I have personally never been able to do that! by saying "study" I don't mean doing "home work" or reading a book; I mean research. for example:
- trying to solve a difficult mathematical problem in the morning.
- composing music in that afternoon.
- writing story during the evening.
this is a bit funny but Leonardo da Vinci had done it before(the example I have given is not from his history)! This make me wonder if its really possible?
I have seen people who talk while solving a math problem, but I am not talking about people who solve problems in habit. I am talking about mathematical ideas where each new idea is different from others and need special attention every time. I believe that this type of problem solving ability cannot be made faster or habitual with attempts to solve various problems. Again: I am not talking about math homework.
my question is will diverting one's mind in vast fields of art rigorously affect his mental health or is it actually possible? If there had been a Newton there had also been an Einstein, Faraday; if there had been Beethoven there had always been a Mozart. Its obvious that Leonardo da Vinci had been an expert in more than one subject; but who else have been like him? No one! So is it practically possible to learn more than one subjects?
