The Making of the English Working Class: A Radical Perspective

Chemistry4.03 KB

Thompson: A Marxist Historian

Thompson was a historian with a Marxist background whose interest in radical political works sets him apart from other authors we studied. He, like Hoggart, followed culturalism, a perspective that stresses human agency, or the active production of culture and not its passive consumption. His book The Making of the English Working Class really embodies the term, since in it he traces the development of the English working class between 1780 and 1832, more or less the time encompassed by the Industrial Revolution. The book can be seen as a rescue operation of the members (especially radicals) of the working class lost in a history led by the deaths of monarchs, statesmen, military leaders, and politicians. These...

From Ireland's gently rolling hills to Iceland's icy glaciers and fiery volcanoes, Northern Europe is a land of great variety. Because of this variety, the physical geography of Northern Europe changes greatly from one location to another.

Geology3.09 KB

Write the schedule of the main big bang events.

Before the Big Bang, according to scientists, the vastness of the observable universe, including all its matter and radiation, was compressed into a hot, dense mass. This point experienced a violent expansion, origin of time, space and all groupings of matter. This almost incomprehensible estate has been speculated that existed just a reaction of the first second of time. Massive blast allowed all known matter and energy of the universe, including space and time, to arise from some type of unknown energy. As the universe expands over time, the size increases, but temperature decreases and its density too. As time passed the material were getting cooler and began to form diverse types of atoms,
