• Galileo Galilei Biography, Career, Personal Life

    Galileo Galilei was an Italian scientist. He was known for astronomer, physicist, and engineer. Galileo was born in Pisa, Italy, on 15 February 1564. He is the first of six children of Vincenzo Galilei. His father was a famous lutenist, composer, and music theorist. His mother Giulia di Cosimo Ammannati.

    • Name: Galileo Galilei
    • Birth: 15 February 1564
    • Birth Place: Pisa, Duchy of Florence, Italy
    • Education: University of Pisa 1580–1585 (no degree)
    • Death: 8 January 1642 Arcetri, Grand Duchy of Tuscany

    Galileo has been called the "father of observational astronomy", the "father of modern physics", the "father of the scientific method",  and the "father of modern science" His most notable contributions are the improvement of the telescope, which has played a major role in the progress of astronomy, the many astronomical observations of various kinds, the first and second sources of Newton's motion, and an important observation for Copernicus's theory. According to scientist Stephen Hawking, no one has contributed more than Galileo to such a huge advance in natural science in the modern age. He also the observation of the four largest satellites of Jupiter, the observation of Saturn's rings, and the analysis of sunspots.

    Galileo made a number of contributions to what is now known as engineering, as distinct from pure physics. Between 1595 and 1598, Galileo devised and improved a geometric and military compass suitable for use by gunners and surveyors. Galileo plays a pioneering role in the science of quantitative measurement. His measurements were passed in mathematical precision. At the same time, William Gilbert did some quantitative studies on magnetism and electricity.

    Galileo's discoveries have played a major role in ending Aristotelian ideas. He also Discovers the cause of the scandal of the moon. The discovery of Jupiter's satellite with the telescope is one of the most important discoveries of Galileo's first phase. He spent four consecutive nights observing Jupiter and found four satellites in Jupiter.


    Galileo's education began at a very young age. After general education, he was admitted to the University of Pisa, but due to financial turmoil, he had to stop his studies there. Nevertheless, in 1589 Galileo received a position for teaching at the University of Pisa and began teaching mathematics there. According to most experts, he was the most talented of the siblings.


    During his career as a professor, he taught in the faculty of geometry, mechanics, and astronomy until 1620. In 1612, Galileo went to Rome and joined the Accademia dei Lincei. There, he mainly monitored the solar scandal. In 1609 the telescope was invented, Discover the cause of the scandal of the moon, in 1610 the cause of the scandal of the moon was discovered. Most of the time he spent his time in various types of research and innovation.

    Personal Life

    Galileo and Marina Gamba gave birth to three children, but they were not married. The fact that Galileo was a devoted Roman Catholic seems to be unrealistic, given his prevailing adultery. They had two daughters (Virginia and Livia) and a son (Vicencio). To raise an unmarried child, their two daughters were sent to San Mateo Church in Arcetri at an early age.

    Honor and awards

    Galileo could not get any awards in his life but some written works are given him honor, like as-

    • The Little Balance in 1586,
    • On Motion in 1590,
    • The Operations of the Geometrical and Military Compass in1606,
    • The Starry Messenger in 1610,
    • Discourse on Floating Bodies in 1612,
    • History and Demonstration Concerning Sunspots in1613,
    • "Letter to the Grand Duchess Christina" (1615; published in 1636),
    • "Discourse on the Tides" in 1616,
    •  Discourse on the Comets in 1619,
    • The Assayer in 1623,
    • In 1632, Dialogue Concerning the Two Chief World Systems


    Galileo died on 8 January 1677. He died of suffering fever and heart palpitations. At this time his age was 77. His contribution will be remembered in the history of science.
