how does the equation
cos(x)= (exp(ix) + exp(-ix))/2
and the sine equivalent fit into this? Clearly exponentials are not restricted
to angles ... indicating that x (and by implication angles) have no dimensions.
Marc Schiltz's previously cited Taylor expansion demonstrates this even
Of course, for SI political correctness we should be using nm^2 anyway. This
would add more confusion to a situation that most people don't worry about
anyway.

Dear Fred
A really nice video that would be great for giving non-crystallographers
(including colleagues and 1st year students, and perhaps also friends and
family) an overview of what we do. Thank you for pointing it out - and of
course very many thanks to Dominique Sauter for making it. I am

display your coordinates in rasmol
