.....and chemistry born! (Part 2)

                 

                     This story represents a time span from ancient history to the present. In the ancient period, the chemistry was familiar with fewer people. Chemistry concerned with the substances of which matter is composed, the investigation of their properties & reactions, & the use of such reactions to form new substances; but many people of that period didn't know about this; many curious people wanted to know about chemistry and its work, they decided to investigate the chemistry & they did the same.

                Alchemy was an old name of chemistry. It was an ancient period. People of that period considered that chemistry works on different properties (colour, density, smell & so on), states (solid, liquid, gas) & reactions of matter or environmental substances. They started to learn more about these things. They started to learn philosophical theories that related to chemistry can probably be traced back to every ancient civilization. The common aspect in all these theories was the attempt to identify a small number of primary classical elements that make up all the various substances in nature. Substances like air, water & soil/earth, energy forms such as fire & light, & more abstract concepts such as thoughts, aether & heaven were common in ancient civilizations. Ancient Greek, Indian, Mayan & Chinese philosophies all considered air, water, earth & fire as primary elements.

                   Around the period 420 BCE, there was a Greek philosopher Empedocles who stated that all matter is made up of four elemental substances earth, fire, air & water, Aristotle was another Greek philosopher who also declared the same statement in 300 BCE, in addition, he said that these four elements are based on four properties those are hot, cold, dry & wet. In that period ancient Greek & India were curiously studying chemistry. An Indian philosopher Maharishi Kanada(around 6th-4th century BCE), the Greek philosopher Democritus were studying chemistry & they gave birth to atomism theory in that period. Maharishi Kanada, Democritus, Leucippus, Aristotle, Epicurus were the great ancient philosopher who was struggling to learn chemistry. There were many suits between their statements.      

                What was atomism theory? How did they study it?  You'll get answers to all these questions in the next part of ".....and chemistry born! ".
