[edit] 250,000

Some useless trivia - the Polish version of this article is 250,000th article on the Polish Wikipedia. Яǿǿ⁷² ✉ 08:58, 12 July 2006 (UTC)

But now significant longer than this one, that is some useless trivia, too ;-). Cheers, 83.238.66.225 06:33, 8 September 2006 (UTC)

[edit] Drop oscillation

I remember that there is a formula for the frequency of oscillation of a drop of non-viscous liquid close to sphericity, under the influence of the surface tension. But I don't remember the formula. Can someone put it on the page? At least for the first mode of vibration. Better still if there is a formula for other modes. (I have searched for such a formula on the Polish page - all I managed to grasp is that a drop is a kropla!) David Olivier 00:23, 11 September 2006 (UTC)

[edit] Drop/Droplet

If droplet redirects to drop, is it good practice to use drop in other articles?Trialex 05:26, 16 October 2006 (UTC)

[edit] chaos

The drops from a dripping tap do not drip with a constant frequency. In fact it is a chaotic phenomenon. The animation suggests the regular viewpoint instead. Not sure how to fix the animation itself. Maybe a simple note would be good enough. --MarSch 10:56, 29 October 2006 (UTC)

Not exactly constant, but close. Do you have a reference? — Omegatron 05:26, 6 December 2006 (UTC)

[edit] Drop size

Is this diagram correct? I was a little unsure about how and where to measure the angle of contact. Urocyon 06:34, 2 April 2007 (UTC)

Looking close. a is the radius of the tube (which could be made a little clearer), and \alpha is the Contact angle, in case anyone wants to double check. The downwards force is actually mg, not g, but I don't know how to best represent that on that diagram. LightYear 04:33, 3 April 2007 (UTC)

Just as a complete idiot here, but also, what units is radius supposed to be in; I'd assume meters, but then the weight of the droplet is coming out in milligrams, so I'm not so sure. Bilz0r 11:14, 1 June 2007 (UTC)
