Here is a short list from Australia not enough space here
ultrasound, the bionic ear, the first plastic spectacle lenses, the electronic pacemaker, the multi-focal contact lens, spray-on artificial skin and anti-flu medication
man's first powered flight was not accomplished by the Wright Brothers. Instead, it was accomplished in 1894 by Australian Lawrence Hargrave, using four box kites.
1838 – Pre-paid postage – Colonial Postmaster-General of New South Wales, James Raymond introduced the world's first pre-paid postal system, using pre-stamped sheets as envelopes. This post-dates Rowland Hill's 1837 recommendation for the introduction of pre-paid stamps (the "Penny Black") in Britain, but pre-dates their first issue in 1840.
1843 – Grain ******** – John Ridley and John Bull of South Australia developed the world's first grain ******** that cut the crop then removed and placed the grain into bins.
1856 – Refrigerator – Using the principle of vapour compression, James Harrison produced the world's first practical ice making machine and refrigerator.
1874 – Underwater torpedo – Invented by Louis Brennan, the torpedo had two propellers, rotated by wires which were attached to winding engines on the shore station. By varying the speed at which the two wires were extracted, the torpedo could be steered to the left or right by an operator on the shore.
1876 – Stump jump plough – Richard and Clarence Bowyer Smith developed a plough which could jump over stumps and stones, enabling newly cleared land to be cultivated.
1877 – Mechanical clippers – Various mechanical shearing patents were registered in Australia before Frederick York Wolseley finally succeeded in developing a practical hand piece with a comb and reciprocating cutter driven by power transmitted from a stationary engine.
1889 – Electric drill – Arthur James Arnot patented the world's first electric drill on 20 August 1889 while working for the Union Electric Company in Melbourne. He designed it primarily to drill rock and to dig coal.
1892 – Coolgardie safe – Arthur Patrick McCormick noticed that a wet bag placed over a bottle cooled its contents, and the cooling was more pronounced in a breeze. The Coolgardie safe was a box made of wire and hessian sitting in water, which was placed on a verandah so that any breeze would evaporate the water in the hessian and via the principle of evaporation, cool the air inside the box. The Colgardie safe was used into the middle of the 20th century as a means of preserving food. 
1894 – Powered flight – Lawrence Hargrave discovered that curved surfaces lift more than flat ones. He subsequently built the world's first box kites, hitched four together, added an engine and flew five metres. Hargrave corresponded freely with other aviation pioneers, including the Wright Brothers. Unlike the Americans who commercialised their ideas, Hargrave never patented his. Because it p
Ancient Egypt with building engineering amongst other things.
Key advances in Science and Technology, Medicine, Medical Devices, AreoSpace, etc. can be attributed to work completed in the US. A substantial part of this work was completed by persons from around the globe, but US resources were needed to get the work done.
at this stage, the world and information is the size of a tea cup, isn't it.?
USA, definitely. Almost everything that defines modern technology came from us. Electricity and electric lighting, powered flight and mass produced autos, too much medical tech to name here, the world's first reusable space craft, nuclear power.
i want to say the US created (or were created by companies operating in the US)but they are all built and produced in other "cheaper" countries
well i guess the easyest is computer items from apple and microsoft
but there are lots of parts to computers and also methods and software
Steam Engine, TV, telephone, the deep fried mars bar
Telephone? Mr. Bell, he was a Scot, no doubt, but that first call was on Canadian soild, at Bell's home. However, Elisha Gray an American invented the phone at the same time and was only a few hours behind Bell to the patent office.
Did I mispeak? Mr. Bell did, a Scot living in Canada completed this work first I thought.
I'm Welsh not Scots and have no bias in this debate. What I do have is an avid interest in inventors and inventions. This isn't a case of putting the US down it's a case of setting facts out which show the Scots to be the most inventive. Don't take my word for it do your own research. Inventions never tend to be blue sky leaps in technollogy rather a development of existing technologies with a number of competing inventors working on similar inventions at the same time. I think it's only fair as well to take into consideration the populations of the 2 countries as well.
China is a replicator, not inventor...well black powder, they have that so we can blame China for every bullet that was ever fired? Ha!
Well, sure china isntvery original nowadays, but chopsticks are genius xD and well... Lots of things back in ancient china. Well what about enjoying fireworks?
Though I have to admit my knowledge on this topic is rather limited because i'm only in highschool and I have not really researched it :) just saying.
