#radium
On this day in 1903 Pierre Curie, accompanied by Marie Curie, gave a Friday Evening Discourse at the Ri, simply titled ‘Le Radium’.
That same year Pierre and Marie were awarded half of the Nobel Prize for Physics for their work on the spontaneous radiation discovered by Henri Becquerel, who was awarded the other half of the Prize.
Pierre Curie used an early sample of radium during his Discourse demonstration and stored it in this copper alloy pot and box, which are still radioactive to this day.
