"What one fool can do, another can." (Ancient Simian Proverb) - From Calculus Made Easy by Silvanus P. Thompson via https://news.ycombinator.com/item?id=14161876

I have refreshing my mathematics knowledge via videos made by Grant Sanderson.

Search "3blue1brown" on YouTube. I started with his Linear Algebra series (recommended here on HN)and then the Calculus series and finally the Neural Networks series. (highly recommended)

He is working on a Probability Series and I am supporting him on Patreon.
