In the first decades of the 20th century, physics was revolutionised with developments in the understanding of the nature of atoms. InPierre and Marie Curie discovered that pitchblendean ore of uraniumcontained a substance—which they named radium —that emitted large amounts of radioactivity. Ernest Rutherford and Frederick Soddy identified that atoms were breaking down and turning into different elements. Hopes were raised among scientists and laymen that the elements around us could contain tremendous amounts of unseen energy, waiting to be harnessed.
