Helgoland by Carlo Rovelli

 

Thanks to Jack for lending me the book. The relational interpretation of quantum mechanics was new to me. What I picked up from the book was that the view of distinct separate objects is out, along with the privileged position of an observer. This is because the Schrodinger's Cat story links merely me and the cat, but I must be observed too and so on in an infinite web of relations. Rovelli's idea is to get away from the split into Copenhagen versus many-worlds. I was interested to learn much more about Ernst Mach's philosophy and also to find out about Aleksandr Bogdanov. Not a book to read when you're feeling tired, though!
