Galileo Galilei

Galileo Galilei was born February 15th of 1564 in Pisa, Italy and died on January 8th 1642 in Arcetri, Italy at age 77.

Galileo was the first of six children of Vincenzo Galilei and Giulia Ammannati. Galileo's beloved, elder daughter, Virginia was devoted to her father. She is buried with him in his tomb in the Basilica of Santa Croce, Florence.

In physical appearance, Galileo was around 5 ft 6 with a white complexion, a long, gray beard, and an oval-shaped face. Galileo's nationality was Italian.

Galileo was stubborn, curious, and an authentic scientist. His stubbornness led him to trouble with the church. He was very true to science and tried to understand the world through experiment and observation.

Galileo enrolled at the University of Pisa for a medical degree. Later, in 1589, he was appointed to the chair of mathematics in Pisa, and in 1592, he moved to the University of Padua where he taught geometry, mechanics, and astronomy until 1610.

Galileo was credited with the invention of the first thermometer in 1906. Galileo was the man who made the telescope famous, and his discoveries with the telescope convinced him that the Sun, was not the Earth, was the center of the solar system.

Above, is the model of the first thermometer invented by Galileo Galilei.

After Galileo's death, the church couldn't deny the truth in science. In 1758, it lifted the ban on most works supporting Copernican theory, and by 1835 dropped its opposition to heliocentrism altogether.

Galileo's contribution to our understanding of the Universe was significant not only in his discoveries, but in the methods he developed and the use of mathematics to prove them. He was named, "The Father of Modern Science."

In our world today, we still use the telescope similar to the one Galileo had created decades ago. We also still use a thermometer to for both weather and body temperature.

"We cannot teach people anything; we can only help them discover it within themselves." - Galileo Galilei, the Father of Modern Science.
