Earlier this year the BBC organised a ‘science festival’ in Uganda. One of the practical outcomes of this was to put physics teachers in East Africa in touch with physicists involved in the Higgs boson discovery at CERN. As a result, several teachers from the region visited CERN and took part in their international teacher programmes.

In Discovery this week we look at the impact of their visit and ask how international ‘big science’ projects such as CERN can offer practical development help – especially in sub Saharan Africa.
