Enunciat
Sofya Aleksandrovna Yanovskaya, a Russian mathematician of Jewish origin of the 20th century specialist in logic, posed different problems to her students so that they would solve them with perseverance and so that they would continually ask themselves: what am I doing? where am I going?
We propose you to solve the following mathematical logic problem.
Look at this list of numbers: 1 1 3 4 4 4 5 5 5 6. You have to place them in the circles of the drawing, keeping in mind that the number that is written in each triangle is the product of the three that are in the vertices. Where does each number go?
Observacions i context
- As a revolutionary, she took an active part in politics with the communist party during the Russian Revolution, first underground and then as the editor of the Kommunist newspaper in Odessa.
- Sofya's predecessors, who also stood out in the field of mathematical logic, are Elena Lucrezia Cornaro Piscopia (1646-1684); Ada Lovelace, precursor of computer language (1815-1852); and Christine Ladd-Franklin (1847-1930).
- Her contemporaries were also renowned scientists such as Priscilla Fairfield Bok (1896-1975), American astronomer; Mary Lea Heger (1897-1983), American astronomer; Gertrude Blanch (1897-1996), American mathematician; Mary Taylor Slow (1898-1984), British physicist and mathematician; Marguerite Lehr (1898-1987), American mathematician; Charlotte Moore Sitterly (1898-1990), American astronomer; Odette Jasse (1899-1949), French astronomer; Vera Fedorovna Gaze (1899-1954), Soviet astronomer; Pelageya Polubarinova-Kochina (1899-1999), Soviet mathematician; Gertrude Mary Cox (1900-1978), American mathematician and statistician; Ida Rhodes (1900-1986), American mathematician; or Mary Lucy Cartwright (1900-1998), British mathematician, among many others born in the early 20th century.
- Important researchers such as Isabella Grigoryevna Bashmakova (1921-2005) and Olga Arsenievna Oleinik (1925-2001) stand out among her students.
