I remember I watched Brian Cox do some maths. Think it was rocketry.

He had a bit of paper explained everything and said “In only a couple of minutes I have managed to work out what is required to get to the moon. I can only do this because Newton gave me the second law of motion, if I had to derive the second law myself I wouldn’t be able to do it in a lifetime. Newton was a genius”

It really put it into perspective for me. I wish I could find the clip.
