When was chemistry invented, so to speak? Well the answer is that no one really knows the exact date. It was thought to have been discovered around 3,000 BC, but at the time it was considered more of an art than a science. In any case, the history of Chemistry is long and has no end in sight, so rather than try to fit it into one article, let's discuss some of the key minds that made Chemistry what it is today. Let's start with Joseph Gay-Lussac; he was a French physicist born in 1778. In 1801 he carried out a study, which led to the publication of what is now called "Charles' Law". The reason the law is named after Charles and not Joseph is because Jacques Charles originally came up with this theory 15 years before Joseph Lussac, but did not publish it. Joseph was especially proud of what he calls his greatest achievement, which is now called Gay-Lussac's Law. This law states that “gases at constant temperature and pressure combine in simple numerical proportions by volume, and the resulting product or products – if gases – also have a simple proportion by volume to the volumes of the reactants.” The last noteworthy thing he was responsible for is his contribution to the discovery of the element Boron. Which today plays an important role in chemistry lessons around the world. The second chemist I would like to talk about is Jons Berzelius, born in 1779 in Sweden. This was the man who invented the technique of chemical formula notation. Which has played a big role in our classroom lately. Jons was a very successful electrochemist, rivaled by Humphry Davy, but it doesn't seem like much of a rivalry since Jons was much more systematic in carrying out his experiments. Another huge record... middle of paper... has been of great benefit to chemistry. Considering that X-rays will always be used in our society, and this just goes to show that in the future there may be more uses that have been opened up because of what this chemist has done. Which also ties into the topic of technology and how these chemists' techniques could advance our technology if used correctly. In the article I referenced many of the achievements of these chemists and how they present themselves in today's world. Just like Dmitri Mendeleev with the invention of the periodic table, which undoubtedly appears in every science lesson around the world. The history of chemistry is shown through many aspects such as technology and the progress of inventions that are not necessarily new technologies such as the periodic table. But in any case you start to see a progression that threw these chemists one by one as it goes along with the time period.
