Chemistry has existed since the earth was created, a time when computers, televisions, or simple containers had not yet been invented. Chemistry has always existed, but it was not considered a science until modern chemistry was discovered. Modern chemistry has only been around for centuries, when author Robert Boyle published The Skeptical Chemist in 1661. Soon after Robert's publication, Antoine Lavoisier developed the law of conservation of mass, and that was the beginning of modern chemistry considered a science . After that, chemistry changed forever. Starting in the prehistoric era, chemistry was first used to explain religious things, such as known metals compared to celestial bodies. 1,330 years later Democritus stated that the atom is the simplest of all matter, a statement that was the first of its kind when it came to matter. One hundred and thirty years later, Aristotle declared the existence of the four elements, fire, water, air and earth. He also said that matter had four properties: hot, cold, dry and wet. All these things happened in the period between Prehistory and the beginning of the Christian era. Chemistry was considered black magic in this time period. Alchemy, which used scientific methods to turn base metals into gold, came into use soon after. The beginning of alchemy came when alchemists, using the influence of Aristotle, attempted to turn cheap metals into gold, something that was an unheard of idea at the time, and to do so they used something called the Philosopher's Stone. Pope John XXII soon after issued an order declaring that gold processing was prohibited, but this did not stop gold producers. Goldsmiths continued to try to create gold from simple, known metals, but they failed... middle of paper... television would have been blocked a lot if it weren't for the invention of these tubes . Soon I feel that the vacuum tube will lead to even bigger things, with even more innovations in the vacuum tube field, and I have a feeling that it will only get bigger from here on out. Chemistry is a huge subject, with a history that dates back all over the world. let's go back to BC, a time when the United States had not yet been thought of, and now one of the few things that have progressed so far from that time period, has been chemistry. From the thought that black magic and alchemy are real to today, where chemistry is huge with new discoveries every year, you can only begin to scratch the surface of the impact chemistry has had on our society. Chemistry is an ever-expanding subject, and I feel that at the moment we have covered very little of the mystery of chemistry.
