Enunciat
Sophia Brahe was a Danish astronomer in the 16th and 17th century who worked with her brother Tycho Brahe, also astronomer, in the creation of a star catalogue that Kepler used as a source to find the laws on the movement of planets in the Solar System. She made the observations on the lunar eclipse of December 1573.
In this context we propose you to solve the following geometry problem:
Looking up at the sky, we notice ten stars in the following position:
Draw eight different triangles with their vertex in some of those nine stars. Classify the triangles obtained.
Observacions i context
- Sophia was self-taught with the help of her brother Tycho. She faced her family, who did not accept that high-society members did anything else in their life other than idleness.
- Some important astronomers previous to Sophia Brahe are Enheduanna (c. 2285 BC – c. 2250 BC) who is considered the first astronomer in history, Aglaonice of Thessaly (c.500 BC – c. 400 BC), Theano of Crotone (c.546 BC – c. 450 BC), Hypatia of Alexandria (c. 370 – c. 416), Fátima de Madrid (c. 900 – c. 1100) and Anna Komnene (1083-1153).
- Other relevant scientists of the 17th century that can be highlighted are Caterina Vitale (pharmacist and chemist), Maria Cunitz (astronomer), Martine Bertereau (specialist in mine engineering and mineralogist), Margaret Cavendish (a prolific writer who wrote 10 natural philosophy books, now physics), Marie Crous (mathematician), Marie Meurdrac (chemist), Elisabeth Hevelius (astronomer), Jeanne Dumée (astronomer), Maria Margarethe Winckelmann-Kirch (astronomer), Maria Sibylla Merian (entomologist, naturalist, explorer, science illustrator and painter), and Maria Clara Eimmart (astronomer).
Descripció
The goal is to draw and classify several triangles in a 3x3 grid.
