![]() ![]() They were among the many scientists and engineers who had taken part in the Manhattan Project, which developed the atomic bombs that the US dropped on Hiroshima and Nagasaki in August 1945.Ĭhicago was where the Italian physicist Enrico Fermi had in 1942 designed and built the first reactor that could achieve a self-sustaining nuclear reaction and where much of the science of the Manhattan Project was incubated. But the clock actually emerged from the concerns of the physics community immediately after the Second World War, when two University of Chicago physicists – Eugene Rabinowitch and Hyman Goldsmith – started to think about the consequences of their work. The annual resetting of the Doomsday Clock is these days a major media event, providing grist for politicians, policy-makers and commentators around the world. In setting the clock to 100 seconds to midnight, they cited risks such as worsening nuclear threats, a lack of climate action, and the rise of “cyber-enabled disinformation campaigns that undermine society’s ability to act”. This year’s historic decision was announced to “leaders and citizens of the world” at the National Press Club in Washington, DC by members of the Bulletin of the Atomic Scientists. But on 23 January 2020 the clock was moved closer to midnight than at any other time in its near 75-year lifetime. and over the years has shifted backwards and forwards as the global situation has worsened or improved. That’s according to the Doomsday Clock – a device created by the Bulletin of the Atomic Scientists in 1947 as a metaphor to indicate how near we are to a humanity-ending catastrophe.
