I remember reading a remark on number theory that went something like this: "there is plenty of material in this topic for an $n$ semester course without having to repeat oneself".
Have you read a sentence of this type once? If so, would you be so kind as to tell me where it is that I can find it? Quite possibly, in the version of the quote that I originally read the writer had $n=100$.
Thanks in advance for your help with this little question of mine.
