What invention in Ancient China has had the most influence in modern day America?

There are probably thousands of inventions that have influenced the West, China also invented many inventions centuries prior to the West inventing them on their own. Like Paper and Printing. But "The West" generally stands for all first world nations, you are specifically asking for America. I think the most "influential" to modern day America is the Chinese invention of Gunpowder.

I'm not from America and from the outside looking in America is painted as a very gun-happy nation and always starting wars...something you wouldn't be able to do as effectively without sweet sweet gunpowder. From PBS: http://www.pbs.org/wgbh/nova/lostempires/china/age.html ---- NOVA: How did the Chinese invention of gunpowder move from East to West? Yates: Although scholars often consider the Song Dynasty to have been very weak, its use of gunpowder was the reason it was able to hold off the Mongols for many decades.

Eventually, the Mongols were able to capture Chinese artisans and use the latest gunpowder technology against the Chinese. The Mongols used those people who had a special knowledge of technology and employed them in their own armies as engineers. They carried that technology to the West very rapidly because it was very helpful in their conquests.

What was interesting with this transfer of technology is that it goes both ways. After the introduction of the cannon and gunpowder to the West, Westerners very quickly became expert with cannons. They cast bronze cannons that were eventually much better than those the Chinese could produce.

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.
