In the Russian language there is such a phraseology “gnawing the granite of science”, which means to study a lot and learn science.
Somewhere there is even a real monument made of granite and an imitation of a bite is made on it.
Idk if the concept of “granite of science” exists in English, I didn’t find it, so I could not translate the tablet into another language.
