A new history of ideas presented by Melvyn Bragg but told in many voices.

Melvyn is joined by four guests with different backgrounds to discuss a really big question. This week he's asking how has technology changed us?

Helping him answer it are Archaeologist Matt Pope, the Surgeon Gabriel Weston, the technologist Tom Chatfield and the historian Justin Champion.

For the rest of the week Matt, Gabriel, Tom and Justin will take us further into the history of ideas about technology with programmes of their own. Between them they will tell us about Plato and the internet, medieval medicine, tool use in human evolution and the origins of Modern Science.
