Is it possible to
CHANGE THE WORLD ?
Of course it's possible to change the world.
What's important is, to change it FOR THE BETTER!
The World is continuously changing, sometimes just a bit, and occasionally drastically. Various things change it. One way by which it gets changed is when someone invents something, which can't be uninvented. So, when doing some inventing, it's worth considering the kinds of things which will make life better and aren't easy to misuse. The usual way the world is changed is when someone thinks up a good idea and then a lot of people use that idea to push for change.
