In the Talmud Shabat 63 we find in learning one should finish the book he is learning and then go back over it in detail. It even suggests learning by just saying the words and going on. לעולם ליגרס אינש אע''ג דמשכח ואע''ג דלא ידע מאי קאמר

The idea is that you present the contents of what you are learning to your subconscious, and automatically the process of synthesis takes place while sleeping or while doing other activities during the day.


we see also in Kant:

From the Internet Encyclopedia of philosophy


Kant characterizes synthesis as that activity by which understanding “runs through” and “gathers together” representations given to it by sensibility in order to form concepts, judgments, and ultimately, for any cognition to take place at all (A77-8/B102-3). Synthesis is not something people are typically aware of doing. As Kant says, it is a “a blind though indispensable function of the soul…of which we are only seldom even conscious (A78/B103)”.





I have thought that this would be helpful for Physics and  I found it helpful.  [At some point I decided natural sciences are important to learn based on the Guide of the Rambam. I would have done chemistry and biology also, but I decided if I would spread myself too thin I would not get anywhere. However at at the Polytechnic Institute of NYU, I did have to take chemistry also besides my major.
