Donner party film research - Movie Review Example PatrickBreen left for US to live the life of his chosen religion which was catholic. Lansford Hastings saw US as a still undeveloped country which could be made very useful and profitable. Conversely, amajority of the people went to the US as an obvious destiny which was referred to as manifest destiny(The Donner Party). This destiny was a belief that American pilgrims were destined to develop the whole continent thus saw it as their justifiable land. This plus the idea of riches that awaited them with the discovery of gold them fuelled the desire to travel to California. George Donner and Jacob Donner were brothers who were already successful before they left for California. In fact the Donners are the mastermind of this journey and their opulence is portrayed in the type of wagons they hires for the family. They have three wagons each for their families.George Donner was motivated to travel by the gold discovery and free land in California. 2.Who was Alexis De Tocqueville? What was his reason for coming to America? Was De Tocquevilleâ€™s opening commentary in the film about the American people accurate at that time? Explain in some detail. Is De Tocquevilleâ€™s critique still relevant in American society today? Alexis De Tocqueville was a sociologist and political theorist of French origins. His reason for coming to America was to study the prisons of America. The study which led him to write his most acclaimed work â€˜democracy in Americaâ€™. Alexis opening commentary in the film was â€˜Americanâ€™s chase prosperity with great intensity until death eventually halts them in their tracksâ€™(The Tragic Story of the Donner Party). Alexis opening commentary in the film was very accurate at the time this is because the Donner party scrambled to get to California in order to get more free lands, riches and other wealth they had heard of before. Some people even were already successful like the Donner family but their greed led them to travel and most of

Petroleum extraction process - Term Paper Example
However, to start drilling the reservoir containing the sufficient amount of oil should be found. The researches on oilfield exploration started in 19th century. They were aimed on studying features of bedrocks. The main purpose was to find the rocks that were suitable rock as reservoir of oil (Speight 100). In the beginning of the 20th century surface rock with suitable characteristics were studied. New techniques developed in 1960s provided the possibility of exploration below the surface of earth (Speight 101).
New geophysical technologies are based on studying gravitational, magnetic, seismic, electric, electromagnetic and radioactive properties of the bedrocks. The methods are subdivided on techniques without depth control and techniques with depth control. The first group utilize spontaneous responses from local and distant sources that are controlled by the observer. The second group foresees introduction of energy (electric or seismic) into the ground, analyze and interpretation of transmissibility (Speight 101).
Gravitational methods are connected with studies of gravitational field which is affected by differences in density of geological bodies. Therefore, the gravimeter detects differences in density, and the detected variations permit to make a conclusion about the presence of rock formations (particularly oil). Magnetic methods are based on detection of the magnetic properties of the rocks. Detected difference provide the possibility to suggest the presence of desired materials. Seismic methods are based on creation artificial shock and detection the time necessary for the vibration impulse to get to the seismic detector. Depending on the obtained results, the conclusion about presence of oil can be made. Electric and radioactive methods are based on the measurement of conductivity and radioactivity (respectively) of the studied
