No, in mathematics log x or log(x) is a perfectly acceptable, perhaps
the predominant, notation for the base-e, natural logarithm.
In calculus books, ln x or ln(x) is typically used for that -- so as
not to confuse students who were taught that log means the base-10
logarithm.
O.T.: P.S. M.I.T. has an all-male a cappella singing group named the
"Logarhythms".
