Reframes, rethinks and bold calls: 16 speakers share ideas at TEDGlobal>London

In 1831, Michael Faraday stood in a lecture hall and demoed an idea that changed everything: electromagnetic induction. This work paved the way for widespread use of electricity.

On September 29, 2015, in the same lecture hall, attendees gathered for TEDGlobal>London to hear more ideas with the potential to shift reality. Sixteen TED speakers shared insights on the issues that matter most in the world right now: the refugee crisis, poverty and ethical science. Oh and, of course, spam email.
