Galileo Galilei
Improved the first telescope. His initial version only magnified 8x but was soon refined to the 20x magnification. It had a convex objective lens and a concave eyepiece in a long tube. The main problem with his telescopes was their very narrow field of view, typically about half the width of the Moon.

Issac Newton
His three laws of motion are:
1 every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
2 Force is equal to the change in momentum per change in time, for a constant mass, force equal mass times acceleration
3 For every action (force) in nature there is an equal and opposite reaction.
He created calculus, It is used to create mathematical models in order to arrive into an optimal solution. -
