Inventions to Research
Following are 40 great science inventions that almost made the top 100 list, ones that would have been ranked numbers 101 through 140. Certainly the inventions we would rank as numbers 101 and 102 are worthy of mention. Certainly they deserve as much attention as numbers 99 and 100. Some might place some of these next 40 in their versions of the top 100. Let this list of 40 additional great science Inventions serve as launching points for student research—both on the inventions and on their inventors.
