A three-year-old went with his dad to see a litter of kittens. On returning home, he breathlessly informed his mother there were two boy kittens and two girl kittens.

"How did you know?" his mother asked.

Antonio Abetti

Died 20 Feb 1928 at age 81 (born 19 Jun 1846).Italian astronomer who was an authority on minor planets. At first a civil engineer, he became an astronomer at the University of Padua (1868-93), with an interest in positional astronomy and made many observations of small planets, comets and star occultations. In 1874, Abetti went to Muddapur, Bengal, to observe the transit of Venus across the sun's disk where his use of a spectroscope was the first use of this kind. Later, he became director at the Arcetri Observatory and Professor of astronomy at the University of Florence (1894-1921). The observatory had been founded by G. B. Donati in 1872, and Abetti equipped it with a new telescope that he had built in the workshops at Padua. He was active after retirement, until his death, and was followed by his son Giorgio.
