In 2023, the FSB began subjecting dissenters to punitive psychiatry. Corresponding Member of the Russian Academy of Sciences Sergei Abramov left the psychiatric hospital after the examination and became familiar with the updated version of the charges. T-invariant spoke with the scientist about his life with the “extremist” label, his political views and the reasons for the security forces’ attack on the Russian supercomputer industry.
Within the project "Creators" supported by Richard Lounsbery Foundation T-invariant together with RASA (Russian-American Science Association) continues to publish a series of biographical essays about people from Russian Empire, who made a significant contribution to world science and technology. The essay is dedicated to astronomer Alexander Vysotsky. He had worked at the observatory of the University of Virginia. There he compiled the first catalogue of red dwarfs and experimentally confirmed the rotation of our Galaxy.
