Higgs boson event, ATLAS detector C013/6892

Higgs boson event. Graphic of a transverse section through a detector showing one of the numerous particle collision events recorded during the search for the Higgs boson. This event (a proton-proton collision) was recorded with the ATLAS (A Toroidal LHC Apparatus) detector on 10 June 2012. The collision produced two muon pairs (red tracks). This is part of the enormous amount of data collected to enable confirmation of the theories being tested. In the Standard Model, the Higgs boson is used to explain why particles have mass. CERN (the European particle physics laboratory) announced the Higgs boson discovery on 4 July 2012

LCC-LFB Fire display at Brigade HQ Southwark

The London Fire Brigade encouraged, for very many years, a good public image by opening its doors to the public to special fire brigade displays. On Saturday afternoons, during the summer months, it was a regular feature to see displays at the Southwark Headquarters. As the picture shows it drew large, and frequently a boater-hatted, crowds. A motorised fire engine works two firefighting jets, while a turntable ladder is fully extended to the top of the drill tower. Where there was space to stand and watch the public took every opportunity to do so
