Some of Cambridge's finest minds are among those honoured in the Queen's Birthday Honours.
Professor Harry Bhadeshia is knighted for his work on metals at the University of Cambridge.
Professor Bhadeshia invented a particular kind of steel that's used for railway tracks, as well as the world's strongest armour - known as ‘super bainite’ – in part through the discovery of a steel that seemed to sing.
He's applied physics and mathematics to predict what shapes the crystals in metals will take under certain conditions, and with certain elements added or taken away.
Professor Bhadeshia arrived in London in 1970 (his Indian parents had been forced to leave their home in Kenya by political changes) as a young teenager and has worked his way up from technician, through part-time study, to become the University of Cambridge’s Tata Steel Professor of Metallurgy.
Other scientists on the honours list include the university's Professor James Jackson, an expert in seismology. He'd warned that the Nepal earthquake was an accident waiting to happen.
Professor Jackson is head of the Department of Earth Sciences and has explored continental tectonic formations in areas of active plate movement such as Africa, Iran and the Aegean.
