Detroit remains one of the most racially segregated cities in the United States. From the 1940s to the 1970s a second wave of Blacks moved to Detroit to escape Jim Crow laws in the south and find jobs. However, they soon found themselves excluded from white areas of the citythrough violence, laws, and economic discrimination (e.g., redlining). White residents attacked black homes: breaking windows, starting fires, and exploding bombs. The pattern of segregation was later magnified by white migration to the suburbs. One of the implications of racial segregation, which correlates with class segregation, may be overall worse health for some populations.
What is an example of economic discrimination?
redlining

Bush's margin of victory in the popular vote was the smallest ever for a reelected incumbent president, but marked the first time since his father's victory 16 years prior that a candidate won a majority of the popular vote. The electoral map closely resembled that of 2000, with only three states changing sides: New Mexico and Iowa voted Republican in 2004 after having voted Democratic in 2000, while New Hampshire voted Democratic in 2004 after previously voting Republican. In the Electoral College, Bush received 286 votes to Kerry's 252.
How many States renounced their preferred political party?
three

Muslim engineers in the Islamic world made a number of innovative industrial uses of hydropower, and early industrial uses of tidal power and wind power, fossil fuels such as petroleum, and early large factory complexes (tiraz in Arabic). The industrial uses of watermills in the Islamic world date back to the 7th century, while horizontal-wheeled and vertical-wheeled water mills were both in widespread use since at least the 9th century. A variety of industrial mills were being employed in the Islamic world, including early fulling mills, gristmills, hullers, sawmills, ship mills, stamp mills, steel mills, sugar mills, tide mills and windmills. By the 11th century, every province throughout the Islamic world had these industrial mills in operation, from al-Andalus and North Africa to the Middle East and Central Asia. Muslim engineers also invented crankshafts and water turbines, employed gears in mills and water-raising machines, and pioneered the use of dams as a source of water power, used to provide additional power to watermills and water-raising machines. Such advances made it possible for industrial tasks that were previously driven by manual labour in ancient times to be mechanized and driven by machinery instead in the medieval Islamic world. The transfer of these technologies to medieval Europe had an influence on the Industrial Revolution.
In what century had mills such as gristmills and sawmills dominate the Islamic world?
11th century
