We go behind the scenes of a new exhibition on India at London’s Science Museum. What can historical objects tell us about India’s rich, and often hidden scientific past? We look at the influential mathematics, metallurgy and civil engineering of ancient India.

The exhibition also contain artefacts from India’s time under the British Empire. We ask how the many years of colonial rule shaped the more recent scientific development of India.

Science journalist Angela Saini presents.
