An Aberdeen-born scientist has picked up his prestigious Nobel Prize for Physics at a ceremony in Stockholm.
Professor Michael Kosterlitz, 73, will share the 8 million kroner (£727,000) prize with David Thouless and Duncan Haldane after making discoveries about strange forms of matter.
The trio’s discovery “revealed the secrets of exotic matter”.
Mr Kosterlitz is now a physics professor at Brown University in Providence, Rhode Island.
Mr Kosterlitz, who lived in Cults, attended the city’s Robert Gordon’s College between 1948 and 1959.
He left at the end of S4 to transfer to Edinburgh Academy in preparation for his entrance exam to Cambridge University.
Speaking at the time when it was announced he had won, Mr Kosterlitz said: “It was a piece of work that I did as a very ignorant post-doc.
“Complete ignorance was actually an advantage because I didn’t have any preconceived ideas.
“I was young and stupid enough to take it on.”
