在探索理解量子引力的过程中，我们就像在广阔海洋岸边玩耍的孩子，偶尔发现一块光滑的鹅卵石或一个漂亮的贝壳，而真理的浩瀚海洋仍未被我们发现。
In the quest to understand quantum gravity, we are like children playing on the shore of a vast ocean, occasionally finding a smooth pebble or a pretty shell, while the great ocean of truth lies undiscovered before us.
Success is not final, failure is not fatal: It is the courage to continue that counts.
Silence is the language of the oppressed.
"La oscuridad siempre está ahí, solo hay que saber mirarla de frente."
