The U.S. Librarian of Congress, who's in charge of archives of copyrights, was asked to list the ten inventions and innovations most meaningful to human life today. Can we get all ten? Give it a try. You can nominate any number you wish. You can also suggest which number each should be on the list, the most important being #1.
Think in terms of recorded history. For each invention and innovation on the list, it's possible to point to specific individuals who made it possible in a modern sense, so such inventions as fire, the wheel, steel, houses, etc. are not included.
