотреть Ep 43 – The Algorithm Master: Unpacking the Kuṭṭākāra (Ancient RSA Algorithm)

In Episode 43 of Ancient Code, Modern Mind, host Harsh Rain delves into Aryabhata’s Kuṭṭākāra algorithm from the Gaṇitapāda of the Aryabhatiya, a groundbreaking contribution to algebra critical for astronomy. The Kuṭṭākāra (Koot-taa-KAA-ra), meaning ‘pulverizer,’ solves linear indeterminate equations (e.g., ax + by = c) for integer solutions, addressing problems like synchronizing celestial cycles for eclipses or calendar adjustments (adhimāsa, avamarātra). Harsh explains its role in finding when cycles, like solar and lunar positions, align, using a recursive process akin to the Euclidean algorithm. This method, elaborated by Brahmagupta, showcases India’s advanced number theory, surpassing contemporary Greek and Babylonian approaches. The episode connects the Kuṭṭākāra to modern cryptography, where integer solutions and modular arithmetic underpin secure digital communication, highlighting Aryabhata’s enduring mathematical legacy. Engaging and technical, this episode celebrates the algorithmic brilliance of ancient Indian mathematics.
