On this day in 1633, Italian philosopher, astronomer and mathematician
Galileo Galilei arrives in Rometo face charges of heresy for advocating
Copernican theory, which holds that the Earth revolves around the Sun.
Galileo officially faced the Roman Inquisition in April of that same
year and agreed to plead guilty in exchange for a lighter sentence. Put
under house arrest indefinitely by Pope Urban VIII, Galileo spent the
rest of his days at his villa in Arcetri, near Florence, before dying on
January 8, 1642.

Galileo, the son of a musician, was born February 15, 1564, in Pisa,
Italy. He entered the University of Pisa planning to study medicine, but
shifted his focus to philosophy and mathematics. In 1589, he became a
professor at Pisa for several years, during which time he demonstrated
that the speed of a falling object is not proportional to its weight, as
Aristotle had believed. According to some reports, Galileo conducted his
research by dropping objects of different weights from the Leaning Tower
of Pisa. From 1592 to 1630, Galileo was a math professor at the
University of Padua, where he developed a telescope that enabled him to
observe lunar mountains and craters, the four largest satellites of
Jupiter and the phases of Jupiter. He also discovered that the Milky Way
was made up of stars. Following the publication of his research in 1610,
Galileo gained acclaim and was appointed court mathematician at

Galileo’s research led him to become an advocate of the work of the
Polish astronomer Nicolaus Copernicus (1473-1573). However, the
Copernican theory of a sun-centered solar system conflicted with the
teachings of the powerful Roman Catholic Church, which essentially ruled
Italy at the time. Church teachings contended that Earth, not the sun,
was at the center of the universe. In 1633, Galileo was brought before
the Roman Inquisition, a judicial system established by the papacy in
1542 to regulate church doctrine. This included the banning of books
that conflicted with church teachings. The Roman Inquisition had its
roots in the Inquisition of the Middle Ages, the purpose of which was to
seek out and prosecute heretics, considered enemies of the state.

Today, Galileo is recognized for making important contributions to the
study of motion and astronomy. His work influenced later scientists such
as the English mathematician and physicist Sir Isaac Newton, who
developed the law of universal gravitation. In 1992, the Vatican
formally acknowledged its mistake in condemning Galileo.
