The world of the history of classical Indian astronomy has lost one of its brightest minds, Dr. Balachandra Rao, a scholar who dedicated his life to decoding ancient astronomical algorithms and combating misinformation in the name of Vedic science.
Dr. Rao’s expertise lay in unravelling the complex astronomical algorithms of ancient Indian texts. His research made obscure Sanskrit mathematical and astronomical treatises accessible to modern readers, revealing the sophistication of classical Indian science. He demonstrated how scholars like Aryabhata, Bhaskara, and Varahamihira developed precise methods for calculating planetary positions, eclipses, and timekeeping. Rao dedicated his life to decoding India’s rich intellectual heritage, ensuring that genuine scholarship prevailed over myth.
Inspired by the Gandhian-Marxian H. Narasimhaiah, a Kannada scholar, scientist, and freedom fighter, Dr Rao read Marx, Russell, and Advitha and, in his words, adapted a rational worldview.
Dr. Rao was deeply troubled by the false claims surrounding Vedic knowledge. Determined to separate fact from fiction, he authored Vedic Mathematics and Science in Vedas (also available in Kannada as Vedic Mathematics Mattu Vedagalalli Vijnaana). In this work, he meticulously examined popular claims, clarifying what was genuine and myth while systematically investigating the intricate aspects of classical Indian astronomy. His commitment to rational inquiry extended to other notable works. Tradition, Science and Society and Astrology – Believe It or Not?—both translated into Kannada. I would recommend all to read these books and benefit from it.
His book, Indian Astronomy: Introduction, is an essential read for anyone interested in learning about India's classical astronomical tradition.
In an era when ancient knowledge is often politicised or romanticised, Dr. Balachandra Rao was a guardian of reason. His passing leaves a void, but his meticulous approach to India's astronomical heritage will continue to inspire future researchers.
He was one of the key people who got me interested in Indian classical astronomy and suggested that I examine older Tamil works related to astronomy/astral sciences. Through his works, he demonstrated how to honour tradition through truthful understanding rather than uncritical glorification.
My salutes!
