I'm asking this question right now due to the fact that a lower back problem has made it very difficult for me to do much but lie down for large sections of the day when it flares up, and the fact that it is quite difficult to take notes when lying on your back.
How important would one say taking notes is to the mathematical learning process? What other ways are there of learning?
I've always taken notes in the past, but the development of this back problem has made it very painful to stand or sit longer than necessary at times, and during those times much of my sitting time must go towards doing the problem sets.
