who is famously known for having discovered that the world was round?

you are rght about aristotle as it was Pythagoras (you know the theorem) 570 BC who hypothesised the curvature of the earth and the heavenly bodies,later the most notable writers on the positioning and behaviour of the planets were copernicus, gallaleio, kepler and newton

Hubble discovered expansion...sort of. He proposed it as a theory but it was a colleague who did the math and proved it. I can't remember the colleague's name.

The use of grid lines on maps (latitude and longitude) was first suggested by the Greek astronomer Hipparcus about 300 years before Christ. He was the first who devised a method for fixing the location of places on earth by observation of the the sun, moon and stars. He worked out the mathematics of spherical trigonometry, which allowed the results of these observations to be plotted on an earth which he knew already to be a sphere.\n\nLatitude can be found easily by measuring the height of the sun at noon. The measurement of longitude is not so simple as you need an accurate clock.

Copernicus was a Polish astronomer and mathematician who was a proponent of the view of an Earth in daily motion about its axis and in yearly motion around a stationary sun. This theory profoundly altered later workers' view of the universe, but was rejected by the Catholic church.

columbus sailed west to the indies instead of going around africa because he thought it would be faster. most people those days believed the world was flat, but columbus thought the world was round. he went west, but ended up in north america, but he didn't know that. he called the people he saw there indians because he believed he was in the indies.

Isaac Newton. It would give him a big scare, considering he is most remembered for his laws of gravity.\nOh, and Christopher Columbus........."OMG!    It is flat!!!!"

Sir Isaac Newton, PRS, \n\n\n(4 January 1643 – 31 March 1727) [OS: 25 December 1642 – 20 March 1727] was an English physicist, mathematician, astronomer, alchemist, inventor, and natural philosopher who is generally regarded as one of the most influential scientists in history.\n\nNewton wrote the Philosophiae Naturalis Principia Mathematica wherein he described universal gravitation and the three laws of motion, laying the groundwork for classical mechanics. By deriving Kepler's laws of planetary motion from this system, he was the first to show that the motion of bodies on Earth and of celestial bodies are governed by the same set of natural laws. The unifying and deterministic power of his laws was integral to the scientific revolution and the advancement of heliocentrism.\n\nAmong other scientific discoveries, Newton realized that the spectrum of colours observed when white light passes through a prism is inherent in the white light and not added by the prism (as Roger Bacon had claimed in the 13th century), and notably argued that light is composed of particles. He also developed a law of cooling, describing the rate of cooling of objects when exposed to air. He enunciated the principles of conservation of momentum and angular momentum. Finally, he studied the speed of sound in air, and voiced a theory of the origin of stars.\n\nAmong Westerners, Newton played a major role in the history of calculus, sharing credit with Gottfried Leibniz. He also made contributions to other areas of mathematics, having derived the binomial theorem in its entirety. The mathematician and mathematical physicist Joseph Louis Lagrange (1736–1813), said that "Newton was the greatest genius that ever existed and the most fortunate, for we cannot find more than once a system of the world to establish

http://www.aquinas-multimedia.com/stjoseph/galileo.html\n\nMy guess was Galileo and I was right.  Here, look.\n\nBut according to a book I have, the greeks noticed it first.  It was Galileo that proposed the theory to the world.

Carl Friedrich Gauss (30 April 1777 – 23 February 1855) was a German mathematician and scientist of profound genius who contributed significantly to many fields, including number theory, analysis, differential geometry, geodesy, magnetism, astronomy and optics. Sometimes known as "the prince of mathematicians", Gauss had a remarkable influence in many fields of mathematics and science and is ranked beside Euler, Newton and Archimedes as one of history's greatest mathematicians.

I'm going out on a limb here, but I would say round.  The reason I say round is this.  Way back when, everybody thought the earth was flat, until someone sailed around the world.  What I don't get is the fact we can look up at the sun & moon, and it's plain to see they are round.  Why in the world would those people ever thought the earth was flat, I'll never know.  We are like fish in a bowl, we can see out but can't live out there.  As of now it is impossible for us to ever go that far out of the bowl without it killing us.  I don't think we will ever know the answer to that question, at least not in our lifetime.  Think about it, we can see into the past, and see things that has taken place millions of years ago.  Can we somehow see the other direction, and look into the future?  Maybe!  I too am fasinated by the universe, and wish I had answers to these questions, but since we are so tiny when compared to the universe, I wonder if we are not just a molicule of some giant living thing thats waiting to crawl off.  \nHave Fun.  Good Luck!!!

Columbus was challenged by the Spanish government, specifically the Queen, to disprove the commonly accepted  notion that the world was flat.  Conceptually, the formulation of his proof that the world was indeed "round" (spherical, or possible cylindrical - it's not specified in history texts what "round" meant to Columbus) was that if he could set some starting point and then sail around the world in a constant direction, should he return to his starting point then his theory would be proved.\n\nHe ended up in the Indies, which has ever since been named the "West Indies", but thought he was elsewhere.  As far as Columbus was concerned, he was sure that he had found some one of the outermost islands of Cipango or Japan. So he dropped his anchors, ordered out his rowboat, and prepared to take possession of the land in the name of the queen of Spain, who had helped him in his enterprise.\n\nOf course, he wasn't in Japan or Cipango...if you want a full text detail of the story, follow the link in references...this was the short version.\n\nI hope this helps you!!

Not sure who was the 'first' but the Egyptian Ptolemy left records that show he knew the Earth was a sphere.  He even calculated its circumference fairly accurately.\n\nWhere he was incorrect, of course, was proposing a geocentric view of the universe with the Earth in the middle and fairly complicated system of orbits to describe the movement of the various visible astronomical bodies.  It wouldn't be until Copernicus over a thousand years later, until this particular view was corrected.

It was discovered by Antonio Ingognito, in 1983. He had a good idea it would be where it was because his Lonely Planet book said so. Other people had discovered it before but they weren't explorers.

So Johann Kepler was a German astronomer, living between 1571-1630. He was the one who introduced the three laws of planetary motion. He worked and studied about the (elliptical) oval orbit, planets, and eclipse. He rivaled against the old beliefs on how the heavenly bodies moved in perfect circles...Well, he was one of those who questioned the church's beliefs an teachings. He thought of new ideas, observed things, and experiemented. The church/pope/Catholic and Protestants went against him, too. But those who began to think out of the box probably admired him or something.

Ancient civilizations knew this. Observations of lunar eclipses, plus the fact that the horizon is at equal distances no matter what direction we look made this pretty obvious. The earliest were probably the Assyrians or Babylonians, who developed the first coherent astronomical systems (claims by people that the natives of India were first notwithstanding)\n\nThe issue was not the shape of the earth, but its size, and its place in the scheme of things (at the center or off to the side.) It took thousands of years to displace the earth conceptually from the center of creation to a planet orbiting a star, which was then displaced from the center of the universe to a position in an outlying arm of our galaxy, which itself was displaced from being the entire universe to being the largest galaxy and at the center of the universe to being just another galaxy among billions. So we're just a bunch of hicks from the sticks.

this is going to require some research...but ptolemy actually came up with the idea that the earth revolves around the sun..he was greek...
