Explanation:
On February 24, 1836, William Barret Travis, Commander of the Texian rebels in the former mission known as the Alamo, wrote a plea for help as they were surrounded by enemy forces under Mexican dictator Santa Anna. Addressed to “The People of Texas and All Americans in the world” and signed “Victory or Death,” this letter is known as one of the most stirring documents in American history.
Travis’ letter had an immense and immediate effect. Responding to the letter, 32 men arrived from Gonzales on March 1, 1836. Word of his letter spread quickly, first to New Orleans then onward to Boston and New York City. Yet with the Alamo located hundreds of miles from the U.S. border and a month from Washington, D.C., distance and terrain prevented most volunteers from arriving before the Alamo fell on March 6.
A fan of dramatic writing, Travis understood the power of words. He addressed his letter to “All Americans in the world” specifically to inflame their patriotic passions and rally them to his cause and that of Texas. In so doing, he transformed the Texas Revolution into an American fight for liberty against tyranny.
In Texas, many of the volunteers stirred by Travis’ letter formed the core of the army Sam Houston led to victory over Santa Anna on April 21, 1836. With his defeat, the Republic of Texas was born and a chain of events began that led to the Mexican War a decade later. U.S. victory in that war brought the American Southwest into the nation. Consequently, Travis’ letter shaped the destiny of America and the world.
Plastic is a word that originally meant “pliable and easily shaped.” It only recently became a name for a category of materials called polymers. The word polymer means “of many parts,” and polymers are made of long chains of molecules. Polymers abound in nature. Cellulose, the material that makes up the cell walls of plants, is a very common natural polymer.
Over the last century and a half humans have learned how to make synthetic polymers, sometimes using natural substances like cellulose, but more often using the plentiful carbon atoms provided by petroleum and other fossil fuels. Synthetic polymers are made up of long chains of atoms, arranged in repeating units, often much longer than those found in nature. It is the length of these chains, and the patterns in which they are arrayed, that make polymers strong, lightweight, and flexible. In other words, it’s what makes them so plastic.
These properties make synthetic polymers exceptionally useful, and since we learned how to create and manipulate them, polymers have become an essential part of our lives. Especially over the last 50 years plastics have saturated our world and changed the way that we live.
The First Synthetic Plastic
The first synthetic polymer was invented in 1869 by John Wesley Hyatt, who was inspired by a New York firm’s offer of $10,000 for anyone who could provide a substitute for ivory. The growing popularity of billiards had put a strain on the supply of natural ivory, obtained through the slaughter of wild elephants. By treating cellulose, derived from cotton fiber, with camphor, Hyatt discovered a plastic that could be crafted into a variety of shapes and made to imitate natural substances like tortoiseshell, horn, linen, and ivory.
This discovery was revolutionary. For the first time human manufacturing was not constrained by the limits of nature. Nature only supplied so much wood, metal, stone, bone, tusk, and horn. But now humans could create new materials. This development helped not only people but also the environment. Advertisements praised celluloid as the savior of the elephant and the tortoise. Plastics could protect the natural world from the destructive forces of human need.
The creation of new materials also helped free people from the social and economic constraints imposed by the scarcity of natural resources. Inexpensive celluloid made material wealth more widespread and obtainable.

did you know that they wanted Washington to become king? Washington was like "Bro we just got away from Britian and won our freedom from monarchy. We are not doing that. In order to prevent this from happening, or from this to be a dictatorship, how about we're only allowed to serve for two terms? four years each. How does that sound?"
