My son Izhak held with the idea of learning in depth [also with fast learning--saying the words in order and going on but the to go back over that chapter many times.] ], and this message was conveyed to me by the Litvak world over the years, but it was not until recently I have taken this advice seriously [But there were some periods when I did more than ''just saying the words and going on.'']
However, whether in learning Gemara Tosphot or the Achronim like Rav Chaim of Brisk, Rav Shach or in Math and Physics, I am hoping to in fact concentrate on לימוד בעיון learning in depth. [But I ought to add that this is not meant to diminish the importance of ''bekiut'' fast learning--i.e. saying the words in order and going on. This complements the learning in depth. In the Litvak world this is understood in such a way that the morning hours are set for in depth learning and the afternoon hours are set for fast learning. ]
I also hope to print a few copies of my little booklet on Shas that my son helped me to write.
