Maria Goeppert Mayer, born on this day in 1906, changed the field of nuclear physics by explaining the structure of atomic nuclei, a question that had evaded scientists for years.

Atoms consist of a nucleus made up of nucleons - protons and neutrons - surrounded by electrons distributed within shells with a fixed number of electrons. Goeppert Mayer was particularly interested in atomic nuclei in which the number of nucleons corresponded to full electron shells – so-called ‘magic numbers’. These type of nuclei are especially stable but no one knew why.

Goeppert Mayer was intrigued by the problem which she saw as a kind of ‘jigsaw puzzle’. She developed a model in which nucleons were distributed in shells with different energy levels – the nuclear shell model. The puzzle was solved and she went onto receive the 1963 Nobel Prize in Physics.
