I'm not against being open to things like ancient aliens, but I think the fact that squarerootofpi references that and astrology, etc puts it on completely different footing from tau, which the post we are discussing right now mentions being included in programming languages and scientific papers. [edit: obviously this says nothing about square root of half tau and its uses!] I put tau into my math-related code last year, and I have enjoyed the results (which are much the same as before, of course).
