One useful, current invention is the GPS. The GPS stands for global positioning system and was created by a number of people, among them were Ivan Getting, Bradford Parkinson, and Roger Easton. The GPS has changed the world greatly. When you are traveling and are unfamiliar with an area, you can just type the address into the GPS and it tells you exactly how to get there, step by step, street by street. Instead of getting worked up and frusturated about not knowing where to go, the GPS helps put people at ease.
