I'm deeply interested in how he was able to master Latin and Greek at such an early age. From memory I recall a quote about him having read pretty much all of Greek and Roman history from the original authors. Greek is a language with such a frighteningly large vocabulary I don't understand how he would be able to remember every word he ever looked up. Unfortunately it seems autobiographers are more interested in his scientific accomplishments and gloss over these facts in the by-and-by. I'd be very interested in knowing just how he learned and mastered language.
