Friendship with Science - Ep4 - Atoms Pt. II - Prof. K Sridhar, Shashi Thutupalli, Biswa Kalyan Rath

Friendship with Science is a series of fun conversations with a range of scientists in India about science that is done here but is of course relevant universally, as all good science always is! The conversations will cover fundamental and broad ideas in science – they will range from atoms to genes, they will go as far out as the sun and come as close to home as making science toys with everyday objects. The conversations will flow across traditional disciplinary boundaries – they will be about physics, but also biology. They may start in chemistry but meander through mathematics. They will be about how science is done and how scientists think. What excites them? How do they work? Are they really machines that turn coffee into theorems and laws? In short, this series is an invitation to make friendship with science and scientists with a splash of laughter mixed in!

This episode continues the conversation on atomism with K Sridhar, a Physicist and Professor at the Azim Premji University in Bangalore and previously at the Tata Institute of Fundamental Research in Mumbai. In the conversation we start from the initial ideas of quantum mechanics, their connections with the theory of relativity eventually leading to particle physics and the standard model.

Taking the conversation up with Prof. Sridhar are Shashi Thutupalli, who may or may not be a scientist and Biswa Kalyan Rath, who is definitely not a comedian!
