technology fire history prehistory
The invention of using fireplace was one of many first technological advances.

Instinctively, for the reason that starting of historical past , folks sought to develop know-how ( strategies  to enhance their  high quality of life ). The discoveries that man has made over time have formed the world as it's recognized right this moment, due to this fact, know-how has existed for the reason that starting of the species, though it has not been known as as such till the eighteenth century .

Formally talking, know-how has its origin when approach (initially empirical) started to be linked to  science  and on this approach manufacturing strategies are structured.

All through the totally different intervals of humanity there have been discoveries which have modified the best way through which the human being pertains to himself and the surroundings that surrounds him:

  • Stone Age ( Paleolithic , Mesolithic and Neolithic). It was characterised by means of stone for the manufacture of utensils and the event of agriculture with rudimentary instruments for managing the land. The invention of fireplace was one of many first applied sciences that supplied notable advantages to the human being.
  • Metallic Age. It was characterised by the event of agriculture , animal domestication and the transition from nomadism to sedentary way of life. The smelting of copper , bronze and iron developed. The Egyptian civilization is credited with the invention of papyrus and pottery; the Romans developed subtle agriculture, improved the know-how of working with iron, and developed civil and army engineering; Chinese language civilization is credited with the invention of paper, the iron plough, the compass, the propeller, the crossbow, and gunpowder .
  • Center Ages . The looks of the trendy printing press was one of the necessary milestones inside this era.
  • Industrial Revolution . It was a interval of social, financial, technological and cultural transformations characterised by the event of anurban and industrialized economic system . Probably the most distinguished innovations of this time was the steam engine . In the course of the nineteenth century, the telegraph, the sunshine bulb, the phone, and the car arose.
  • Twentieth century. There was an amazing technological improvement with discoveries such because the airplane, radio, tv , the laptop, in addition to necessary advances in nuclear know-how, know-how utilized to medication and house know-how. Inside this century there was the Info and Telecommunication Revolution or the Info Age (1985-2000).
  • XXI century. Technological progress (additionally known as the scientific-technological revolution or the intelligence revolution) advanced quickly. Expertise and communications rework business. New applied sciences are those who emerge after  World Warfare II. Its speedy progress and insertion into society introduced necessary penalties. The risk is basically provided that the human being is ready to management and dominate them.
