About the Author

Sri Narasimha Patrudu is an engineer by profession and a researcher by passion. He holds an M.Tech in Thermal Engineering from the National Institute of Technology (NIT) Warangal. Professionally, he is the developer of FireCAD—a specialized software for steam boiler design—and the founder of a boiler manufacturing company.

Beyond his daily work in thermodynamics and industrial design, he holds a deep, lifelong interest in Sanatana Dharma and the history of science. This curiosity was first nurtured by his late father, Sri Chiranjeevi Patrudu, and heavily inspired by the teachings of Swami Vivekananda.

In writing Zero to Gravity and establishing BharatWisdom.com, his goal is to bring an analytical, engineering perspective to the study of ancient Indian texts. He does not claim that ancient scholars possessed modern laboratories or contemporary instruments. Rather, his work attempts to demonstrate how foundational concepts in mathematics, astronomy, medicine, and engineering were systematically studied in India centuries before their formal articulation in the modern world.

He offers this work to encourage genuine intellectual inquiry and historical continuity, rather than sensationalism. He invites readers to explore these traditions not as myths, but as documented early contributions to humanity’s shared scientific heritage.
