What were Christopher Columbus's acoomplishments....?

Question

and contributions of his voyage?

Answer 1

In 1492, Columbus sailed the ocean blue;
by 1493, half the Indians had V.D.

His voyages to America began a European effort at exploration and colonization of the continent. While history places great significance on his first voyage of 1492, he did not actually reach the mainland until his third voyage in 1498. (Wikipedia entry http://en.wikipedia.org/wiki/Christopher_Columbus)

Christopher Columbus neither proved the earth is round nor discovered the Americas.

Around 250 BC, the Greek mathematician Eratosthenes noticed that a post in the city of Alexandria, Egypt cast a shadow at noon on the summer solstice, the longest day of the year.

But at the same time in Syrene, a town due south from Alexandria, a similar post did not cast any shadow. Why was this?

Eratosthenes figured the sun must be shining its light at these two towns from different angles. The sun was directly above the post in Syrene, so the post did not cast any shadow.

But the sunlight was shining toward Alexandria at an angle. This was because the earth's surface was curved, Eratosthenes reasoned.

By knowing the distance between the two cities and by calculating the angle of the pole to the shadow, Eratosthenes was able to apply geometric theory to determine the size of the earth.

He figured out the diameter of the earth was 7,850 miles (12,633 kilometers). He was only off a little. The earth's actual diameter is about 7,926 miles (12,757 kilometers) at the equator.

By then, many Greeks knew for sure the world was shaped like a globe....

In 140 BC, a Greek known as Crates of Mallus built what may have been the first globe in history.

Native Americans were likely descendants of persons having emigrated from Asia. The most popular belief is that these people crossed a land bridge at what is now the Bering Strait.
