The first transcontinental rail passengers arrived at the Pacific Railroad's original western terminus at the Alameda Mole on September 6, 1869 where they transferred to the steamer Alameda for transport across the Bay to San Francisco.

When Galileo Galilei proved the Heliocentric Theory he was later condemned as a heretic by the Catholic Church.
George Washington Bush and another family, the Simmons, moved west on the Oregon Trail, but by the time they got there, a law was past that African Americans could not settle in the Oregon Territory, so instead they moved cross the Columbia River into land owned by both Great Britain and the United states, and the Bush's and five other families created a settlement there called "Bush Prairie."
Bush's experience as a multi-racial (Irish and African) person show the interdependence of people of different races on the western frontier, as well as the difficulties regarding racial prejudice.

The situation that resulted from the globalization is different cultures sharing their traditional food, traditions between them. Also nations share knowledge and technologies easier than ever. We can make faster trades between nations also. For example we can eat vietnamese food in Manhattan's downtown.
