I just bought the book "Gamma" by Julian Havil, a mathematician. In the introduction on page xix he uses ln for the natural log. >From this I conclude that the notation is in current use by mathematicians as well as engineers such as Prof. Sadoway at MIT.
Axiom can support this by defining a macro: ln(x) ==> log(x) Are macros supported in Sage?
