Rav Nahman [of Uman and Breslov] emphasized saying the words and going on. But his approach was towards the Oral and Written Law. In fact he gave a list of what one ought to finish every years in such a fashion, the two Talmuds, Rif, Rosh, all the Midrashim etc.
But based on some Rishonim [medieval authorities] I expand that to include Physics and Mathematics.[Not all Rishonim agree].
Now one one hand R. Natan the disciple of Rav Nahman held one ought not to learn these subjects at all. To him they were all in the category of "outside wisdoms". In Sanhedrin there is a list of things for which one loses his or her portion in the next world. One of them is he who reads "outside books".
The way I usually deal with this was to apply what Rav Nahman had said about doctors to the issue. Rav Nahman strongly turned people to avoid doctors. However when a true vaccine came out in those days he said one must take it. So avoiding doctors did not refer to true medicine. In those days oxygen had not even been discovered. Doctors were still going with the four humors of the ancient Greeks and blood letting.[ the four humors—blood, yellow bile, black bile, and phlegm].
So my feeling about this is his objection against outside wisdoms was pseudo man made wisdoms. Not true Physics in which the Glory of God is revealed.
