Description

A hundred years ago, in the first days of June 1925, Werner Heisenberg, then 24-year-old Privatdozent and assistant to Max Born at the University of Göttingen, fell ill with hay fever. The symptoms of the disease were so severe that his boss, himself an allergy sufferer, decided to give his subordinate a 2-week holiday. He also suggested a trip to Helgoland, a small island in the North Sea, known for its climate beneficial to those suffering from respiratory ailments.

Indeed, a few days spent surrounded by the sea breeze and far from the pollen-bearing grasses of the Harz Mountains cured Heisenberg and allowed him to return to his earlier calculations. Finally he finished them after several nights of work, and then, in the dawn, it became clear to him that he found the proof of the validity of his earlier concepts.

 

Today we know that this dawn over the Helgoland meant not only another day, but also the emergence of a new physical theory that has changed the world for the 20th century. And it has beeing it all the time…

 

I invite those who would like to hear a few details of this story to come to the IFJ Auditorium. I hope that spending one hour there  will not be for them a waste of time.
