Galileo Galilei (1564-1642)
"
I think that in the discussion of natural problems we ought not to begin at the authority
of places of Scripture, but at sensible experiments and necessary demonstrations".
Galileo devised and used a telescope to discover the moons of Jupiter, craters of the
moon, moving spots on the sun, and the phases of Venus, all powerful evidence in favor of
the Copernican model of the Solar system. His Dialogues laid the groundwork of kinematics,
which led to Newton's dynamics. Threatened by the Inquisition in his old age, he publicly
renounced his belief that the Earth moves around the Sun, but according to legend,
whispered, "Nevertheless, it moves." |
