  Describe an invention that changed the world

  You should say:

  What the invention was

  What it can do

  How popular it is

  Why it is an important invention

  Ok, let me talk about GPS, or more commonly referred to as the Global Positioning System, which I guess is the one creation that has greatly influenced the whole world. The mechanism of GPS, I suppose, is based on time and the known position of specialized satellites.

  I must admit that I don't have a clue at all about the exact time when it's created or the person who should be given credited for inventing GPS. But as far as I know, it has a history of quite some years. While originally a military project, GPS is now considered a dual-use technology, meaning it has significant military and civilian applications.

  Specifically, you see, it has become a widely deployed and useful tool for so many purposes: commerce, scientific uses and more importantly, facilitating everyday activities such as banking, mobile phone operations, and even the control of power grids. Take myself as an example, being a frequent traveler, I simply can't live without a GPS in my hand. Even if I'm in a middle of nowhere, GPS will quickly locate me without the need of internet access, pointing out the best route for me.

  Also, another great thing about it is the application in delivery of goods. GPS makes it possible for us to track our parcels 24/7, knowing where exactly the parcel is and when it's delivered to the place. This just can't be more useful for online shoppers.

  Actually, this world-changing invention has tons of other applications that I may not be able to list them all. Just picture the world without GPS, then no one would deny the fact that it has made our life much easier than before.
