| Video Discription | About the Talk: In this talk, the speaker presents ‘Sources and Texts’, discussing Indian advances in Astronomy from an ancient period all the way to the modern period. The speaker establishes the great antiquity of Indian astronomy and quells the distorted narratives spun by the left academia. The story spun by the Linguistics theories position India as a young civilization, which long after the onset of “Aryans” in 1500 BCE became literate. Western accounts assert that Indians learnt their astronomy via Babylon and Ancient Greece. However, textual accounts of Indian Astronomy encode phenomena far more ancient that the assertions made by the Linguistic theories are blown out of the water. With this end in mind, the speaker brings out contrary evidence in various sources and texts ranging from Purana literature with stories encoding astronomy to Siddhanta texts with mathematics of celestial bodies. It becomes clear how from ancient times, Indians created celestial calendars for time-keeping, and in the process, recorded various astronomical phenomena. The development of mathematical tradition in astronomy for the purposes of modelling, measuring, tracking and prediction of celestial bodies becomes apparent. These models also underwent refinement as over time effects of precession and modelling inaccuracies became prominent. The speaker also presents works of famous ancient Indian astronomers and thus, seals the discussion on the antiquity of Indian astronomy and the Indian civilization itself. About the Speaker: Dr. Raj Vedam is an Electrical Engineer with decades of experience in Power, Electronic Design Automation, and Oil & Gas Industries. He is based in Texas, USA. As an Applied Mathematician and Historian of Sciences, his research reveals the great antiquity of the Indian Civilization with strong advances in several areas of applied sciences. He has worked on revision of history textbooks in Texas, Telangana, and Andhra Pradesh. In addition to his professional work, he is also a Visiting Faculty at Hindu University of America where he offers two courses on the Deep History of the Bharatiya Civilization & Knowledge Systems.
