Physicist Jim Al-Khalili concludes his investigation into the relationship between science and Islam. He shows how the scientific revolution that took place in 16th and 17th century Europe had its roots in the world of medieval Islam. He travels across Iran, Syria and Egypt to discover the astronomical advances made by Islamic scholars through their obsession with accurate measurement. He then visits Italy to see how those ideas permeated into the West and helped shape the works of Copernicus.
