lowkey wish I was in school again. this is so cool

I LOVE this book! Where was it when I was learning algebra, years ago??

Thanks for posting. I wish there were many other books done similarly.

Selfishly, I'd love to see statistics, probability and advanced robotics displayed this way.

Very nice. Clean presentation that tells you what you need to know to move from one section to the next, which is more than I can say for most of these efforts.

The 'tooltips' are also a nice touch. If someone wanted to go nuts with this concept, they could allow the user to highlight any sentence, equation, or individual symbol to bring up an 'Explain this' popup option.
