The idea of saying the words and going on has a lot to do with trust in God. It is mentioned in Rav Nahman but goes back all the way to the Gemara itself and brought in the classical medieval Musar book אורחות צדיקים Ways of the Righteous.
To me it seems like a way to learn not just Gemara but also Physics--but again only with trusting God that you do a small amount if effort and then God sends the blessing.
[But then you also need faith that such a path of learning is in itself worthy and needed. This was definitely the way of books of Musar based on Saadia Gaon. חובות לבבות for example. [Obligations of the Hearts.] However this was an argument in Musar itself. Certainly the disciples of Rav Israel Salanter saw no value and even negative value in any secular studies. I would myself make a distinction between exactly what type of secular studies we would be talking about. Any subject in a University which has the name "studies" attached to it is clearly pseudo science.
