Action Quote by Marie Curie
“Certein bodies... become luminous when heated. Their luminosity disappears after some time, but the capacity of becoming luminous afresh through heat is restored to them by the action of a spark, and also by the action of radium.”
About This Quote
Source Scientific Lecture: 1912, Radioactivity Research
The passage describes how certain materials emit light when heated, lose it, but can be re‑energized by a spark or radium, illustrating reversible luminescence.
In simple terms: Some substances glow when heated, dim, then can glow again with a spark or radium.
