Giovanni domenico cassini discovery of grse music

From to , Cassini worked at the observatory of Marquis Malvasia in Pianzano, near Bologna, where he continued his astronomical education under the guidance of Giuseppe Biancani and Francesco Maria Grimaldi. Cassini's career is a remarkable example of the changing attitude of the scientific community towards astrology in the 17th and 18th centuries.

Discovery of the interior parts of.

In his youth, Cassini was deeply interested in astrological theories, which eventually led him to pursue astronomy. His reputation as an astrologer played a crucial role in starting his scientific career. The Marquis Cornelio Malvasia, a wealthy amateur astronomer and senator of Bologna, invited Cassini to work at his observatory in Pianzano.

It was during his time at this observatory that Cassini constructed his first astronomical instruments and conducted his first scientific observations. Over time, his interest in astrology diminished, and after his departure to France in , there are no records of his involvement in astrology.

Discovery of the great law.

Cassini's main scientific contributions were in the field of observational astronomy and geodesy. In , he became a professor of mathematics and astronomy at the University of Bologna, a position he held until He made numerous positional observations of the Sun using a meridian instrument and compiled new solar tables based on these observations, which were published in He also played a significant role in the establishment of the Paris meridian and the creation of the famous Cassini map of France.

Cassini made groundbreaking observations of the surfaces of planets, including Jupiter and Mars. By observing the movement of shadows from Jupiter's moons across the planet's disk and sketching the cloud patterns on its surface, he accurately determined Jupiter's rotation period. He also described the planet's banding system and measured its oblateness.

Cassini's observations of Mars allowed him to precisely determine its axial rotation period and describe its surface features. In , Cassini developed a theory and compiled tables of Jupiter's moon movements.
