It is incredibly illuminating and I also recommend it highly.

Upon completion of the book I was left with the feeling that there was no book in the universe too complex or erudite that I couldn't tackle.

Euclid’s Elements

I read In Defense of Food first and that seemed to stick with me too.

Buckminster Fuller's "Operating Manual for Spaceship Earth"

and "Understanding Media"

If all you've done previously was linear algebra and some discrete math, this book is probably better.

Gauss’ Disquisitiones

Newton’s Principia

His "Sets for Mathematics" is also good

Sets for Mathematics is more concise and probably goes into more depth by the end.

Marshall McLuhan's "Gutenberg Galaxy"
