The Discovery of Fission and a Nuclear Physics Paradigm, we find that the maps are worse than we might have expected. Some main features have not been mapped at all, or their shape and nature have been poorly explored. And this brings us to the general problem of how to map scientific work. When we study the history of fission we find a type of terrain —作者: noxious 時(shí)間: 2025-3-22 09:04 作者: Ferritin 時(shí)間: 2025-3-22 13:14 作者: 厭倦嗎你 時(shí)間: 2025-3-22 18:14 作者: Limpid 時(shí)間: 2025-3-23 01:13 作者: Abrade 時(shí)間: 2025-3-23 03:30

Whether or not that is the case with Otto Hahn’s discovery of nuclear isomerism is a matter we shall return to later. In the meantime, let us think back to the period before 1921.
