How do I know my results are significant enough to be published?
I am a physicist and I have found a very common mistake that appears in every paper in my area of interest. I thought it would be nice to let the people know it should be corrected. However, it is a very simple mistake, very basic math. I thought at first I could publish that as a short letter, but then i realised it is not that significant probably. Or maybe it is. I don't know. So my question is how do i know whether it is important enough to write such a letter to a journal? Should I just let it go?
