A friend sent me a new book about string theory by Dietmar Lüst (or Luest). Do not read it.
There is no original or interesting idea in the book. All is copied from other popularizing string theory books. He even manages to copy - copying text is a hobby in his country - only the worst ideas across the field: a lot about the book is on the multiverse.
I think every time a professor uses the word `multiverse', his salary should be cut by 20%. Lüst would be sleeping under bridges. He is an example of what happens when a smart man gets too much influence and no control (as most German professors): he goes bonkers.
