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 astronomy problem:
We know that the average distance between the Earth and the Moon is 384,400 km, approximately.
Write that distance in metres, centimetres, and millimetres. Express the amounts obtained in powers of 10.
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
In this activity, the distance from Earth to the Moon is calculated in different units of the metric system. The result will be expressed using powers of 10.
