Can physics do for maths what maths has done for physics?

David Spiegelhalter, one of our favourite experts on statistics, recently joined David Attenborough, Bill Bryson and other eminent contributors on the Royal Society's *People of Science* series. You can watch the video here.

The pioneering mathematician talks about his work, computer science and artificial intelligence.

Natalia Berloff explains how quantum particles, that are both light and matter, help solve infamous NP hard problems.

In this video the structural engineer Ahmer Wadee explains how complex numbers can keep buildings from collapsing.

In this video the mathematician Holly Krieger explains how complex numbers are important in the study of dynamical systems.
