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.
The Treaty of Guadalupe hidalgo was established in the war between the United States and Mexico. It was signed on February 2, 1848 and has been treated in the ancient past that is still in effect between the United States and Mexico. As a result of the treaty, the United States acquired more than one million two hundred thousand square kilometers of valuable territory and emerged as a world power at the end of the nineteenth century.
In the 1850s, reformers also came to power in Mexico and promised to strengthen the country's political system so as not to be more victims of US aggression. The reform of Benito Juarez ( President at the time) was the beginning of a process of political and economic modernization that continues to the present in Mexico.
