Chemistry a kind of sciencethat can be clearly attributed to the humanitarian or technical. With formulas and expressions, it includes indefinite items, even philosophical. Studying chemistry? Who and why invented this science, and why children continue to pass it in schools?
There are several versions of the origin of the name. Some believe that it is associated with the concept of «black» in the Arabic language, which later became the description of the land of topsoil. Others are turning to the ancient Greek language provides three transfer. Perhaps the «chemistry» comes from «juice» or «alloy» and there is a translation of «mixing».
It is not excluded that all of these options, one way or another, correct. This science is multifaceted and therefore unlikely to stay on any one translation. Interestingly, she is something of a cross between biology and the humanitarian sphere, and physics, that refers to the exact.
She is one of the areas of natural science, which focuses on the substances. Chemistry studies their composition and structure, considering the current properties and their possible changes. Probably all from school remember complex chemical reactions and the many laws that had to learn.
Any substance is composed of atoms, which form, with the chemical bonds of the molecule. In this respect, the answer to the question what studies the science of chemistry, is given as follows:
- It concentrates on the problems listed above at atomic-molecular level;
- Science considers the elements and their compounds.
It would seem, how little studying chemistry! However, if we recall the fact that from the elements is absolutely everything, the richness of this science is simply amazing.
History of chemistry
One can hardly imagine life without this science. It appeared around the same time arose the first person. Chemicals always had a place in life, to take at least the process of extraction of fire or tanning hides. Even simple cooking is also a kind of chemical process.
Over time, accumulated knowledge and perfected. In the end, humanity began to create dyes, drugs and poisons. First of all, based on natural processes, like fermentation and putrefaction, but gradually began to use more complex methods. People learned to make alloys, to carry out redox reactions, impossible in the environment.
Many areas that today are perceived as something quite ordinary, appeared before our era. For example, the beginnings of cosmetics, perfumes and primitive metallurgy appeared for a long time – and it’s all thanks to chemistry. It is interesting that glass, which produced 4 thousand years before our era, is virtually indistinguishable from modern.
Although today anyone can own experience to know that studying chemistry, before it was a real privilege. As a rule, the chemical formula was posticalis (and kept secret) by priests and shamans.
The secrecy and mystery gave chemistry a mystical aura. Over time, when science was able to spread across different countries in Europe took over from the Arabs the name of «alchemy». They borrowed the term from srednerusskogo language, where it meant «fluid».
Alchemy was seen as a combination of art and chemistry, but, in fact, its roots lie in the esoteric sphere. Anyway, first, science has been used in Eastern countries for production of mercury or phosphorus, and over time, and alkalis. Approximately from the middle Ages to alchemy added a mystical component, based on the intricacies of the philosophy of the period.
Most people, alchemy is known for attempting transmutation designed to turn any substance into gold. Since ancient times, this material has become the universal equivalent of goods, and to him was extremely difficult. Such attempts continued until the fourteenth century.
Although to get gold out of nothing and failed, the labour of the alchemists helped to create other materials, and also master numerous methods of treatment. All of this was a significant contribution to gradually formed the science of chemistry.
