Physics has hit a dead end in the quest for a theory of everything. The author traces how theoretical physics strayed from its path and is now drifting into esotericism with increasingly larger bubbles of speculation. With a witty and biting tone, enriched by entertaining anecdotes yet grounded in detail, he critiques contemporary physics and recalls the unanswered questions that have driven the great minds of the field. Despite, or perhaps because of, the critical tone, it is a fascinating and thought-provoking plea for science.
