[edit] 2003 - 2006 Talk items

I think the scientist of the anecdote is Albert Einstein, but am very unsure. -- Cimon Avaro on a pogo stick 05:16 12 Jun 2003 (UTC)

I am interested in the concept of turbulence as applied to air travel. I always thought the stratosphere was isothermal (horizontally) and smooth, so what is the origin of the "unexpected turbulence" that is often encountered by airliners?

The first picture looks interesting, but unfortunately I am completely unable to decipher what it is. It's obviously water and ... something. The caption gives no hint at all. Can someone elaborate?

It looks like water flowing over a ledge with a vertical post sticking up. The pattern you see behind it is the separation of water from the ledge 'behind the waterfall'. -Sprintstar 10:25, 14 October 2005 (UTC)

What would the world be like without turbulance? I bet it makes some fundamental things possible, but what? -Sprintstar 10:25, 14 October 2005 (UTC) does the turbulence in a pipe vary with age

Why does cigarette smoke switch from laminar to turbulent flow? Is it because the velocity of the smoke increases as it rises? --Wyckyd Sceptre 20:13, 26 September 2006 (UTC)

[edit] Turbulence during plane trips

Airplane turbulence is also what I was hoping to find in this page. If someone could make a page on how that specifically relates, that'd be great. 24.136.1.115 02:37, 19 November 2006 (UTC)

I think you're looking for Clear air turbulence. --Wjbeaty 12:05, 23 November 2006 (UTC)

What's all that?

It's called vandalism. It happens. Watchful editors (like yourself) keep an eye out for it and remove it. --Midnightdreary 13:16, 19 June 2007 (UTC)

I recommend the reader to refer the following references for further information:

WHY NO MENTION OF ROBERT KRAICHNAN?? His obit is in the NY Times yesterday, Feb. 29, 2008. Says he is generally considered the father of modern fluid turbulence theory. He was awarded both the Dirac Medal and the AIP Onsager Prize, among other recognitions. Recent experiments dramatically confirm his theory of turbulence in two-dimensional flow. Unless this is all wrong, someone who understands this field should add some comments about Kraichnan and his work. Also, there is currently no Wikipedia article about him, an unfortunate oversight.

[edit] sounds

I took the recording of what I think are turbulence sounds of a plane: [1] The sound quality is pretty low but I thought it might be nice to add it to the article anyways. The thing is: I don't know where to fit it ;-) Could anyone be so kind as to do this? Cheers, --Ludwigo (talk) 18:14, 11 June 2008 (UTC)
