I actually asked a question with the homework-and-exercises tag. Then, I was searching some question with the tag. I had visited 50 pages. Most of the questions don't have answers. And, most of the questions have a low number of views. But, why don't people come to answer those questions when they see the homework-and-exercises tag?
There are a lot of physicists either. But, no one comes to answer those questions. What's the reason of it?
