Beginning in the late 1910s and early 1920s, Whitehead gradually turned his attention from mathematics to philosophy of science, and finally to metaphysics. He developed a comprehensive metaphysical system which radically departed from most of western philosophy. Whitehead argued that reality consists of processes rather than material objects, and that processes are best defined by their relations with other processes, thus rejecting the theory that reality is fundamentally constructed by bits of matter that exist independently of one another. Today Whitehead's philosophical works – particularly Process and Reality – are regarded as the foundational texts of process philosophy.
During which decade did Whitehead's focus start shifting away from mathematics?
1910s

The United Kingdom and Ireland have separate media, although British television, newspapers and magazines are widely available in Ireland, giving people in Ireland a high level of familiarity with cultural matters in the United Kingdom. Irish newspapers are also available in the UK, and Irish state and private television is widely available in Northern Ireland.[citation needed] Certain reality TV shows have embraced the whole of the islands, for example The X Factor, seasons 3, 4 and 7 of which featured auditions in Dublin and were open to Irish voters, whilst the show previously known as Britain's Next Top Model became Britain and Ireland's Next Top Model in 2011. A few cultural events are organised for the island group as a whole. For example, the Costa Book Awards are awarded to authors resident in the UK or Ireland. The Man Booker Prize is awarded to authors from the Commonwealth of Nations and Ireland. The Mercury Music Prize is handed out every year to the best album from a British or Irish musician or group.
