Detailed books
I am looking for quantum physics books online for my gf’s birthday (or other natural sciences, could include chem, biochem, and electrical chem, or electricity as those are all her interest) and I want something that has good explanations and what not. Not too school-like. When I try to research into it, I feel like the description of the book is over-exaggerating how good it is. I was wondering if anyone had any personal favorites that helped them grasp difficult concepts in natural sciences? Thanks for any help!
