This is an excellent animation. BirdValiant 18:36, 8 October 2006 (UTC)
Would it be possible to have the wheel pause after completing one whole turn, so that it emphasises the fact that the marker on the rim touches the ground at zero and pi? Maelin (Talk | Contribs) 10:14, 30 October 2006 (UTC)
I think that's what the line going around the wheel is for. BirdValiant 03:27, 3 November 2006 (UTC)
- Yes, but it happens too quickly to see that the line is unravelling. If the wheel paused for a moment after completing the whole turn, it would be more obvious what had happened. Maelin (Talk | Contribs) 05:53, 7 November 2006 (UTC)
- My opinion is that by making the wheel stop, the fluidity of the animation is ruined. Maybe the line could be thicker, or somehow have more contrast than it already has. Or, the blue marker on the rim of the wheel could be remain in place at the instant it reaches pi, while still retaining the marker on the wheel itself. This extra blue mark might further emphasize that the marker touches at both 0 and pi, not that this isn't already obvious with the yellow and purple markers below.

- I just came here to comment that the animation is too fast, and have now seen Maelin's altered version. The pause is definitely a big improvement. Maelin, you should be bold and replace the existing image. I don't think anyone will have a good reason to complain. -- Earle Martin [t/c] 11:00, 1 April 2007 (UTC)

Hey, I agree, this a brilliant animation. It explains pi perfectly even for a dummy like me that can't do maths. ^_^--62.31.12.18 01:55, 20 January 2007 (UTC)
Good illustration! However, I would have the wheel and the animation just stop after one complete revolution. That would be the clearest in my opinion. ●DanMS 05:56, 20 January 2007 (UTC)
[edit] Way too cool but
Bravo! However, is the diagram accurate? It seems to suggest that pi = perimeter. __earth (Talk) 11:20, 20 January 2007 (UTC)
[edit] can I?

The diameter/circumference relation should be emphasized more clearly in the animation, like the fact that the diameter of the circle is 1. There is nothing in the animation that points to this relation which is, of course, the whole meaning of pi. —The preceding unsigned comment was added by 146.6.203.73 (talk) 20:09, August 22, 2007 (UTC)
I disagree completely with the above comment (that it is unclear that the diameter of the circle is 1) - the "intro" of the animation quite clearly shows, that the circle "fits" between the 0 and the 1 on the axis. This shows that the diameter is indeed 1. 212.242.167.26 (talk) 11:55, 25 March 2008 (UTC)
- Actually, I just noticed that the first four whel=els are slightly shorter that the rolling wheel. A little error like that can throw the whole thing off. —Coastergeekperson04's talk@May/07/08 13:22
