A TRAVELLING train exhibition is being organised by the Atomic Scientists' Association with the cooperation of the Ministry of Supply to illustrate the facts about atomic energy and its industrial applications in a simple and attractive manner. The train will visit fifty-five of the principal towns of Great Britain and take a year to complete the course. The information will be conveyed by charts, diagrams and photographs. It is also planned to show some simple experiments as well. At the various stopping places it is hoped to organise 'Atomic Weeks', which will include public discussions, in order to focus attention on the significance of the industrial revolution which will be brought about by the harnessing of atomic energy.
