Giulia Ammannati. Michelagnolo Galilei, Livia Galilei, Bened Galilei, Giulia
Galilei, and Virginia Galilei. Maria Celeste was his wife, and they had three
children. Virginia, Livia, and Vincenzo. Galileo was classified as an
astronomer, mathematician, philosopher, rebel scientist, and a physicist. He
was diagnosed with dyslexia.

            As
a child he attended Monastery school, and attended the University of Pisa. When
he went off to college, his father wanted him to study medicine, but Galileo
wanted to become a priest. When going through college is when he found a talent
for mathematics. Two incidents made him think about continuing in the physician
career field. The first incident, he was watching a chandelier. He realized
that it took the chandelier the same time to return to the first position.

Galileo attended a geometry lecture as his second incident. This is when he
decided to begin studying mathematics and natural philosophy. He ran into
financial problems and was forced to drop out of college in 1585. Unfortunately
he had to leave before he got his degree.

            After
dropping out of college he had to support himself, so he got a job at Accademia
Delle Arti de Disegno. While working her became interested in Renaissance
artists. Galileo was then promoted to the chair of mathematics at the
University of Pisa. While he was serving he conducted an experiment where he
dropped different items of different weights off the Leaning Tower’s. This
experiment led him to rule Aristotle’s idea false. His contract of the chairperson
was not renewed, but he was elected to the University of Padua chair of
mathematics. He served as the chair of mathematics for eighteen years.

            While
at Padua, he began to teach geometry, mechanics and astronomy. Unfortunately at
this time his father passed away, and he needed to support the family. He
didn’t feel like he was making enough money so he began to private teach also.

Little did he know that when he presented his new telescope to Nenetran Senate
that he would be so impressed and would double his salary. He built the
telescope in 1609, but made improvements to it that led to the impressment.

            The
telescope was a very good invention that he made. The telescope led him to many
discoveries. He was the first person to see that the moon’s surface was rocky
and uneven instead of smooth. Then, in 1610 he discovered that there were more
stars in space then the ones visible to the human eye. Due to this discovery,
wrote a book called, “The Starry Messenger.” Again in 1610 he discovered
Jupiter’s moons revolving around it. He then proved Aristotle wrong again.

Galileo found that the sun was not perfect, and that there were sunspots that
appeared on the sun. Following this discovery he wrote a book called, “History
and Demonstrations Concerning Sunspots and their Properties.” His last
important discovery was discovering why objects float. Once again he proved
Aristotle wrong. Aristotle believed that the reason an object floats is because
of their flat surface, but Galileo found out that it was all dependent on the
weight of the object.

            Galileo
Galilei died on January 8, 1642 at the age of 77. Before his death he wrote one
last book called “Two New Sciences.” It was published in 1638. The cause of his
death was a high fever and heart palpitations. Galileo was an outstanding scientist.

The things that was named after him include; Galilean Moons of Jupiter, the
Galileo Spacecraft, Asteroid 697 Galilea, Galileo Global Satellite Navigation
System, and Galiliean Transformation. Many novels, plays, and movie are about
his scientific life. I believe Galileo laid a foundation that the scientists can
now build on.
