I keep seeing quite a few topics popping up around the forum, regarding Physics, Chemistry and Biology. Wouldn't it be easier having a forum for topics like these to directly go in where they can get a quicker response; as opposed to posting them in the most appropriate forum where they still only loosely fit?

Well, they're basically sciences, we already have a category devoted to those type of topics here Space, Science and Technology

Ah, I didnt see that was a Science forum too...Sorry for the bother.
