english: So Kaluza said to himself, Einstein has been able to describe gravity in terms of warps and curves in space -- in fact, space and time, to be more precise.
non_english: Kaluza si je rekel: Einsteinu se je posrečilo opisati gravitacijo z zvitostjo in ukrivljenostjo prostora - v resnici, bolj natančno, prostora in časa.
