In the 1700s, James Watt caused a revolution in transportation<em> by improving steam engine technology.</em>
He was a Scottish inventor and mechanical engineer. He made improvements on Thomas Newcomen's steam engine that was patented in 1698 and widely in use at the time of Watt's birth ( 1736).
It all started when Watt was given a model Newcomen engine to repair. He realized it was very inefficient and he began to find ways to improve its performance. He designed a separating condensing chamber for the engine to avoid huge losses of steam. He patented his improvements in 1769.
A unit of measurement of electrical and mechanical power -<em> the watt</em> - is named in his honor.
Both the American Revolution and French Revolution were the products of Enlightenment ideals that emphasized the idea of natural rights and equality. With such an ideological basis, it becomes clear when one sets out to compare the French Revolution and American Revolution that people felt the need to be free from oppressive or tyrannical rule of absolute monarchs and have the ability to live independent from such forces. The leadership in both countries at the time of their revolutions was certainly repressive, especially in terms of taxation. Both areas suffered social and economic hardships that led to the realization that something must be done to topple the hierarchy and put power back into the hands of the people.
While there are several similarities in these revolutions, there are also a few key differences. This comparison essay on the French and American Revolutions seeks to explore the parallels as well as the divisions that are present in both the American Revolution and the French Revolution. The political climate in France during its revolution was quite different than that in America simply because there was not a large war that had just ended in America (while in France the Seven Years War had nearly devastated the French monarchy’s coffers). Furthermore, although the lower and middle classes were generally the majority of the rebelling populace, there was far more upper class support for the revolution in France versus the participation of loyalists in America.
Answer:
The exchange introduced a wide range of new calorically rich staple crops to the Old World—namely potatoes, sweet potatoes, maize, and cassava. The primary benefit of the New World staples was that they could be grown in Old World climates that were unsuitable for the cultivation of Old World staples.
