It is impossible to have a conversation with Rohit Gupta that is not labyrinthine. It starts off with his experience of trying to explain to his rickshawwala one morning that it is the earth which is moving around the sun. Somewhere along the way, it touches upon neutrinos (subatomic particles) and God Particle, meanders through his childhood in Jaipur, and comes back to his current love and muse, astronomy.

As ‘Compasswallah’, Rohit Gupta aims to trace the history of astronomy by taking participants back to where it came from. Pic/Satyajit Desai
