"Einstein had created an unwieldy monster that in a way he couldn’t tame. He conjured up a theory reliant on mathematics in a curved space-time that still demands years of its students’ attention. Though he managed to use those tools, compared to his mathematician friends he used them clumsily. Isn’t that great? I love that. His fragility, his defiant brilliance in the face of his own limitations… He ploughed right past his inadequacy."
