I am having problems under standing Columbus's Voyage, I mean the direction and motives; if he was trying to Hemisphere, so the shortest distance would be to travel in North-westerly direction he seems to have done the opposite why? there is another thing Columbus should have had known the Circumference of the Earth and the land distance to the far Eastern Ocean so he mus have known the distance he had to travel. can some one explain this to me please!
