And the world Changed......

wheel!

Almost every thing invented is important. If there is no computer and internet, People like we can not be here. Everything has importance.

hi,we can't specify which is the most important...when electracity was not there,the invention of electracity is most important.....same in the other inventions also,take trains,aeroplanes,radio,televisions...now COMPUTER rulong the world.in future what will be the important we don't expect..

I would have to say schools.It allows us to gather together to exchange thoughts and ideas which opens up new areas to search.It also eductes us to help improve ourselves and help others.

There are some who would say that the safety pin is one of the most important inventions....especially for children for many years before Pampers. Another one would be the paper clip. How about scissors now there's something that many of us could not live without. As others have said before me there is not just one thing that can be considered the most important for in one way or another they are all inner active. For example, to have electricity in your home you also need electric power plants, wire, light poles. Seems like a never ending circle.
