Observer Research Foundation Chairman Sudheendra Kulkarni has written a letter to Chief Minister Devendra Fadnavis, suggesting that the state should join the international community in commemorating the 100th anniversary of Albert Einstein's 'General Theory of Relativity'.

The Maharashtra government should erect a memorial in honour of Albert Einstein in Mumbai, Kulkarni said. "One hundred years ago this month on November 25, 1915 - Einstein presented his General Theory of Relativity to the world. Among other things, this theory explains the force of gravity in terms of warping of space and time," he said.
