Pi is wrong! Here comes Tau Day

Tired of all those 2 times pi in your mathematical formula? Then switch to tau!

Tau Day is on Tuesday June 28th!

WOUBROKEMYCODEWELLDONE? There is a 25 hidden somewhere at the top before the 15, you know.

[Kevin Houston]

Secret codes always go wrong somewhere but not usually on the first letter! How did you realize that there was a hidden message?

Tau (t) C = circumference r = radius pi (pi) d = diameter 1:37 t = 2(pi) pi = C/d t = 2pi = 2(C/d) t/2 = pi = C/d *How does this make sense in anyway? 4:19 pi*r^2 = t*r^2 is not true if you define t = 2pi AND Euler's method: e^pi*1 = -1 => e^t*i = 1 Can you explain how that proof works. I don't see how this is logical in any way if the value seems to change when the notation has a set value.

[Kevin Houston]

1:37 Makes sense to me. Can't see your problem.

4:19 Claim is that pi*r^2=(1/2)*t*r^2 not pi*r^2=t*r^2, etc

Back to exam marking for me...

[Thomas P]

this is so misleading you make me want to vomit!!!

[Kevin Houston]

I'd take you seriously if you said what was misleading about it.

[Kevin Houston]

Spooky. And some people say that the universe doesn't have a sense of humour.

As we all know, pi is about 3.14. What is 3.14 mirrored: PIE.

I never thought of it like this and I actually see the logic. I don't think it's a big enough deal to eliminate traditional pi because we do often use diameters, but I do think it is sound analysis and maybe we can slowly phase pi out.

In the midwest, Pi was considered 4.

Yeah, I'm surprised that Cantonese is dying out, since it has so many tones, it should fit with the universe cause the universe sounds like a fucking piano!

Mr. Houston, I think it would be nice if you'd make a reaction to The Pi Manifesto. At this moment I think Pi is still better than Tau, but I wouldn't mind a lot though. A reaction to the Pi Manifesto would show us whether the Pi or the Tau Manifesto is right.

[OrkTv]

If people manage to change the USA's imperial system to the metric system, replace the decimal system with a more fitting system (10=2x5, and 5 isn't a great number to play with) and get people to play with the ESDF key configuration instead of the WASD, then I might consider to changing pi to tau.

At this very moment, there are plenty of things that can be improved on.

People that argue using pi to find the area of a circle (radius squared times pi) is easier, but as you get more in depth to gets harder. Its

[Ovaldo Jhonson]

I can't EVER think than πr² isn't easier and faster than ½τr². It's not in my head, I refute it.
