It's just the same useless argument every year. Just use what you want. I've been taught pi since secondary school. I understand it well and can use it effectively. Never have I sat there and thought, "if only there was a shortcut to multiplying this by 2". There's whole sites, videos and movements to get tau popular. I just personally don't understand the point.
- jobigoud 10y agoThat's exactly the issue. You are thinking in terms of pi, so it might be hard to see from a different perspective. It's like using a slightly off abstraction for a concept. At first you have to make a small effort to hold it in your head, then at some point it's committed and you can manipulate the concept directly.
- MichaelBurge 10y agoLet x be a randomly chosen real number in [0,1]. What does it mean to "manipulate x's concept" or "think in terms of x"? Do these phrases attach themselves to the real number, or to the expression language? If the latter, do you say two number-expressions are equivalent if applying some normalization function yields two equal expressions? Do you consider two number-expressions distinct if they evaluate to the same real number, but cannot directly be related to each other? For example, let: S = { (x, e^(ix) + 1) | x in R, x > 0 }, T = { x | (x,y) in S, y = 0 }, c1 = min(T), c2 = 6 * sqrt(sum(n^-2, n > 0)) If my memory's right, c1 and c2 evaluate to the same real number which happens to be equal to Pi. What does it mean to manipulate c1's concept or think in terms of it? Does c1 have the same concept as Pi?
- gravypod 10y agoThis isn't to save time multiplying by two. This is to uniform a hole slew of previously unrelated equations that can now be represented similarly.

- gravypod 10y agoI don't understand your comment. Have you watched the video linked within this post? This video is very good at pointing out many of the benefits of tao. [0] [0] - https://www.youtube.com/watch?v=H69YH5TnNX https://www.youtube.com/watch?v=H69YH5TnNX
- jeffwass 10y agoYou wrote "This is to uniform a hole slew of previously unrelated equations that can now be represented similarly." You seem to be saying that introducing a new constant tau=2pi and redefining a slew of previously unrelated equations in terms of tau instead of pi is suddenly going to make them "uniformly represented". I don't understand why they're not considered uniformly represented when defined just as consistently using pi?
- gravypod 10y agoHave you watched the linked video? If not I will not be able to explain what's going on as well as the presenter. He is able to show that many common physical calculations for volume or area all relate to the same generic form. He also is able to present many other cases where pie wins out. It is very much worth a watch.

- Bromskloss 10y agoI use 1.07 pi; it should be the same, as it is only a matter of convention.
