29.09, one hundred and twenty-one years ago, the nuclear physicist Enrico Fermi was born.
At the age of 27, Fermi became a member of the Royal Academy of Italy. At that time Mussolini ruled the country and all civil servants had to accept the Fascist ideology. At first, Fermi, like many others, agreed to this. However, after nine years of his life, he changed his attitude to this regime and began to oppose it. The consequence was the loss of his job.
He discovered the nuclear reactions occurring under the action of neutrons. For this, he soon received the Nobel Prize.
After leaving with his family for Stockholm to receive the prize, Fermi decided not to return to Fascist Italy. Instead, he moved to the United States and became a professor at Columbia University.
And at this time he was very puzzled by a question expressed by the famous Fermi paradox:
"On the one hand, numerous arguments are made for the fact that there must be a significant number of technologically advanced civilizations in the universe. On the other hand, there are no observations to support this. The situation is paradoxical and leads to the conclusion that either our observations are incomplete and erroneous. Well, where are they then?"
