GPS

When cars were first invented, something like an electronic map that "pin-points" you on the globe and could find the shortest route for you to take to get to your destination in your car would be rediculous, and would only be dreamed about by the people with the greatest imaginations. But today, this concept is reality, in fact, is being used by millions of people around the world right now. It's all done with something …

…they used to. Tours of cities are no longer needed as much. But since all this is so expensive, our memories, paper maps, globes won't become extinct, in fact they will be here forever. Technology is getting more complicated every day, and our lives are getting easier every day, creating less stress and more time. Navigation systems in cars, planes, boats etc. are a good way to prove it, and its all done by science.
