If you ask me about the greatest discoveries in the history of five sort  you as follows: - First: the discovery of fire (as the first picture of the energy control) Photos ..
- The second: the invention of the printing press and paper (thanks to their role in documenting and disseminating knowledge among the people) ..
- And third: the discovery of electricity (enough to imagine our situation today without it) ..
- The fourth: the discovery of the principle of immunization against diseases / and with the same level of antibiotics ..
- The fifth is the advent of the Internet, which changed everything in our lives (and it has become our right to the date the history of mankind and say: pre or post internet )!
Notice how the Internet changed the ways of communication, trade and dissemination of knowledge and shorten the world in a small screen .. Note how the company originated, how much of the service are available, and how much of the programmer became a billionaire thanks to the Internet's ability to intraday presence and reach each place ..
