1963 Nobel Prize in Physics

The 1963 Nobel Prize in Physics was awarded to Emilio Segrè and Maria Goeppert Mayer for their groundbreaking discoveries about atomic nuclei. Segrè was recognized for discovering antiprotons, a new type of subatomic particle that is the antimatter counterpart of protons. Mayer received the prize for developing the "shell model" of the atomic nucleus, which explains how protons and neutrons are arranged inside atoms. Their work enhanced our understanding of atomic structure and fundamental particles, deepening knowledge of matter's building blocks and the forces that hold them together.
