Evolution of technology and important discoveries


 What is the technology? Is it only the design of new machines?
All of us know what is a rock and a lamp but, do you know that the rock was the object that produced light the first time?
What discoveries gave us the egyptians?
When appeared first glasses?
Have you ever compared the first telephone and the actual IPhone?
How was the first car?

 The technology is the set of objects, knowledge, activities, processes and sociotechnical systems.
Methods to do something, skills, innovations, tools, machines... all of them are victims of technology, from the new computer to the pencil and the process of its creation.

People created clothes (shirts), weapons (hand grenades, guns), tools (pencil, microscope, telescope, mercury thermometer, centigrade thermometer, rule, calculator, color paper...), instruments (piano), machines ( knitting machine, automobile, submarine, sewing machine...) and some objects (umbrella, pendulum clock, condom, oil lamp, hot air balloon, parachute, propeller, gas turbine...).
