Today Gilberte has saved a young man from a lynching. He had been prescribed baths in hot mineral water, so he came to Karlsbad. But he didn’t know that there were pools dedicated to that purpose. He was queuing at the Sprudel’s pond and, when his turn has arrived, he has undressed in a flash and got into the fountain from which people were waiting to drink. The ladies showed their repulsion by screaming and fainting, while the gentlemen rushed on the trouble maker, who jumped out of the fountain and ran stark naked, chased by a furious crowd. They circled the fountain several times, until nobody knew who the persecuted and the persecutor was. Gilberte took advantage of the confusion to hide the fugitive behind her parasol. And so, the two have moved away from the fuss by walking backwards. The young man has been so grateful that he has insisted on inviting us to lunch. His name is Albert Einstein and he is a recently graduated scientist. During the meal, Gilberte has shown him the results of the water samples collected from the rock’s spring. He has shown a vivid surprise and has explained that the potential energy of nuclear radiation is overwhelming and althougt very few naturally-occurring nuclei are radioactive, it seems that this spring is one of them and the consequences of the ingestion of this water are unpredictable. When Gilberte has told him it’s the spring from which I drink since I am in Karlsbad, his eyebrows have risen above his head, he has jumped up and run away at the speed of light. I bet he’s a nut!
