10 Lines on Galileo Galilei

Galileo Galilei was an Italian astronomer, scientist and philosopher, who played a significant role in the Scientific Revolution. Many important discoveries in the field of astronomy were made by him along with modifications in the telescope. Theory of Copernicus that the Earth is spherical in shape and it revolves round the Sun, was supported by Galileo Galilei.

He was also placed under house arrest for his anti religious views. His two new theories about kinetics and the strength of materials received admiration by the scientists of that time and became useful in the exploration of the space and universe.

Galileo was born in Pisa, Duchy of Florence, Italy in 1564 to a poor but noble family. His talents were recognized by his parents who made sacrifices for his education. At his father’s advice, Galileo studied medicine. But, in the University of Pisa, Galileo became attracted with a wide range of subjects. He also criticised many of Aristotle's teaching and theories which had dominated education for the past 2,000 years. Galileo made important discoveries about gravity, inertia and also worked on the pendulum clock and the laws of motion.

10 Lines on Galileo Galilei – Set 1

1) Galileo was born in Pisa, Duchy of Florence, Italy in 1564 to a poor but noble family.

2) He was enrolled in the University of Pisa to study medicines that he left in the middle in lack of money.

3) The most important of Galileo’s inventions is the telescope in 1609 which allowed the viewers to watch the events at distant places.

4) In 1610, Galileo was the first astronomer to discover the four moons of Jupiter later the moons were named “Galilean moons”.

5) Galileo’s telescope still survives, and is kept safely in a museum in Italy since his death.

6) It took 20 years to Galileo to study on the science of motion (kinematics), and mentioned the theory in his book called “The Little Balance.”

7) America has launched an unmanned spacecraft named “Galileo” in the honour of this great astronomer.

8) Galileo was the first scientist who told that the Milky Way Galaxy was a composition of millions of stars.

9) He used his telescope to study the moon and said that the moon is uneven, rough, and full of depressions and bulges.

10) Galileo was blind by the time he passed away on 8 January 1642, at the age of 77.


In the following new set of ten lines we have described below some scientific facts and discoveries of the famous scientist of 17th century Galileo Galilei. In these points you will find the scientific words and principals that will help the senior students for the better understanding of his work and findings. The avid readers may enjoy the lines and modify their knowledge. Hoping these special facts will prove important for you:

10 Lines on Galileo Galilei – Set 2

1) Once Galileo had to work as an art teacher in the Italian city of Florence for a short period of time.

2) The idea of the telescope first came into the mind of Galileo when he knew about the Spyglass that was invented by Dutch spectacles makers to observe ships.

3) He used the mechanism and modified spyglass with much higher magnification and build his first telescope in 1609.

4) He was the first who had observed the four moons of Jupiter- lo, Europa, Ganymede and Callisto and they are called Galilean moons.

5) Galileo’s concept of inertia is the foundation stone of Newton’s first law of motion that explains- an object in a state of motion possesses an 'inertia' that causes it to remain in that state of motion unless an external force acts on it.

6) America has launched an unmanned spacecraft to study Jupiter and its four moons and given the name “Galileo” in the memory of this great astronomer.

7) Galileo is also admired by the invention of the military compass, which was used as a calculating device between the 16th and 19th centuries.

8) Galileo’s theories and work was opposed by the church and he was kept under house arrest for eight years during the later portion of his life.

9) Galileo’s book, the "Dialogue Concerning the Two Chief World Systems" was banned by the church from 200 years and now it is lifted.

10) It is believed that Galileo's sight was lost because he used to observe the sun for long stretches of time using his different kind of telescope.

On reading the above lines we can say that Galileo's contribution in the field of science is a great source of knowledge for the young scientists. His inventions in the area of optics open the field for new discoveries in the Space and universe. Several institutions are working in many countries by his name. Still in universities researches are in progress.
