As a Chemical Engineer in training I loved this book.
I read it twice and got the audio book.
A decent read, not the best in the Horus Hershey. Please fixes the typos: No quotations, but < or > signs on these pages: 161, 2 on 164, 170, 173, 184, 2 on 192, 200, 2 on 224, 268, 272, finally 3 on 273. Those need to be fixed, especially, after charging $16 it should have no errors.
meh. Kinda lame
