"When you look at particles smaller than atoms, things can get weird ... very weird. You are transferred to a place where particles can be waves, waves can be particles, and atoms are "up" and "down." This book explores what seems like science fiction but is mathematically and scientifically sound. So, get ready to dive deep into a world where codes are unbreakable, computers use atoms to process data, and hypthetical cats are dead and alive: this is the world of quantum mechanics."--Page 4 of cover
