ampere-second Years of ChangesThis century has been one of creationy changes and incredible inventions. If a soul was to think about it, this century has taken us from horseback to fuel-injected horsepower, from gaslights to sodium-vapor streetlights, from crystallisation radios to digital television, from compasses to GPS navigation systems, from wood burning stoves to microwave ovens, from Victrolas to DVD players and of telephone line from hot air balloons to jet propulsion aircraft.In the past vitamin C years, we have made much advancement in all areas of society. The behavior mess live has changed drastically just in the past century. applied science in particular has advanced to a greater extent in these last blow years then all previous time combined. For example, because of the research make by many innovative and dedicated individuals such as the Wright Brothers who were the set-back to sustain flight in a powered airplane, we are qualified to fly all over the world in a offspring of hours in jet propelled pressurized aircraft. One hundred years ago, the thought of man flying in a machine was insane. The Wright Brothers helped to realize the dream of man flight. Many years later, after the idea of work flight go a reality, space exploration was the next step. In 1969, many people did not believe what happened. Neil Armstrong and Buzz Aldrin landed on the moon. They posted an American flag, explored, collected space rocks and came back home. Many Americans did not believe that the engineering science existed to go that far. Today, several missions a year are launched using manned space shuttles that can be flown back to earth like gliders and reused on future space missions.Another example of the change in our engineering over the last century is the change in the computer. In 1946, the kickoff electronic computer called the ENIAC took up the space of a large room. preferably of using transistors and IC chips, the ENIAC used vacuum t ubes. Compared to many computers now, the ENIAC is about as omnipotent as a small calculator. That may not be much, but it is a milestone because there would not be computers right away if it were not for the ENIAC. As the years passed, the computer became smaller and more powerful. Today, more than half of the American population has a computer in their home. The own(prenominal) computers today are thousands of times more powerful than the most powerful computers fifty years ago.
