Which scientific Revolution Era led to the understanding of disease?

Question

a) telescope

b) microscope

c) thermometer

d)barometer

Answer 1

The microscope, which allowed us to actually see microoganisms and visually confirm their existence. But to be ornery, I have to say that the development of the telescope probably led to the development of the microscope. Take that as you will.

Answer 2

The microscope allowed scientists to actually view the microbes that they had speculated about.  Even before that, doctors made a tremendous breakthrough when they realized that the simple task of washing their hands and medical instruments greatly reduced deaths from infections.
