3.5 rounded up.

Note: this review is from a completly ignorant person when it comes to science (but wants to learn!)

While I found aspects interesting and fascinating, I'm afraid it didn't 'stick' well to my brain. This could be my (personal) AuDHD, but I found topics chosen by the author a bit tedious at times (such as the swimsuits and tires) while others very interesting (gecko toes and indigonous paint preservation).

Language and accessability slipped between understandable to complicated quite frequently, which was difficult and made me have to reread paragraphs a few times over.
