We don't have "Pi" day here since to put the month before the date is counterpoint to how the dates here are written anyway... :)<br />I will recommend your previous post to a few bloggers I know, that is excellent advice! Thank you!<br />and also thanks for your comment on my red dress win...Carolynhttps://www.blogger.com/profile/03156106727490224625noreply@blogger.comtag:blogger.com,1999:blog-15350975.post-69644849787846581092012-03-14T13:08:05.717-07:002012-03-14T13:08:05.717-07:00@IrkaDblrka I agree that tau is unfortunate nomenc...@IrkaDblrka I agree that tau is unfortunate nomenclature. I prefer Palais formulation with the 3 legged \newpi instead.<br /><br />For TeX users, that looks like:<br />\def \newpi{{\pi\mskip -7.8 mu \pi}}<br /><br />http://www.math.utah.edu/~palais/pi.html<br /><br />To quote Palais:<br />"I was still cautious about not violating the design principle of non-conflict with existing uses, e.g. torque, time constants, and shear stress for τ, but began to seriously consider the proposal. Then, shortly before June 28 (6/28), I was also contacted by Michael Hartl to alert me to the impending release of the `Tau Manifesto'. My initial reaction to both emails was that no one needs my approval to make such a proposal, though at the same time it was very kind of them both to contact me for my involvement and support. The combined effect and independent arrival at the same conclusion by these two scientists forced me to rethink my opposition, and I eventually realized that though τ may conflict with previous use, it should not be difficult to avoid conflict in any future publication by choosing among the many reasonable alternatives whenever a torque or time constant is being discussed simultaneously. Therefore, I am pleased to lend my support to their case for τ and am honored to pass the torch that I truly inherited from predecessors like Hoyle to these and future advocates of more natural clarity in our notation for rotational measure! <br /><br />Since then, I have noticed another potential conflict that is still (3/14/2011) not mentioned on the Wikipedia page on Tau, the torsion of a space curve that occurs in the Frenet-Serret equations. Amusingly, as that latter page is now written, it uses tau both for torsion and as a dummy variable of integration! This either shows the risks of ambiguous symbols, or perhaps it shows that they are not a big deal, and can be understood in context, even in close proximity!"<br /><br />OTOH, &pi also has a conflict as it is also used for product notation.badmomgoodmomhttps://www.blogger.com/profile/11569728075698885020noreply@blogger.comtag:blogger.com,1999:blog-15350975.post-62089768901139855002012-03-14T11:14:06.734-07:002012-03-14T11:14:06.734-07:00I still love pi!

And second - one of the amazing things I learned is that pi^2=g (acceleration due to gravity)! How cool is that?!HoleyFiberhttps://www.blogger.com/profile/04708035057361881698noreply@blogger.comtag:blogger.com,1999:blog-15350975.post-3604402209105255832012-03-14T08:27:45.261-07:002012-03-14T08:27:45.261-07:00I love this!
