Respuesta :
I'm sorry, but I don't think this question can really be answered by anyone but yourself. I would say, if you'd like some direction as to where to start, I have these suggestions:
For Galileo, I would start by researching into his experiments with gravity. Prior to him, among others, objects were thought to behave based purely on mass. He did an experiment atop the leaning tower of pisa to disprove this.
For Newton, look into how his application of calculus and formulation of the laws of motion helped to refine and complete Kepler's laws of motion.
For Einstein, look into special and general relativity, and the existence of space-time and space curvature.
For someone less recognized that might deserve more credit than they do, I would recommend Eratosthenes.
I hope this helps; happy hunting!
