One photon's journey: Saul Perlmutter

Nature Video presents short films from the annual Meeting of Nobel laureates in Lindau, Germany. The films capture the views of young scientists and Nobel Laureates as they discuss the future of their subjects and the nature of scientific discovery. In 2014 the meeting was all about Physiology and Medicine, a topic last covered at the meeting of 2010. In 2013 & 2009 the meetings were dedicated to Chemistry, and in 2012 and 2008 they were dedicated to physics. In 2010, Lindau hosted a special cross-disciplinary get-together to celebrate the 60th anniversary of this unique meeting of minds. From 2009, these films have been made with the support of Mars, Incorporated.
