Pi has worked elegantly for a long time and so I don't feel there is a need to change the constant because we often see 2pi. | ||

I belive that the only thing holding this back is the us of "tau". That is extremely counter productive, using an inefficent name for an efficent symbol cancels the progress entirely. | ||

They have exactly the same value (that means all the equations are the same), but with the added benefit that you don't have to rewrite any textbooks. | ||

Your lower case t needs the little hook on the end of it, because otherwise it's too easily mistaken for a plus sign. Upper case T and upper case Tau look too similar, and is pretty much exclusively used as a temperature variable. | ||

It is extremely inefficent, change is sometimes good. I belive that the only thing holding this back is the us of "tau". That is extremely counter productive, using an inefficent name for an efficent symbol cancels the progress entirely. That comparison is almost apples and oranges. | ||

Changing this to Tau is so much more them just removing a 2 in equations, and anyone who has had to go through this uncomfortable learning period, where you learn that three quarters of a circle is equivalent to 3 halves of pi, would agree with me. Some of you don't understand how this change would make measuring angles so much more intuitive. I definitely support this change. Why didn't you just memorize it as 2pi*3/4? This feels like a teaching plunder to me to be honest (you should be angry at your math teacher). If someone really wants to create a new constant that is just twice as much as the previous one, then tau isn't really the best symbol for it in my opinion (it's rather widely used in many places for other things). | ||

Some of you don't understand how this change would make measuring angles so much more intuitive. I definitely support this change. Did it ever occur to you that angles greater than 180 degrees are used considerably less often? So in terms of measuring angles, it's not so bad. How is that more intuitive anyway? Either way you have to understand the equation. Now it's just "tau radians" rather than "2pi radians" but it's still 6.28 radians or whatever. I don't see how this makes radian measure any better. If anything, I think it makes it uglier as pi/12 and pi/24 would be further broken down to tau/48, and it just makes these numbers way bigger and bulkier. You try to make one thing pretty, it will make others ugly. There's no real point. | ||

This is cyrillic P: ![[image loading]](http://upload.wikimedia.org/wikipedia/commons/thumb/f/f7/Cyrillic_letter_Pe_-_uppercase_and_lowercase.svg/100px-Cyrillic_letter_Pe_-_uppercase_and_lowercase.svg.png) This is cyrillic T (italic): ![[image loading]](http://upload.wikimedia.org/wikipedia/commons/thumb/0/0b/20-Russian_alphabet-%D0%A2_%D1%82.svg/220px-20-Russian_alphabet-%D0%A2_%D1%82.svg.png) Forget Tau. 2pi should be called Ti. And it doesn't mean pi should be abandoned. There are already whole bunch of constants and whatnot widely used, that are just some other constants multiplied by even more constants. One such is Planck's constant and whatever h-bar is called: ![[image loading]](http://upload.wikimedia.org/math/1/9/3/193d2e97a5b0a6da8ec1ed1105a2d8e5.png) | ||

EDIT: And this is not even remotely similar to making the switch to the metric system. | ||

I might be wrong tho as it could bring confusion and disparity in formulas used globally. | ||

If the vast majority of scenarios in which Pi was used involved multiplying it by two then maybe but as is its just going to add division everywhere instead of multiplication which really isn't better. | ||
