Point well made and taken.
Although in many of the uses of e^(pi*i), we want it as -1.

Tough luck for grade school students if this change does make its way. | ||

Sine Cosine Tangent Sine Three Point One Four One Five Nine This rhyme helped me so much when I first learned about Pi. For the sake of this rhyme, please keep Pi or else you will ruin my childhood. | ||

Pi is how many diameters needed to equal the circumference of a circle. It's awkward if we just say "tau is twice the number of diameters needed", because it's more arbitrary (and one wouldn't get why we used two circumferences instead of one until they learned "2pi" vs "1tau"). | ||

I remember using it in physics for things, which I want to say rotational acceleration or something close to that, but memory was never my strongest element. Personally I think they should just stack two pis on top of each other and call it something new. This "tau" is merely two pi so it makes more sense anyways. Then again I hate Greek letters with a passion so any opportunity to avoid them is a win. | ||

Then again I hate Greek letters with a passion so any opportunity to avoid them is a win. The article pretty much explains it. A circle has a total measure of 2 pi radians, so proportions become complex and weird. Having 1 Tau radian instead is much more easier. Like a quarter of a circle becomes a quarter of a pau radian. | ||

Really good explanation of why tau is better than pi. EDIT: And something interesting I just found | ||

i dont know enough about mathemathics to judge if this is a good change or not however, i think in general it would be much better to get rid of stupid stuff that people got used to eg: non-metric system, timezones, writing dates the american way (like they did with 6/28 even in this text), qwertz keyboards, umlauts (öäü) and ß in german, similar letters in skandinavian languages and most accents in spanish italian and french, backward compatibility in computer systems, etc etc etc also there is a lot of stuff that could easily be improved if you dont give a shit about tradition: rules for plenty of really popular sports could need improvement (football comes into mind), same for board games (chess) simplify and optimize with no regard to tradition, if we didnt have people do that in the past (thank you napoleon) we would still be stuck with even more old baggage than we are | ||

I'm questioning the word choice not the reasoning behind it. | ||

It only looks like a T if you don't make the hat thing squiggly like a ~ lol. BTW as far as other tau uses go, We used the symbol a lot in my abstract algebra class when studying homomorphisms, isomorphisms, galios groups, etc. Although that was be the use of our professor because he seeming to like tau and lower case sigma the most for those types of things. Oh, and I've seen it used for the golden ratio like twice ever, because phi is so popular for it instead. | ||
