Over the years I've seen a number of similar articles on pi and tau but I reckon this one is by far the most comprehensive. All have the same thread and it's a shame that tau and pi weren't reversed in meaning from the outset as clearly this would have simplified many things. For example (as the article mentions) the number of times I've see this ℏ=h/2π explained or alternatively its explanation omitted when it should have been explained is numerous. With tau, all that could have been omitted. Moreover, it seems to me that starting with tau is more logical in that a circle results from the rotation of the radius, still nothing will change as pi is so absolutely entrenched.
