Professor Dwivedi Memorial Lecture
Professor T.D. Dwivedi joined Concordia University in 1965, then known as the Sir George Williams University, and retired 32 years later in 1997.
The Professor T.D. Dwivedi Memorial Lecture Series is possible thanks to a generous contribution from the Dwivedi Family.
This sixth lecture in the series, presented by Dr. Kim Plofker, is entitled, “Sticks and Shadows: The Ingenious Mathematics of Medieval Indian Timekeeping."
