RITCHIE CALDER, the question-master writes: To the scientists the atomic bomb, with all its portentous meaning, and the release of atomic energy, the greatest material advance in the whole of the history of Thinking Man, are just instalments in a serial story. The concern of the pure scientist is to find out what makes the atom "tick." The atom is the infinitesimal structure from which all matter, animate and inanimate, is built. Its nucleus, or kernel, from which atomic energy is released, is complicated. The physicists are discovering the pieces. What is happening behind the headlines is explained here. Scientists try to find what happens next (News (Adelaide, SA : 1923 - 1954), 1951)
