What is the greatest gadget of the twentieth century?

I'll have to go with computers that dropped us right in to the on-line world. Pagers leading to cell phones (which have lead to smart phones) have been excellent too.

If the Internet counts as a "gadget" then that most certainly is the greatest. But if it doesn't then computers themselves opened up a new world of technology and affected every possible industry in a positive way.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
