anyone make mention of this fact. Bob Palais wrote an excellent article

back in 2001. But the arguments that I've seen favoring Tau over Pi

were basically a matter of style and taste.

I agree that ideally tau should be used. Such things are important to

cut away the complexity from formulas, and to bring out uniformity,

something which in my experience always pays off, revealing structure

and diminishing the amount of errors. Actually, I'd imagine, although I

do not know, that the use of the tau has the symphathy of many

mathematicians.

But there's also some conflict in that if I change to use tau in my

papers, then the formulae will look odd to other readers, simply because

they have been reading pi for all their life. I know that if I saw tau

used in a Fourier transform, I would start looking for the meaning of

tau as a variable. And perhaps a bit sadly, this need to be understood

as well as possible may override ideality.

But I also think that this is one of those things which just need an

initial push. After a critical mass of mathematicians/scientists adopt

tau instead of pi, then the change happens naturally.
