Is this the first year that the Nobel Prizes for Physics, Chemistry *and* Peace have all gone to physicists?! The #NobelPrize for Narges Mohammadi is a reminder, if anyone needed it, that physics students go on to do amazing things - in physics and outside it.
Replying to @NobelPrize
As a young physics student Mohammadi distinguished herself as an advocate for equality and women’s rights. In 2011 she was arrested for the first time and sentenced to many years of imprisonment for her efforts to assist incarcerated activists and their families. #NobelPrize
