Compressed air vehicles
Having looked at air car and air engine, I think a merge should be discussed and will add a merge template to the articles. Thanks for the alert to the overlaps. Itsmejudith 09:32, 23 July 2007 (UTC)

One of your Book links is now a redirect.
Thanks for letting me know. I'll put it on the list of things that need to be improved with that book. --Andrewaskew (talk) 00:00, 16 September 2013 (UTC)

Infrared in solar radiance
Could you please help me understand the following sentence in Infrared? I believe it was contributed by you in a batch of big improvements in June 2013: "Sunlight, at an effective temperature of 5,780 kelvins, is composed of nearly thermal-spectrum radiation that is slightly more than half infrared." I just cannot make sense of the phrase "nearly thermal-spectrum." What could be a non-thermal spectrum of radiation? --Egmonster (talk) 02:34, 13 November 2015 (UTC)
 * Anything that doesn't look like the classical Planck's law thermal spectral radiance curve. Solar radiation approximates the Planck's law curve very well, but not perfectly. So it's a "near thermal" spectrum. Both the articles on Planck's law and Sun have comparisons of the Sun's actual spectral irradiance, and that calculated from theory for a black body.

 * So "nearly thermal spectrum" means "closely approximating the ideal spectrum emitted by a theoretical hot black body in vacuum"? Thanks! --Egmonster (talk) 17:05, 28 December 2015 (UTC)
