I have noticed and it must be a common experience for many of people that when they
put attention for extended period of time which could be as little as 15 minutes
or could span over days something occurs a deeper understanding of the subject etc.
This has been mentioned by great scientist like Newton etc attributing his scientific
discoveries to ability to put attention on a subject for longer period of time.
I wanted to know if some psychologist has done some research over this area
What exactly is this attention and what results from it. At one level it seems mysterious
Any references/books/examples etc.
