100 age of ChangesThis century has been one of many changes and incredible inventions. If a person was to cogitate about it, this century has taken us from horseback to fuel-injected horsepower, from gaslights to sodium-vapor streetlights, from crystal radios to digital television, from compasses to GPS navigation systems, from wood burning stoves to microwave ovens, from Victrolas to DVD players and of course from bitter air balloons to jet propulsion aircraft.In the past 100 days, we encounter made much advancement in all areas of society. The way pot live has changed drastically just in the past century. Technology in particular has advanced more in these last 100 years then all previous time combined. For example, because of the research done by many innovative and dedicated individuals such as the Wright Brothers who were the first to feature flight in a powered airplane, we are able to fly ball all oer the world in a matter of hours in jet propelled pressurized aircraft . One hundred years ago, the thought of man ready in a machine was insane. The Wright Brothers helped to realize the dream of manned flight. numerous years later, after the idea of manned flight becoming a reality, station exploration was the next step. In 1969, many people did non believe what happened. Neil Armstrong and Buzz Aldrin landed on the moon. They posted an American flag, explored, put in space rocks and came back home. Many Americans did not believe that the technology 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 technology over the last century is the change in the computer. In 1946, the first electronic computer called the ENIAC took up the space of a large room. Instead of using transistors and IC chips, the ENIAC used vacuum tubes. Compared to many computers now, the ENIAC is about as efficac ious as a small calculator. That may not be much, scarce it is a milestone because there would not be computers straightaway if it were not for the ENIAC. As the years passed, the computer became smaller and more powerful. Today, more than one-half of the American population has a computer in their home. The personal computers today are thousands of times more powerful than the most powerful computers cubic decimetre years ago.
