Michio Kaku: physicist
Sharing his favourite websites with us this week is a man who, for his high school science fair project, built a 2.3-million-electron-volt particle accelerator in his parents' garage. He went on to co-found string field theory, a leading contender in the search for a scientific 'Theory of Everything'. Mark one for Wikipedia, then, which Michio Kaku says he uses to research his books.
Michio Kaku's choices were Science Daily, Wikipedia, and the research library of the Los Alamos National Laboratory.
