md **Stage 2 (模仿 — Imitate):** She replicated Becquerel's methods to verify his findings, using similar equipment and procedures. She adapted his approach to measure the electrical conductivity of air ionized by radioactive materials, using an electrometer developed by her husband Pierre. **Stage 3 (理解/应用 — Understand/Apply):** The critical Stage 2→3 jump: Curie systematically compared uranium with thorium (discovered independently by Gerhard Carl Schmidt in 1898). She made deliberate trade-off decisions about measurement methods and concluded that radioactivity was a property of the atom itself — not of molecular compounds — a genuinely novel interpretation that contradicted prevailing assumptions. **Stage 4 (创造 — Create):** The isolation of polonium and radium (1898) required inventing new methods. There was no existing protocol for isolating previously unknown elements from uranium ore. She and Pierre created the methodology. She then distilled the principle: radioactivity as a characteristic of atomic structure, not chemical bonding. > "I proposed to examine whether other substances besides uranium compounds were capable of emitting similar Becquerel rays. The results of the examination of the various compounds showed that the property of emitting these rays is a specific property of the uranium atom." > — Curie, M. (1903). *Radioactive Substances* (doctoral thesis), translated and reprinted. https://www.biodiversitylibrary.org/item/107855 **Stage 5 (进化 — Evolve):** Curie's Nobel Prize lectures (1903, 1911) demonstrate Stage 5: she reflected on the entire trajectory of radioactivity research, identified what her framework explained and what it did not, and proposed the next generation of questions — restarting the acquisition cycle at a higher level. Her 1911 Nobel lecture for Chemistry explicitly revisited and refined the framework she had proposed in her 1903 Physics lecture.
