Answer: Paul isn't looking at a map, he's looking at a flattened version of an Atlas. Great Britain is in the middle of it because of the lines of longitude and latitude - Greenwich is at 0 degrees. Everything else is worked out from there. It's called the Mercator Map system.

Answer: It's not that the US is in the top left, it's that Great Britain is in the middle. You've just seen British maps and nothing else. Look at a Russian map and see where the countries are positioned.
