THE RISE AND FALL OF THE ATOM (An illustrated lecture by D. H. Hamilton and the Physics Department) It has been an eternal question whether the scientist should consider the moral consequences of his invention or discovery. Gatling and Mills were boffins who did what was asked of them, and their contribution to destruction is only exceeded by that of the 'Manhattan Project' in degree, not in principle. So the solemnity of the last part of this presentation, with the 'Threnody for the victims of Hiroshima' and 'A song about Major Eatherley', left an unanswered question: can the fearful ruin caused by the atom bomb be balanced against the lives that were not sacrificed in a projected 'conventional' attack on Japan, and against the lives of thousands of starving and despairing war prisoners saved by the bomb's timely delivery ? Of course it was right that we should have been left to reflect on this ultimate power that man has given himself; and the fascination of the evening was in watching man's resistless progress towards it. Giving the ancients the chance to speak for themselves made a lighthearted but useful approach. We at once felt the sense of awe in the presence of men in whom wisdom was more prominent than expertise; but we could also enjoy the eternal human weakness of scientists who must disagree with each other until they can be convinced by experiment; and how pleasing to see that the first experiment needed brute force rather than scientific skill. Soon we were in the realms of skilled scientific experiment carried out with consummate ease; and when we were told 'this one you can do for yourselves', we knew that if we tried we would certainly get it wrong and be left wondering why. Mr. Hamilton has the happy ability to expand without pomposity the distillation of the learning of 2,50o years; and furthermore he manages to use his audience, even those of us who are ignorant, and to leave us thinking that we are potentially quite clever. As time went on we began to think we really could appreciate that a ten-inch gold ingot contains 6o million million atoms, and we felt we could consult a periodic table as confidently as a calendar, since the audience had been turned into the periodic table. `Charged particles' suggests something very modern until we found that the ubiquitous Aristotle had used them to cure gout, and that some of his contemporaries had used a piece of amber to produce the effect that Thomson was to refine and explain in the Cavendish at Cambridge. Is there 'nothing new under the sun' ? 38
