Which subforums have the most unanswered posts?

[Stephen Tashi]

Just out of curiousity, which subforums tend to have the most unanswered posts?

I spend most of my time in the math sections, so I don't know much about the others. In visiting the General Engineering section today, I notice that there are a lot posts with 0 replies. (Is this evidence that practical problems are harder to solve than theoretical problems?)

You can find all threads without replies https://www.physicsforums.com/search.php?do=process&replyless=1&replylimit=0 (can be found at "Get Posts" -> "No Replies").
Practical problems often do not have a clear, simple answer, but I don't know that that influences the number of threads without replies.
