Galileo was born in Pisa (then part of the Duchy of Florence) on 15 February 1564, [16] the first of six children of Vincenzo Galilei, a leading lutenist, composer, and music theorist, and Giulia Ammannati, the daughter of a prominent merchant, who had married two years earlier in 1562, when he was 42, and she was 24.
1610 – Galileo Galilei: discovered the Galilean moons of Jupiter; 1613 – Galileo Galilei: Inertia; 1621 – Willebrord Snellius: Snell's law; 1632 – Galileo Galilei: The Galilean principle (the laws of motion are the same in all inertial frames) 1660 – Blaise Pascal: Pascal's law; 1660 – Robert Hooke: Hooke's law; 1662 – Robert ...
Galileo Galilei as a scientist performed quantitative experiments addressing many topics. Using several different methods, Galileo was able to accurately measure time. Previously, most scientists had used distance to describe falling bodies, applying geometry, which had been used and trusted since Euclid. [12]

[127] 1619: Johannes Kepler: third law of planetary motion. 1620: Appearance of the first compound microscopes in Europe. 1628: Willebrord Snellius: the law of refraction also known as Snell's law. 1628: William Harvey: blood ...
Galileo Galilei, early proponent of the modern scientific worldview and method (1564–1642) The Italian mathematician, astronomer, and physicist Galileo Galilei (1564–1642) was a supporter of Copernicanism who made numerous astronomical discoveries, carried out empirical experiments and improved the telescope.
The Discourses and Mathematical Demonstrations Relating to Two New Sciences (Italian: Discorsi e dimostrazioni matematiche intorno a due nuove scienze pronounced [diˈskorsi e ddimostratˈtsjoːni mateˈmaːtike inˈtorno a dˈduːe ˈnwɔːve ʃˈʃɛntse]) published in 1638 was Galileo Galilei's final book and a scientific testament covering much of his work in physics over the preceding ...
1583 – Galileo Galilei deduces the period relationship of a pendulum from observations (according to later biographer). 1586 – Simon Stevin demonstrates that two objects of different mass accelerate at the same rate when dropped. [2] 1589 – Galileo Galilei describes a hydrostatic balance for measuring specific gravity.
[140] [141] [142] Giovanni Faber coined the name microscope for the compound microscope Galileo submitted to the Accademia dei Lincei in 1625 [143] (Galileo had called it the "occhiolino" or "little eye"). Microscopic anatomy and histology: pioneered by Marcello Malpighi in the 1660s.
