This book was a recommendation from my engineering intern mentor. She talked about how it is filled with true technical information on chemistry, electricity, physics, and biology. Such that all her engineering friends love the book, since I guess we’ve touched on the subjects and understand them. When I read though it, I found it to be true. The almost off topic, first person view of the stranded astronaut going over technical calculations and considerations is highly fascinating. The plot itself is good as well, definitely a fun read.
