Lasers are the focus of this year's Nobel Prize in Physics, which recognizes "optical tweezers" and a "method of generating high-intensity, ultra-short optical pulses". But what does that mean?

Theoretical physics professor Hans Hansson, who is also a member of the Nobel Committee, joins Radio Sweden to shed some light on the scientific inventions and why they're so important that they deserve a Nobel Prize.
