Error and Discovery: Why Repeating Can Be New
The fascinating story of the discovery of nuclear fission began with an error that earned Enrico Fermi (see picture) a Nobel Prize for the apparent but incorrect discovery of the transuranic elements. Careful repetition and extension of the experiments finally led to the correct interpretation by Hahn, Meitner, Strassmann, Frisch, and Bohr as an effect from nuclear fission of the “small impurity” of (0.7 %) contained in natural uranium.
