Hinton was one of the people who invented backpropagation, which has let neural nets be as powerful as they are today. Somehow, despite his brilliance and intimate familiarity with backpropagation, his explanation of it is stunningly clear and simple. I'm thoroughly enjoying this course and recommend it to anyone who wants to build their own neural networks.

"If you can't explain something simply, you don't know enough about it. You do not really understand something unless you can explain it to your grandmother." - Some German dude :)

C.S. Lewis? "Any fool can write learned language: the vernacular is the real test. If you can't turn your faith into it, then either you don't understand it or you don't believe it."

That would be Uncle Al.
