The most important contribution to European expansion was the search for new trade routes. Christopher Columbus in 1492 accidentally stumbled across the Americas on his way to India in search of foreign goods and a new‚ quicker path to get to them. The Europeans already had trade routes‚ but each of them had a flaw. Either the route was too long‚ too costly‚ or too long. The main countries of their times sent different explorer’s to find new trade routes. Portuguese Prince Henry (the Navigator)

Linear Thermal Expansion The term thermal expansion refers to the increase in size of an object as that object is heated. With relatively few exceptions‚ all objects expand when they are heated and contract when they are cooled. Perhaps the most important exception to this rule is water. Water contracts as it cools from its boiling point to about 39.2°F (4°C). At that point‚ it begins to expand as it cools further to its freezing point. This unusual effect explains the fact that ice is less dense

Coefficient of Linear Expansion Introduction With few exceptions materials expand somewhat when heated through a temperature range that does not produce a change in phase (i.e. melting‚ freezing‚ boiling etc.). The added heat increases the average amplitude of vibration of the atoms in the material‚ which increases the average separation between the atoms. Although this effect is small‚ it is very important in any application that involves using different materials in an environment where they

Modern Human Expansion Archaeology 201 November 23‚ 11 Modern Human Expansion Modern human expansion from Africa began 70‚000-85‚000 thousand years ago‚ but recent discoveries have found that they could have exited as early as 125‚000 years ago. Many factors lead to the beginning of the African exodus of the modern human population. The most prominent factors involved with their rapid expansion are the drastic climate changes in that area.

“In 1899‚ two years before assuming the presidency of the United States‚ Theodore Roosevelt published an article entitled‚ “Expansion and Peace" in the popular weekly political magazine the Independent.

1. Nomadic expansion has affected history in many ways. When nomadic groups expand they take over different peoples sometimes even destroying empires‚ like in the case of Assyria and Harappa. Expansions have also called major movements in population. When an empire flourishes more people move to the empire than move away from it making it a center of population increase. They have also spread technology; especially things that help in warfare‚ established trade among empires‚ and helped get world

Portuguese and Spanish Slavery Thus when Portugal and Spain established the first American colonies‚ they first introduced Africans as a labor source in the New World. Both encountered difficulties turning the native American people into a slave labor force. The Spanish were more successful as they encountered the settled agraian societies of the Andes and central Mexico. The Spanish engaged in a debate concerning the humanity of the Native Americans. The Native Americans were in the end turned into
