To invent is to create something new and something that did not exist before. An invention can be an idea, a principle (such as democracy), a poem, a dance or a piece of music. Technology is the practical application of our understanding of the world to achieve the things we need or want to do. Technology goes beyond “things” such as computers or bicycles it includes techniques and processes such as the alphabet, numerical systems and extraction of metals form their ores.

Science is our way of unraveling the laws of nature through theory and experiment. Science and technology are interdependent. The internal combustion engine, for example could not have been invented without a scientific understanding of thermodynamics and the chemistry of combustion. Conversely, inventions such as the microscope, the radio telescope and the computer have greatly aided scientific investigation. idea for invention

The Ancient World stone tools are widely accepted as the first human invention, made and used by our hominid ancestors around 2.5millions years ago. The inventions of the early Stone Age (The Palaeolithic) controlled fire, clothing, the sharp blade and the spear a well as stone tools are perhaps the most important inventions of all time. Without these technologies humankind might never have moved from hunting and gathering to a more settled lifestyle. It is no coincidence that the rate of technological dramatically once people were more settled. The first great civilization arose around 7,000 years ago in Mesopotamia (in what is now Iraq). The wheel and axle, another candidate for the world’s most important invention, originated in ancient Mesopotamia as did glass and irrigation.

From Rome to Revolution takes us from the Romans to the start of the start of the Industrial Age. In the first hundred years C.F., most technological innovation took place in the Indus Valley and is ancient China. Many of the important inventions created in the Indus Valley remained unknown to the rest of the world but people did learn of the Chinese inventions-in particular, the “four great inventions”: gunpowder, paper, the compass and painting. Chinese civilization remained stable and continued to innovate.idea for invention

The Islamic Empire emerged in the eight century and Islamic scholars passed on and added much to the work of the ancient Greek thinkers which would have otherwise have been lost. During the European Renaissance from the late fourteenth until the early seventeenth centuries, rational though in an increasingly ordered and affluent society led to technologies such as the printing press the microscope and the telescope.
