Citing sources[edit]

Hi Ccrummer! On 4 August you made some edits to Lift (force) in the area of Coanda effect. Most of your edits were not accompanied by any citation or reference to the source of your information. Nominating where your information comes from is very important in an encyclopedia. At WP:Verifiability you will find the statement The threshhold for inclusion in Wikipedia is verifiability, not truth.

You wrote A common misconception about the causes of aerodynamic lift … Does this idea come from a quotable source, or is it your personal view of the matter? If it is simply your personal view it is known as original research. At WP:No original research you will see that Wikipedia is not a place for editors to write about their own ideas or their views on a subject.

You wrote about Raskin’s experiment. What is this, and what is the source of your information?

You wrote Coanda was an engineer, not a physicist, so his patent for a high-lift device is not accompanied by a rigorous theory that explains or documents a physical explanation for the cause of the effect. I don’t doubt that his patent was not accompanied by a rigorous theory that documents the physical explanation. Patent applications are not required to be accompanied by a rigorous documentation of theory. What is the source for your statement that this was because he was an engineer and not a physicist? This looks very much like your personal view of the matter. If so, it is original research and must be deleted from Wikipedia.

Please see WP:Citing sources to learn more about the need to quote sources, and how to do it. Happy editing. Dolphin51 (talk) 23:32, 4 August 2008 (UTC)[reply]
