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.

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 ...
Galileo Galilei (1564–1642) crafted his own telescope and discovered that the Moon had craters, that Jupiter had moons, that the Sun had spots, and that Venus had phases like the Moon. Portrait by Justus Sustermans. Galileo Galilei was among the first to use a telescope to observe the sky, and after constructing a 20x refractor telescope. [83]
The Assayer (Italian: Il saggiatore) is a book by Galileo Galilei, published in Rome in October 1623. It is generally considered to be one of the pioneering works of the scientific method, first broaching the idea that the book of nature is to be read with mathematical tools rather than those of scholastic philosophy, as generally held at the time.
1643: Barometer: invented by Evangelista Torricelli, or possibly up to three years earlier by Gasparo Berti. [390] 1650: Vacuum pump: Invented by Otto von Guericke. [391] 1656: Pendulum clock: Invented by Christiaan Huygens. It was first conceptualized in 1637 by Galileo Galilei but he was unable to create a working model. [392]
