This question has such a large and outstanding answer that in short, the use of scientific tools has made discoveries from astronomy (such as using satellites and probes to find the recent discovery of flowing water on Mars) and geology(such as using tools for excavation to discover lost civilizations) to science itself(like using lab equipment to discover new aspects of health and physics). Honestly, the term "scientific tools" is very vague, so any tools used in any department of science will bring many discoveries within that scientific field.
How about cars, radio, TV, and computers, just for a few examples.
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.
