- Opps! The "Status: O" line was inserted by my mailer because it
- saw a line in John's article that started with "from ". This should
- have read:
-
- ...
- This again diverges as r -> 0 unless we fine-tune the bare mass and the charge
- so that e^2 = Gm^2, i.e. m = e/sqrt(G). But now let's steal an idea
- from general relativity and say that ALL energy contributes to the
- source of the gravitational field. Then we get
-
- m(r) = m + e^2/r - Gm(r)^2/r !
- ...

- Sorry, I thought if I didn't mention this someone might waste time
- wondering how "Status: O" was supposed to fit into the discussion!
