When a friend of Madam Curie invited her for a short holiday in Morges, Switzeland, she had to politely decline.
You see, she so happened to have a previous engagement that she had to fulfill. Probably.
Had Marie Curie been deliberately vague regarding her trip to Stockholm for any reason other than modesty at receiving her (second!) Nobel prize? Or perhaps she simply did not think much of it?
Her short letter to her friend, kept in the National Library of Israel's archives tells this little tale. The letter itself is radiation free.
We are happy to provide an English translation of the letter, followed by the original in Polish.
