That this exists at all is wonderful in and of itself. What makes it more wonderful is that it's a positive review, made apparently without reservation by its writer, who said (among other things that made me blush): "These images capture with remarkable sensitivity the essence of Feynman's character." and "The Ottaviani-Myrick book is the best example of this genre [graphic novels] that I have yet seen."
But what blew the top of my head clean off is what you already figured out by looking at the cover...the reviewer is Freeman Dyson. If you don't know who that is you can look him up now, or better still pick up a copy of his book Disturbing the Universe and dig in. Because even though he appears in our book too, you shouldn't wait until August to read more about him.
