In 1914, English cartographer John G. Bartholomew created an isochronic map, a map that shows all points that are accessible in the same amount of time. Ships and railroads were the fastest modes of travel then, but relative to the planes, cars, and highways that have developed in the last century, they were extremely time consuming. In only a century, transportation among other things has developed to bring down 40 days of travel time to only a day and a half.
