Consciously and systematically Klein sought to enthral me with the problems of mathematical physics, and to win me over to his conception of these problems as he had developed it in lecture courses in previous years. I have always regarded Klein as my real teacher, not only in things mathematical, but also in mathematical physics and in connection with mechanics.
Sinasadya at systematically Klein sought upang maalipin ako sa mga problema ng mga matematiko physics, at upang manalo ako sa kanyang mga kuru-kuro ng mga problemang ito bilang niya binuo ito sa panayam ng kurso sa mga nakaraang taon. Ako may palaging regarded Klein bilang aking tunay na guro, hindi lamang sa mga bagay-bagay matematiko, kundi pati na rin sa matematika at pisika na may kaugnayan sa mechanics.
