FREDERICK SODDY
The lecture was on radium and the radioactivity that scientists had recently discovered. This appears to be the first time a scientist suggested the possibility of using atomic energy to produce a powerful weapon. At the same time, note that he also mentioned the possible destruction of the earth. “Heavy matter” referred to the elements—many of which had not yet been discovered—that had larger atomic numbers than radium like uranium.
Most scientists do not have the skill or the totality of knowledge to accurately predict the effect of scientific research and learning on society. Many are not interested. Those who try to communicate with politicians and the public are usually met with indifference or suspicion. Above all, the scientific and mathematical literacy of the public is so weak, that it is impossible in much of science to even explain the science to the lay public much less explain its implications. Soddy was a bit of an idealist from a class society and he felt the upper classes should be better informed by scientists.
Frederick Soddy FRS was an English radiochemist who explained, with Ernest Rutherford, that radioactivity is due to the transmutation of elements, now known to involve nuclear reactions. He also proved the existence of isotopes of certain radioactive elements. He was a polymath who mastered chemistry, statistical mechanics, finance and economics.
