I see no distinction from the first one. Both are essentially wrong.

>> He even doesn't know what number theory is.
> Better, but not good.

No, that's correct.

> Correct:
> He doesn't even know what Number Theory is.

No, that's wrong. Fields of study are not capitalized. *Courses* of
study may be capitalized ("I have Number Theory at 10:00 tomorrow"),
but that's not what this sentence is talking about.
