going byebye essays The Protestant Reformation started in the 1500's when the Church started giving indulgences, or pardons for their sins, when someone gave money. The Catholic Church had always taught that when people die they cannot enter heaven before suffering some form of punishment for their sins in purgatory (a place between heaven and Hell). When a person was granted an indulgence, he was freed from some of his suffering in purgatory. In Germany a monk named Martin Luther wanted the Church to change many things it did. He didn't like the fact that they were selling indulgences. In 1517 Catholic fund-raisers began selling indulgences in Martin Luther's city of Wittenberg. In the same year Luther said that there was no basis in Christianity for the sale of indulgences and he drew up a list of objections to indulgences called the 95 Theses and nailed it to the Church door. The 95 Theses spread very quickly thanks to the printing press. Martin Luther believed that if men are sorry for their sins and have faith in God, they will be forgiven. He also believed that men do not win forgiveness by paying money. Many people in Germany agreed with Luther. Besides his beliefs the people had other Church practices they did not like. Martin Luther encouraged these discussions and not only attacked the pope but also criticized the German rulers. The Beginning of the Reformation Martin Luther was excommunicated, meaning no longer a member of the Catholic Church and could not receive any of its sacrements (baptism, conformation, marriage) by the pope. But Lutheranism, or Luther's ideas, spread. Many leaders of the German states agreed with Luther. More German leaders supported Martin Luther as his protests grew stronger. And thats when the Reformation began. Christians who did not accept the rules of the Roman Catholic Church became known as "Protestants." Eventually, Norway, Denmark, Sweden, Switzerland, England and other countries brok...

How John McAdam Changed Roads Forever

How John McAdam Changed Roads Forever John Loudon McAdam was a Scottish engineer who modernized the way we build roads. Early Life McAdam was born in Scotland in 1756 but moved  to New York in 1790 to make his fortune. Arriving at the dawn of the Revolutionary War, he began working in his uncle’s business and became a successful merchant and prize agent (in essence, a fence who takes a cut from selling off the spoils of war).   Returning to Scotland, he purchased his own estate and soon became involved in the maintenance and governance of Ayrshire, becoming a road trustee there. Builder of Roads At the time, roads were either dirt paths susceptible to rain and mud, or very expensive stone affairs that frequently broke down not long after whatever event precipitated their construction.   McAdam was convinced that massive stone slabs would not be needed to carry the weight of passing carriages, as long as the road was kept dry. McAdam came up with the idea of raising roadbeds to ensure adequate drainage. He then designed these roadbeds using broken stones laid in symmetrical, tight patterns and covered with small stones to create a hard surface. McAdam discovered that the best stone or gravel for road surfacing had to be broken or crushed, and then graded to a constant size of chippings. McAdams design, called MacAdam roads and then simply â€Å"macadam roads,† represented a revolutionary advancement in road construction at the time. The water-bound macadam roads were the forerunners of the tar- and bitumen-based binding that was to become tarmacadam. The word tarmacadam was shortened to the now-familiar name: tarmac. The first tarmac road to be laid was in Paris in 1854, a precursor to todays asphalt roads. By making roads both significantly cheaper and more durable, MacAdam triggered an explosion in municipal connective tissue, with roads sprawling out across the countryside. Fittingly for an inventor who made his fortune in the Revolutionary War- and whose life’s work united so many- one of the earliest macadam roads in America was used to bring together the negotiating parties for the surrender treaty at the end of the Civil War.  These reliable roads would be crucial in America once the automobile revolution began in the early 20th century.
