Only in the last of the ten chapters does Penrose discuss the reasons for introducing the reader to a wealth of physics in the first nine chapters; since mathematicians all understand new mathematical theories in the same way, the mind can not be an algorithm implemented in the brain. Not only is the premise a falsehood nor does it lead to the conclusion (perhaps because of my simplification). Penrose shows that he has a completely different understanding of algorithms than I think most people do. I doubt that under his definition evolution would be an algorithm, whereas I am certain it is. In addition he literally wrote that 'another magical ingredient' is needed (to explain consciousness), and I do not believe in magic or the need for magic to explain the world. Neither do I believe in the need for an abundance of exclamation marks, they do not make any statement more true! For me, all this made reading the book disappointing. However, Penrose painlessly introduced me to some concepts from physics and his view on the mind is different from what I have read before.
