Ultralearning

The following is the notes I took years ago on the book Ultralearning by Scott Young. The bombastic title and promise to learn virtually anything quickly makes it sound as if its the typical marketing-powered fluff-filled nonfiction book stores are overflowing with, but something about this book stuck with me. After finishing it I quickly went back and wrote these thoughts down. While I don't follow his layout of plans regularly, I have used it to guide a lot of my own self education.

I've successfully utilized it when I needed to refresh on mathematics for my Master's degree (a host of skills that atrophied sigificantly for the dozen years between undergrad and the masters). I've also used it to self-study subjects like Robotics and Deep Learning (though I did decide in the end to go for the Master's accreditation).

I share it here with hopes that someone finds it useful.
