Dr Michio Kaku narrates his ideas. This excellent series about the applications of modern science, in areas such as artificial intelligence, biotech and quantum physics etc is being repeated. I think it's being shown on BBC2 every wednesday at 11:20pm. I think he's rather over-optimistic but it's definitely worth a look.
