text: what happened to all the questions? up until about a week ago, there were always about 10,000 unresolved questions in this category (sci and math).  suddenly there were about 5,000.  i wonder if they just removed the ones that keep repeating (about blue sky, chicken/egg, etc) apparently this could be cause by one of two of my more probable theories; either people have just lost interest in science and mathematics, or as you have stated before yahoo has got rid of all the repeating ones.
