Well, thank you for that thought! I'm renaming 70-odd of my articles right now from "A Note On X" to "On X" as a useful compaction, and almost all the titles seem fine just deleting the existing initial two words.
Not that I'm claiming to rub shoulders with Darwin and pals.
You could even get rid of "On". Most people probably think Darwin's magnum opus is titled "The Origin of Species" anyway.
Easy tiger! I have to take this one step at a time! B^>
From the numerous oddly wrong answers and their votes, it seems that too many people just don't read.
