Natural science is one of the branches of science. Understanding aspects of nature by means of logic, observation or experimentation, explaining them and producing hypothesis about them are the areas of natural science. Chemistry is one of the branches of natural science that discusses structure of matter, their nature and changes. For example, coal contains carbon. Chemistry discusses how the carbon atoms reside in coal and how these atoms react with oxygen in air when burnt and how they produce heat. All matters including animals and objects are its subject. Natural science has branches like physics, chemistry, botany, zoology, microbiology, astronomy, soil science etc. What is there in your food and how they are there is discussed in chemistry. Again, think of the new cycle you bought. After some days, the iron parts of the cycle started to get rust on them. Chemistry discusses that too. Chemistry started with the creation of this world. But it is probably the moment when the first man built a fire striking two stones that man started to have their control on chemistry. From the prehistoric age, humans have used chemistry when they refined metals, made earthen utensils burning soil, prepared medicines and perfumes taking extracts and juices from trees and plants. So far, we know that the first metal human beings used is gold. Besides, they have also used metals like copper, tin, silver etc.
Humans learned to melt copper and tin, mix them and cool the mixture into another hard alloy named bronze at around 3500 BC. Bronze was used to make quality weapons. These were used by the people to hunt animals, cultivate crops, cut fire wood etc. This alloy became an essential product of the then human race. Bronze contributed a lot to the progress of human civilization.
The ancient philosophers used to think a lot about structure of matters. The Greek philosopher Democritus declared in 380 BC that, a small particle will be available at a stage when we synthesize any metal. This particle is indivisible and he called it atom. Some Indian philosophers of the age also had similar views. But none of these ideas had a practical base. Aristotle opposed this idea. He along with another school of philosophers believed all matters are made of soil, fire, water and wind. That is why humans did not accept the idea of atom for quite a long time.
In the medieval age, some Arab Muslim philosophers tried to make gold out of cheaper materials like copper, tin and lead. They also tried to get an elixir which would lengthen the life of humans. Though they failed in their original attempts yet they wrote down their experiments. Basically, these were the earliest attempts of systematic study of chemistry or These medieval Arab experimentation with chemistry was called Alchemy and the philosophers were known as The term Alchemy comes from the Arabic word A1-Chimia which again takes its origin from Chemi or Kimi. The word chemistry comes from this chemi. Alchemist Jabir A1 Hiyan is the first scientist to hold chemical experiment in a laboratory. That is why he is sometimes called the father of chemistry. Jabir al Hiyan believed all matters composed of four components- soil, fire, water and wind. Therefore, although experimented, Jabir was not very clear about the mysteries of chemistry. Scientists including Antony Lavorsiere, Robert Boyle, Sir Francis Bacon and John Dalton are tie first school to start experimenting with chemistry the real spirit Of this science. Antony Lavorsiere is called the father of modern chemistry.
