The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others.
Galileo Galilei (1564â1642) has always played a key role in any history of science and, in many histories of philosophy, he is a, if not the, central figure of the scientific revolution of the 17 th Century.t was during his Paduan period that Galileo worked out much of his mechanics and began his work with the telescope. In 1610 he published The Starry Messenger, and soon after accepted a position as Mathematician and Philosopher to the Grand Duke of Tuscany (and a non-teaching professorship at Pisa).
Using the new technology of the telescope, Galileo discovered the moons of Jupiter: Io, Europa, Calisto, and Ganymede, thus proving that not all things orbit around the Earth, lending great support to the Copernican model of the heliocentric system.e was an Italian scientist of the 17th century. He did not prove  the heliocentric theory. But everyone accepts the heliocentric  principle now, after it was proved right; â¦ but that happened long  after Galileo's time, after new scientific discoveries in the  latter half of the 1600s.
