Monday, September 30, in Płońsk was dedicated to the memory of Jan Jędrzejewicz (1835-1887) – a doctor, meteorologist and outstanding astronomer, resident of Płońsk. On this day, the 12th edition of the Scientific Award named after Jan Jędrzejewicz for the best Polish-language book devoted to the history of science and technology was determined. The subject event was organized jointly with the Polish Academy of Sciences. In addition to the speeches of the winners for 2023 (the award funded by the Płońsk City Council was awarded to Przemysław Dominas for the book “Central Trans-Andean Railway Callao – Lima – La Oroya, the work of the Polish engineer Ernest Malinowski”), there was a lecture on the use of artificial intelligence in astronomical research. The mayor of Płońsk, Andrzej Pietrasik and numerous school students laid flowers and lit candles on the grave of Jan Jędrzejewicz. Shortly afterwards, a charming mural by Tytus Brzozowski was unveiled (on two buildings, ul. Grunwaldzka 28 and 35) commemorating Jan Jędrzejewicz. The students presented a performance referring to astronomy, the hero of the city and the tragic fate of its Jewish inhabitants. The Planetarium and Astronomical Observatory in Płońsk showed one of the eight films available there, including two in 3D format, followed by Adam Derdzikowski (in the photo) from the Płońsk Astronomy Lovers’ Club. Jan W. Jędrzejewicz, coordinator of the Planetarium and co-organizer of all celebrations that day, presented sunspots through a telescope placed under the observatory dome.Jan Jędrzejewicz will be mentioned at a temporary exhibition organized by the Polish Armenian Culture and Heritage Foundation, which will present various figures from the Jędrzejewicz-Jędrzejewicz family.
