What invention or discoveries, other than the Scientific Method, is Galileo Galilei well known for?

Answer 1

He is best known for hating his parents. I mean, it would be bad enough having the surname 'Galilei', but his Mum & Dad must have been truly twisted b.uggers to land him with Galileo as a first name too. Could they not have just stuck to 'Bob'? Personally, I would have shot the sons of b.itches, myself.

Answer 2

Aside from vast improvements to the telescope, he discovered the four largest Jovian moons (Jovian means 'belonging to Jupiter'). He found Io, Europa and Callisto in one night, and found Ganymede four days later. He also worked out that they orbited the planet, which was quite controversial, since at the time it was believed that Earth was the centre of the universe. So discovering orbiting things were... troubling.

He was also the first to observe that Venus had phases like the moon, which helped contribute to the heliocentric (centred around the sun) theory.

He was also one of the first to observe sunspots, and was the first to observe mountains and craters on the moon - Aristotle had believed the moon was completely smooth, Galilei saw that it was just as textured as Earth.

Finally, he discovered that the Milky Way was densely packed stars, so dense it appeared cloud-like, and not something like a nebula.

Oh! And he was one of the first to see Neptune, but didn't realise it was a planet - he attributed it as a weak star. Galileo Galilei was an amazing scientist.

Answer 3

Galileo also neither invented nor discovered the Scientific Method. He put it to effective use, and certainly helped promote it, but it already existed before he started doing his important work.

Credit for developing the Scientific Method generally goes to three men. Critical advances in the method were made first by AlHazen, muslim scholar in 1000 AD, followed by Europeans Francis Bacon in 1590 and Rene Descartes in 1637.

It was Descarte who coined the term.


Galileo's work mostly took place between that of Bacon and Descartes.

Answer 4

galileo did NOT invent the telescope!

that honour belongs to hans lippershey of holland, in 1608.

he was, however the first to USE a telescope and in doing so observational astronomy was born.

Answer 5

The 4 largest moons of Jupiter, an astonomical telescope (ie refractor)

Answer 6

Putting two lenses together to invent the telescope.

Answer 7

That the earth revolves around the sun.

Answer 8

The refracting telescope.

Note: that info is common knowledge, so now you know, too!
