# Is there a database summarizing common notations? [closed]

Is there a database summarizing common notations? For example I read the symbol $$\kappa$$ and want to know which meanings are common e.g. sorted by different areas of science? I know that I could just open a standard book of the field I am concerned with and that notation varies widely. Just would be curious if somebody made the attempt to establish something like this since it could come in handy often when dealing with new fields of science.
