At the age of 22, Galileo published a book about a hydrostatic balance he had invented. In this way his name became known to other scientists. in 1589, aged just 25, he was awarded the Chair of Mathematics at the University of Pisa. Proposed the first theory of relativity: that the laws of physics are the same for all observers moving in a straight line at constant speed.

Showed that the set of perfect squares 1, 4, 9, 16, 25, 36, 49, 64, 81, 100… has as many members in it as the set of whole numbers 1, 2, 3, 4, 5, 6, 7, 8 9, 10… even though, at first sight, the set of whole numbers appears to contain more members. This demonstration became known as Galileo's Paradox.

The basis of Galileo's proof is that there must be as many whole numbers squared as there are whole numbers, because every whole number can be squared - so every whole number can be paired up with its square.

Galileo's troubles began in 1613 when he was 49 years old and published Letters on Sunspots.He also said he preferred the idea that the earth orbits the sun to the idea that the earth is the center of the universe: this was known as the Copernican view after Nicholas Copernicus proposed a heliocentric or sun-centered Solar System in 1543.
