Talk:Schlieren
From Wikipedia, the free encyclopedia
schlieren is the german word for the stringlike optical effect that you observe while dissolving sugar in your tea. You need schlieren optics to magnify these phenomena when these effects are not visible to the human eye.
Thie first thing you notice when you read this article is that schlieren is "not visible" which is a lie as mixing two clear liquids of different densities gives schlieren. The article should be changed to reflect that.
[edit] Merger Proposal
Will be helpful if schlieren photography is included in the flow visualisation section. IMO most of the reader are interested in the technique and having both the articles on the same page will be useful. myth 05:37, 24 January 2007 (UTC)
As a reader, I agree. When I was looking for Schlieren, I wanted to know both about the imaging technique and everything else. —Preceding unsigned comment added by 76.20.250.6 (talk)
As above. Though primarily interested in the imaging teqhnique, The photography is the same phenomenon and should be included in the main article.

I'm not convinced: the technique of viewing optical inhomogeneities is called schlieren photography, not just schlieren. I'd be in favour of moving some of the history of schlieren photography from "Schlieren" into "Schlieren photography" and keeping just a definition of schlieren and links to the various ways in which they are visualised in "Schlieren". It may be worth adding redirect pages from things like "Schlieren system" to the page "Schlieren photography" to ensure that people who want information about the optical visualisation technique are linked directly to it.

- Keep both pages, but include more information on the photographic method in Schlieren. Fifth Rider 22:26, 28 March 2007 (UTC)
