Punished

One day a little girl came home from school, and said to her mother, "Mommy, today in school I was punished for something that I didn't do."

The mother exclaimed, "But that's terrible! I'm going to have a talk with your teacher about this! By the way, what was it that you didn't do?"

The little girl replied, "My homework."

Antonia Maury

Died 8 Jan 1952 at age 85 (born 21 Mar 1866). Antonia Coetana de Paiva Pereira Maury was an American astronomer and ornithologist whose painstaking classifications of stars by their spectra included elaborate work on 681 bright stars of the northern skies published in Annals of Harvard College Observatory (1896), a significant early catalog. Yet she was unappreciated by her observatory director, Edward C. Pickering. Her work was important in Ejnar Hertzsprung's verification of the distinction between dwarf stars and giant stars, as now seen in the Hertzsprung-Russell diagram. After Pickering discovered the first spectroscopic binary star, Mizar, she was first to measure its period, 104 days. In 1889, she identified the second such star, Beta Aurigae, with a period of about 4 days. Antonia was the niece of astronomer Henry Draper, and the granddaughter of John William Draper who pioneered in the use of photography in astronomy.«
