Prof Peter Higgs has received his Nobel prize for physics at a ceremony in Stockholm.
The Edinburgh University emeritus professor shared this year's physics prize with Francois Englert for work on the theory of the Higgs boson.
In the 1960s, they were among the physicists who proposed a mechanism to explain why the most basic building blocks of the Universe have mass.
Winners in other Nobel categories will also receive their awards at the event.
These include this year's laureates in chemistry, economics, medicine and literature.
Sweden's King Carl Gustav presented Prof Higgs with his Nobel medal at the Stockholm Concert Hall just before 1600 GMT.
Higgs was at Edinburgh University when he came up with the theory. Th
