Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion, and also worked in applied science and technology, describing the properties of the pendulum and "hydrostatic balances". He was one of the earliest developers of the thermoscope and the inventor of various military compasses. With an improved telescope he built, he observed the stars of the Milky Way, the phases of Venus, the four largest satellites of Jupiter, Saturn's rings, lunar craters, and sunspots. He also built an early microscope.
生平与生涯
Galileo's championing of Copernican heliocentrism was met with opposition from within the Catholic Church and from some astronomers. The matter was investigated by the Roman Inquisition in 1615, which concluded that his opinions contradicted accepted Biblical interpretations.
Galileo later defended his views in Dialogue Concerning the Two Chief World Systems (1632), which appeared to dispute and satirize Pope Urban VIII, thus alienating both the Pope and the Jesuits, who had both strongly supported Galileo until this point. He was tried by the Inquisition, found "vehemently suspect of heresy", and forced to recant. He spent the rest of his life under house arrest. During this time, he wrote Two New Sciences (1638), primarily concerning kinematics and the strength of materials.

遗产与影响
The influence of Galileo Galilei extends far beyond his own lifetime. He fundamentally shaped our understanding of the natural world, and his discoveries and theories remain foundational to this day.
Though he passed away in 1642, his ideas continue to be studied, debated, and built upon by scholars and practitioners worldwide.
