What do you think is the world's greatest invention of all time?

i would say the AC/DC motor. Invented far ahead of it's time and still being used today.  From air conditioners to alternators, even electricity from Hydroelectric dams. The best invention that's keeps on giving for free.  Generators that if you turn create electricity or if Fed electricity it would turn.  Works one way and same thing the other way around.  Also the wheel it was a beautiful invention and still is in use today.

it can not definitely be something other than human since only us have the capacity of thinking.this will be a classical answer but einstein was a good one. I do not want to say that he is the most intelligent one because he was a clever one but he also had the opportunity to show himself. there are lots of people who even do not have the opportunity to read, so in this case Einstein is best example to someone intelligent and able to show it to the rest of the world.

a lot of inventions coming from Brittain made [technical] history worldwide; whatsoever, in my opinion the biggest "product" or "invention" was the Shakespeare opus.

I think it could be possible. Even though some people ask why someone doesn't come back and tell us this, if you came back in time and told everyone this, how would you know what effect it would have? What would probably happen it that they when it's invented, nobody will be able to use it, and then it might as well not exsist. There's irony for you.

An invention: Cellborg ( http://www.livescience.com/technology/051027_cellborg_sensor.html ) massive potential to become useful in our lifetimes\n\nA discovery: new blackhole ( http://www.space.com/scienceastronomy/050509_blackhole_birth.html ) very little potential to become useful in our lifetimes, but oh so cool\n\nOffbeat: monkeys have accents ( http://news.yahoo.com/s/afp/20051129/od_afp/japananimalsoffbeat ) it has to do with monkeys and I personally find study language fascinating

The answer above by OneRunningMan is amazingly interesting.\n\nI doubt that his answer can be topped!

I think the most revolutionary invention of the 20th century has (go ahead and laugh) the perfection of the bidding rules for the card game "contract bridge" in the 1930's, because it represents a NEW FORM OF LOGIC which we will see in chaos theory and advancede mathematics over the next 50 years or so.\n\nWhat changed our fculture the most?  Physically, the automobile.  Artistically and intellectually, television.\n\nFor the 21st century, I think a form of artificial intelligence will emerge before the end of the century as the most revolutionary invention.  I think the end of America as the world's superpower will change our culture the most.\n\nIn the 20th century, I think the importation of German philosophy into our arts and culture following 1945 detracted more than any other thing.  But the modern focus-group, polled and surveyed political manipulation in elections and politics is a close second place.\n\nI think the major detraction from our culture in the 21st century hasn't even started yet.  I can't guess what it will be.

Yes! Most definetly! I think that there are hidden treasures within all of the world wonders. It's cool that you asked that question!
