Splitting the atom before the atom had been split

Summary

The article discusses how science fiction authors like Karel Čapek and H.G. Wells predicted the discovery of nuclear fission and its applications, years before scientists like Ernest Rutherford and Enrico Fermi made breakthroughs in the field.

Highlights

• Karel Čapek's novels "The Absolute at Large" (1922) and "Krakatit" (1924) explored the possibilities of nuclear fission.
• H.G. Wells' novel "The World Set Free" (1914) predicted the discovery of atomic energy.
• Ernest Rutherford's experiments led to the discovery of radioactive elements and nuclear reactions.
• Enrico Fermi's work on neutron-induced radioactivity paved the way for nuclear fission.
• Leo Szilard's patent described how neutrons could create a nuclear chain reaction.
• The first atomic reactor, the Chicago Pile, achieved criticality in 1942.
• The first atomic bomb exploded over the New Mexico desert in 1945.

Key Insights

• Science fiction authors like Čapek and Wells were able to predict the discovery of nuclear fission by extrapolating from contemporary scientific knowledge.
• Rutherford's dismissal of the practical applications of nuclear energy was proved wrong by Szilard's work on nuclear chain reactions.
• Fermi's experiments on neutron-induced radioactivity were crucial in understanding the process of nuclear fission.
• The discovery of nuclear fission was a gradual process that involved the contributions of many scientists over several decades.
• The development of nuclear energy and nuclear weapons was a major turning point in human history, with far-reaching consequences for politics, society, and the environment.
• The story of nuclear fission highlights the complex interplay between scientific discovery, technological innovation, and societal impact.
• The contributions of scientists like Meitner, Hahn, and Strassman to the discovery of nuclear fission were often overlooked or undervalued, reflecting the social and cultural biases of the time.
