History
Great inventions started with the advent of human life on planet earth. Man’s curiosity and necessity led him to new discoveries since the Stone Age. Like the discovery of fire by an early man through striking of stones against each other. Man’s curiosity gave way to knowledge that kept getting more refined and more evidence based as the time grew. The history of chemistry traces its origin to the prehistoric times when some known metals were listed down during King Hammurabi’s reign over Babylon; followed by the discovery made by Democritus in 430 BC on the existence of matter in the form of particles which he called “atomos”.
Aristotle in 300 BC proclaimed that there existed only four elements: fire, air, earth and water and that these elements were characterized by four properties: hot, cold, dry and wet. Following Aristotle’s ideas, were people who then made attempts to find a method that could convert cheaper metals into gold that in turn gave birth to the protoscience called alchemy. Later in 1661 Robert Boyle made the distinction between chemistry and alchemy in his work The Sceptical Chymist. Chemistry developed as a complete science with Antonie Lavoisier’s work on the laws of Conservation of mass.
