An exhibition on 1,000 years of science from the Muslim world opens today at the Science Museum in London.
Entitled "1001 inventions: Discover the Muslim Heritage in Our World", it focuses on the forgotten triumphs of Muslim science and technology.
Included are medieval medical instruments, a model of Zheng He's 100 metre long Chinese junk ship and a six metre high 13th century clock.
The BBC's Nick Higham speaks to Professor Salim Al-Hassani, chairman of the exhibition and Yasmin Khan, a Science Museum curator.
