The Nobel winning scientist who discovered the existence of the 'godparticle' will open a new exhibition at the Science Museum today.
Professor Peter Higgs will tour the new one million pound"Collider" exhibition - the most ambitious exhibition at the museum to date.
The exhibition will be devoted to the Large Hadron Collider (LHC), the giant atom smashing machine based at the CERN laboratory in Switzerland, which confirmed the particle's existence last year.
The Museum hopes to recreate what life is like at the particlephysics laboratory near Geneva.
