Isaac Newton used science to mathematics to find a theory of why things stop and go, instead of thinking God wanted it to stop and go he found a answer for it.
"If I am anything, which I highly doubt, I have made myself so by hard work" this shows he was a humanist because he didn't sit back and wait to die, he wanted to achieve something in his life.
Isaac Newtons laws of motion are a huge part in today's world. People use them to walk, run and other movements. Also they are used to create huge inventions such as cars, plains, trains and much more and this is huge part of the modern world.
